Chemical peels are used to treat different skin problems such as acne, sun spots, fine lines, wrinkles, and uneven skin tone and texture. They involve the use of chemicals such as glycolic acid, salicylic acid, Jessner's solution, trichloroacetic acid (TCA) and phenol.
The chemical is applied to your skin and then removed after some time. The top layer of your skin peels off as a result, revealing newer, more youthful-looking skin. TCA and Jessner peels are two popular types of chemical peels.
TCA peels are available in different strengths or concentrations. The stronger the solution is, the deeper it penetrates the different layers of your skin. Superficial peels are done with 10 to 20 percent and 25 to 35 percent TCA; medium-depth peels are done with 40 to 50 percent TCA, and a deep peel results from the use of greater than 50 percent TCA. According to "The Color Atlas of Chemical Peels," the use of TCA with a concentration above 35 percent gives unpredictable results such as scarring. The book "Aesthetics and Cosmetic Surgery for Darker Skin Types" states that TCAs at concentrations of 50 percent have been discontinued because it puts dark-skinned patients at risk for hypopigmentation, hyperpigmentation, and scarring.
Jessner's solution is available in one strength only, but the depth to which it penetrates your skin can be increased by applying several layers of the solution during a Jessner peel

A Jessner peel, according to the book "Aesthetics and Cosmetic Surgery for Darker Skin Types," is a superficial peel that is used to treat photoaging, age spots, acne, post-inflammatory hyperpigmentation, melasma and freckles. Jessner peels should not be used on pregnant women or people who are allergic to any of its components.
TCA peels are used for superficial- or medium-depth peels and can treat moderate photoaging, actinic keratosis, blotchy hyperpigmentation, melasma, mild to medium rhytides and superficial acne scars. The best are TCA peels with low strength for excellent results. Some skin and TCA peels

According to "The Color Atlas of Chemical Peels," a Jessner peel has minimal side effects. However, its resorcinol and salicylic acid components have the potential to cause thyroid disease and salicylism, respectively. Some symptoms of salicylism are ringing in the ears, dizziness, confusion or disorientation. However, there have been no reported cases of salicylism, according to "Aesthetics and Cosmetic Surgery for Darker Skin Types."
Some complications of TCA peels are bacterial, viral or fungal infections, skin scarring, acne and change in your skin's texture.
