The main ingredients both pregnant and breastfeeding ladies should avoid are Vitamin A and its derivatives (Retinol, retinoic acid, etc.), BHAs, and a lot of the nasties we don't use like parabens and phthalates! We provide full disclosure of all our ingredients in each product so please refer to those in the product descriptions. The Bergamot Essential Oil we use is bergaptens free and used at low levels, well within the strictest of standards upheld by the International Fragrance Association (IFRA). If you have any doubts or questions we always suggest talking to your doctor before introducing a new product onto your skin.
