Noticing loose skin, acne scars, or stretch marks in the mirror can be frustrating, especially when skincare products no longer seem to make a difference. That is why many people turn to RF microneedling treatments that work beneath the skin’s surface to support collagen production and improve overall texture.
Two of the most talked-about options today are Secret RF and Infini. Both treatments combine microneedling with radiofrequency energy, but they are not exactly the same. Differences in technology, needle depth, treatment experience, and results can influence which option may be better suited to your goals.
If you are comparing Secret RF vs Infini, this guide breaks down how each treatment works, where they differ, and what you can expect before choosing a treatment plan.
What Is Secret RF?
Secret RF is a radiofrequency microneedling device designed to address common skin concerns such as:
- acne scars,
- uneven texture,
- enlarged pores,
- fine lines and
- mild skin laxity.
The treatment combines microneedling with radiofrequency energy, allowing practitioners to target both the surface and deeper layers of the skin during a single session.
The system uses fine needles to create controlled microchannels in the skin while delivering radiofrequency energy at specific depths. This process stimulates the skin’s natural healing response and encourages collagen and elastin production over time.
Secret RF is commonly used on the face, neck, and body and can be customized based on the patient’s skin condition and treatment goals.
Because needle depth and energy levels can be adjusted, practitioners can tailor the treatment for concerns ranging from superficial texture irregularities to deeper acne scars and stretch marks.
How Secret RF Works
During treatment, a handpiece containing multiple fine needles is applied to the skin. The needles penetrate the skin at predetermined depths, and radiofrequency energy is released into the targeted tissue.
The combination of mechanical needling and thermal energy creates a controlled wound-healing response. As the skin repairs itself, new collagen and elastin fibers are produced, which can improve skin texture, firmness, and overall appearance.
One of the distinguishing features of Secret RF is its adjustable treatment depth. Providers can modify needle penetration and energy settings based on the area being treated and the concern being addressed.
Deeper settings are often used for acne scars and stretch marks, while shallower settings may be selected for texture refinement and pore appearance.
What Is Infini RF Microneedling?
Infini is a radiofrequency microneedling system developed to improve skin texture, acne scars, wrinkles, skin laxity, and other signs of skin aging. Like Secret RF, it combines microneedling with radiofrequency energy, but it uses a different needle and energy delivery system that allows treatment at multiple depths within the skin.
The device uses gold-plated insulated needles to deliver radiofrequency energy directly into the dermis while limiting heat exposure to the outermost layer of skin. This targeted approach helps stimulate collagen remodeling in deeper tissue where structural skin changes occur.
Infini is commonly used for:
- Facial rejuvenation,
- Acne scar treatment,
- Skin tightening and
- Stretch mark reduction.
It can also be performed on areas such as the neck, jawline, and other parts of the body where skin quality and firmness are a concern.
How Infini Works
During an Infini treatment, a cartridge containing multiple insulated microneedles is placed against the skin. The needles penetrate to selected depths, and radiofrequency energy is released from the needle tips into the targeted tissue.
This controlled thermal energy creates small treatment zones beneath the skin’s surface. In response, the body initiates a repair process that promotes new collagen and elastin production. Over time, this remodeling process can improve skin firmness, texture, and scar appearance.
One characteristic often associated with Infini is its ability to reach deeper treatment depths than many RF microneedling systems. Because of this, practitioners may use it for concerns that originate deeper within the skin, including certain types of acne scars and stretch marks.
Treatment settings can be adjusted based on the treatment area, skin condition, and desired outcome, allowing a customized approach for different patients.
Secret RF vs Infini: Key Differences
Secret RF and Infini belong to the same category of radiofrequency microneedling treatments and are used to address concerns such as acne scars, skin laxity, uneven texture, and stretch marks. While both treatments combine microneedling with radiofrequency energy, they differ in their technology, treatment depth, patient experience, and maintenance requirements.
Understanding these differences can help determine which treatment may be better suited to specific skin concerns and treatment goals.
Technology and Needle Depth
The biggest distinction between Secret RF and Infini lies in needle insulation.
Secret RF uses non-insulated microneedles, meaning radiofrequency energy is emitted along the entire length of each needle. As a result, tissue is treated from the surface down to the selected depth, creating a broader treatment zone.
Infini uses insulated microneedles that release radiofrequency energy only at the needle tip. This allows energy to be delivered at a specific depth while minimizing heat exposure in the upper layers of the skin.
Both systems offer adjustable treatment depths, typically reaching up to 3.5 mm.
However, Infini’s insulated design gives providers greater control when targeting deep tissue structures, particularly for acne scars and significant textural irregularities.
