Shea butter does not cause acne, but can help fight and prevent acne due to high levels of vitamin A and vitamin E. Shea butter also contains anti-bacterial properties, which help to fight acne, according to Simple Daily Health.
Shea butter is often used on the skin to help heal damage and replenish collagen. However, shea butter is also known for its anti-inflammatory properties, which can help reduce acne-inflamed skin. To treat acne, Shea Butter Guide recommends using unrefined shea butter. Refined shea butter goes through a process that removes many of the healing properties found naturally in unrefined shea butter, which can make it less effective in treating acne.
