What is subcision with PRP and how does it treat acne scars?

Subcision with PRP is a two-step procedure that physically breaks up the fibrous tissue tethering depressed acne scars to the skin, then floods the treated area with concentrated growth factors to stimulate collagen rebuilding. Used together, the two techniques address both the structural cause of atrophic scars and the tissue-repair process that determines how well the skin fills back in.

Atrophic acne scars — the rolling, boxcar, and icepick depressions that sit below the surrounding skin surface — form because fibrous bands anchor the base of the scar to deeper tissue. Subcision targets those bands directly. A clinician inserts a small needle or cannula beneath the scar and moves it in a fanning motion, severing the tethers and releasing the depressed skin so it can rise toward the surface. The mechanical disruption triggers a wound-healing response, prompting the body to lay down new collagen in the space left behind.

PRP — platelet-rich plasma — comes from a small blood draw that a technician spins in a centrifuge to concentrate the platelets. Those platelets carry growth factors that signal skin cells to proliferate and produce collagen. Injecting PRP into the subcised area immediately after the procedure gives the healing tissue a biochemical push at the moment it is most receptive.

Clinical data support the combination. A study of Vietnamese patients with atrophic acne scars found that subcision combined with PRP produced measurable scar improvement across multiple sessions, with patients and clinicians both rating outcomes as meaningful. Key findings from that research:

• Scar depth and texture improved across rolling and boxcar scar subtypes, which respond better than icepick scars because their fibrous tethers are more accessible to the needle.
• Multiple sessions are standard. The protocol in the study involved repeated treatments spaced weeks apart — single sessions do not produce the same degree of remodeling.
• Side effects were manageable. Bruising, swelling, and temporary redness were the most common reactions; serious adverse events were not reported.

Results are not permanent. Collagen remodeling continues for months after each session, and most patients see progressive improvement over three to six months following a treatment course. Skin aging and sun exposure can affect long-term durability, so maintenance sessions are sometimes recommended.

Subcision with PRP is not a universal fix. Icepick scars and very deep fibrotic scars often need different or additional approaches. A dermatologist or licensed aesthetic clinician can assess scar type and depth to determine whether this combination is the right starting point.

What does research say about fractional microneedle radiofrequency for skin rejuvenation?

Fractional microneedle radiofrequency (FMR) shows measurable short-term improvements in skin texture, firmness, and overall facial appearance, with clinical evidence supporting its safety profile for facial rejuvenation — though long-term durability data remain limited.

A prospective clinical study on 5MHz FMR tracked patients receiving fractional microneedle radiofrequency treatments and documented statistically significant improvements in skin quality outcomes over the study period. Researchers reported an acceptable short-term safety profile: side effects were manageable and transient rather than severe or lasting.

The research specifically documents:

• Skin rejuvenation outcomes: The 5MHz FMR prospective study measured facial rejuvenation endpoints and found meaningful short-term efficacy — patients showed visible improvements in treated areas within the study window.
• Safety signals: Researchers in the same prospective study characterized the treatment as safe for facial use in the short term, with no serious adverse events reported during the observation period.
• What "short-term" means here: The study's own framing flags this as short-term evidence. That matters. It tells you the treatment works in the near window after treatment — it does not tell you results hold at one year, two years, or beyond.

The mechanism is straightforward. Microneedles deliver radiofrequency energy directly into the dermis, bypassing the surface. That targeted heat triggers collagen remodeling — the skin's own repair process rebuilds structural protein. Results build gradually. They don't appear overnight.

Current published evidence leaves several questions unanswered: how many sessions produce optimal results for different skin types, how long improvements realistically last before retreatment is needed, and how FMR compares head-to-head against other energy-based devices in rigorous controlled trials. These are fair questions to bring to a consultation.

Microneedling as a broader category does carry a growing evidence base. Research on dermaroller microneedling documents how mechanical needling stimulates follicular and dermal activity, which explains why combining radiofrequency energy with needle delivery is a logical extension of that mechanism.

FMR has real clinical support for short-term facial rejuvenation. The evidence base is still maturing. Anyone considering this treatment should ask their provider specifically what outcomes are realistic for their skin concern and timeline.

Can microneedling really help with hair loss?

Microneedling shows genuine, research-backed promise for certain types of hair loss — particularly androgenetic alopecia — though it works best as part of a combination approach rather than a standalone fix.

Clinical research gives this treatment more credibility than most people expect. A published review examining dermaroller-based microneedling found that the controlled micro-injuries the needles create trigger a cascade of wound-healing signals, including the release of growth factors that directly stimulate dormant hair follicles — see Role of dermaroller in hair growth for the full mechanistic breakdown. The scalp responds by upregulating platelet-derived growth factor and vascular endothelial growth factor, both of which play a documented role in pushing follicles from a resting phase back into active growth.

