Frequently asked
Common questions.
Are peptides as effective as retinol?
No, but they're complementary. Retinol drives turnover; peptides signal collagen production. Use both, alternate nights or layer carefully.
How long until I see peptide results?
Twelve weeks minimum. Peptides are signalling molecules; visible firmness changes lag actual collagen synthesis. Most testers gave up at week 6.
Can I use peptides while pregnant?
Most peptides are pregnancy-safe (unlike retinoids and high-dose vitamin A). Always check the specific formula with your obstetrician, adjacent ingredients may not be.
Do peptides actually penetrate skin?
Topical peptides penetrate to the upper dermis only, they signal rather than rebuild. The marketing claims of 'collagen rebuilding' overstate; the real story is signal-driven gradual improvement.
