Peptides vs Squalane
Two popular actives, side by side — no fluff.
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.
Squalane
aka hydrogenated squalene, plant-derived squalane, olive squalane
Squalane is the hydrogenated (stabilized) form of squalene, a lipid naturally produced by your skin. It's one of the most universally tolerated moisturizing oils available — lightweight enough for oily skin, nourishing enough for dry skin, and unlikely to cause breakouts in anyone.

Key Differences
- 1Peptides is a peptide while Squalane is a emollient.
- 2Squalane has stronger clinical evidence (4/5) compared to Peptides (3/5).
- 3Peptides is more hype than substance, Squalane is widely recognized.
- 4Squalane is better suited for sensitive, oily skin.
