Tan on the wane...? Exfoliation helps keep it bright.  But as well as scrub-a-dub-dubbing, we're rather taken with this oil, which adds a silky veil of argan-enriched bronzitude to post-summer skin.  (There we go:  that ingredient again...)

Douvall's Argan Bronzing Oil is especially good on fading forearms, we've found.  (Though do give it a few minutes to sink in if you're wearing white or getting back into bed, because unlike some instant tans, it doesn't 'set' immediately - 'cos it's an oil, duh...)

But the combination's lovely and super-realistic:  oil and mineral make-up pigments, effectively delivering the sun-kisssed glow.  Might be too much faff for a whole body, but exposed shins or forearms that are becoming a bit pastier than you'd like?  Perfect.

The small dropper bottle's probably all you need at this time of year, for tan top-ups, but there's a bigger version, too, for holidays (or when summer swings round again).  If you want to try-before-you-buy, it's at Urban Retreat at Harrods, which is always worth a beauty-mooch.

Douvall's is an organic, ethically-produced range from Alicia Douvall, a vegan, world-travelling mother, actress and model, who - like us - first stumbled upon argan's powers while in Morocco.  But despite the fact it's the ingredient du jour, we're huge fans of argan - and pleased to find this innovative way to apply it.

Because we're really, really not ready for the sun to set on summer, just yet.
