Concept of peeling (Physical & Chemical) for skin rejuvenation has been around since ancient times. Alpha-hydroxy acids (AHA) was utilized by ancient women to beautify the skin. Sour milk and old wine were among the few ingredients used earlier.
Chemical peeling has been diversified and improved, and become a part of the correction strategy against skin aging, which remains its main indication.
Mode Of Action
Chemical peeling agents are mostly acids that are applied to the skin to remove the outer damaged layers. This accelerates the process of exfoliation. This is followed by regeneration of the skin which is smoother and less wrinkled providing improved appearance. The effect of any peel reaches varying depths, depending on the compound used.
For Which Conditions Chemical Peels Can Be Used?– Acne Scars
– Aging skin
– Fine wrinkling
– Superficial scars and photoaging
Types of Peeling
There are 3 basic types:- Superficial, Medium and Deep
1. Superficial Peeling- This involves only the outer layer of the skin (epidermis and dermal-epidermal interface) for gentle exfoliation. α-hydroxy acids (AHAs), β-hydroxyacids (BHA) such as salicylic acid (SA), all trans retinoic acid, trichloroacetic acid (TCA) and glycolic acid (GA) are used. This type of peeling is used in treatment of acne, mild skin discoloration, to achieve skin radiance, post-inflammatory pigmentation and actinic keratosis.
2. Medium Peeling- This is used for slightly deeper penetration which includes epidermis and upper limit of superficial dermis. Higher percent of TCA is used in this process. Used for mitigating wrinkles, shallow scars and improve skin texture.
3. Deep Peeling- It penetrates deeper in the skin. Used in the treatment of severe photoaging, deep or coarse wrinkles and scars.
Post Procedure Care– Use of sunscreens
– Application of moisturizer
– Use of non-soap cleanser
– In case of crusting, use of topical antibiotic cream is advised
– No facial procedures
Usually minor and preventable.
