The Doctors welcome Dr. Mike Varshavski to answer some of your pressing questions about your skin.

Best way to prevent chapped lips?: Dermatologist Dr. Sonia Batra says a natural approach is to use olive oil a couple of times a day. If you are using a lip balm, she suggests avoiding ones containing scents, dyes, and colors as they can be irritating to the skin. She also recommends a lip balm that contains an exfoliant, like ones containing a small amount of salicylic acid or beta hydroxy acid. She says these can help sluff off the dead and dry skin.

Can I use regular body lotion for my face too?: Dr. Varshavski explains that body lotion has a higher amount of emollients and can cause breakouts if used on the face. He says they often also contain scents, which he advises against using on the face. Dr. Batra adds that if you are dealing with acne or are prone to breakouts to make sure the lotion has been formulated to not clog pores.

What to do about large visible pores on the nose?: Plastic surgeon Dr. Andrew Ordon says pores "are meant to be on the nose." He says there is nothing you can do to get rid of pores -- and notes you would not want to. He suggests making sure to keep them clean and unclogged and to have a good skin regimen that includes exfoliation. To temporarily shrink your pores, he says an astringent can be helpful.
