Acne is caused by biofilm type of bacteria - I would suggest using macadamia nut oil which has been shown to help Acne since it contains a fatty acid that helps break up biofilms. You might want to consider using essential oils topically
I don't mean to be contrary to the Liver Flush Forum but this is a good way to stimulate the gall bladder/bile flow but not effective for deep cleansing of the liver. I would suggest using a herbal product like Planetary Formulas Buplernum with cysteine and make sure you are getting adequate b vitamins to stimulate methylation which is important.
You may want to consider strengthening the gut which is a large part of the immune response, use colostrum and some probiotics. Getting the intestinal tract cleansed would help as well.
I would also consider supplementing vitamin A since it helps immunity and the skin. And have your vitamin D levels checked since it is an important part of immune response.
