A healthy tan is summer's best beauty accessory. Unfortunately, many women still think it's okay to fry themselves with harmful UV light. In fact, 50% of Americans are unconcerned about sun exposure and 1 in 5 will develop skin cancer this year.

Don't put yourself unnecessarily at risk--get the sunkissed look the safe way by using a self tanner. Today's formulas are easier and more natural-looking than ever. We hooked up with self-tanning expert (and the Development Manager for Clarins Skin Spas), Ana Maria Crespo to get her insider tips for a healthy summer glow.

Know your formula
Pick the formula that's right for you. Oily skin should use a gel like Lancôme Flash Bronzer Tinted Self-Tanning Body Gel. If you hate the feel of sticky product on your skin, try a fast-absorbing mousse like Clarins Delectable Self Tanning Mousse SPF 15. Lotions like Beautisol All Seasons Glow Gradual Self Tanning Lotion are great for novices as they have the familiar texture of a lotion. Dry skin will benefit from a hydrating cream like Philosophy The Big Skinny Self Tanning Firming Cream

Do the proper prep work
Even more important than how you apply a self tanner is how you prep for it. Ana suggests you complete any hair removal prior to application to help achieve an even color. It's also key to exfoliate thoroughly in order to remove dead, dry skin that can cause blotches. Be sure to wipe away any sweat or excess moisture from the skin and apply a light moisturizer to ankles, wrists, elbows knees and in between the fingers. This will ensure these naturally drier parts won't darken too much.

Sweep and smooth
Ana suggests starting application on your legs and working your way up. Use long, sweeping, massage-like motions in one direction. Don't rub back and forth in one area as this will create streaks. To get your back, either have someone assist you, or apply self tanner to one end of a wide plastic ruler and sweep on to that hard-to-reach skin. Once you've finished application, air dry for 10-15 minutes and then put on loose-fitting clothing to prevent smudging.

Keep it fresh
To make your glow go the distance, avoid shaving or exfoliating after self tanning. "The dryer the skin, the faster your self tanner will fade," says Ana, so be sure to apply moisturizer daily to keep skin hydrated. Depending on your skin type and the product you use, your tan should last anywhere from 3-7 days.
