2) Acne Scars
Scars from acne are formed by inflammation and damage. Dark spots may develop on your skin and stay for a few weeks. Furthermore, picking your pimples further worsens the skin’s condition and may leave scars that last a lifetime.
Topical retinol products can help reduce the inflammation and edema associated with acne breakouts and can also help prevent new ones. But acne scars that are elevated or sunken may not usually respond well to topical retinol treatment.
