Triclosan can also cause significant skin irritation and dryness in many (including me). What do I use instead? Cetaphil bar soap."
—Michelle Henry, MD, a dermatologist at Laser and Skin Surgery Center of New York
Just stick to regular soap and water—there's really no need to use antibacterial soap or hand sanitizers because plain old soap does the trick.

And it's partly because I've seen too much (mild to horrific infections from nail salons that don't properly sterilize tools). What I do swear by for my hands: Bloxsun Sun Gloves with UV protection. I wear them in the car so I don't need to bother with sunscreen. (I hate the tiny sun spots on my hands! I've been lasering them off and don't want them to come back.)"

Here's how the toxins in nail polish affect your body.
Brittany Riboldi/Shutterstock"Having worn latex gloves for many years doing research, I now avoid them since latex is so allergenic. While I never developed an allergy to latex (which comes from the rubber tree), it's more common in people who've had regular exposure to rubber gloves. I don't even wear latex gloves when washing dishes—there are many alternatives."

Here are some other weird things you can be allergic to.
Sunlight and UV nail lamps

If you want to compare the difference between intrinsic and extrinsic aging on your skin, just compare the skin on your breasts and face. The skin is the same age—only the amount of sun exposure differs. So for optimum skin health, I wear broad-spectrum sunscreen SPF 30+, 365 days a year."
—Fayne Frey, MD, a dermatologist in West Nyac, New York and founder of FryFace.com
These are the sunscreens dermatologists use on themselves.
Petroleum-based hand creams

—Debra Jaliman, MD, Assistant Professor of Dermatology, Icahn School of Medicine at Mount Sinai
Besides glycerin, here's what else is in your moisturizer.
