Having recently celebrated a milestone birthday (cough, 30), I know I need to take preventative measures to make sure my skin stays youthful for as long as possible. While I want to hydrate and prevent fine lines, I don't want to contribute to my occasional adult acne -- and so many moisturizers and serums have a tendency to break me out. Kate Somerville Wrinkle Warrior 2-in-1 Plumping Moisturizer + Serum, $95, tackles all of my skin-care concerns without a single blemish.

Wrinkle Warrior packs a hydrating and anti-aging punch by combining serum and moisturizer into one multitasking product. It contains hyaluronic acid in three different sizes to plump up the skin, fill in fine lines and prevent deep wrinkles from forming. I apply it morning and evening to my face and neck -- it glides effortlessly over my skin and absorbs quickly. It creates the perfect, smooth canvas for my foundation without causing it to slide off or appear greasy.

It also comes conveniently in a shatterproof, 1.7 oz. bottle that is completely TSA-friendly. Needless to say, I am stashing this one-step wonder in my carry-on for my trip to Italy next week.

It's no secret that I'm obsessed with all things dewy, shiny and radiant, and you can usually find me rocking a high-wattage highlight or a dewy complexion. To me, shiny is sexy, and I'm all about channeling my inner vixen. While most stop at the face with their glow, I'm not ashamed to admit I'm a little bit "extra," and like to shine from head to toe, which is where Nivea Nourishing Body Oil, $8.99, comes in.

Straight up, this drugstore gem makes me feel like a Victoria's Secret Angel, and it certainly pampers my skin like one. While I'm normally hesitant to reach for body oils -- due to their reputation of being heavy and greasy -- this lightweight oil sinks into my skin in less time than it takes to pick out an outfit. The macadamia and avocado oil elixir deeply hydrate my usually-dry post-shower skin. And that's not even the best part.

What I really love about this body oil is that it serves as an all-over body gloss, which instantly boosts my confidence when I'm showing a bit of leg. It also enhances my spray tan by about a million percent. In fact, I usually find myself sashaying down the streets of L.A. when I'm wearing this. So if you want to glow from head to toe (and own your sexy), skip Victoria's Secret and hit the drugstore. You'll have the same confidence-boosting results for a third of the price. Though the body oil would pair nicely with a new lingerie set...

The path to my Sephora VIB Rouge membership has been paved with regrets. This is why I should have known better than to go to Sephora on a day when I was stressed, bored and distracted -- the impulse shopper's perfect storm. Among the many items that landed in my basket while I gossiped on the phone was Drunk Elephant T.L.C. Sukari Babyfacial. At $80 for less than two ounces, this luxury face peel had the makings of a VIB -- very impulsive buy.

But OMG -- this is the most legit beauty product I've bought in months. After one use, this peel did more to lighten the dark spots on my cheeks than weeks of blasting them with retinol and hydroquinone; as a result, I applied my face makeup in half the time. On the skin-smoothing and brightening front, this product is at least as effective as any of the professionally administered facials or face peels I've had. And if one application of Babyfacial beats the results of a $100-plus spa facial, then this product really is a VIB -- very incredible bargain. --Katie McCarthy

I have no idea what happened this spring, but I woke up one day and my hair was a frizzy mess. It stayed that way for weeks, regardless of the weather and what products I used. Needless to say, I got pretty frustrated -- I was even considering plunking down a wad of cash for a keratin treatment for my previously manageable hair.

Then, I remembered I had a bottle of Bhave Magnify Volumizing Shampoo, $32.95, tucked into the back of a cabinet in my bathroom, and I figured I'd give it a try -- the name alone gave me hope. It's made with a special keratin extracted from the wool of New Zealand sheep that's designed to repair and soften each hair strand. And it also contains organic aloe, macadamia and evening primrose oils, and no parabens, sulfates, or sodium chloride -- so there's nothing not to love.

Sure enough, after just one use, my hair was silky as a lamb. But because it's a volumizing formula, it also looked thick and full. Now, even on rainy days, if I use this shampoo (and its matching conditioner), the frizz stays away -- no keratin treatment required. -Dawn Davis

OK, OK, so technically I you can't "empty" a makeup brush, but that doesn't make this product any less worth of the praise I'm about to heap on it. You see, powder brushes usually fall into two camps: supersoft and ginormous, or somewhat prickly and tapered for precision. However, EcoTools' Full Powder Brush, $8.99, brings the best of both worlds. It's soft and fluffy, but it also has a convenient pointed end, perfect for setting under-eye concealer and navigating the narrow area between my brows. I tend to use it exclusively for applying powder (which I have to do every day, thanks to my oily skin), it could easily double as a bronzer or blush brush.

Then there's the price. Though makeup brushes are one of the beauty goodies I'm willing to splurge on, this one proves there's no need to. This drugstore tool resides on my vanity next to a powder brush literally 10 times its cost, and yet this is the one I reach for. --Mary Squillace
