A major beauty influencer with over 2 million subscribers on her YouTube channel, Nicole Guerriero is defining our #makeupgoals. In fact, the beauty icon frequently collaborates with NYX Cosmetics, and recently helped open their first East Coast location at the Willowbrook Mall in Wayne, New Jersey. So what's her secret to flawless skin and to-die-for makeup? She reveals all, here.

Must-Haves:
"It took me a long time to find a tinted moisturizer that I really love. That is, until I found the Bare Minerals Complexion Rescue Tinted Hydrating Gel Cream. It's basically a tinted moisturizer, BB and CC cream all in one. It's superhydrating, lightweight and has the right amount of coverage to make this full-coverage kinda girl very happy. It's also fast and easy to apply. I just use my fingers and my skin looks instantly healthy and glowy. It's a perfect summer base."

"My lips need a little extra love in the summer and Best Damn Lip Mask is my holy grail lip product (and I'm not just saying that because I created it). This supercharged lip hydrator is perfect year-round for soft, supple and hydrated lips. I apply a little in the daytime for the perfect pink and (slightly) glossy pout. Then I'll slather it on at night to wake up with beyond-hydrated lips.

"When it comes to my summer makeup, it's all about being lightweight. I love the NYX High Definition Photo Concealer. It's a powerful concealer that brightens underneath my eyes, or adds a little extra coverage anywhere I need it. It's very creamy and easy to blend with medium-to-full coverage, but without the heavy feeling. I pair this with Laura Mercier Secret Brightening Powder, which I use to set underneath my eyes. During summer months I like the dewy skin look, so I don't set my skin, but the under-eye area is a must, especially if you want to avoid creasing. This transparent powder really does brighten, and fights all signs of creasing without ever looking heavy.

Sometimes during the summer I can't be bothered to wear false lashes. Enter my favorite mascara of all time: L'Oréal Voluminous Carbon Black Mascara. I'm convinced this volume-building mascara has magic dust sprinkled in it. One eyelash curler plus two coats of this mascara equals no falsies needed.

Is it really a summer look without a summer glow? To achieve my perfect glow, I love using Laura Geller Baked Gelato Swirl Illuminator in Glided Honey. It feels like a cream, but applies like a powder -- creating the perfect amount of glow without overdoing it."

"I love using my Elizabeth Arden Anti-Aging Antioxidant Infusion Essence to help keep my skin looking radiant and healthy throughout the day. Following that, I apply one of my favorite brightening serums from Tata Harper, the Concentrated Brightening Serum, to keep my skin nice and moisturized. To top it off, I always put on a day cream. My go to is the Nivea Q10 Anti-Wrinkle Day Cream with SPF 30.

If you haven't tried Maybelline New York Baby Lips yet, you have to. They're my go-to moisturizing lip balm to help keep my lips supple in the mornings. For color, I like to rock a slight tint to my lips, and I love using Tata Harper's Natural Lip Treatment (tinted), which is also 100 percent natural.

My hands tend to get really dry throughout the day. To help with that I run my OPI Avoplex Cuticle Oil on my nail beds, and then I'll apply one of my favorite hydrating shea butters from L'Occitane to help keep my hands supersoft.

When it comes to my strands, I always leave a few days in between washing my hair. So for the days I don't lather up, I'll use Herbal Essences Naked Dry Shampoo to keep my hair fresh and clean."

Must-Haves:
"I'm a less-is-more type of girl, so every product I rely on when traveling is compact and doesn't take up much room. Plus, they allow me to look unencumbered on my plane ride, so I'm ready to hit the ground running the minute we land.

Dior Diorskin Nude BB Cream moisturizes [think: dry plane ride], and makes my skin bright and even for days. In fact, if I don't feel like wearing makeup, this has me covered [literally]. I normally pair this with Kate Somerville Daily Deflector Waterlight SPF 50 Sunscreen -- after all, safety first.

When it comes to my makeup routine, I want to ensure my makeup stays even with all the running around I'm doing, so I use my trusty black Beautyblender to apply BB cream and foundation, and clean up smudges throughout the day. It's the only way I'm guaranteed even coverage. Afterwards, I usually swipe on Saint Laurent Volume Effet Faux Cils Mascara -- it's the perfect product for [pumping up] my lashes without the clumping, and leaves them looking long and clean -- which I prefer. I'm also all about my brows. In fact, I can't leave the house without them combed. So, I use the Secret Service Wax Brow Comb to keep them in line.

To add some color to my complexion (especially in warmer locations), I use a dime-size amount of St. Tropez Skin Illuminator and instantly become a little more brown (and a little less yellow).

Must-Haves:
"I start every single morning by washing my face with Rodan + Fields Soothe Gentle Cream Wash. This is my Holy Grail cleanser. I use it with my Clarisonic, and it dissolves any leftover makeup and impurities.

I also really love Kiehls Rare Earth Pore Refining Tonic -- it's bomb! I recommend this toner to everyone, especially those who have large pores.

I always use a sunscreen. I love Rodan + Fields Mineral Sunscreen SPF 30. I apply right after I tone, because I feel like it sinks right into the skin. This helps avoid any oily residue when applying makeup and a white cast when taking flash photography.

Cover FX Custom Infusion Drops C + Lemongrass Radiance serum seriously makes my face glow. It's so good. Since it has vitamin C in it, it also helps with dark spots.

Finally, I treat my skin with Rodan + Fields Soothe Sensitive Skin Treatment. This is a very hydrating lotion that promotes smooth, clear and healthy-looking skin. It has a luminosity to it that leaves the skin looking youthful, and it helps with dryness, sensitivity and irritation. I cannot go a day without it. Before this, my skin was so sensitive that anything would set it off. Now, I can literally use anything and my skin won't completely hate me after. It's just that amazing."

Must-Haves:
"I have dry skin, so I'm really into beauty oils like rosehip for an all-natural pigmentation solution, coconut to cleanse with and castor for long, strong lashes. I am also a fan of Nude Skincare's ProGenius Treatment Oil, $78, and just ordered the famous Sunday Riley Juno Hydroactive Cellular Face Oil, $98, which I cannot wait to slather on my skin.

I've also used Mario Badescu's Alpha Grapefruit Cleansing Lotion, $15, for years. It's so refreshing, and I love the bright, radiant look it gives my skin after each use. I'm currently rotating between three eye creams and each serves a different purpose. I use Jason C-Effects Ultra C Eye Lift, $20.95, as a dark circle solution, AHAVA Extreme Firming Eye Cream, $58, for nourishing and Tula's Revitalizing Eye Cream, $52, as a base for my concealer and eye makeup."
