Curious How To Use Ceramides For Glowing Skin? This Functional Medicine Doc Can Help

Ask a skin-care-obsessive what they yearn for every time they pat on a face oil or massage in a serum, and chances are glowing skin will be at the top of their wish list. Waking up to radiant, refreshed skin even before applying makeup is nothing short of a dream, inspiring the most adventurous of beauty gurus to slather on obscure ingredients (snail slime, blue-green algae, cork extracts, the list goes on), all in the hopes of attaining that coveted, youthful glow.

Ceramides are part of our skin's natural structure1. They are the major lipid constituent of the stratum corneum and thought to provide the barrier property of the epidermis. (Translation: They put the "barrier" in "skin barrier function.")

"They are special lipids in the outer layer of the skin, used to protect the skin and keep moisture in," says Robert Rountree, M.D., on the mindbodygreen podcast. This is exactly why, Rountree explains, these ceramides (also known as ceramosides or phytoceramides, depending on the setting) are routinely prescribed in doctors' offices or formulated in derm-favorite skin care products: "Ceramides have been used topically for a long time."

The most well-known is topicals: You most often see them formulated into serums, lotions, and creams. Yet there's another way you can reap the benefits of ceramides, that offers a perfect solution for the beauty junkie who already has an extensive skin care routine. The secret, Rountree says, is to take them in supplement form. 

"We get ceramides in our food. Cereal grains, like wheat, have ceramides in them," Rountree explains. However, you might be interested in speeding up the process. Science shows that ingesting them orally2 can offer those same skin-healing benefits as a prescription topical: "Research shows that when you take these things by mouth—and you don't need many milligrams of them—your body actually incorporates them into the skin," says Rountree. 

The short answer—it depends. If you suffer from a super-dry condition like eczema or psoriasis, you could get a prescription from your doctor and apply the formula topically. As always, it's best to consult your dermatologist before starting any treatments, especially if you suffer from a chronic skin condition. If you have run-of-the-mill dry skin, an OTC ceramide product might do the trick.

And if you just want to optimize radiant skin no matter your age, ingest ceramides orally and let the nutrient do its work from the inside out. Take it from Rountree, who states, "We can take ceramides by mouth and get that same effect."
