Laser rejuvenation procedures, such as CO2 laser skin resurfacing, YAG (yttrium-aluminum-garnet) laser surgery, and intense pulsed light, can rejuvenate and tighten the skin. There are several types of nonsurgical treatments, used either alone or in combination, that can help tighten skin in a sagging neck and jowl. Botox can be used to diminish the visible bands on the neck, and products that contain skin-firming ingredients, such as niacinamide, hyaluronic acid, and hexamidine, can be helpful in treating milder signs of aging.
Chemical peels and antioxidants can be useful for rejuvenating the look and feel of the skin, improving the appearance of skin discoloration, sun spots and dull skin texture, but they are not as helpful for improving sagging skin. And dermatologists say that collagen products that are applied to the skin will not penetrate and remain as intact collagen.
