No, salicylic acid does not remove true acne scars. As defined by the medical community, acne scarring represents permanent changes in the structure of the skin due to damage to the collagen-producing cells and/or cords of collagen. Rebuilding collagen and/or repairing deep tissue damage (as well as fading the visible signs of post-pimple redness/light-brown discolouration) cannot be accomplished by using salicylic acid. When choosing the appropriate treatment for a condition like this, it is important to identify this difference.
Salicylic acid is classified as a beta-hydroxy acid (BHA) and is effective in penetrating through clogged pores that contain oils, and exfoliating dead cells. While salicylic acid can be used to help control and/or prevent acne and/or similar skin conditions, it has no role in the removal of scars.
What Types of Acne Marks Can Salicylic Acid Improve?
Salicylic acid is effective for post-inflammatory hyperpigmentation (PIH) and post-inflammatory erythema, which appear as dark or red marks after acne heals. These are not true scars but discoloration caused by inflammation. By promoting gentle exfoliation and reducing ongoing inflammation, salicylic acid can gradually improve skin tone and texture.
According to specialists at Redefine Hair Transplant and Plastic Surgery Center, salicylic acid is most effective when acne is still active or when recent acne marks are present. It also helps prevent new breakouts, which reduces the risk of developing additional marks or scars.
Why Can’t Salicylic Acid Treat Deep Acne Scars?
such as ice-pick scars, boxcar scars, and rolling scars—occur in the deeper layers of the skin where collagen has been destroyed. Salicylic acid works only on the surface and within pores; it cannot stimulate sufficient collagen production to repair these structural defects.
Dr Harikiran Chekuri explains that relying solely on topical acids for deep acne scars often leads to frustration and delayed improvement. These scars usually require advanced treatments such as medical peels, microneedling, laser therapy, or combination dermatological procedures for visible and lasting results.
When Should You Consult a Doctor for Acne Scars?
You should consult a skin specialist if acne scars do not improve after 8–12 weeks of topical treatment, if scars are deep or textured, or if pigmentation worsens. Early professional intervention prevents scars from becoming more permanent and difficult to treat. A tailored approach based on scar type is essential for effective results.
