FAQ：

1.What are peptides?

Peptides are short chain molecules formed by amino acids linked together by peptide bonds. They typically consist of 2 to 70 amino acids.

2.What is the role of peptides in skincare products?

Peptides have various functions in skincare products, including:

Moisturizing: Peptides can help the skin retain moisture and increase skin hydration.

Anti-aging: Peptides can stimulate collagen production, reduce wrinkles, and improve skin elasticity.

Whitening:Some peptides can inhibit melanin production and lighten spots.

Repair: Peptides can promote cell metabolism and help repair damaged skin.

3.What do I need to look for when designing phosphorylated peptides?

When designing phosphorylation modifications, the phosphorylation modifications should not be more than 10 amino acids away from the N-terminus to avoid a decrease in coupling efficiency.
