Research is underway to determine if lipids in anti-aging cosmetics might have an effect on prenatal brain development. Though at present researchers cannot find a direct link, it has been proved that abnormal levels of lipid molecules can affect brain development in fetuses. High levels can affect two key neural pathways which can trigger autism. The lipids in cosmetics that are being researched heavily are cholesterol, palmitic acid and ceramides.
A high level of the lipid Prostaglandin E2 (PGE2) in the brain can affect Wnt proteins which have been implicated in a number of autism studies. Statistics currently show that 1 in 68 children have autism (Pitman, 2014).
