My Best Friend Has Incredible Skin—This Is the £15 Foundation She Swears By

I've known my best friend, Lotte Williams (ASOS Insider and all-around wonderful human), for over 11 years now. That's 11 years of sharing outfits, gossip and skincare tips. But it wasn't until recently that I discovered the £15 product that she swears by. From the image below, you can clearly see Lotte has amazing skin. She's blessed with great genes, but she also struggles with breakouts like the rest of us. However, it's this one product that she turns to time and time again to give her a dewy, even complexion. The product in question? No7's Stay Perfect Foundation.
