Counts towards your 5 a day. Almost.

I am every Beauty PR’s dream. A true victim of the marketing machinery. As soon as there’s something new on the market, I have to try it, massage it into my skin, rub it, brush it, scrub it.

I have always been a proper sucker for beauty products. Aged 14, when my friends would run off to spend their pocket money on Diesel Saddle jeans (insert extensive cringing here), I put in an extra shift of babysitting to save up for a visit at my favourite perfumery, only to leave it armed with the newest moisturizer, face mask and exfoliator. I still remember the outcome of my first shopping splurge in the beauty department: a Helena Rubinstein mascara (one of the best I ever tried), Jil Sander No.4 Eau de Parfum, a Clinique compact powder, a Helena Rubinstein lipstick, a Dior eye shadow palette, something Chanel-y (I can only remember the packaging, it’s been a while) and a Biotherm moisturizer. Overall damage: 250 Deutschmark. In other words: 50 hours of babysitting.

Throughout the years, I have continued to prefer spending money on beauty products rather than spending them on clothes (or food – I remember eating spaghetti and tomato sauce for weeks on end but not saving a single cent on my moisturizer). Was it worth it? I don’t know. But I even back then, with the peachy skin of a teenager, I wasn’t going to take any chances. Let’s just consider this: the Diesel Saddles will have dissolved by now. Yet I am still wearing the skin I’m in.

Of course I had to say yes to testing the new Biotherm Skin Ergetic concentrate. The older I get, the less I am happy to experiment with products (I know what I want and need after almost two decades of testing). However, I do change the serum I use frequently. You wouldn’t want to take the same vitamins over years either.

I have applied the Biotherm Skin Ergetic concentrate twice daily during the past two weeks. The biggest difference was recognisable after a few days. My skin looked much fresher than it did all winter; a few of my friends asked if I had a tan (I hadn’t, and I wasn’t wearing any makeup). I haven’t seen any further improvement so far, but my skin has kept that sun-kissed glow.

It’s easy to layer with your daily moisturizer as the skin soaks it up pretty quickly. The smell is just gorgeous, like a light and fruity yogurt smoothie. Resist the urge to drink it though.

The concentrate is currently on offer at Boots for £35.
