The Beauty of Keratin
Long an ingredient in topical products, keratin has become the latest breakthrough nutrient in supplements for hair, skin, and nail health
How keratin has become a key ingredient in supplements for hair, skin, and nails.
Keratin is a protein in our bodies that supports the structure of skin, nails, and hair, but a poor diet or simply getting older leads to lower levels. These show up as dry and wrinkled skin, brittle nails, and more fragile or thinning hair. Keratin has been an ingredient in hair products for many years, and more recently became available in supplements to boost levels— and beauty— from within.
Years of research led to a special process to make keratin absorbable in supplements. This form of keratin, called Cynatine HNS is now found in many beauty formulas, and has been shown to improve the health and appearance of skin, hair, and nails.
To test out the eff ects of keratin on skin, researchers in Salt Lake City, Utah, compared the results of 500 mg daily of a Cynatine HNS keratin supplement with a placebo among a group of 50 women. The study, published in the International Journal of Cosmetic Science, measured skin moisture, elasticity, wrinkling, and overall appearance. After 90 days of daily use, women taking keratin showed signifi cant improvement.
In another study, published in The Scientific World Journal, researchers from the U. S., Canada, and Australia collaborated to test the same keratin supplement for eff ects on hair and nails in a group of 50 women. They measured hair loss, hair growth, hair strength, hair luster, and amino acid composition, as well as nail strength and appearance. Compared to a placebo, keratin produced signifi cant improvements in both hair and nails.
One measure was a hair- pull test, measuring how many hairs were lost on pulling. Among those taking keratin, there was a 16.9 percent improvement after 30 days, 38.9 percent improvement after 60 days, and 46.6 percent improvement after 90 days. Nail characteristics that were tested and showed signifi cant improvements included hard/ soft, resistant/ fragile, broken/ not broken, rough/ smooth, and yellowish/ white. All tests were carried out by licensed dermatologists.