Here is what the evidence actually shows:

• Mechanism is real. The dermaroller review confirms microneedling activates stem cells in the hair follicle bulge region — the part responsible for regeneration.
• Combination beats solo use. The same source reports that microneedling paired with topical minoxidil or platelet-rich plasma (PRP) consistently outperforms either treatment used alone.
• Needle depth matters. Depths between 0.5 mm and 1.5 mm appear most relevant for scalp applications, according to the dermaroller review; shallower passes may not reach the follicle bulge, and deeper passes carry higher risk of scarring.
• Results take time. Patients in reviewed studies typically needed multiple sessions — often six or more spaced weeks apart — before measurable hair density changes appeared.

What microneedling cannot do matters just as much. It does not reverse scarring alopecia, where follicles have been permanently destroyed by inflammation or fibrosis. The dermaroller review focuses specifically on non-scarring conditions, and providers who suggest otherwise are overstating the evidence.

The treatment is low-risk when performed correctly. Redness, mild scalp tenderness, temporary shedding — these short-term side effects resolve quickly in most people. Infection risk exists with any skin-penetrating procedure, so sterile technique and single-use needle cartridges are non-negotiable.

Microneedling earns its place in a hair-restoration plan for the right candidate. It is not a miracle. It is a tool — one that works harder when a qualified provider selects it deliberately, pairs it with proven adjuncts, and sets realistic timelines.

What is dimpleplasty and is it right for you?

Dimples form naturally when a small gap or bifurcation in the zygomaticus major muscle tethers the overlying skin, pulling it inward during a smile. Dimpleplasty replicates that anatomy artificially. A surgeon makes a tiny punch or incision inside the mouth, removes a small core of tissue, then sutures the inner skin layer to the muscle — no external scar. According to a 2025 narrative review on dimpleplasty, the procedure is typically performed under local anesthesia and takes roughly 20–30 minutes per side.

What the evidence says about results:

• Early appearance: The dimple shows at rest immediately after surgery, which looks unnatural. The same review explains that this resting dimple fades over weeks as initial swelling and the fresh adhesion soften — the goal is a dimple visible only during smiling.
• Durability: Long-term retention depends on how robustly the fibrous adhesion matures. The review notes that some patients experience partial or complete fading of the dimple over months to years as the adhesion weakens — a known limitation surgeons should disclose upfront.
• Reversibility: Dimpleplasty is considered reversible in theory, but reversal requires a second procedure and outcomes are not guaranteed.
• Infection risk: Any intraoral incision introduces bacteria. A systematic review on antimicrobial sutures in plastic surgery (source) found that antimicrobial-impregnated sutures significantly reduce surgical site infection rates — worth asking your surgeon whether they use them.

Who tends to be a good fit:

People with fuller cheeks often see more defined results because there is more soft tissue for the adhesion to pull against. Very thin faces may produce dimples that look too deep or sharp. Age matters too — skin laxity increases over time, and a dimple created at 25 may sit differently at 45.

The honest bottom line: Dimpleplasty works. Results are real. Fading is also real, and no surgeon can guarantee a dimple lasts a lifetime. Talk to a board-certified plastic surgeon or oral and maxillofacial surgeon — not just a medspa injector — before deciding.

How do surgical safety measures like antimicrobial sutures affect cosmetic procedure outcomes?

Antimicrobial sutures meaningfully reduce surgical site infections in plastic and cosmetic surgery, and that reduction directly protects the aesthetic result you paid for. A wound infection doesn't just cause pain — it can distort healing tissue, create visible scarring, and undo the outcome your surgeon worked to achieve.

A systematic review and meta-analysis focused specifically on plastic surgery patients found that antimicrobial-impregnated sutures cut surgical site infection rates compared to standard sutures. That matters in cosmetic contexts more than almost anywhere else in medicine, because the margin for error is essentially zero — patients aren't just recovering from illness, they're expecting a precise visual result.

Here's what the research tells us about how these sutures affect outcomes:

• Infection prevention is outcome preservation. The plastic surgery meta-analysis confirms that antimicrobial sutures reduce infection risk, and infections drive poor scarring, asymmetry, and prolonged recovery — all of which compromise cosmetic results.
• The benefit is procedure-specific. Suture choice matters most in procedures where incisions close under tension or in areas with higher bacterial load: facial procedures, body contouring, and reconstructive work all fall into categories where the meta-analysis authors identified meaningful protective effects.
• Sutures are one layer of a broader safety system. Technique, sterile environment, and post-operative wound care all contribute. No single material guarantees a clean result on its own.

Cosmetic procedures like dimpleplasty — a minor surgical technique that creates permanent cheek dimples through a small intraoral incision — illustrate why infection control is non-negotiable even in "small" procedures. A narrative review on dimpleplasty details how the procedure's success depends heavily on precise tissue handling and clean healing; any disruption to that process changes the final appearance.

