The One Product Dermatologists Wish Everyone Would Start Using

I've always been into my skincare. (Ask any girl with hormonal acne and I'm sure she'll tell you the same.) The desire to find that one wonder product started in my teenage years, where I'd spend hours lusting over the just-launched cleansers and shiny posts of moisturisers in the monthly glossies, while most weekends involved poring over the shelves in Boots deciding how to spend the £30 I'd earned from my Saturday job. (Which, for the record, actually happened to be in Boots.) Since then, I've been lucky enough to try some of the best skincare products on the market and have created a routine that works for my skin and its needs. But I'm ashamed to say that my routine was distinctly lacking in one skincare product until about a year ago: SPF.
