Collagen was the gold standard of injectables for many years. Cosmoplast is a collagen-based injectable filler. Human cell-based collagen, created in a laboratory, this injectable is non-allergenic, allowing for immediate treatments. This material has the benefit of allowing for more superfical injections and therefore very effective for fine lines/ texture. It has local anesthetic within it, and it will last between 3 and 5 months.
