One of those steps involves improper shedding of skin cells. Vitamin A can improve how the pores remove dead skin cells and this lowers the chances of developing clogged pores that provoke surplus growth of the acne activating bacteria Propionibactium acnes. Moreover, a report in the Proceedings of the Nutrition Society have found that a vitamin A deficiency can induce inflammation and escalate existing inflammatory states. Clinical research supported this finding. For example, report in Clinical & Experimental Dermatology detected a direct link between blood levels of vitamin A and acne. In this investigation, researchers compared the blood levels of vitamins A in 100 newly diagnosed, yet untreated acne patients to 100 age-matched, healthy volunteers without acne. Overall, the healthy, acne free group had higher amounts of vitamin A in their circulatory system than the acne sufferer group. Based on these findings, investigators concluded that low vitamin A blood levels could cause or worsen an acne outbreak. Years earlier, an investigation in the British Journal of Dermatology found that low vitamin A blood levels corresponded to heightened levels of severe, cystic acne in male volunteers.

However, for individuals whose health conditions, lifestyle choices or medications hamper their bodies' ability to receive or absorb proper amounts of vitamin A from foods, a supplement is in order.
