Zinc's anti-inflammatory properties make it a common treatment for acne, which occurs when the skin produces too much sebum. This clogs pores and causes inflammation, leading to painful acne lesions.
The same anti-inflammatory properties of zinc are beneficial for other skin conditions, such as rosacea and eczema. Oral and topical zinc has long been used to promote healing and treat wounds and skin ulcers. Numerous studies have shown that zinc can also help treat warts. Topical zinc ointment can also help treat scars and keloids, and may help prevent skin cancer when used as sunscreen.
