Summer beauty

(In Style) -- As everyone knows, if you want that healthy summer tan, the safest way to get it is from a bottle.

We've done the research, and here's what we recommend.

If you're fair-skinned, look for a creamy self-tanner.

The emollients in cream formulas dilute the DHA, the tanning agent, so the resulting shade is lighter and more natural-looking.

Plus, creams help hydrate dry skin, regardless of type. (Try Decléor Sun Self-Tanning Hydrating emulsion SPF 4 for face and body, $26; 800-722-2219.)

Gel formulas work well on medium skin tones because the DHA is more concentrated, resulting in a warmer color. (Try Clarins Self Tanning Instant gel, $25.50; at department stores.)

Darker skin tones should choose an oil-free spray. They produce the darkest, richest colors, which helps counteract ashiness. (Try L'Oréal Ombrelle Sunless spray in Dark SPF 12, $9; at drugstores.)