Treatment Comfort and Downtime
A topical numbing cream is typically applied before either procedure, and most patients tolerate treatment well.
Recovery is generally similar for both devices:
- Mild redness is common immediately after treatment.
- Swelling may be present for the first 24 to 72 hours.
- Some patients notice temporary skin roughness or sensitivity during healing.
- Makeup is usually avoided for the first day unless otherwise advised by the provider.
- Most people resume normal activities within a few days.
The intensity of treatment often has a greater effect on recovery time than the device itself.
Results
The differences become more noticeable when looking at the concerns each treatment is commonly used to address.
Secret RF is frequently chosen for patients who have active acne as well as acne scarring. Because heat is delivered throughout the treatment channel, the treatment can affect a wider area of tissue, including structures involved in oil production.
Infini has become well known for treating deeper atrophic acne scars. Its insulated needle design allows energy to be deposited deep within the dermis, where scar remodeling takes place, while keeping the skin surface relatively protected.
Both treatments may help improve:
- Acne scars
- Fine lines and wrinkles
- Enlarged pores
- Uneven skin texture
- Mild skin laxity
- Stretch marks
Visible improvements develop gradually as collagen production increases over the weeks and months following treatment.
Sessions and Maintenance
The exact number of sessions depends on the concern being treated, the severity of the condition, and the desired outcome. Most patients require a series of treatments rather than a single session.
Patients seeking acne scar improvement or stretch mark reduction often require more sessions than those treating mild skin texture concerns.
Maintenance treatments may be recommended periodically to support ongoing collagen production and preserve results over time.
Infinix vs Secret RF for Stretch Marks: Which Treatment is Better?
Stretch marks don’t look and behave the same way for everyone, which is why both Secret RF and Infini end up being used in slightly different scenarios.
The deciding factor is usually not the device itself, but the age and depth of the stretch marks, along with how the skin has changed over time.
Newer stretch marks that appear red, pink, or slightly purple tend to respond better when there is still active blood flow in the area. In these cases, Secret RF is often chosen because its energy spreads along the needle channel, allowing a wider area of tissue to be stimulated in one pass. This can help improve both the colour and the surrounding texture, so the stretch mark blends more naturally into the skin.
Older stretch marks that have turned white or silvery are structurally different. They sit deeper and behave more like scar tissue with limited vascular activity.
Infini is often preferred here because it allows energy to be placed at a very specific depth, targeting the deeper dermal layers where long-term collagen rebuilding is needed. Instead of working across a broad zone, it focuses on restructuring the underlying framework of the skin.
Areas Commonly Treated
Secret RF and Infini are both designed for areas where skin quality, texture, and firmness are difficult to improve with topical products alone. While they are often discussed in the context of facial treatments, their use extends well beyond that.
The face is the most common treatment area, especially for concerns like acne scars, enlarged pores, fine lines, and uneven texture.
The cheeks tend to respond particularly well because acne scarring is often more visible there, while the lower face and jawline are frequently treated for overall tightening and refinement.
Outside the face, both treatments are commonly used on:
- Neck, for early skin laxity and creasing
- Abdomen, especially for stretch marks after pregnancy or weight changes
- Thighs and hips, where stretch marks and uneven texture are common
- Upper arms, for crepey skin or mild laxity
- Décolletage, where fine lines and sun-related texture changes appear
The choice of device and settings often changes depending on the area being treated.
Infini is often preferred for deeper, more defined concerns, especially acne scars on the cheeks and temples, where precise energy placement matters more. Secret RF is commonly used when the goal is broader improvement, such as overall texture, early scarring, or congestion across the face.
On thinner areas like the neck and chest, Infini is usually chosen for its controlled depth and lower surface impact, although both devices can be adjusted depending on sensitivity.
For the body, Secret RF is often used for newer stretch marks or diffuse texture changes on areas like the abdomen and thighs, while Infini is more suited to older, deeper stretch marks that need stronger dermal remodeling.
Secret RF vs Infini for Acne Scars and Texture
Acne scarring is usually where the differences between Secret RF and Infini become more noticeable in real-world results. Both treatments can improve pitted scars, uneven texture, and enlarged pores, but they tend to be chosen for slightly different scar patterns.
Infini is often used for deeper, more defined atrophic scars such as boxcar and rolling scars. Its insulated needles allow energy to be delivered precisely at the base of the scar, which helps target the structural damage beneath the skin without excessively affecting the surface.
Secret RF is commonly selected when acne scars are mixed with active breakouts, congestion, or widespread texture issues. Because energy is distributed along the needle channel, it can treat a broader area in one session, which is useful when scarring is not isolated to specific points.
