No Joke: Volcanic Ash Is a Magical Skin-Clearing Ingredient

Dermatologists weigh in on its oil-clearing properties.

When you learn that one of the latest need-to-know skincare ingredients hails from the fires of a volcano, you might think the quest for eternal youth has finally gone too far. But volcanic ash—yes, like actually ash from an actual volcano—has been popping up in our creams, masks, and cleansers for a bit, and for good reason. While the name may be off-putting and raise questions about how it's sourced, volcanic ash boasts a bevy of skin benefits. Think of volcanic ash as the marginally-gentler-but-equally-effective cousin to clay and mud.

Main benefits: Clarifying, antibacterial, reduces oxidation

Who should use it: In general, people with acneic, oily skin.

How often can you use it?: Try not to use it more than once every few days, as it can be drying.

What is Volcanic Ash?

According to National Geographic, in simplest terms, "Volcanic ash is a mixture of rock, mineral, and glass particles expelled from a volcano during a volcanic eruption." As opposed to lava or volcanic rock, however, volcanic ash isn't something that flows from volcanoes. Instead, it's expelled across large distances along with water and gas. Volcanic ash has actually created plenty of problems for people over the years—from killing crops to delaying and cancelling flights. However, its unique structure makes it a fantastic ingredient for skincare.

Volcanic ash particles are tiny and highly porous, which means they're incredibly absorbent. This works very well for cleaning up liquids; in the beauty market, this means they're specifically great for clearing off the stubborn oil and sebum that sit on your face during the day. It also means the ash is helpful in clearing up any less-than-natural things that may be residing on your face like pollution and extra makeup.

Benefits of Volcanic Ash for Skin

Joanna Vargas, celebrity facialist and founder of Joanna Vargas Salons and Skin Care, gave us the lowdown on how volcanic ash works for skin: "Volcanic ash is a physical exfoliant that draws out impurities, dirt and oil from your pores, which allows products to penetrate properly. It’s also an anti-inflammatory and contains calcium potassium, which is essential to stimulating the lymphatic system. It’s great for both the body and face because it’s not hard for most skin types to tolerate. It’s very gentle, yet effective."

"Volcanic ash is extremely rich in minerals and has antiseptic, antibacterial, and antioxidant properties," echoes Sonya Dakar, celebrity esthetician and founder and CEO of Sonya Dakar Skincare and Skin Clinic. "So it works really well to not only clear blemishes but heal the inflamed, irritated skin." Basically, if your skin feels polluted—for whatever reason—volcanic ash is a pretty good ingredient to turn to.

Side Effects of Volcanic Ash

Volcanic ash has the same major side effect as pretty much any volcanic or mud-based product: it's drying. As in, if it's not mixed with the right ingredients, it can cause some seriously intense facial irritation. Skin isn't meant to be totally oil-free—that's why oil cleansers exist and some people with oily skin actually find it helps when they add more oil instead of trying to dry it off. Try to make sure the volcanic ash-based product you're using has a lot of hydrating ingredients to balance it out.

How to Use It

"Volcanic ash has antioxidant and antibacterial properties," Adarsh Vijay Mudgil, MD, founder of Mudgil Dermatology in NYC reiterates. However, he suggests a way to use them: "These are best used as a mask, to help give the skin some 'pop.'" Because of its drying properties, volcanic ash isn't an ingredient you particularly want to leave on your face for an extended period of time unless your skin is extremely oily. However, it makes for a fantastic treatment.
