one of Sunday Riley's priciest formulas, and perhaps one of the buzziest, I had high expectations for this all-in-one AHA serum. According to the fine print, it's specifically targeted to deal with dark spots, pores, and wrinkles by utilizing a high-potency form of lactic acid to exfoliate way the dead skin cells that make our complexion look dull or congested. As the brand recommends, I've been alternating this with the A+ Retinol every other night so that I'm lifting away the debris the night after the retinol has worked its turnover magic.
"This product is great on its own but combined with the retinol, it's the ultimate power couple. I've gotten a few facials recently, which could be a contributing factor, but my skin hasn't felt so soft, smooth, clear, and naturally luminous since I started using this serum regularly at night. My only qualm is that I'm not used to using an exfoliating agent like this as a last step before bed, and it can feel a bit prickly and stingy. I know that's part of the deal and the formula, but if you're not a fan of feeling your products working, tread carefully. (Though I promise, the end result is worth it!)" — Erin
