Skin's Fountain of Youth
Collagen is the essential component of the dermis layer of skin, however as you age, collagen production slows down. Sadly, after the age of 20, the body produces 1 percent less collagen in the skin every year. As a result, skin becomes thinner and more fragile developing wrinkles as the collagen and elastin connections deteriorate. (1)
Supplementation with collagen has been shown to increase skin flexibility and hydration and reduce the depth of facial wrinkles. In a study among women ages 40 to 60, supplementation with collagen for eight weeks showed a 28% average increase in skin moisture levels, and 91% of subjects reported less dry skin after supplementation.

Research has also shown consumption of collagen supplementation improves skin more effectively than applying topical creams and lotions. Collagen molecules in topical products are too big to be absorbed through the skin into the bloodstream. Studies have shown oral ingestion of collagen peptides is immediately absorbed into the blood and then delivered to skin cells to increase skin-collagen expression. (3.4)

Healthier Hair and Nails
Collagen peptides provide amino acids from which the body can make keratin. In a six-month study focusing on brittle nails, researchers found that daily supplementation with collagen resulted in increased nail growth and improved nail quality in conjunction with a notable decrease in the frequency of broken nails. (1)
The growth and strength of hair follicles is dependent on the collagen matrix in the dermal layer of our skin. In fact, hair follicles produce certain types of collagen in greater amounts than are present in our skin. Without adequate collagen, the total number and thickness of hair follicles can be reduced causing delays in hair cycling and growth. The deterioration of collagen during the aging process may be a significant contributor to hair loss, however recent studies have also shown that supplemental collagen can actually reverse hair loss in some cases.

Reduces Appearance of Cellulite
Adding collagen to your diet helps reduce the appearance of cellulite and stretch marks. When skin loses its elasticity and becomes thin, cellulite becomes more obvious. Collagen increases moisture retention, improves elasticity, and helps smooth out cellulite’s dimpled appearance while minimizing fine lines from stretch marks. Studies demonstrated that a regular ingestion of hydrolyzed collagen over a period of 6 months led to an obvious improvement of the skin appearance in women suffering from moderate cellulite. (5)
