This article discusses known and scientifically-backed medicinal treatments for acne, and not alternative cures such as homeopathic and hydrotherapy treatments.
To start off, these are the supplements that are commonly prescribed to those with acne or has had a history of acne: zinc, selenium, vitamin A, vitamin B6, and vitamin E.
Studies have shown that a substantial amount of people suffering from acne and other skin disorders have a zinc deficiency. Zinc has been theorized to have an anti-inflammatory effect, which helps reduce the skin’s reaction. However, too much zinc can in turn cause copper deficiency, so copper supplementation is also necessary if zinc is to be taken as a supplement to prevent acne.
Vitamin A should be taken in light doses because it has a serious potential to cause toxicity. Consult with a doctor regarding vitamin A for acne treatment. Vitamin B6, on the other hand, has been linked as a known treatment supplement for premenstrual acne cases.
Other than the vitamins and minerals stated above, the only other alternative treatment linked with acne backed by studies is tea tree oil, which has natural antibacterial properties. Some over-the-counter products that contain as much as five percent tea tree oil are proven to be effective for mild to moderate acne. While tea tree oil may be as effective as benzoyl peroxide (as an active ingredient) for over-the-counter creams, it takes longer to produce results. However, the same studies also showed that tea tree oil is gentler on the skin.
