Starring 5% nature-derived glycolic acid (it comes from sugar cane), the Liquid Gold Exfoliating Treatment (30ml) with 5% Glycolic Acid harnesses the cell-stimulating and exfoliating properties of alpha hydroxy acids, which melt the 'glue' that binds dulling dead cells to skin's surface, revealing the healthy 'new' skin cells beneath. Now in a 30ml travel-friendly size, you never have to be without this skin-clearing champion. What's more, by lowering skin's pH (from 5.5 to around 3), this overnight treatment stimulates cellular activity — accelerating the repair and renewal processes, as skin works hard to re-establish equilibrium. It bolsters synthesis of elastin and collagen (the 'scaffolding' that keeps skin firm), while penetrating deep within pores to eradicate spot-causing bacteria, all while the resurfacing action helps to diminish visibility of post-blemish scars, dark spots and brown patches, so your complexion quickly looks more even-toned and luminous. It's a must-have for anyone concerned with premature skin ageing, sun damage or problem skin conditions — just build up skin's tolerance gradually (to minimise redness). Apply with a dampened cotton pad, once a week for 2–3 weeks while skin acclimatises, then build up to 3 'neat' applications a week for maximum skin-brightening benefit.
