Is there a connection between diet and the occurrence of milia?

The milium grains are microcysts resulting from the accumulation of layers of keratin trapped beneath the skin's surface layer (horny layer). Despite an origin that is not well understood, various information circulates on the Internet regarding a possible association between milium grains and diet.

high cholesterol level , encouraged by the consumption of overly sweet, fried, spicy, overly salty foods, and simply foods high in cholesterol. Others more specifically mention a skin fat imbalance as being responsible , due to an unbalanced diet between omega-3 and omega-6. Indeed, many people would have a diet containing an excessive amount of omega-6 (pro-inflammatory) and an insufficient amount of omega-3 (anti-inflammatory). This imbalance is what would cause milia. Finally, some sites mention a vitamin A deficiency , and several of them more broadly cite a disrupted diet advising to eat more fruits and vegetables for example.

After thorough investigation, we have found no tangible scientific evidence to support these claims. We therefore conclude that it is impossible to assert a link between diet and milia. Indeed, certain factors are presumed to contribute to the appearance of milia, including heredity, spontaneous occurrence due to blocked hair follicles, trauma, excessive exposure to UV rays and long-term application of topical corticosteroids. The only association found in studies is that which links milia to dermatological diseases, known as genodermatoses.

It is therefore important to note thatno link has been proven between milia and diet.
