And you can't make any references to medical conditions like acne, eczema, etc. otherwise it has to be treated as a drug. I think even "may help with" is a medical claim. Feel free to say things like "soothing", "mild", "cleansing", "balancing", "moisturizing", "for combination skin", etc.............
To clarify on this point - in the US, if you say anything about "moisturizing" then you need to label it as a cosmetic and follow all the laws for that. Soap can cleanse. If you say it does anything other than that then you are in the cosmetic or even drug areas
