Ceramides vs Peptides
Two popular actives, side by side — no fluff.
Ceramides
aka ceramide NP, ceramide AP, ceramide EOP
Ceramides are lipids that make up roughly 50% of the skin barrier. They're not glamorous, rarely trend on social media, and don't promise overnight transformation — which is exactly why they work. Consistent use demonstrably improves barrier function, moisture retention, and skin resilience.
Peptides
aka copper peptides, matrixyl, palmitoyl tripeptide
Peptides are short chains of amino acids that can signal skin cells to produce more collagen and elastin. The category is broad and evidence quality varies dramatically — some peptides (like Matrixyl) have decent clinical data, while many others are supported by little more than in vitro studies and marketing enthusiasm.

Can I Use Them Together?
Yes, they can be used together
Ceramides and Peptides have no known negative interactions. They can be layered in the same routine safely.
