Fortified with a high concentration of pure retinol, Neutrogena’s Retinol Boost+ Intense Night Serum is a fast-absorbing formula that visibly softens fine lines, uneven tone and textural irregularities. Applied before bed, the vitamin A-rich serum works while you sleep to renew the look of the skin and support a stimulating effect. Dullness and discolouration are notably diminished and the complexion appears smoother, firmer and more supple with continued use.
