It’s the season for having a bit of colour, but some dermatologists are still hesitant to recommend self-tanning lotions. One study by the FDA (US Food and Drug Administration) found 11 per cent of DHA (the pigment-producing molecule) goes beyond the surface to reach skin cells in the dermis and epidermis with effects still unknown. The risk of free-radical damage on skin was highlighted by another study. For now, choose a self-tanner without DHA: Tropic Shimmering Body Oil (£28 for 150ml; tropicskincare. com) contains organic coconut oil infused with golden shimmer, while Jurlique Sunless Tanner (£24 for 150ml; jurlique.co.uk) leaves a natural glow.
