Expert Verdict
Peptides are generally well-tolerated with low allergenicity; the lipophilic modification aids penetration but may warrant patch testing in sensitive formulations. The isooctanoyl chain enhances skin penetration and bioavailability of the tetrapeptide; peptides signal endogenous skin repair mechanisms and are frequently used in anti-aging cosmetics
