Doctors use lasers and retinoic acid to treat skin damage. Scientists have now uncovered a common mechanism that links both, paving the way for new treatments.
Skin damage, in the form of dark spots and wrinkles, naturally occurs as we age. Ultraviolet light from the sun is a major factor in skin aging and causes what experts call photoaging.
Cosmetic procedures, such as laser treatment, chemical peels, and microdermabrasion, can reduce some of the signs doctors associate with photoaging.
