During the last decade, usage of personal care products has rapidly increased among Sri Lankans and the local markets were crammed with numerous cosmetics and personnel care products which were regulated by the Cosmetics Drug Devise Authority (CDDA) considering the health safety of Sri Lankans

To fulfill these regulatory purposes the chemical analysis of cosmetics was initiated in the year 2009 as a separate unit under the Chemical and Microbiological Laboratory as the first ever Cosmetic Testing Laboratory of the Country.

As a Market Basket Study, the face creams that were available in the country were analyzed for heavy metals. In the study it was revealed that the Mercury content of some imported products are higher than the permitted levels.
