Dr Phillip Artemi, a Sydney dermatologist and member of the Australasian College of Dermatologists, says the best advice is to keep skin care simple. "The average woman uses 8-10 skin care products a day. If each [product] averages 15-20 ingredients this represents a total of up to 200 different chemicals applied to the skin in one form or another each day — it's a wonder some women have any skin left. The fewer the number of products applied to the skin, each with as few ingredients as possible, the better, if you want to avoid irritation and the risk of developing dermatitis."
