NIACINAMIDE

‘Niacinamide is a form of vitamin B that helps tackle fine lines and uneven skin tone,’ says Dr Bunting. ‘It’s a really useful ingredient as it’s very well tolerated and improves tolerance of retinol-based products, too.’ Eltamd Skincare Renew Eye Gel (£37.50 for 15ml) is a multitasking formula with niacinamide, vitamin C and hyaluronic acid, while La Roche-posay Toleriane Ultra Eye Contour (£15 for 20ml) is specifically designed for sensitive skin and contains niacinamide along with effective moisturisers, including glycerine, squalene and shea butter.
