MODEL RELEASED. Laser wrinkle treatment. Woman undergoing laser cosmetic treatment to reduce the appearance of wrinkles. She is wearing goggles to protect her eyes from the laser. The pen-like tool (blue) focuses a pulsed laser beam onto the patient's skin. The laser stimulates the production of more collagen in the upper layers of the skin's epidermis. Collagen is an elastic connective tissue that is present naturally in the skin, but which is not replaced so effectively as people age. Stimulating the production of more collagen reduces the depth of wrinkles.
