This gentle exfoliating cleanser is a great option for sensitive skin, as the formula doesn't sit on the skin for a long period of time. The Dermalogica Age Smart Skin Resurfacing Cleanser (£40) combines lactic acid with vitamin E so that the formula won't overdry or irritate your skin as the acid gets to work clearing out clogged pores and breaking down dead skin cells on the surface of your skin. Fans of the cleanser swear it leaves their skin looking brighter, clearer, softer, and smoother with regular use.
