Evening Primrose Oil Help treat acne and rosacea
By working to dilute sebum, a thick oily substance that is oversecreted in some people with acne, the essential fatty acids in evening primrose oil may reduce the risk of pores becoming clogged and lesions developing. The oil's EFAs help treat rosacea by reducing inflammation, controlling cells' use of nutrients and by producing prostaglandins, which stimulate the contraction of blood vessels.
