I'm a bit of beauty product fanatic (job hazard!) so my cabinets are over-full, but whenever anyone asks me for the one product I think they should invest in, my answer is usually the uber-popular, forever five-star-reviewed Sunday Riley Lactic Acid Treatment. And it's currently on sale for $85 at Space NK.

Our beauty editors have written about this extremely effective and universally beloved product a number of times—e.g., when it was a Dermstore's best-seller, when it was one of seven products worthy of buying at the Nordstrom sale, and when it was one of eight products worthy of a splurge, according to you guys, to name a few.

And it's not just clever marketing—good genes! genius!—that makes this serum special. The groundbreaking product combines gently exfoliating lactic acid with brightening licorice extract and hydrators like aloe vera to form a sort of skin-care perfection trifecta. And it really works, hence the innumerable five-star reviews you can find scattered all over the Internet.

It's not always the easiest to spend your hard-earned cash on a vanity product that may or may not even do anything but make you feel fancy. I would argue, however, that not only is this product worth every penny in terms of results, but also that surviving this year justifies any and every self-care expense. And at $85, I'd stock up on enough Sunday Riley supplies to last until this time next year (their other best-sellers are on sale, too!).
