Light Acid Peels The peels in this group, sometimes referred to as "lunch time" peels, are quick, safe and effective. They are characterized by light to moderate penetration, short healing time (some require no healing time at all) and minimal or no discomfort. These peels are excellent at improving the texture of the skin and evening out the skin tone. For maximum results, they can and should be alternated. GLYCOLIC ACID PEEL Glycolic acid is an alpha hydroxy acid derived from sugar cane. It is nontoxic and well tolerated by most people. Glycolic acid peels are usually very superficial peels. However, they need to be neutralized to terminate their action, otherwise, they may penetrate too deep and "overpeel" the skin. Glycolic acid peels exfoliate dead layers of the skin and, typically, require no downtime. They also help reduce acne related conditions by freeing impacted debris from the pores. Although, they won't smooth out acne scars or deep wrinkles, they can improve the texture of the skin. For best results, glycolic acid peels should be performed on a monthly basis. Micropeel is an example of a glycolic acid peel. Created by Biomedic, this peel is combined with cryogenic therapy (dry ice) which helps to kill the bacteria and reduce inflammation associated with acne. It also increases cellular turnover and decreases redness.The Micropeel is available only in medical offices. LACTIC ACID PEEL Lactic acid is an alpha hydroxy acid derived from sour milk. It is ideal for sensitive skin or skin unable to tolerate glycolic acid. Lactic acid peel helps to eliminate germs, toxins and dead cells. It also helps to maintain the skin's pH factor. SALICYLIC ACID PEEL or beta hydroxy peel. Salicylic acid is derived from aspirin. This treatment is particularly helpful in clearing clogged follicles and in promoting exfoliation. I have found it effective primarily on acne skin. Although, it can be used to fade age spots and any pigmented lesions. The peel causes mild to moderate stinging, which peaks at approximately 2 to 3 minutes after its application. Due to its self-neutralizing ability, salicylic acid peel has limited penetration. The level of discomfort may be slightly higher than that of the glycolic acid peel. Salicylic acid can be toxic to the system causing dizziness or headache several hours after the treatment. BEFORE PCA PEEL AFTER PCA PEEL PHYSICIAN'S CHOICE OF ARIZONA PEEL (PCA PEEL) This peel, my favorite among the lighter peels, is especially effective in the treatment of uneven pigmentation and sun damage. It uses a combination consisting of lactic, citric, salicylic and kojic acids, along with hydroquinone. Lactic and citric acids have a lightening effect on the skin. Lactic acid is also very hydrating. Kojic acid and hydroquinone inhibit melanin production, which causes hyperpigmentation. Unlike the glycolic acid peel, this peel is not neutralized or washed off. At most, you may experience a mild stinging sensation along with some redness. To enhance exfoliation, this peel can be combined with resorcinol, a stronger exfoliating agent. For a more dramatic improvement, the PCA peel can be combined with an oxygenating treatment, which enhances the peel's exfoliating properties while increasing blood circulation. The skin is left with a healthy glow and silky smooth texture. ULTRA PEEL   The strongest of the light acid peels, this peel combines lactic acid with a lower concentration of trichloroacetic acid (TCA) to enhance exfoliation. This treatment is ideal for those seeking greater results without the longer healing times associated with stronger acid peels. After 5 to 7 days of mild to moderate flaking (during which you will be able to apply makeup), the skin will be noticeably softer and smoother.
