According to a survey by a consumer group in the United States, an independent study found that lead was detected in a majority of lipsticks in the US cosmetics market. Japanese lipsticks are no exception.
In 2007, 685 cosmetics were found to contain lead, according to a survey by the US Food and Drug Administration (FDA). However, the amount of lead absorbed from the skin by licking the lips is very small and not enough to cause health damage. However, lead will accumulate as you continue to use it.
If you are born with high melanin pigmentation and want to lighten the dark color of your lips, Lip neutralization is used instead of lip whitening.
