Begin the Battle Against Breakouts

Don't let eruptions on your back, shoulders, chest, or butt force you to eliminate slinky tops and skimpy bikinis from your summer wardrobe. To ward off new spots while dealing with existing ones, start this daily blemish-busting regimen from Los Angeles celebrity dermatologist Howard Murad: First, suds up the offending areas with a body wash that contains pore-unclogging ingredients, like salicylic acid and gentle buffing beads. He created Murad Ache Body Wash, $35. You can also try Neutrogena Body Clear Body Wash, $5.99. Pro tip: Let the cleanser sit on your skin for a few minutes before rinsing it off so your bod can reap all the anti-acne benefits. Post-shower, dry off and then mist your back, chest, and rear with an antibacterial body spray (they're the best for hard-to-reach areas). We suggest Clinique Acne Solutions Body Treatment Spray, $19.50. And don't forget to spot-treat during the day. You can enlist the same zit-zapper you use on your face (it should contain at least 2 percent salicylic or sulfur acid). Two powerful ones: Benefit Boo Boo Zap, $18, and Biotherm Acnopur Emergency Anti-Ache Treatment With Salicylic Acid, $12.

Summerize Your Purse Primpers

Don't stash so much stuff in your bag that it's too bulky to tote. Be prepared but pared down with these hot-weather beautifiers.

* Try a blush with three hues to create the ultimate cheek look. Lumieres Magiques de Chanel, $50 (a), has a trio of pearly pale purple for highlighting, pink for contouring, and fuchsia for a bright flush.
