Acne affects people of all ages, and while some studies suggest that retinoids may help improve the appearance of acne scars, results vary based on individual circumstances.

Retinoids can help reduce the appearance of scars by encouraging cell turnover and rebuilding collagen. However, this is usually only the case with shallow scars.

If you have deeper acne scars, a prescription might be necessary. You'll need to speak to a dermatologist who can examine your scars and explain the potential side effects.

Some of the most common side effects of retinol include dryness, irritation, itchiness, and redness. These effects typically subside once your skin gets used to the ingredient.