When you consult a provider, ask directly: what suture materials do you use, and why? A surgeon who can explain their infection-control rationale — including suture selection — demonstrates the kind of evidence-informed practice that protects your result.

Antimicrobial sutures are a clinically supported tool, not a marketing claim. They reduce a specific, measurable risk that has direct cosmetic consequences.

What questions should you ask your provider before booking a treatment?

Before booking any aesthetic treatment, ask your provider at least five specific questions about credentials, expected outcomes, side-effect profile, maintenance requirements, and what the clinical evidence actually shows for your skin type and concern. The answers will tell you more about a clinic's quality than any before-and-after photo on their website.

---

Getting those answers takes preparation. Here is what to ask — and why each question matters.

"What are your credentials, and who performs the procedure?"

Licensing requirements for med-spa treatments vary widely by state. Ask whether a physician, nurse practitioner, or licensed aesthetician will perform your treatment, and whether a physician is on-site or on-call. The person holding the device matters as much as the device itself.

"What does the clinical research show for this treatment — and for someone with my skin type?"

Push past marketing language. A prospective study on 5 MHz fractional microneedle radiofrequency found measurable improvements in skin texture and laxity, with researchers noting the treatment was well-tolerated across a short follow-up window — but they also flagged that longer-term durability data remain limited (PMID 42522676). A provider who cites actual study limitations is more trustworthy than one who promises permanent results.

"How many sessions will I realistically need, and how far apart?"

One session rarely delivers results. Microneedling for hair stimulation appears to work through repeated mechanical signaling to follicles over time, not a single treatment (PMID 42522488). Get the full course of treatment — and its total cost — in writing before you commit.

"What are the most common side effects, and what is your protocol if something goes wrong?"

Every procedure carries risk. Dimpleplasty, a minor surgical cosmetic procedure, carries specific complication profiles that vary by technique and patient anatomy (PMID 42528889). Ask the clinic what their complication rate is, what they consider a complication, and who you call at 10 p.m. on a Saturday.

"What results are realistic for my specific concern — not the best-case scenario?"

Research on subcision combined with platelet-rich plasma for atrophic acne scars showed meaningful improvement in scar appearance, but outcomes varied by scar type and depth (PMID 42539967). A good provider will tell you where you fall on that spectrum. Walk away from anyone who guarantees outcomes.

• Ask about credentials and who physically performs the treatment
• Request citations, not just testimonials
• Get the full treatment plan and total cost upfront
• Understand the side-effect protocol before you sign anything
• Demand realistic, individualized outcome expectations

FAQ

Is subcision combined with PRP safe for all skin types?

The published study on subcision plus PRP was conducted specifically in Vietnamese patients with atrophic acne scars and reported outcomes for that population (PMID 42539967). Safety and suitability can vary by skin type, scar depth, and individual health history, so a qualified dermatologist or plastic surgeon should evaluate your specific situation before recommending this combination.

How many sessions of fractional microneedle radiofrequency are typically needed?

The prospective study on 5 MHz fractional microneedle radiofrequency assessed short-term outcomes but did not establish a universal session protocol applicable to all patients (PMID 42522676). The number of sessions needed depends on individual skin concerns, treatment goals, and provider assessment—always discuss a personalized plan with your treating clinician.

Is dermaroller microneedling an effective standalone treatment for hair loss?

Research has explored dermaroller-mediated microneedling as a method to stimulate hair follicles and potentially support hair growth (PMID 42522488). However, the evidence base is still developing, and microneedling is often studied alongside other therapies. A dermatologist can help determine whether it is appropriate for your type of hair loss.

What is dimpleplasty and how long does recovery take?

Dimpleplasty is an elective cosmetic procedure designed to create the appearance of natural cheek dimples. A narrative review outlined various surgical techniques and noted that recovery experiences differ based on technique and individual healing (PMID 42528889). Prospective patients should discuss realistic recovery timelines and possible complications with a board-certified oral and maxillofacial or plastic surgeon.

Why do antimicrobial sutures matter for medspa or cosmetic surgery patients?

A systematic review and meta-analysis found that antimicrobial-impregnated sutures were associated with lower rates of surgical site infections in plastic surgery settings (PMID 42535096). While suture choice is a clinical decision made by your surgeon, understanding that infection-prevention strategies exist can help you ask informed questions during your pre-procedure consultation.

Are these cosmetic treatments suitable during pregnancy or while breastfeeding?

None of the studies referenced in this guide specifically evaluated these treatments in pregnant or breastfeeding individuals. If you are pregnant, planning to become pregnant, or breastfeeding, it is essential to disclose this to your healthcare provider before undergoing any cosmetic or minimally invasive procedure.
