Tati Westbrook, Birchbox Beauty Expert and YouTube Star

Must-Haves:
"Every single day I use the Beauty Protector Protect & Detangle, $21.95. In fact, I'll even use it between washdays on the very ends of my hair because it tends to get supertangled. My hair is fine and thin, and this product makes any comb go straight through it. It smells very vanilla-ish and cotton candy-ish, and it's a heat protector, styler and detangler all in one.

For the face, I have two items that I pretty much stick to and don't really change. The first is the Balm Cosmetics Time Balm concealer, $18. I'm wearing it right now. I use it as my eyelid primer and under my eye. It doesn't crease and it's just ultra everything. I will stray and test out new products, but I always go back to that one. I've been using it for almost a decade. It's one of those must-have holy grail items.

Another product that I will actually use to set the concealer, eye primer and foundation is Laura Mercier translucent powder, $37. It's the best. I even apply it with a damp sponge and it doesn't bunch up. It's just a beautiful powder.

I'm also really into face masks. My favorite is Dr. Jart, $6. I put it on my face and half an hour later my skin is very smooth and hydrated. So it's my after-travel, must-have mask, and if I'm going to an event, it's like a save-your-face mask.

I'm a product junkie all the way, through and through, but one of my must-haves is the Anastasia Beverly Hills Brow Wiz. You'll find a product that's really close but it's not the same. With how many products that I try, if there are those items that I keep going back to then I know it's true love."

Angela Lanter, Hello Gorgeous

Must-Haves:
"I like to use Pixi Glow Mist, $15, before applying my makeup, then again once my makeup is complete to set a gorgeous glowy look in place.

It's so important to fully prep your skin before makeup, and Cover FX Anti-Aging Primer, $38, is great for filling in fine lines so you can get an even, beautiful makeup application.

Every woman needs a little bronzer in her life. I love the formula of the Too Faced Chocolate Soleil Bronzer, $30, because it's matte and great for contouring.

Gerard Cosmetics Lipsticks, $19, aren't just pretty in their little gold tubes -- they pack a colorful punch. I love the pigment and formula.

What girl doesn't want a collection of pretty purple makeup brushes? Makeup Addiction Cosmetics Brushes, $6-$23, have the softest fibers -- perfect for blending."

Stephi Maron, CEO & Founder of Blushington Makeup and Beauty Lounge

Must-Haves:
"I use Natura Bisse SPF 50, $97, in the morning before I put on my makeup. [This CC cream] acts like a primer with SPF. I like to wear this on the weekends or when I want to give my skin a break from using foundation.

Beautyblender, $19.95: Can't live without this. I use this to apply all my products on my skin.

I use Julie Hewett Concealer, $22, to conceal any blemishes and my under-eye area, and then use Bobbi Brown concealer, $28, to highlight my t-zone area.

I never leave the house without filling in my brows with Billion Dollar Brows pencil, $18. You don't need to use a lot -- it really fills in well.

I only use Kevyn Aucoin The Volume Mascara, $28. Fun fact: When I go to Hot Pilates or SoulCycle I usually have mascara on from work, and when I am done my mascara is still in place.

I am absolutely obsessed with Charlotte Tilbury's highlight and bronzer duo product, $68. It's very soft and leaves a natural finish but gives you this natural light contour and highlight. I use this every day, as well as her cream blush, $45."

Linsday Goldenberg, Woman Getting Married

Must-Haves:
"I started paying attention to product ingredients a few years ago, and have really cleaned up my skin care routine since then. I feel like I've tried hundreds of products, but the Dr. Alkaitis line is my favorite. Their organic day crème and night crème are one fluid ounce and perfect for flying.

I was breaking out a lot a couple of years ago, and the Boscia Konjac Sponge, $15, completely saved me. I use it with my facial cleanser, morning and night, and I never travel without it.

I hate the way sunscreens feel. If it's thick, greasy or smells too fragrant, I won't wear it. The Skinceuticals Sheer Physical UV Defense SPF 50 is the only one I've found that feels like I'm wearing nothing, which means I'll actually use it everyday."

Dawn McCoy, Beauty Frosting

Must-Haves:
"If you haven't tried Charlotte Tilbury yet, get thee to Nordstrom, STAT! I love the Dolce Vita eyeshadow palette, $52, the Colour Chameleon crayons, $27 (they stay on ALL. DAY. LONG) and my latest and greatest find -- the Charlotte Tilbury Goddess Clay Mask, $70.

I fell in love with this new Tarte Lipsurgence skintuitive lip gloss, $29 instantly. It plumps lips and reduces the appearance of fine lines, all while leaving you with a natural lip color unique to you.

Jouer Cosmetics Luminizing Liquid Highlighter, $39 is my magic wand of the moment! I love applying this on the tops of my cheekbones, on the apples of my cheeks, in the inner corner of my eyes, right above my cupid's bow, and on the tip of my turned-up nose for instant light reflection and dewiness.

I just finished Diane Von Furstenberg's "The Woman I Wanted To Be," and I cannot recommend it highly enough. Fun fact: I have always blow-dried my hair sitting down at my vanity, and I love the time it gives me to read books, like this one. I am a multitasker supreme!"
