We'll ask whether you're pregnant or nursing when you complete your skin profile. If you indicate that you are we'll automatically exclude certain ingredients. If you're pregnant we'll exclude retinoids and salicylic acid. If you're nursing, we'll exclude retinoids. If there are other ingredients you'd like to avoid you can let us know these preferences in the comments field on your skin profile. Always check with your doctor before using any new products while pregnant or nursing.
