This is a Beyond Beauty product which means it has been sourced, tried and tested and finally declared one of the most new and innovative heroes out there. Sunday Riley's Good Genes features clean, purified glycolic acid that deeply exfoliates and repairs the look of dull, congested, and sun damaged skin for a visibly radiant, healthier-looking complexion. Containing clean, ultra-pure, formaldehyde-free glycolic acid, to revitalize the appearance of dull, congested, and sun damaged skin, without compromising on what matters to you most: safety, quality, and fast results. Good Genes Glycolic penetrates the surface of the skin with tiny glycolic acid molecules, sinking deeper into the skin than other forms of AHA, to break apart pore-clogging debris and repair the look of sun-damaged, congested, wrinkled, or dull skin. With just one use, instant radiance and skin clarity are visibly boosted. Balanced with fermented prickly pear extract, perfect for sensitive skin, to soothe and calm the complexion, along with skin-purifying lemongrass extract.£233.33 per 100.00ml
