The Facts

• According to the U.S. Food and Drug Administration, glycolic acid is safe for home use in concentrations of 10 percent or less. Chemical peels with a pH of 3.5 or more are safe if formulated with sun protection or packaged with a warning to use sunscreen. Facial washes, toners and creams include glycolic acid as an exfoliating, skin-smoothing ingredient.
  
  

Benefits

• Home chemical peels are cheaper than treatments with doctors or medical spas. There is no recovery period because a home peel only affects the outermost skin cells. In-home kits contain instructions with enough glycolic acid, neutralizing solution and post-peel cream for two or three treatments.
  
  

Risks

• Uneven application of the acid peel solution can cause uneven skin tone. Glycolic acid peels increase sensitivity to sunlight. According to the FDA, chemical peels can cause chemical burns, rashes and blisters.
  
  

Warning

• Glycolic acid peels with acid concentrations greater than 10 percent increase the risk of injury and disfiguring, post-peel hyperpigmentation.
  
  

Alternatives

• Consider blending your own rejuvenating facial with purchases from the health-food store. Sour cream, grapefruit, lemons and pineapple juice contain mild acids that improve your skin's appearance with regular use.
