Skin care acids have been around for decades, but ingredients like lactic, glycolic and salicylic acids seem to get all the attention. Lately, a new acid has been gaining steam, thanks in large part to buzzy beauty brand Glossier, which just dropped a product called Solution. Suddenly, polyhydroxy acid is the acid to know.

Black is the new black—at least when it comes to hair care. Charcoal became an uber-popular ingredient in skin care products over the last couple of years, so it makes sense that your favorite hair brands would start adding this detoxifying ingredient to shampoos, conditioners and more. "Charcoal hair products are really good for detoxifying and removing buildup," says celebrity hairstylist Felix Fischer. "They also work as an anti-inflammatory and are great for getting rid of dandruff."

Once the temperature starts creeping up, you may notice your skin looks a little, shall we say, on the shiny side. Your first thought is probably to ditch the moisturizer but using a hydrator will actually go a long way towards keeping your complexion balanced. This spring and summer, think about swapping heavier moisturizers for lightweight facial oils. We know: Facial oils often get a bad rap—and those with oily or acne-prone skin usually think they can't use them—but it's all about finding the right one. A lightweight oil may even help curb the amount of oil your skin makes, says celebrity makeup artist Mary Irwin.

Traditional lipstick is great but it has its time and place. Going to be at the office for eight hours? A red lip is probably overkill if you're just sitting at your desk. Headed to a three-hour bottomless brunch? You're not going to be thinking about touchups as you down mimosas. For those days when you want to keep things low-key (which, let's be real, is probably most days), reach for a lip tint for low maintenance, yet still totally pretty, lip color.

For some, a ponytail is the ultimate lazy-girl, just-can't-even-today hairstyle. For others, a ponytail is an opportunity to get creative with a sleek, polished — or artfully undone — updo. Whatever kind of ponytail wearer you are, there's no reason to settle for basic. It's easy to transform a traditional pony into something special — without much effort. (Just the type of hairstyle we love.)
