The self-tanning agents, and all other ingredients used in Bronze Leaf products, are not dangerous for use with clients who are either pregnant or lactating, as a skin application. The tanning solution does not penetrate past the dead skin cell surface layer, nor into live tissues or the blood stream, so it is safe to use.
The active ingredient in Bronze Leaf is dihydroxyacetone (DHA), which is a type of organic sugar. It is non-toxic, and works by interacting with the protein of the skin cells in the top layer of your skin where the cells are dead, resulting in the production of a brown pigment called melanoidin.
It is therefore safe for you to use Bronze Leaf tans during pregnancy.
When getting a Bronze Leaf spray tan applied in your nearest Bronze Leaf Salon, make sure the room is well ventilated and always use nasal filters.
Fake spray tans can occasionally cause allergic reactions, even if you have not had a reaction to fake tan before. Your skin can become more sensitive during pregnancy due to changes in your hormone levels, so always carry out a small patch test first, to see if you are allergic to the ingredients, even if you have used the product before you became pregnant.
