Selenium You may have a selenium deficiency. If your daily vitamins don't have selenium, take a selenium supplement for a few months. In many areas of the country the selenium content of the soils has been depleted so that we don't get enough in our regular diet. An antioxidant, vitamin C helps tissue repair. You may use castor oil at night instead.
Vitamin E is an antioxidant that slows aging and aids in tissue repair.
Zinc Another mineral supplement to take is zinc. Take 15 mg a day for one to two months. Don't take more than 15 mg without a doctor's supervision, as it may hinder the body's absorption of other minerals, especially copper. Rubbing fresh aloe vera juice or gel on the spots will help fade them. Use the gel twice a day for a month or two.
