When pop sensation Sabrina Carpenter shared a TikTok video talking about her favourite lip balm, she described how it absorbs the lips’ natural pH and “brings out this beautiful pink” and keeps them “super moisturised.”
The product went viral, as did the concept of pH-reactive make-up. Now every time you scroll you will see influencers putting on white foundation that magically transforms into a perfect match for their skin colour, or ink coloured lipstick that morphs into the perfect lip hue.
