To find out the breakdown on where you should invest your makeup dollars, read more.

Amp up your striking white nail polish look with gold studs at the base for a simple but impactful touch. Opaque white nail polish packs quite the punch, but it also tends to show mistakes a lot more than other polish hues. So to make sure it looks its best, first file your nails for a perfect shape and trim your cuticles to ensure clean lines around the edges.

To create the look, I started off with Butter London Nail Fertilizer ($18) as a nutrient-rich base coat. Then, I painted on two coats of Chanel Le Vernis in Eastern Light ($30) for pure white coverage. While the polish was still wet, I added a gold stud from The New Black Rock and Roll Royalty Set ($24), which comes with various polish hues and a bottle of edgy accents, including gold studs and black and clear rhinestones. To finish, I topped this look with Essie Good to Go ($8) to seal in the stud and give my nails a glossy finish. If you have any messy edges, go back with a brush dipped in polish remover to clean up any stray polish.

Ciaté is known for taking the nail-art trend from the streets to the comfort of your own home with its easy DIY kits, like this Very Colourfoil Manicure Set ($25). The end result is a colorful and intricate design that looks far more complicated than it really is. To see how to use this genius kit, just keep reading.

The fragrance industry sees so many new launches every season with plenty of bottles being discontinued, so celebrating the 10th anniversary of Narciso Rodriguez For Her ($25-$104) is a big deal. As a longtime fan of this soft, sensual scent, it's easy to forget just how much this was a pioneering fragrance back in 2003. From it's black opaque bottle to the key note of musk, by description it sounds like men's cologne, but the designer himself was keen on pushing forward with all of his unconventional ideas for his first-ever women's perfume. His original vision paid off, and it has garnered quite the cult following. The blend of musks mixed with floral notes like orange blossom, osmanthus, and rose make this a warm, feminine scent that is sure to stand the test of time.

If you're headed off to a wedding that's set in a remote location, beautifying as a guest, bridesmaid, or even the bride can be a challenge. From not being able to tote your entire hair and makeup stash with you to no salon in sight, you might have to pull a beauty MacGyver. Or perhaps you just want to look fabulous without making that trip to the salon. Find out how you can fake a professional service when you keep reading.

When you already have a moisturizer for your face, it can feel a little redundant to have an eye cream, too. But the delicate skin around your eyes deserves a little extra TLC. See the many benefits of eye cream, along with a few product recommendations, when you keep reading.

Not popping a pimple is one of those cardinal beauty rules that is often broken, but there are things you can do to lessen the damage if you do choose to squeeze. Your best bet is to leave your extractions to the pros. But if you can't resist the urge, take some advice from celebrity esthetician Renée Rouleau. "If you are going to squeeze a zit or blemish, make sure you aren't making it worse and creating further damage to the skin," she says. "The issue isn't just the blemish itself, but the red, dark, or purple mark left over from picking can linger for months. So the goal is to get the infection out of the skin in the least invasive way." Learn how to do that when you follow these steps.

When you think of an eye pencil, eyeliner is probably the first (and maybe the only) thing that comes to mind. But considering I'm a liquid liner user, the Chanel Sculpting Eyebrow Pencil ($29) is the only eye pencil in my everyday makeup bag. I love that it not only has the perfect amount of brow pigment on one end — it goes on light, but totally buildable — but it also has a spoolie brush on the other end. This makes grooming and filling in my brows fast and easy.

The one makeup artist tip I love is to find a color one shade lighter than your natural color is so it subtly shades without making it overpowering. And in case you think you don't really need to fill in your brows, once you try it, you won't feel the same without nicely groomed brows.

Lauren Conrad has made a business out of selling her style, from her clothing line to her website thebeautydepartment.com, and we still can't get enough of her covetable beauty looks. Lauren let us in on what's stocked in her makeup bag and what's always on her vanity.

On her signature cat eyeliner: "I use Mark. I worked with them years and years ago and I never stopped using it. I've tried so many different brands, and every once in a while I'll switch it up for a softer shade and use a light brown. Chanel does a good one, but [Mark] is my go to. It's waterproof, so it doesn't smudge!"

Her tip for summery beach waves: "I think the trick is less product. I don't use a lot of product in my hair, and also differentiating the size of the curls. So you curl inside the barrel, then over the barrel, and switch it up to give it a little bit of texture. Beach waves aren't supposed to be fussy, so you're supposed to do them quickly. They're supposed to be imperfect."

Her signature scent: "I wear Chanel Chance ($68-90). There are many of them, but I use the light pink one."

What she always travels with: "When I travel, I use neroli water ($40) — it's a hydrating thing. It's really nice to keep with you especially if you are doing a long press day to refresh your makeup. You could actually use Evian spray ($11) too, but I like this because it smells like orange blossom. I always travel with that and Egyptian Magic ($37), because every night I do a scrub to get all of my makeup off, and I slather it on after because when you fly, your skin gets so dehydrated."

I was over the moon when Essie first released its Sleek Stick nail wraps, and now there's a new Summer 2013 collection with six fresh designs. The hot-pink Small Pleasures ($10) design caught my eye. I love the vibrant color, but it was the textured 3D design and the unique take on floral nail art that won me over. Plus, they're a breeze to apply! Be sure to start off with clean hands and nails to ensure the adhesive sticks. Then find the right size appliqué for each nail. Just peel off and apply to your nail, and use the included tool to help smooth out each wrap and get rid of air bubbles for a tight fit. Use the included file to remove the excess, and you're good to go. Which one is your favorite?
