RETINOL

The A* student of the skin care league, retinol is much more than a formidable line-lessening powerhouse (though it certainly helps to press 'pause' on the signs of time passing). By encouraging cellular turnover, retinol helps to reduce pigmentation, scarring, blemishes... you name it! With so many strings to its impressive bow, it's a skin care game-changer but, proceed with caution: introduce it gradually to build up tolerance to reap the rewards without redness.
