Can meladerm skin lightening cream be used during the first trimester of pregnancy?

The list of ingredients in this product is very long indeed. Not all of the ingredients have been tested in pregnancy.  Although absorption of these ingredients into the bloodstrem would be small, it would be safer to use it after delivery and nursing.  Vitamin C cream that is 10% or more L-ascorbic acid at a pH of 3.2 or less, such as SkinCeuticals, and 10% or higher glycolic acid creams, can be helpful and are safe.
