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.
