The number of layers of cells in the skin actually is reduced. In patients with acne new cells replace the cells of existing pimples and the rapid turnover of cells prevents new pimples from forming. By a similar mechanism Tretinoin can reduce some wrinkles areas of darkened skin and rough areas of skin all of which occur in sun-damaged skin.
