If your skin was freaking out in 2020, then the new Allies of Skin Prebiotics & Niacinamide Pore Refining Booster (£65) may be just what you need to calm things down. The booster, which can be used on its own or mixed with serums and moisturisers (although, always tread with the utmost caution when combining active ingredients), contains niacinamide, which is an ingredient loved by dermatologists for its ability to minimise the appearance of pores and fine lines, revive skin tone, and, most notably, decrease inflammation, which helps with issues like acne and rosacea. Not only that, but it also contains centella asiatica, another soothing ingredient, as well as prebiotics and probiotics to help your skin's microbiome stay balanced and healthy. All combined, this hard-working booster is bound to make skin happy in 2021.
