Why they work together: Stimulates Type I, III, and IV collagen Enhances retinol's anti-aging effects Minimal irritation risk Supports skin barrier function Application strategy: Layer together in same routine (peptide first) OR separate AM/PM Signal peptides vs neurotransmitter peptides with retinol Signal peptides (like Matrixyl, Syn-Coll): Best compatibility with retinol Work synergistically Can apply together or separately Neurotransmitter peptides (like Argireline, Leuphasyl): Good compatibility but better separated Different pH requirements may interfere Apply separately (AM vs PM) for best results Peptides to avoid combining with retinol AHA/BHA peptide combinations: Products that combine peptides with acids (glycolic, salicylic) Adding retinol on top = potential over-exfoliation Use peptide+acid products separately from retinol nights High-dose vitamin C + peptides + retinol: All three together may be too much for sensitive skin Vitamin C (L-ascorbic acid) can destabilize retinol Better to separate: Vitamin C AM, Peptides + Retinol PM See our glow peptides guide for complete skincare peptide protocols
Its storage requirements don't conflict with peptide storage
Mark is a rare breed of producer who has exceptional creative instincts and fantastic business acumen, Throop says
Cannabinoids serve as a retrograde signal leading to reduction of glutamate release and, thus, presynaptic expression of LTD
Typical improvements many users see include: Improved hydration and skin plumpness within days to a couple weeks (often due to added hyaluronic acid)
