Zinc is an essential mineral that may help treat a number of skin conditions including acne, as well as protect skin from the damaging effects of the sun. Zinc can be taken as a dietary supplement and is also a key ingredient in creams, moisturizers sunscreens and some dandruff shampoos.
Considerations
Zinc helps maintain the integrity of the skin and mucosal membranes, which are the soft, wet tissue that lines body openings (mouth, nose, rectum and vagina). The National Institutes of Health (NIH) says individuals with chronic leg ulcers are unable to properly metabolize zinc, and are commonly treated with zinc supplements.
Acne
Acne is a skin problem that develops when oil and dead skin cells block your pores. Acne results in pimples, blackheads or whiteheads. Topical or oral use of zinc appears to be a safe and effective treatment for acne, according to the NIH. However zinc may not work for all acne patients.
Dandruff
Dandruff is a common but rarely serious condition that typically causes flaking and itching of the skin on your scalp. Zinc can be beneficial in the treatment of dandruff. Zinc pyrithione is an antibacterial and antifungal agent found in certain dandruff shampoos (Selsun Salon, Head & Shoulders). Zinc pyrithione may decrease scalp fungus that can cause dandruff.
Sun Protection
Zinc oxide can protect your skin from the harmful effects of the sun. A number of sunscreens contain zinc oxide and titanium dioxide, which guard against the penetration of both UVA and UVB rays. Zinc oxide ointment may also help reduce redness and blisters associated with sunburn.
Precautions
Zinc creams and supplements can cause severe allergic reactions (rash, hives, tightness in the chest and swelling of the mouth, face, lips or tongue). It is also possible that the topical use of zinc may worsen acne in some cases.
