Dr Mercola Dr Mercola Hair, Skin and Nails (Biotin, Keratin & Hyaluronic Acid) | 30 Capsules

The 3 special clinically-proven ingredients that work from within to significantly improve the appearance of your hair, skin and nails are:

• Biotin (also known as vitamin H or B7) is considered the “Beauty Vitamin” for the role it plays in maintaining the infrastructure of keratin, one of the crucial structural proteins for healthy skin, hair and nails.
  
  Biotin was originally recognized for its effectiveness in treating hoof issues in horses and cattle. Those findings led researchers to explore whether biotin might offer help for strengthening brittle fingernails in humans.
  
  
• Solubilized Keratin, extracted from premium quality pure New Zealand wool using a unique patented process, is a natural bioactive keratin (unlike denaturalized or hydrolysed keratin that’s widely used in hair and skin care products) to help maintain healthy hair growth, skin elasticity and strong nails.
  
  It’s the main protein in your skin and makes up its surface layer – the epidermis. Keratin is what makes your skin rigid and plays a key role in barrier protection.
  

  This protein has one of the highest proportions of cysteine, an amino acid that acts as an important antioxidant and a natural reservoir of sulphur. Much of keratin’s structural strength comes from cysteine.

  Keratin is also responsible for most of the structure of your hair and nails. When beauty professionals apply keratin treatments to hair, skin and nails to provide protection or to repair damage, they use extracted keratin.

• Low Density Hyaluronic Acid (HA) is a special form of highly bioactive HA that provides natural support for your skin’s hydration, helping to keep it youthful looking and radiant and smooth to the touch.
  
  HA is a critical part of your skin, providing natural support for the dermis – the “plump” second layer of your skin. It helps deliver nutrients and keeps your dermis layer moist by pulling water from other areas of your body.
  By keeping your skin moist, HA makes it stronger, smoother and tighter. This is just one reason why hyaluronic acid is so popular in many skincare products.
