Frequently asked questions

What do peptides do for skin?
Peptides signal skin to support collagen, helping maintain firmness and elasticity — a gentle anti-aging option.
Peptides or retinol?
Retinol is stronger but can irritate; peptides are gentler and easier to tolerate. Many people use both, at different times.
