Laser Treatments
Laser therapy is one of the more effective treatments for acne scars, but choosing the right laser (especially for darker skin tones) is crucial to avoid complications.
The Best and Worst Lasers for Acne Scar Repair in Dark-skinned People: How to Select a Laser That Won't Cause Dark Spots (Hyperpigmentation)
Choose wisely. The 1550 nm Erbium laser may be the least likely to cause hyperpigmentation, while the 1450 nm Diode laser may be the most likely to do so.
Does Laser Treatment for Acne Scars Cause Dark Marks on the Skin (Hyperpigmentation)?
A small risk. About 5% of people who get laser scar treatment develop temporary hyperpigmentation.
Microneedling
Microneedling creates controlled micro-injuries to stimulate collagen production and improve the appearance of indented scars.
Microneedling and Acne Scars
Can help, but not for active acne. Microneedling may improve indented acne scars. But warning: never try microneedling on active acne.
Chemical Treatments
Chemical peels use acids to resurface the skin and promote collagen production, helping to reduce the appearance of scars.
How Trichloroacetic Acid (TCA) Reduces Acne Scars (and May Also Help with Acne)
Dual benefits. Trichloroacetic acid reduces scars by promoting the production of collagen (and may help acne by exfoliating the skin).
Body Scars
Acne scars on the body present unique challenges but can be treated with many of the same approaches used for facial scars.
How to Treat Acne Scars on the Body
Same treatments apply. Acne scars on the body tend to be fewer but more severe. Treatment is the same as for scars on the face.
What to Avoid
Some popular skincare products and treatments can actually do more harm than good for acne-prone skin.
Why Facial Scrubs Are Not a Good Choice for Acne-Prone Skin
Skip the scrubs. Facial scrubs do more harm than good by physically irritating the skin.
