ARK Skin Perfector Clearing Serum, £42
If excess oil is a problem and blemish breakout is taking its toll, then this bad boy banishes bacteria, clearing skin and reducing redness. I had some congestion and redness around my nose and after a week this helped clear it up. It’s calming and clearing, giving skin brightness and clarity while controlling shine. It doesn’t have that chalky texture either, unlike other oil regulators.
