The main ingredients both pregnant and breastfeeding ladies should avoid are Vitamin A and its derivatives (Retinol, retinoic acid etc), some strong hyperpigmentation ingredients, and a lot of the nasties we don’t use like parabens and phthalates! We have a whole blog on the topic here.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 bergaptene free and used at low levels, well within the strictest of standards upheld by the International Fragrance Association (IFRA).Likewise where BHAs are included in our ingredients they are introduced at <2% w/w concentrations. If you have any doubts or questions we always suggest talking to your doctor before introducing a new product onto your skin.
