Various over-the-counter remedies can help reduce the appearance of acne scars. Products containing the following ingredients may be useful. However, over-the-counter creams and lotions are unlikely to remove or flatten a raised scar fully.
Salicylic acid
Salicylic acid is a naturally occurring compound used in acne skin care products. Salicylic acid peels help clear dirt, skin cells, and other debris that leads to acne from the skin’s pores.
An older 2010 review suggests using a peeling product containing 30% salicylic acid and applying it three to five times every 3-4 weeks. The authors also note that it is unlikely to cause hyperpigmentation and is, therefore, suitable for use on darker skin.
Salicylic acid also helps reduce swelling and discoloration in the area, which may minimize the appearance of scarring. Salicylic acid can help treat all scar types.
However, people with sensitive skin should do a patch test on a small area of skin before using it on their entire face, as it may cause dryness or irritation.
Retinoids
Some topical retinoids may help get rid of acne scars. As the authors of a 2017 review note, topical retinoids block inflammation, reduce acne lesions, and speed up cell regeneration.
The authors also state that retinoids could help lighten hyperpigmented acne scars, including those in people with darker skin tones.
It is important to note that retinoids can make the skin sensitive to the sun. Anyone using retinoids for acne or scar treatment should wear sunscreen outdoors.
Alpha hydroxy acids
Alpha hydroxy acids (AHAs) can help increase the rate at which skin renews its cells. Some doctors recommend AHAs for treating acne and reducing the appearance of acne scars.
AHAs are a mild form of acid that scrapes away the outer layer of skin to reveal fresh, new skin underneath. This process may help reduce hyperpigmentation due to scarring.
However, swelling, burning, and itching may occur at high concentrations. It is best to speak with a doctor before trying AHAs. They can help identify the best strength to use.
Lactic acid
Lactic acid is a type of AHA. It can act as a gentle peel to pull away dead skin cells. It may help reduce the appearance of scars and smooth the skin.
One review recalls a small study in which seven people with icepick scars had treatment with a product that was 92% lactic acid. There was an improvement of over 75% in one person, 51-75% in three people, 26-50% in two people, and 1-25% in one person.
Lactic acid may also help lighten dark scar tissue, although it can cause hyperpigmentation. Before using products containing lactic acid to treat acne scarring, testing them on a small skin patch is best.
Many products for acne contain lactic acid. It is also present in diluted apple cider vinegar, which makes for a more natural, cost-effective treatment.
Remember, finding the right treatment for your acne scars may require trial and error. If over-the-counter remedies do not provide satisfactory results, consult a dermatologist for further advice. With determination and patience, it is possible to minimize the appearance of acne scars and achieve smoother, healthier-looking skin.
