There has been a two fold increase in the cases of allergic contact dermatitis due to cosmetic allergens in seven years with a majority of cases seen in women, according to a recent Danish research.

A report from Dr. Tatyana Hamilton, MD, PhD from the Department of Dermatology and Skin Science, University of British Columbia, Canada, says that on an average, a woman usually uses over 12 cosmetic products per day with an estimate of over 168 specific constituents while a man uses over 6 personal care products comprising 85 similar components. Fragrances and preservatives used in skin care products have been implicated in the majority of cases of contact dermatitis followed by hair care and nail cosmetics.

Allergic contact dermatitis is an inflammatory response of the skin which when exposed to allergens or irritants results in an intensely itchy red rash seen over the exposed areas, swelling, and/or other inflammatory changes. Unlike the rash from urticaria, that  disappears within minutes or after a few hours after exposure, contact dermatitis usually takes longer to heal, and can take few days to a few weeks after removal of the offending irritant.

In the review published in the Skin Therapy Letter, the authors suggest that Allergic Contact Dermatitis of the skin is caused by a hypersensitivity reaction to fragrances or preservatives used in certain cosmetic products.

There are innumerable cosmetic goods available today in the market which not only includes make-up products but also personal care products such as creams, lotions, perfumes, sunscreens, hair care and nail care products. Each of these products comprise a number of unique individual ingredients and these can range from fragrances, preservatives, antioxidants, humectants, emollients, vehicles, emulsifiers, hair dyes, ultraviolet absorbers,  acrylates, nail polish components, and others.
