Here are some natural products I have successfully worked with over my many years in the natural health foods and supplements industry.
Vitamin A: Helps reduce sebum production.
Selenium: An important antioxidant nutrient that functions in the enzyme glutathione peroxidase. This enzyme is very important in preventing the inflammation of acne.
Zinc: Important in the healing process. Also involved in the proper metabolism of testosterone, which is part of the sebum production cycle.
Vitamin E: Helps in the transport and utilisation of vitamin A. Also supports and activates selenium.
