Men and women start to notice their lips thinning around their early 30’s and into their 40’s. This is also the same age that the body’s metabolism is starting to slow down, and our bodies begin to expand and fill out while our lips begin to lose there is voluptuous volume. The main reason our lips thin as we get older is due to the depletion of natural collagen being produced. Once we reach our 20s our natural collagen production starts to decrease about 1% to 2% each year. Natural collagen production is crucial as it adds structure to the skin and creates a base for the natural elasticity and hyaluronic acid that is produced by our bodies which are vital for our faces structure, Shape, and suppleness of the lips.
