Can you use Signal Peptides & Matrixyl during pregnancy?
⚠️Medical Deferral Notice
Generally permitted for anti-aging maintenance while pausing topical retinoids. Cosmetic classifications are formulation flags to discuss with your healthcare provider, not medical clearance.
Clinical Summary
Short chains of amino acids that signal skin cells to synthesize collagen and elastin without systemic effects.
Pharmacological Mechanism & Teratogenic Context
Synthetic oligopeptides act locally at cell membrane surface receptors in the epidermis. Because of their molecular size and rapid degradation by cutaneous proteases into natural amino acids, systemic bioavailability is negligible.
