The FDA has broken down different harmful ingredients into five categories, labeled A, B, C, D, and X. According to Dr. Moritz, along with containing aluminum, the sold-out Ultra Glow Loose Powder Highlighter ($14) "also includes aluminum chloride hexahydrate, which is a category C and should be avoided."

The FDA defines category C as having "positive evidence of human fetal risk based on adverse reaction data from investigational or marketing experience or studies in humans." So basically, ditch the highlighter and hope that your pregnancy glow holds up for the next nine months.
