@thecellbrief: Flip your face cream over. See "peptide" in the ingredients? 🧴🧬 Skincare peptides come in 4 families: ✨ Signal: a 5-amino-acid scrap of collagen that, in a lab dish, told cells to make more collagen ✨ Carrier: a tiny 3-amino-acid peptide that carries copper, a helper for collagen building ✨ Nerve signal: designed to quiet the "move" signal from nerves to muscles ✨ Enzyme inhibitor: meant to slow the enzymes that break collagen down How to spot them: "peptide" hides inside a long ingredient name. Tri = 3 amino acids, penta = 5, hexa = 6 🔍 In one 12-week study run by scientists at a big skincare company, 93 women used a peptide cream on one side of the face and the same cream without it on the other. The researchers measured fine lines with image analysis. Which family is in your cream? 👇 Education only. Not medical advice. #Science #biology #skincare #ScienceExplained #learnontiktok
