Laser Induced Breakdown Spectroscopy (LIBS) technique was applied to

determine the concentrations of different toxic elements like lead,

chromium, cadmium and zinc in four different lipstick brands sold at

local markets in Saudi Arabia. These samples contain toxic elements

like lead, cadmium and chromium which are carcinogen dermatitis,

allergic and eczematous. Their extraction from human body takes over

40 years and accumulation in the body cause problems like disruption

of nervous systems and kidney damage. They could trigger to systemic

lupus erythematosus (SLE). In order to test the validity of our LIBS

results, standard technique like (ICP-AES) was also applied. To the

best of our knowledge, this is the first study where LIBS technique

was applied for the measurement of toxic substances in lipsticks. The

maximum concentration detected in four lipstick brands was much higher

than the permissible safe limits for human use and could lead to

serious health problems. It is worth mentioning that the lipstick is

not a solid rather is in fluid state which is not trivial to analyze

using LIBS technique. For this purpose, special treatment of the

lipstick samples was necessary to analyze with our LIBS method.