In practice:
- Infini is often preferred for deep, stubborn, or long-standing scars
- Secret RF is often chosen for combination concerns (acne + early scarring + texture)
- Both can improve pores, roughness, and overall skin smoothness over time
- Results depend heavily on scar depth, skin type, and treatment settings
Ultimately, the better choice comes down to whether the priority is treating deep, isolated scars or improving overall texture with a broader, more combined approach.
Skin Texture Improvements with Secret RF and Infini
Improvements in skin texture tend to be one of the earliest and most consistent changes patients notice with both Secret RF and Infini, although the way those improvements appear can feel slightly different.
With Secret RF, texture changes are often more gradual and evenly distributed. Because energy is delivered along the length of the needle, the treatment tends to smooth out roughness across a wider surface area. This can be helpful for patients dealing with overall dullness, enlarged pores, or mild irregularities rather than isolated problem spots.
Infini, on the other hand, is often associated with more targeted refinement. By delivering energy at specific depths, it can address uneven texture linked to deeper structural issues in the skin. This is why it is frequently chosen for patients with more pronounced scarring or areas where the surface feels uneven in distinct patches.
Over time, both treatments rely on collagen remodeling to improve how the skin looks and feels. The difference is less about whether texture improves, and more about how the improvement is distributed across the treated area.
Acne Scar Treatment Differences
Acne scars rarely look or feel the same, which is why treatment choice usually depends on how deep and widespread they are rather than a fixed rule. Some scars are sharply indented and easy to notice in certain lighting, while others blend into a general uneven texture across the skin.
Infini is often used when scars are deeper and more defined. These are the types that feel slightly sunken when you touch the skin, such as boxcar or rolling scars. Because Infini can deliver energy at very specific depths, it is better suited for reaching the structural layer where these scars form.
Secret RF is more commonly chosen when acne scarring sits alongside broader skin concerns like rough texture, enlarged pores, or occasional breakouts. Instead of focusing on isolated points, it works across a wider area, which helps the skin look smoother and more even overall.
In most cases, the decision comes down to whether the concern is concentrated and deep, or more diffuse across the surface of the skin.
For more complex scarring, microneedling is sometimes combined with other in-office treatments such as subcision or laser resurfacing to improve overall results, especially when different types of scars are present at the same time.
Pore and Fine Line Reduction with Secret RF and Infini
Pores and fine lines are often among the first signs of changing skin quality, and both Secret RF and Infini are commonly used to address these concerns, especially when skincare alone is no longer enough to make a visible difference.
Secret RF tends to work well when enlarged pores are part of a wider issue like oiliness or uneven texture. Because it delivers energy along the length of the needle, it can influence a broader surface area, which helps the skin appear more refined and smoother over time rather than changing one isolated spot.
Infini is often selected when fine lines or texture changes are linked to deeper structural loss in the skin. By placing energy at controlled depths, it encourages collagen rebuilding in the dermal layers where skin support starts to weaken, which can gradually soften etched lines and improve firmness.
In both cases, changes are not immediate. The skin improves progressively as collagen remodels, which is why results often become more noticeable over several weeks rather than days.
Which Skin Types Are Suitable for These Treatments?
In some cases, skin type can affect whether Infini or Secret RF is chosen, especially when pigmentation risk is a concern.
Infini is often chosen for deeper skin tones because its insulated needle design limits heat exposure closer to the surface, which helps reduce the chance of pigmentation issues during healing.
Secret RF can also be used across different skin types, but providers usually adjust depth and energy more carefully in patients who are prone to discoloration or sensitivity.
In practice, the decision is less about “who can have it” and more about how aggressively the treatment should be performed for that individual skin.
Secret RF Skin Type Compatibility
Secret RF is suitable for most skin types, ranging from lighter to deeper skin tones. It is commonly used across a wide variety of patients because the treatment settings can be adjusted to match individual skin sensitivity and treatment goals.
Since it uses non-insulated needles that deliver radiofrequency energy along the full length of the needle channel, the upper layers of the skin are also exposed to controlled heat.
Because of this, practitioners usually take a more cautious approach in patients who are prone to pigmentation changes or have more reactive skin.
Secret RF is often selected when the concern is not limited to skin type but involves a combination of issues such as acne, early scarring, uneven texture, and mild laxity.
Infini Skin Type Compatibility
Infini is also suitable for a broad range of skin tones, including medium to deeper complexions. It is often preferred in these cases because its insulated needle design limits heat exposure closer to the skin surface.
