By this time of year, your nails probably look like crap. They're peeling; they're splitting -- they're obviously dry and unhappy. Instead of swearing off nail polish completely, choose a healthy, good-for-your-nails formula, and get a treatment manicure. When you use one of these new polishes -- infused with hydrating oils, strengthening botanicals and reinforcing proteins -- your nails will become healthier over time. They're significantly better for your nails than wearing no polish at all -- and they look prettier, too.

Way back when (as in, only a couple of years ago), "bronde" took the beauty world by storm. A breakthrough term to define the ambiguous light brown hair color that wasn't quite blonde, but not yet brown, this high-profile hybrid has arguably become one of the most covetable hair trends (dare we say ever), and has yet to lose steam.

Let's be honest: Valentine's Day tends to bring up complicated emotions, whether you're single or part of a couple -- it just does. (All that pressure to come up with the perfect Valentine's Day idea!) Still, it doesn't have to -- it is a holiday that's essentially centered around the many definitions of love, after all. Plus, there are so many ways to enjoy the holiday, whether that means planning a mimosa-fueled brunch with your favorite gal pals, treating yourself to a nice bubble bath at the end of the day, or packing up all your flimsy pink lingerie for a weekend getaway with your partner (or, we think it goes without saying, all of the above).

If you haven't yet jumped on the glycolic acid bandwagon, it's time to do so. The alpha-hydroxy acid is a tried-and-true favorite ingredient among skin docs for its multi-tasking abilities. "Not only is it a great exfoliator, but it also stimulates the production of both collagen and hyaluronic acid," explains Deirdre Hooper, M.D., assistant clinical professor of dermatology at LSU. Translation: There's really not much that it can't do. Improve texture? You bet. Fade spots? Yep. Help with breakouts? Check. Keep skin smooth and wrinkle-free? Obvi. (We could keep going, but you get the picture.) Since there's no shortage of glycolic acid-based products out there -- you'll find it in pretty much every category, from peels to cleansers to lotions, -- we've narrowed down the options. Ahead, seven glycolic acid products that are most definitely worth trying.

I got my first set of eyelash extensions eight years ago. What seemed like an innocent adventure in beauty resulted in an obsessive relationship I haven't been able to shake. My whispery lashes -- until then, more functional than decorative -- transformed from brownish-blond and barely there to curled, dark, lush and arresting. They made my blue eyes appear wider, more defined and a trillion times more feminine. I was Bette Davis eyes, all day, every day. I was hooked.
