Key Takeaways
- PRP works best for rolling and shallow boxcar acne scars — scar types that respond to collagen stimulation. It is less effective for deep ice-pick scars and does not work on raised or keloid scars.
- Results are not visible immediately after treatment. Meaningful scar improvement typically appears at weeks 8–12, with the full extent of results assessable 3–4 months after completing a course.
- A course of 3–4 sessions spaced 4 weeks apart is the standard protocol — a single session produces some collagen stimulation but not the cumulative remodelling effect of a full course.
- PRP carries lower pigmentation risk than ablative laser for darker Malaysian skin tones — making it a preferred starting point for clients with deeper complexions concerned about post-treatment hyperpigmentation.
- All before/after photos in this guide are real Casablanca clients, shared with written consent, photographed at consistent angles and lighting across sessions.
Before/after photos for aesthetic treatments in Malaysia are everywhere online — and most of them are either cherry-picked best cases, inconsistently lit, or taken at dramatically different distances between the before and after shot. This page shows real PRP results from real Casablanca Aesthetic clients, photographed at consistent angles and lighting at weeks 0, 4, 8, and 12, with honest outcome notes for each case — including what improved, what didn't, and what the next step was for each client.
What Types of Acne Scars Respond to PRP?
Not all acne scars are the same, and PRP does not work equally well across all scar types. Understanding which type you have is the most important factor in predicting your result before you book.
✓ Rolling Scars — Responds Well
Broad, wavy depressions with sloped edges. PRP's collagen stimulation effect lifts and softens these progressively over a course. Typically the most consistently responding scar type.
✓ Shallow Boxcar Scars — Responds Well
Defined edges, moderate depth. PRP can meaningfully reduce the visible depth and soften edge definition, particularly over 3–4 sessions.
~ Deep Boxcar Scars — Partial Response
More defined edges, greater depth. PRP improves surface texture and may soften edges but is unlikely to fully resolve deeper depressions alone — often combined with subcision or filler for full correction.
✗ Ice-Pick Scars — Limited Response
Narrow, deep, steep-walled channels. PRP cannot fill these from below. Typically requires TCA cross or punch excision for meaningful improvement.
✗ Hypertrophic / Keloid — Not Suitable
Raised scar tissue. PRP's collagen-stimulating mechanism would worsen rather than improve raised scars. Not recommended for this scar type.
What this means before you book
If you have a mix of scar types — which is common — PRP will improve the rolling and boxcar elements while having little effect on any ice-pick scars in the same area. Your doctor will map your scar types at consultation and give you a realistic outcome expectation for your specific pattern before you commit to a course.
How These Photos Were Taken — Our Protocol
Why Consistent Photography Matters
Before/after credibility depends entirely on consistency. A photo taken in dim indoor lighting at week 0 and bright window light at week 12 will show a dramatic "improvement" that is entirely a lighting artefact. Every client case in this guide follows the same protocol:
- Same camera and lens for every session
- Same distance and angle — front, left 45°, right 45° for each time point
- Same lighting setup — standardised clinic lighting, no window light, no flash
- No filters, no retouching — images are cropped and colour-corrected for white balance consistency only
- Photos taken before treatment begins at each session, not after

How to Read These Cases
Each case shows the client's scar type, sessions completed, photos at each time point, and an honest outcome note — including what improved, what remained, and what was recommended next where relevant.
Abby — Rolling Scars, Cheeks
3 Sessions Completed
Week 0 — Before
Week 4 — After Session 1
Week 8 — After Session 2
Week 12 — After Session 3
Outcome at Week 12
Visible softening of rolling scar depressions across both cheeks. Skin surface texture noticeably smoother under direct lighting. Scar visibility in natural light reduced significantly. Client continued with one maintenance session at month 6.
