Our eyelashes grow at a 4 to 8 week cycle. It is important that the hair follicle anagen growth phase lasts long enough to ensure the best and strongest lashes. Otherwise they could grow more slowly, weaker, and thinner. Thinning lashes is often genetic and more frequent as we grow older. Hormonal and autoimmune conditions can also be responsible. But there are steps that you can take for healthy lashes that look better and longer. Just like the rest of our body eyelashes need vitamins and nourishment to keep them strong and healthy. This serum targets the lash hairs and follicles during the anagen phase providing not only antioxidants and vitamins but a new proven peptide to help stimulate lashes to grow thicker and longer and look really gorgeous.
