Still happy after 9 months
Have been using Proven for about 9 months now. Ingredients don't seem to be changing shipment-to-shipment, but what I get has been working. Occasional breakouts still occur at the start of a set. Not sure if the retinol is supposed to be getting harsher/stronger as I go, but current level is pretty weak. Site redesign is user friendly and easy to update, but haven't gotten enough sets to notice if specific texture changes affect formulation (i.e. requesting a more exfoliating cleanser, etc.).
