If you're trying to strengthen your nails or grow out your hair, at least one person in your life will inevitably recommend that you start taking a biotin supplement or smooth on an infusion. But what exactly is biotin and why is it the most popular go-to for hair, skin and nail repair? Biotin is a B complex vitamin sometimes referred to as coenzyme R, vitamin B7 or vitamin H. It's found naturally in nuts, soybeans, eggs, avocado, cauliflower, berries, fish and mushrooms, and contributes to a healthy metabolic, nerve, digestive and cardiovascular functions.

When ingested, biotin converts nutrients into energy that our body uses to complete physical activities and robust psychological functioning. It promotes longer and stronger hair, skin and nails by strengthening hair follicles and cells. When applied topically, biotin penetrates into hair and skin to protect and strengthen, allowing growth cycles to reach their full growth cycle before breaking. That's why you notice a difference in your ponytail or manicure with regular use; biotin has empowered them to grow longer without losing structural integrity. Dermstore's collection of biotin products will help you get the look you've always deserved.
