Hi Heidi, I know this is an old post but i've just come across it and thought it would be worth typing an update for anyone else.
Try using organic makeup and skincare products. I know, it's quite radical to move away from your usual brands, especially to organic and natural. But we've had some amazing results and feedback from clients. It seems that trying to fight fire with fire (ie. chemicals with harsher chemicals) just doesn't work in the long run and can end up with further complications. We've found that using natural and organic products allows your skin to breath with clients regularly saying how it feels so light.
In another case we recently we had feedback from a client who purchased our Jasmin Rose Water Mist. She has very bad adult acne and was prescribed steroids. Her dermatologist said the treatment would dry her skin and make it flaky. But after using the Rosewater Mist throughout the day during the 3-4 weeks of treatment there was no loss of skin or flaking. Her dermatologist was amazed.
