As we age, collagen will gradually be lost, which cause the collagen peptides and elastic nets that support skin to break, and the skin tissue will be oxidize, atrophy, collapse, and dryness, wrinkles and looseness will happen. Therefore, supplementing collagen peptide is a good way to anti-aging.

The unique skin repair and regeneration of collagen can stimulate the production of new collagen, and then support the skin to moisturize and anti-aging. Studies have showed that eat hydrolyzed collagen peptide and small molecular peptide can achieve the effect of stretch rough lines and tighten skin. It has a good effect on common wrinkles such as nasolabial lines, eyebrow lines, forehead lines, tear groove lines, crow’s feet lines, neck lines.

Color Detection Method

If collagen peptide is light yellow, which means good collagen peptide. If collagen peptide is bright light just like paper, that is, has been bleached. What’s more, we can observe the color after dissolution. Put 3 gram collagen peptide dissolve in 150ml water in a transparent glass, and the temperature is 40℃~60℃. After completely dissolve, take a glass of 100ml pure water, then compare the color between them. The closer to the color of pure water, the better the quality of collagen, and the worse the quality of collagen with darker color. 

Ordor Detection Method

The collagen peptide extracted from marine fish will have slightly fishy, while inferior collagen peptide will be very pungent fishy smell. But there is a situation that fishy odor can’t smell, then additives must be added. Generally, collagen peptide with additives does not smell fishy at first, but it smells fishy and mixed with additives when you smell it carefully.
