Injectable skin fillers such as collagen have expanded the field of cosmetic dermatology, allowing new forms of facial rejuvenation, wound healing, and scar repair without surgery. Collagen injections are commonly used to increase tissue volume, reduce wrinkles, and improve the look of skin overall.
Collagen is a natural protein in the human body that supports the joints, bones, ligaments, and skin. Injectable collagen is commonly derived from cows, and as a result, a small percentage of people are allergic to the treatment. A doctor who provides collagen treatments should perform a skin test prior to treatment to determine if a patient will have an adverse reaction. There are newer types of collagen treatment, making use of human collagen, reducing the potential for allergic reaction.
