It works by loosening the desmosomes — the protein bonds holding dead corneocytes together — accelerating their shedding and revealing smoother, more evenly toned skin underneath.\u003C\u002Fp>\u003Cp>With regular use it also stimulates modest increases in dermal collagen and glycosaminoglycan content, contributing to a plumper look over time.
