Men and women do a lot to keep their skin looking youthful, glowing and clear. From cleansers to moisturizers to retinol treatments, there’s pretty much nothing that people won’t try doing to achieve a flawless complexion. But would you shell out almost $500 for a DNA test to determine exactly which products your skin needs?

According to the London Evening Standard, one English beauty salon has developed a 30-minute saliva test that uses gene technology to determine which active ingredients in skin products would be most beneficial to your skin. This knowledge would allow you to customize a skincare regimen that addresses all of your complexion’s needs, most likely leaving you with encouraging results.

It’s a lot of money, but it may be worth it to see exactly what your skin craves as far as products are concerned. The developer of the test has plans to launch it globally next year, so until then you’ll have to continue to experiment to determine which skincare products are best for your skin type and lifestyle.

Luckily, there are plenty of collections and lines that cater to multiple skin types, so you can see results no matter how oily, dry or sensitive your complexion may be. Dermalogica is just one example of a company that has products for every kind of skin.
