Common questions

Are topical peptides safe?

Cosmetic peptides are widely used in skincare. As with any product, patch-test first and consult a professional if you have sensitive skin or concerns.

Are these the same as injectable peptides?

No. Topical cosmetic peptides are applied to the skin and sold as beauty products. Injectable "research" peptides are an entirely different, medical category — see our educational research page.
