Do as we say and not as we did, here – and read our lips: Just. One. Drop. Because that’s all you need of Tan Luxe Sleep Oil to keep an incredibly realistic summertime glow going for many months to come.

Don’t do what Jo did, and use it generously, like a regular facial oil on her fairly pale complexion. The results were not so much ‘healthy’ as ‘Trump-esque’. (Enzyme masks and some in-depth exfoliation got it back to normal – but it was paper-bag-over-the-head couple of days.)

She decided to give this another go, though – and was delighted with the results. First, we recommend moisturising, then smoothing a single drop – from the palm of the hand – over the top, blending well at the edges. Although it features raspberry seed, kendi, marula, jojoba and apricot oils, vitamin E and aloe vera, you’ll get much better results if you rely on another product for actual moisturisation.

And then it’s a great way to hang onto summer – one drop at a time.
