The vitamin A contained in an egg yolk, may help acne.
More Info: There are no studies directly linking egg yolk ingestion with fewer acne flare-ups, but egg yolks are a rich source of vitamin A. Healthy skin is the first step in managing your acne, and getting your recommended daily allowance of vitamin A can help you toward that goal.
Vitamin A in Egg Yolks Good for Skin
Vitamin A (retinol) plays an important role in the health of your skin. Retinol acquired through diet or supplementation supports the maintenance and health of skin and mucous membranes supporting their function as a barrier against viruses and bacteria.
Vitamin A and Acne Possible Link
One study, at least, has detected a possible link between vitamin A and acne. In a study published in the British Journal of Dermatology, researchers set out to explore the link between the levels of vitamin A and carotenoids in patients with acne vulgaris. The researchers discovered “that the mean serum concentrations of retinol and retinol-binding protein were significantly decreased in patients with acne.” [Rollman, 113]
Topical Vitamin A Good for Skin
Many over-the-counter cosmetics, particularly skin care lines, contain vitamin A as the active ingredient in the form of retinal or retinoid. The emerging anti-aging industry touts the benefits of Retin-A for treating fine lines and wrinkles, but this derivative of vitamin A has been used to treat acne for years. The prescription drug Accutane is another vitamin A derivative and is taken orally as an aggressive treatment for cystic acne. [“ACCUTANE®(isotretinoin capsules).” DailyMed]
Eggs May Cause Acne?
Ironically, in a 2006 study of 166 acne patients, more than 42% believed that eggs directly exacerbated their acne condition. The list of perceived acne causing foods also included nuts, chocolate, fried foods, cakes, coffee, and tea. [El-Akawi, 840]
