SKIN REGENERATION
- The main component of skin is collagen and there are 85-90% collagen type I and 10-15% collagen
type III.
- Collagen fibers that are damaged over time are strongly related to skin aging.
- Skin aging is caused by decreased collagen density and dermal thickness.
- Collagen supplements originating from various sources such as marine, bovine, and porcine can improve skin integrity and modulate skin aging.
- They are effective in wrinkle reduction, skin rejuvenation, and skin aging reversal.
- The effects of oral collagen supplementation on skin hydration and the dermal collagen network were studied
- A randomized, placebo-controlled, blind study of 72 healthy women over 35 years was performed to test the effect of a drinkable nutraceutical collagen product. Half of them (n = 36) received this collagen supplement that is a blend of 2.5 g of collagen peptide, biotin, vitamin C, acerola extract, zinc, and natural vitamin E complex for twelve weeks. Another half of the subjects received a placebo. The test product markedly improved skin hydration, roughness, elasticity, and density of the experiment group compared to the control group
- Asserin et al. investigated the efficacy of oral collagen peptide supplementation on skin hydration in a clinical study. After several weeks of intake, the oral collagen peptide supplementation remarkably increased skin hydration, the collagen density in the dermis remarkably increased and the fragmentation of the dermal collagen network remarkably decreased. These effects persevered after 12 weeks. The results suggested that oral collagen peptide supplementation significantly improved skin aging.
