Vitamin C is without doubt one of the few skincare substances with a ton of impartial analysis to again up its properties, like its brightening and anti-wrinkle advantages. These of you who’re vitamin C fanatics might have observed that with some vitamin C serums, you find yourself with barely stained orange-brown pores and skin after a couple of days of use – type of like faux tan. I’ve typically puzzled why however didn’t actually dig into it previous a fast Google search (which discovered nothing), so I simply put it off as a bizarre aspect impact of vitamin C oxidising.

However lately, I got here throughout a diagram in a peer-reviewed paper on a totally totally different subject that by chance instructed me precisely why vitamin C does this: ascorbic acid ultimately oxidises to erythrulose!

It turns into quite a lot of issues, however for our functions right here, we solely care concerning the truth it turns into 2,3-diketogulonic acid, which then turns into erythrulose, in keeping with the reactions I’ve drawn beneath:

Erythrulose is an ingredient in faux tans, and is commonly included alongside the extra generally discovered dihydroxyacetone or DHA. These substances react with proteins within the lifeless stratum corneum layer of your pores and skin to supply brown compounds referred to as melanoidins that keep in your pores and skin till the lifeless cells come off (after round every week). The response is a Maillard response, just like the reactions that occur when meat and baked items flip brown with warmth.

Erythrulose is notable for giving a barely redder tan than DHA that stains extra slowly, much less streakily and lasts longer. It’s included in tans from St Tropez, Bondi Sands, Jergens, Dove and Fashions Desire which have DHA as the primary ingredient. It’s additionally the only real ingredient in Deciem’s Hand Chemistry Glow Oil and Hylamide Glow Radiance Booster.