This makes it particularly useful in patients where reducing the risk of post-inflammatory pigmentation is important, while still allowing deeper delivery of radiofrequency energy into the dermis.
Infini is frequently chosen for more targeted concerns such as deeper acne scars or stretch marks, especially when precision at specific skin depths is required.
What to Expect During and After Treatment
Most patients are surprised by how structured the process feels once they are actually in the clinic.
Secret RF and Infini follow a fairly similar treatment flow, but the experience is often shaped by the treatment area and intensity settings used.
Consultation and Skin Assessment
Before anything begins, the skin is assessed to understand the depth of scarring, texture changes, or stretch marks being treated.
This step helps determine whether Secret RF or Infini is more appropriate and how aggressively the treatment can be performed.
During this stage, the practitioner will also look at skin sensitivity, previous treatments, and healing tendencies.
This is where expectations are usually set around the number of sessions needed and how the skin is likely to respond.
During the Procedure
Once the skin is prepared and numbed, the actual treatment begins.
This is the stage where Secret RF or Infini is used to deliver radiofrequency energy into the skin in a controlled and precise way. The process is methodical and usually feels more manageable than patients initially expect.
- The skin is first cleansed to remove any makeup, oil, or impurities
- A topical numbing cream is applied and left on for around 20 to 40 minutes
- Once the area is fully numbed, the treatment begins using either Secret RF or Infini
- The device is moved across the skin in a controlled, section-by-section pattern
- Patients usually feel warmth and pressure rather than sharp pain
- Certain areas like the jawline, forehead, or around the mouth may feel more sensitive
- The session length depends on the treatment area, with smaller areas taking less time and larger areas like the cheeks, abdomen, or thighs taking longer
After the device passes are completed, the skin is usually soothed and protected before the patient leaves the clinic. Redness and warmth are expected at this stage and are part of the normal response as the skin begins its early healing process.
Aftercare and Recovery Timeline
After treatment, the skin goes through a short healing phase before collagen remodeling begins deeper in the dermis.
The recovery experience is usually similar for both Secret RF and Infini, although intensity settings and treatment areas can slightly influence how long visible effects last.
- Immediately after treatment, the skin often looks red and feels warm, similar to a mild sunburn
- During the first 24 hours, this redness is usually at its peak and the skin may feel slightly tight or sensitive
- By day 2 to 3, swelling and heat sensation start to settle, and the skin begins to calm down
- Between day 3 and 5, mild dryness or a rough “sandpaper” texture can appear as the skin starts renewing itself
- By the end of the first week, most visible side effects have faded, and the skin begins to look more even and settled
Over the following weeks, changes become more noticeable as collagen production increases beneath the surface. This is when improvements in texture, scars, and firmness gradually start to show rather than immediately after the procedure.
Choose Between Secret RF and Infini for You
Secret RF and Infini both deliver strong improvements in skin texture, scarring, and firmness, but they are often chosen for slightly different reasons rather than being direct substitutes for one another. The right option usually depends on how deep the concern is, how the skin behaves, and what kind of overall improvement is expected.
In simple terms, Infini is often selected when precision and depth control are important, especially for deeper acne scars or when pigmentation risk needs extra caution. Secret RF is more commonly used when the goal is broader skin rejuvenation or when acne, texture, and early scarring are happening at the same time.

FAQs
Is there an ideal age to start Secret RF or Infini treatments?
There is no fixed ideal age, as suitability depends more on skin concerns than age. Many patients start in their late 20s to address early signs of scarring or texture changes, while others begin later for more established wrinkles or laxity. The treatment is typically chosen based on skin condition and goals.
Can Secret RF or Infini be used on darker skin tones?
Yes, both treatments can be used on darker skin tones when performed correctly. Infini is often preferred due to its insulated needles, which reduce heat exposure near the skin surface and lower pigmentation risk. Secret RF can also be used safely, but settings are usually adjusted more carefully for higher Fitzpatrick skin types.
Are Secret RF and Infini suitable for mild skin laxity?
Both treatments can be used for mild skin laxity, especially in areas like the jawline, cheeks, neck, and abdomen. They work by stimulating collagen production, which gradually improves firmness over time. Results are subtle but progressive, making them more suitable for early or mild laxity rather than advanced sagging.
How soon can normal skincare products be used after treatment?
Most patients are advised to wait at least 24 to 48 hours before resuming normal skincare. Gentle, non-active products can usually be reintroduced first, while stronger ingredients like retinoids, exfoliating acids, and vitamin C are typically paused for several days depending on skin sensitivity and practitioner guidance.
