Pregnancy Caution Skincare Ingredients

During pregnancy, certain skincare ingredients can pose potential risks to the developing fetus. Some ingredients, like retinoids (vitamin A derivatives), are well-documented teratogens and should be strictly avoided. Others, such as certain chemical sunscreen filters and high-concentration salicylic acid, warrant caution and a conversation with your healthcare provider.

We have categorised 48 ingredients into two groups: those that should generally be avoided during pregnancy, and those that require caution or discussion with your doctor before use.
