Cosmetic contact allergy is commonly seen in patients undergoing patch test
ing, with fragrance one of the most frequently implicated ingredients. Many
cosmetics contain plant extracts either as a fragrance or for medicinal pr
operties, With a vogue for natural products there is an increase in their u
se. We have performed a prospective study over a 2-year period looking at t
he prevalence of contact allergy to plants in patients diagnosed with cosme
tic dermatitis. In addition, we have performed a review of the products of
two popular cosmetic companies, examining product labelling and the prevale
nce of use of plant extracts. We suggest that patients allergic to fragranc
e be advised to avoid plant extracts, which are separately labelled, in the
ir personal care products.
