Trichloroacetic acid peel, also known as a TCA peel, is a medium-strength peel that can diminish fine lines, wrinkles, age marks and acne scarring. The peel also stimulates collagen production and skin elasticity. The side effects of this treatment are peeling, flaking, swelling, redness, irritation and inflammation. Consult with a skin-care professional prior to applying the peel. TCA peels should be customized by a professional to fit a person’s skin type, sensitivity level and medical history. Prior to applying the TCA peel, you will need to dilute the acid unless you have purchased TCA that was pre-diluted.

Things You'll Need

Consult with a professional to find out what percentage of TCA peel is right for your skin type.

Examine the label on your bottle of TCA. To achieve the desired solution, you need to know what percentage of TCA you are starting with.

Put on your protective gloves.

Dilute the product by mixing purified water with the 100 percent TCA. For a 50 percent mixture, combine one part 100 percent TCA and one part water. For a 25 percent solution, combine one part 50 percent TCA and one part water. For a 12 percent solution, combine one part 25 percent TCA with one part water. If you need a mixture that is weaker than 12 percent, simply add more water.
