Exfoliation is the process of removing the topmost layer of dead skin cells. This can be achieved chemically, by applying an acid that dissolves those cells, or mechanically, by using a brush or scrub to physically remove the cells.
Dr. Lupo says results are immediate after an exfoliation treatment, as the removal of dead cells leaves the skin looking brighter. Exfoliation also can improve the effectiveness of topical skin treatments, which can penetrate deeper once the topmost layer of skin is removed. Long-term benefits of exfoliation can include increased collagen production, resulting in younger-looking skin.
According to Dr. Lupo, individuals who may benefit from exfoliation treatment include those who have experienced premature aging due to sun exposure and those with noninflammatory acne, which is acne with only blackheads and whiteheads.
Proceed With Caution
On the other hand, Dr. Lupo says, individuals with inflammatory acne, which includes cysts and pustules, should consult a board-certified dermatologist before selecting an exfoliation method. More aggressive chemical or mechanical treatments could actually make their condition worse. The same is true of people with rosacea, as many forms of exfoliation may increase facial redness.
