Collagen is a protein found in the body. Over time, as you age your natural collage breaks down causing your skin to weaken and lose it elasticity. Due to this loss of collagen your skin starts to show wrinkles and lines. Collagen injections become helpful filling and smoothing your skin, giving you that younger fresher look. These injections replenish the natural collagen by using the cells found in either humans or cows. Collagen will last about 6 months before you need to have the procedure done again.
