Unfortunately, shea butter does not have a significant effect in treating acne scars. In fact, though shea butter can be a very effective skin moisturizer, it should not be used on acne-prone skin as it can clog the pores and cause or exacerbate acne breakouts.
Acne scars are caused by damage that is deep in the skin’s dermis layer. While most post-acne dark spots (i.e. hyperpigmentation) can be treated effectively with a medicated dark spot remover, the only way to reduce real acne scars is by treatments from a dermatologist or a licensed esthetician with a device that uses a technology called micro needle RF (radio frequency). This technology inserts very thin needles into the skin, heats the dermis and triggers the production of new collagen fibers. These new fibers fill up depressed scars and improve skin texture.
