You owe it to yourself to finally try Sunday Riley's beloved Good Genes Lactic Acid Treatment, which visibly plumps your skin in as little as three minutes and battles postblemish acne scars. If the full-size $105 price tag scares you off, pick up this more palatably priced Sunday Riley Flash Fix Kit ($28), which includes that serum along with a Ceramic Slip Clay cleanser to balance your complexion. Bonus: you can mix the two to create a sleeping treatment.
