Cosmedix Affirm Antioxidant Firming Serum is a lightweight, multivitamin-rich treatment formulated to visibly firm, brighten and refine skin while defending against environmental stress and premature ageing.

Powered by a comprehensive network of 10 antioxidants, peptides and moisture-supporting botanicals, this fast-absorbing serum targets fine lines, uneven tone, dullness and loss of firmness without leaving skin feeling heavy or overwhelmed. Spin Trap, Superoxide Dismutase, resveratrol, glutathione and vitamin E help counter oxidative stress, while pea and soybean proteins support a smoother, more resilient appearance. Cassia seed polysaccharide replenishes hydration to leave the complexion looking firmer, brighter and more refined with continued use.

Good to Know: Its lightweight, water-based texture layers easily beneath moisturiser and SPF, making it a practical antioxidant treatment for both morning and evening routines.

Product Size: 30ml
