Most acne scars do not go away completely on their own, but many can be significantly reduced with the right treatment. The key distinction is between temporary post-acne marks — flat discoloration left after a breakout — and true structural scars, which involve changes to the skin’s texture and depth. Individual results vary, and complete removal is not guaranteed. Below, we answer the most common questions about acne scars so you know exactly what to expect and what your options are.
Do acne scars fade on their own over time?
Some post-acne marks fade on their own within a few months, but true acne scars rarely disappear without treatment. The difference comes down to what is actually happening beneath the skin. Red or brown spots left after a breakout are surface-level discoloration, not structural damage, and the skin can gradually clear them. Actual scars involve changes to the skin’s texture and deeper tissue that the body cannot fully repair on its own.
Post-inflammatory hyperpigmentation (PIH) is the flat, darkened skin that lingers after acne heals. For many people, these marks lighten noticeably over six to twelve months with consistent sun protection and a good skincare routine. However, atrophic scars (the sunken, pitted kind) and raised hypertrophic scars involve real changes to the skin’s collagen structure. Without targeted treatment, these tend to remain stable rather than improve. For a broader overview, see our guide to ways to treat acne scars.
Sun exposure is one of the most common reasons post-acne marks take longer to fade. UV rays stimulate melanin production, which can deepen discoloration and make existing marks more visible. Wearing SPF daily is one of the simplest things you can do to support your skin’s natural healing process.
What are the different types of acne scars?
Acne scars fall into two main categories: atrophic scars, which are depressed or sunken into the skin, and hypertrophic or keloid scars, which are raised above the skin’s surface. Scars also vary considerably in depth, which affects how they respond to treatment. Each type forms differently and responds to different approaches, which is why identifying your scar type is an important first step before choosing a treatment plan.
Atrophic scars
Atrophic scars are the most common type and form when the skin loses collagen during the healing process. There are three subtypes. Ice pick scars are narrow, deep, and sharply defined, resembling small puncture marks. Boxcar scars have wider, flat bottoms with defined edges, similar in appearance to a small crater. Rolling scars have soft, sloping edges that create an uneven, wave-like texture across the skin.
Hypertrophic and keloid scars
Hypertrophic scars form when the body overproduces collagen during healing, creating a raised, firm scar that stays within the boundaries of the original wound. Keloid scars are similar but grow beyond the original wound site and can be more challenging to treat. These types are more common on the chest, back, and shoulders than on the face.
What treatments actually work on acne scars?
Professional treatments that stimulate collagen production and remodel the skin’s deeper layers are among the most effective ways to reduce acne scars. No single treatment works for every scar type or depth, and results vary from person to person. Options including RF microneedling and laser skin resurfacing have strong track records for improving scar appearance in appropriate candidates.
RF microneedling for selected acne scars combines the micro-channels created by fine needles with radiofrequency energy, which heats the deeper layers of skin to trigger a collagen rebuilding response. Temporary redness, swelling, and sensitivity are expected after each session. This dual action can improve both texture and overall skin quality over a series of treatments, though individual results vary.
Waterlase laser skin resurfacing uses focused laser energy to remove damaged outer layers of skin while stimulating collagen renewal beneath the surface. It can be a strong option for deeper or more stubborn scarring, though recovery experience differs from person to person and no universal timeline applies.
For post-acne marks and surface discoloration rather than structural scars, Exion Clear RF uses radiofrequency energy to target pigmentation irregularities, improve skin clarity, and smooth mild texture concerns without the recovery associated with deeper treatments.
Which acne scar treatment is right for your scar type?
The best acne scar treatment depends on whether your scars are atrophic, hypertrophic, or primarily discoloration-based, as well as their depth. Matching the treatment to the scar type is what tends to produce the most noticeable improvement. Individual results vary.
- Ice pick and boxcar scars: These deeper, structural scars may respond to RF microneedling or laser resurfacing, both of which work at the collagen level to help rebuild the skin from within.
- Rolling scars: The gradual, wave-like texture of rolling scars may improve with RF microneedling, which can help remodel the fibrous tissue pulling the skin downward.
- Post-inflammatory hyperpigmentation: Flat, discolored marks — distinct from indented scars — respond well to treatments targeting surface pigmentation, such as Exion Clear RF or laser resurfacing for more persistent discoloration.
- Hypertrophic scars: Raised scars may benefit from treatments that remodel collagen, including RF-based therapies, though these can require more sessions and a tailored approach.
A professional consultation is the most reliable way to identify exactly which scar types you have and which treatment protocol may deliver the best outcome for your specific skin. At Ocean Aesthetics and Wellness, we take time during every consultation to assess your skin closely and build a personalized plan around your goals.
How many treatment sessions does it take to see results?
Most people begin to see noticeable improvement in acne scars after two to four professional treatment sessions, with results continuing to develop over several months as collagen remodeling progresses. The exact number of sessions depends on the depth and type of scarring, the treatment used, and how your skin responds. Individual results vary.
For RF microneedling, a standard course typically involves multiple sessions spaced four to six weeks apart. Some improvement may be visible after the first session, but the most meaningful changes often appear as new collagen continues to form in the weeks and months following treatment. The body’s rebuilding process takes time, which is why patience between sessions matters.
Waterlase laser skin resurfacing can produce visible improvement as the skin regenerates, with results continuing to develop in the weeks that follow. Recovery experience differs from person to person, and results are best supported by consistent sun protection and good skincare habits.
For surface-level discoloration, Exion Clear RF tends to show improvement more quickly since it addresses pigmentation at a shallower level rather than rebuilding structural collagen.
