Like alcohol A, peptides are also a collective name for a large class of substances, but peptides are generally peptides consisting of 2-16 amino acids. The most common ones include copper peptide, hexapeptide, etc.
The functions of peptides are generally to promote collagen production, reduce wrinkles, brighten skin tone, and repair damaged skin. Copper peptide can promote cell growth, protect collagen from degradation, and promote the synthesis of type III collagen. The effective concentration of copper peptide in skin care products is generally 0.2%.
ghk-cu copper peptides for skin
Copper peptide can effectively promote collagen production in fibroblasts treated with GHK-Cu and normal control. The growth outcomes of normal fibroblasts at 48, 72 and 96 hours were measured to be significantly different.
After using copper peptides, facial wrinkles and roughness showed a downward trend, and facial wrinkles improved by 10.82% on days 14 and 28 respectively. and 21.13%, facial roughness is also significantly reduced.
After 28 days of use, 100% of the subjects were satisfied with the improvement in facial hydration, 96.67% were satisfied with the improvement in facial firmness, 96.67% were satisfied with the improvement in facial gloss, and 96.67% were satisfied with the improvement in facial gloss. 96.67% were satisfied with the improvement of facial roughness, 100% were satisfied with the improvement of facial elasticity, 100% were satisfied with the improvement of facial fine lines, and 100% were satisfied with the overall improvement of the face.
copper peptides and vitamin c
Due to the instability of copper ions in copper peptide, copper peptide also becomes easily inactivated and has no effect when paired with many ingredients.
Copper peptides cannot be used with vitamin C and VC derivatives
With the combination of the two ingredients, VC can no longer reduce melanin, and copper ions cannot complex with tripeptide-1, both of which have lost their original effects. It is recommended to use them separately in the morning and evening.
