Collagen is a protein found in bones, tendons and skin. Collagen keeps skin strong and elastic. However, as you age, collagen loses its strength and starts to wrinkle and sag. You can recognize collagen loss in smile lines, sagging chins and wrinkled foreheads. Many people deem these qualities as unattractive and look for ways to regenerate collagen. There are several ways to do that and regain your youthful appearance.

Get Restylane, a wrinkle-filler injection. According to Reuters, Restylane, a temporary filler for wrinkles, makes skin produce more collagen. Ask your doctor about getting Restylane fillers. Fillers may or may not be covered by your insurance, so call your carrier to find out if you have to pay for the injections.

Get pure Vitamin A or retinol. Vitamin A regenerates collagen, according to Skin Library. However, Vitamin A that you buy over the counter may not be as strong as the kind you can get from a pharmacist. For the strongest effect, ask your doctor to give you a Vitamin A skin product at prescription strength of .15 percent to 1 percent. Be careful not to be too aggressive in your treatment. Putting on too much Vitamin A cream at one time can cause irritation.

Get an anti-aging procedure done. Anti-aging procedures will heat the dermis to produce more collagen. For instance, the Thermage skin-tightening procedure works by heating the dermal layer to cause a contraction, according to the Locateadoc website. The heat triggers collagen production. Ask your doctor about an anti-aging procedure that will heat the dermis such as Thermage, laser photo rejuvenation or laser skin resurfacing.
