Scared of the beauty hall? So was I. Until I wrote a piece – Can you Buy Good Skin? – for October's ELLE about shopping for skincare. I braved department stores and investigated online for my perfect match – but I found my happy ending in a west London lab, and a saliva swab.

It was as strange and scientific as it sounds. Using a fusion of the technology from mobile phones and the science that investigates the effectiveness of pharmaceuticals, GeneOnyx developed a test which matches your DNA to the ingredients which will best suit your skin – and most excitingly, best future proof your skin against ageing.

No longer do you need to gamble with products that might or might not make a difference – this system means you can be sure the ingredient you’re betting on will pay off.

In that piece I wasn't able to tell you how you could get that test yourself – the technology was so new those details hadn’t been released or even decided – but now the secret’s out and I can. You won't have to go near a lab; in fact, all you'll need to do is go to The Organic Pharmacy. There, in the King’s Road store, in 30 minutes, a cheek swab will reveal the ingredients that work for you – and the Organic Pharmacy products that fit the bill for your skin. That test is built into a one-hour consultation, so that your genetic profile can be interpreted by Organic Pharmacy’s experts into an everyday skincare prescription.

But you’ll also be provided with a list of ingredients that suit your skin, so you can DIY your bespoke and find products from other brands with the same seal of approval. The test certainly worked for me. Three months later and I’m still using the prescribed products. Why wouldn’t I when my skin is so much improved and the future of my skin is scientifically safeguarded? But the cost? Almost ?300. So what do you think? Is that a price worth paying for perfect skin?

The Organic Pharmacy DNA Test, ?295 for 60 minutes (consultation including a personalised skincare prescription based on your genetic profile).
