Finally, we have a 70 year old, who had no history of acne but is currently suffering from eruptions on his upper lip. Is there anything he can do to regain his clear skin? Firstly, stop using any products that may contain irritants such as sodium lauryl sulphate (found in shampoos and toothpastes). Try drying out the acne with a paste made from green clay or Fullers earth, writes one reader. The paste will draw out the impurities and clear the skin within a few days. Or the problem could be internal. Intolerances to certain foods can come on suddenly at any age and it may be that one's system is trying to get rid of the toxins through the skin. Try avoiding the usual culprits for food allergies, such as wheat, yeast, dairy etc. Also steer away from refined oils and fats, sugar and salt.