Darshini — Mixed Boxcar and Rolling Scars
4 Sessions Completed
Week 0 — Before
Week 4 — After Session 1
Week 8 — After Session 2
Week 12 — After Session 3
Outcome at Week 12
Rolling scar component improved significantly. Shallow boxcar scars showed partial softening. Deeper boxcar areas showed less change — client was advised to consider subcision for those specific areas as a next step. No post-inflammatory hyperpigmentation despite deeper skin tone.
Sabrina — Post-Acne Texture and Tone
3 Sessions Completed
Week 0 — Before
Week 4 — After Session 1
Week 8 — After Session 2
Week 12 — After Session 3
Outcome at Week 12
Significant overall skin quality improvement — surface texture smoother, post-inflammatory hyperpigmentation faded considerably alongside the scar improvement. This case shows PRP's combined effect on both scar texture and post-acne pigmentation when the two present together.
Honest Expectations — What PRP Will and Won't Do for Acne Scars
What You Can Realistically Expect
- Rolling and shallow boxcar scars: 30–60% visible improvement over a full 3–4 session course, with skin surface texture becoming noticeably smoother
- Skin tone and post-acne pigmentation: Often improves alongside scar texture, particularly for PIH (post-inflammatory hyperpigmentation) that coexists with scarring
- Overall skin quality: Hydration, pore appearance, and general skin quality improvements are a consistent side benefit of PRP beyond the scar-specific goal
What PRP Will Not Do
- Complete elimination of established scars — this is rarely achievable with any single treatment modality
- Meaningful improvement of deep ice-pick scars — these require a different treatment approach
- Fast results — PRP requires patience. The treatment is working during the weeks where nothing visible is happening
- Replace active acne management — PRP treats the damage from past acne but will not prevent new breakouts. Active acne should be medically managed before starting a PRP course
Important before booking
Active, ongoing acne should be cleared or brought under control before beginning PRP. Treating active acne alongside healing scar tissue creates a counterproductive cycle. Your doctor at Casablanca will confirm your skin is at the right stage before proceeding — this is standard medical practice, not a delay tactic.
Frequently Asked Questions
Does PRP work for acne scars?
PRP can significantly improve certain types of acne scars, particularly rolling scars and shallow boxcar scars, by stimulating collagen remodelling. It is less effective for deep ice-pick scars and does not work on raised or keloid scars. Results build progressively over a course of 3–4 sessions and continue improving for several months after the final session.
How many PRP sessions are needed for acne scars?
For acne scars, a minimum course of 3–4 sessions spaced 4 weeks apart is typically recommended. Scar improvement from PRP is cumulative — each session builds on the collagen remodelling from the previous one. Most clients see meaningful visible improvement by week 8–12, with the full extent of results assessable at the 3–4 month mark after completing the course.
What types of acne scars respond best to PRP?
PRP microneedling works best for rolling scars and shallow boxcar scars. It is less effective for deep ice-pick scars and is not suitable for hypertrophic or keloid scars. Your doctor will assess your scar type at consultation to confirm whether PRP is the most appropriate treatment for your specific pattern.
How long does it take to see results from PRP for acne scars?
Initial texture improvement is usually noticeable at 4–6 weeks after the first session. More meaningful scar improvement is typically visible at the 8–12 week mark. Full results from a 3–4 session course are best assessed 3–4 months after the final session, as collagen remodelling continues after treatment ends.
Is PRP better than laser for acne scars?
PRP and laser address acne scars through different mechanisms and are often used together. Ablative laser produces faster scar improvement but comes with significant downtime. PRP achieves more gradual improvement with minimal downtime. For darker Malaysian skin tones, PRP carries lower pigmentation risk than ablative laser — making it a preferred starting point for many clients.
Can PRP remove acne scars completely?
PRP significantly improves the appearance of suitable acne scars but rarely removes them completely. Rolling scars and shallow boxcar scars can see 30–60% improvement over a full course, with skin texture becoming noticeably smoother and scars less visible in most lighting. Complete elimination of established scars typically requires a combination approach over time.
