Acne scars can feel discouraging, especially when active breakouts have already cleared but the marks they left behind haven't. The good news: while scars are more stubborn than regular dark marks, there are real, evidence-based ways to reduce their appearance — and even better, ways to prevent new ones from forming in the first place.

Scars vs. Dark Marks: An Important Difference

These two are often confused, but they're not the same thing:
  • Dark marks (PIH) — flat, discolored patches that fade on their own over weeks to months (covered in the complete guide to fading dark marks)
  • Acne scars — actual changes in skin texture, either indented (atrophic scars) or raised (hypertrophic/keloid scars), caused by damage to collagen during severe inflammation
The treatment approach for each is different, which is why identifying which one you're dealing with matters before choosing a product or routine.

Types of Acne Scars

  • Ice pick scars — narrow, deep pits, often from severe cystic acne
  • Boxcar scars — wider, shallower depressions with defined edges
  • Rolling scars — broad depressions with a wave-like texture
  • Hypertrophic/keloid scars — raised, thickened tissue (less common on the face, more common on the chest and back)
Most teen acne scarring falls into the atrophic (indented) category, typically resulting from acne that was picked, popped, or left untreated during a severe, inflamed stage.

Step 1: Stop Active Acne First

Treating scars while acne is still active is like renovating a room during an ongoing leak — new scars can form faster than old ones improve. Getting active breakouts under control is the essential first step (see what is the best acne treatment for teens), and it's also the single most effective form of scar prevention.

Step 2: At-Home Options for Mild Scarring

For mild, shallow scarring, some ingredients can help improve texture and appearance over time:
  • Retinoids (adapalene) — boost skin cell turnover and collagen production, gradually softening the appearance of shallow scars
  • Vitamin C — supports collagen synthesis and has antioxidant benefits
  • Niacinamide — supports overall skin barrier health, which aids the skin's natural repair process
  • Chemical exfoliants (AHAs like glycolic acid) — support gentle resurfacing over time
These options require consistent use over several months and work best on mild texture changes — deeper scars typically need more than at-home products can offer.

Step 3: Professional Treatments for Moderate-to-Severe Scarring

For scars that don't respond to at-home care, dermatologists offer several evidence-based options:
  • Microneedling — creates controlled micro-injuries to stimulate collagen production, effective for rolling and boxcar scars
  • Chemical peels — deeper resurfacing than at-home exfoliants, used for various scar types
  • Laser resurfacing — targets scar tissue and stimulates new collagen growth
  • Dermal fillers — temporarily fill in depressed scars for a smoother appearance
  • Subcision — a minor procedure that releases scar tissue bands beneath rolling scars
These treatments generally require multiple sessions and should only be done by a qualified dermatologist, since improper technique can worsen scarring, especially on melanin-rich skin, which can be more prone to pigmentation changes from aggressive procedures.

Why Prevention Matters More Than Cure

Scar treatments — especially professional ones — are more time-consuming, expensive, and gradual than treating active acne early. This is why dermatologists consistently emphasize:
  • Treating inflamed, cystic acne promptly, rather than waiting it out
  • Never picking or popping pimples, especially cystic or deep ones
  • Seeing a dermatologist early for severe acne, since early treatment significantly reduces the risk of permanent scarring
A teen who treats active severe acne early is far less likely to need scar treatment later — making prevention the most effective "treatment" of all.

Setting Realistic Expectations

It's worth being honest: most scar treatments improve the appearance of scarring rather than completely erasing it. Combining consistent at-home care with professional treatment, when needed, offers the best realistic results. Patience is essential here even more than with dark marks — visible improvement in texture-based scarring often takes several months to over a year, depending on severity and treatment type.
