What the brand says: 'Say goodbye to overcomplicated routines and say hello to one solution for all types of hyperpigmentation. This highly effective, concentrated serum works by targeting various points of the pigment production process, helping to fade multiple types of hyperpigmentation, from post-breakout marks to melasma, as well as redmarks. Sameeha Shaikh, beauty writer, says: 'Hyperpigmentation issues have followed me since my first breakout when I was 18. Which is why arming my routine with a hard-working serum that is capable of stopping post-inflammatory hyperpigmentation before it can manifest on the skin is so important. It means there is one less skin stress to worry about.'
