Effects of volcanic ash on the skin's surface
Jakarta (ANTARA) - Skin and venereology specialist Dr. Arini Astasari Widodo, SM, SpDVE, has explained that when volcanic ash settles on the skin, it can cause dryness, a stinging or burning sensation, itching, and redness or irritant dermatitis.
“In most people, brief contact with ash does not cause serious skin problems,” Arini said when contacted by ANTARA in Jakarta on Monday.
A member of the Indonesian Society of Dermatology, Venereology and Aesthetics (Perdoski), she noted that people who already have sensitive skin, atopic dermatitis or eczema, rosacea, or a compromised skin barrier — for instance after laser treatment or peeling — need to be more careful, as their skin is more prone to irritation.
“Ash particles can also be abrasive. That is why one should avoid rubbing or wiping ash that is still dry on the surface of the skin, as the friction can actually increase irritation,” said the Harvard University graduate.
If possible, first remove clothing that has been heavily exposed to ash. Rinse the skin with clean running water so that the particles are lifted off without much friction.
She also recommended bathing with cool or lukewarm water and a gentle cleanser, and avoiding scrubs, rough sponges, or rubbing the skin too hard.
If the face becomes irritated, it is advisable to temporarily reduce the use of active ingredients that could make the skin even more sensitive, such as retinoids, AHA/BHA, peels or scrubs, until the skin calms down.
Arini further stressed that when it comes to prevention, physical protection is more important than medication. People can use a simple moisturiser, free of fragrance, that supports the skin barrier — for example, one containing ceramides, glycerin or other humectants and emollients.
She also noted that the eruption of Mount Anak Krakatau in the waters of the Sunda Strait, and the spread of its volcanic ash, should be heeded. The public has been urged not to panic, although in terms of skin health, volcanic ash is different from ordinary everyday dust.
Arini explained that volcanic ash consists of very fine rock and mineral particles, some of which have abrasive surfaces, and fresh ash can also carry acidic components.
“That is why the most important principle is to reduce direct contact with ash, especially when ash concentrations in the air are high. The impact on the respiratory tract and eyes is generally the main concern, but the skin can also become irritated,” she added.
