A series of treatments is often required to maximize the benefits of chemical peels, especially since skin may feel dry or flaky for a few days afterward. For reducing dark circles, very mild, superficial peels are typically used, necessitating multiple sessions. Chemical peels are classified into three types—superficial, medium, and deep—based on their penetration depth into the skin.

Superficial peels utilize mild acids, such as glycolic acid, to target the epidermis, effectively improving skin texture and hydration with minimal recovery time. They also address concerns like dull skin, minor textural issues, fine lines, uneven skin tone, and acne healing.

Medium-depth peels penetrate the upper dermis, using trichloroacetic acid (TCA) to address moderate skin issues while requiring several days for recovery. These peels effectively target concerns such as moderate wrinkles, sun damage, acne scarring, uneven skin tone, and improved skin texture.

Deep peels reach the mid to lower dermis, using agents like phenol to address severe skin concerns while offering dramatic improvements that require extensive post-treatment care. These peels effectively target issues such as deep wrinkles, significant sun damage, severe acne scarring, pronounced uneven skin tone, and overall skin laxity.
