It's a peptide your body already produces — studied since 1973, with a deep base of published research documenting what it does at the cellular level: it signals the cells responsible for collagen and elastin production to increase output. More collagen means denser, firmer-feeling skin. More elastin means skin that stays tight instead of going soft. Natural levels decline as you age; topical application is how you put it back to work. Absorbs fast. No residue. Builds the longer you use it.\u003c\/p\u003e\n\u003ch3\u003eWhat it does\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBoosts collagen\u003c\/strong\u003e — visibly firms skin and supports elasticity\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAccelerates repair\u003c\/strong\u003e — helps skin recover from blemish marks and environmental damage\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eReduces redness\u003c\/strong\u003e — calms and evens tone\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDeep hydration\u003c\/strong\u003e — sodium hyaluronate locks in moisture immediately\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSmooths texture\u003c\/strong\u003e — refines the skin surface for an even finish\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEnhances radiance\u003c\/strong\u003e — restores a healthy, awake look\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eHow to use\u003c\/h3\u003e\n\u003cp\u003e\u003cstrong\u003e1.
