Collagen peptides

Several studies have represented the lucrative aspects of collagen-peptide ingestion on skin photoaging. Photoaging is the aging process that is due to solar radiation.
Oral administration of collagen has protective effects, including improving facial skin elasticity, reducing skin dryness and wrinkles, and increasing the level of collagen on the skin dermis.
The coolest thing is that these benefits have been demonstrated by clinical trials which basically means collagen proteins really work.
