Acne and post-acne marks on the face can be treated with laser therapy. Acne and its residual marks may result from excessive sebaceous gland secretion, leading to infection by *Propionibacterium acnes*. Laser treatment delivers intense photothermal energy in a fraction of a second, which helps eliminate inflammatory infection, suppress sebaceous gland activity, and stimulate the regeneration and reorganization of subcutaneous collagen and elastin fibers—thereby effectively reducing acne lesions and post-acne marks.
