"111Skin is known for its super-hydrating sheet masks, but this serum from the brand should be in everyone’s beauty cabinet too. Yes, it is on the spenny side, but it really is worth it. If, like me, you struggle with hormonal breakouts every month, then this serum is going to be a game changer. I’ve been using it for the past three months, and my complexion is now glowy and spot-free on the regular, and that’s thanks to its powerful blend of salicylic acid, colloidal silver, colloidal sulphur and kojic acid, which targets blemish-causing bacteria, reduces inflammation and helps minimise pigmentation marks after a breakout. The serum is super lightweight—perfect for oiler complexions—and it doesn’t dry the skin out like other spot-fighting products do, so you won’t experience any annoying flakiness during the day."
