Even more worrying is the widespread habit of bleaching one's skin during pregnancy, according to Ly, who says it is fashionable for women to look fairer at the baby's presentation party.
During pregnancy, the woman's skin is even more vulnerable and there are worries that the corticoids contained in some creams may increase the risks of diabetes for the baby.
According to Ly, some cosmetic companies act irresponsibly. They don't always clearly indicate on the tube that it contains dangerous chemicals, she said.
Sadly, many women who realize that these creams are harmful find it difficult to kick the habit.
"As soon as they stop," said Ly, "their tone becomes darker, and people around them assume they have a problem. So they resume. It's a vicious circle, an addiction."
