This new serum's formula contains key actives that work in synergy to build on each other's properties for advanced results. The clinically proven solution signals the skin to renew and re-energise what time & environmental damage has depleted. Re-energise your complexion with the RESIST Triple Active Total Repair Serum (30ml), restoring the appearance of firmness and pigmentation. The formula's 0.3% retinyl propionate (a vitamin A derivative with similar benefits to a classic retinol) works to lessen the look of fine lines and wrinkles while refining pores. Niacinamide works further to even out the skin tone and brighten dullness, and 0.4% hexylresorcinol (an antioxidant) preserves the skin's firmness and fades dark spots.
