Meet the foundation that takes the guesswork out of beauty. Our colour-changing formula adjusts seamlessly to your skin tone, giving you a radiant, natural finish that looks like your skin, only better. It blurs imperfections, softens fine lines and neutralises redness in seconds, all while protecting with SPF 15. One shade, endless confidence. Just apply, blend and watch the transformation.
At first touch the pigments look soft and neutral. As you smooth the formula across your skin, the micro-pigments disperse and warm up, reading the natural blend of tones your complexion needs.
The formula shifts to match your unique warmth and undertone: no guesswork, no harsh lines. Redness is neutralised and imperfections blur into a seamless, second-skin finish.
Lightweight coverage that stays put without settling into fine lines, oxidising or feeling heavy. Just your skin: smoother, more even and protected with SPF 15.

"Going through the menopause I'd struggled to find anything that doesn't dry out during the day. Used to wear Clinique but it feels chalky on my skin nowadays. This one doesn't cling to my dry patches at all. Best I've found so far."

Reverse-ageing Adaptive Foundation
Verified buyer
"I have mature skin with dark circles under my eyes and age spots. I can't believe how well this covers and lasts, I don't need any other product on top. At least I'm not wasting money anymore on things that look thick and cakey on."

"I was sceptical with it being white in the bottle. But having a pale skin colour makes it so hard to get a good match, I always end up looking like either an Oompa Loompa or Casper the Ghost when I'm going out. This actually matched, even in daylight."

"I get so little sleep with work pressures and it was starting to show. This evens my skin out and I end up looking well rested, which is quite an achievement believe me. One pump covers my entire face. Bye bye to all my other foundations."

"Over the years I've spent hundreds of pounds on expensive brands that promised a lot but didn't deliver. Trust me, this is the one. It even matches my skin when I have a tan. I get so many compliments now, beautiful skin, glowing, radiant. Ordering my third bottle."

"Tried everything from Boots own brand up to the posh counters, always the same story, cakey by lunchtime and sitting in my lines. Wore this to my daughter's wedding, cried half the day and it didn't budge. I'd have paid double if I'm honest."

Start on clean, moisturised skin. Dot on one pump and blend outward with your fingertips or a brush. The shade develops as you work. Build a second light layer anywhere you want more coverage. No primer or powder needed.
Up to 16 hours of comfortable wear. It won't oxidise, fade or transfer, and stays breathable and lightweight all day.
One layer gives a natural, skin-but-better medium coverage. Sheer it out with less product, or layer a little more where you want it. It builds without ever looking cakey.
It's a gentle, non-comedogenic formula made with skin-soothing Vitamin E, designed to sit comfortably on sensitive and mature skin.
