How Wildfire Affects Your Skin

Wildfire smoke is more than just a respiratory concern. It can affect your skin, too, even when the fire is many miles away.

For those of us who love life outdoors, smoky skies are a frustrating reminder that sometimes staying inside is the better choice. Researchers are also learning more about the relationship between wildfire smoke and skin irritation. A study published in 2021 examined the 2018 California Camp Fire and found an association between wildfire air pollution and increased health care visits for atopic dermatitis and itching.

How Wildfire Smoke Affects the Skin

Wildfire smoke contains a mixture of particles and gases. Particulate matter is a major concern. PM2.5 refers to fine particles measuring 2.5 micrometers or less in diameter. A 2025 review, Wildfire Exposure and Respiratory Health: A Comprehensive Review of Emerging Evidence, explains that inhaled fine and ultrafine particles can reach the lower airways and the lungs’ tiny air sacs, where they may trigger oxidative stress and inflammation. This is evidence about inhalation, rather than penetration through skin.

Larger particles can settle on the skin’s surface and may contribute to irritation or allergic reactions in susceptible individuals.

Air-pollution research links exposure to oxidative stress, irritation, and changes in the skin barrier. Oxidative stress occurs when reactive molecules overwhelm the skin’s antioxidant defenses. These molecules can damage skin lipids, proteins, and other cellular components.

Research on air pollution also explores its relationship with uneven pigmentation, wrinkles, and changes in the skin’s microbiome, the community of microorganisms that lives on its surface. These findings should not be taken to mean that every brief smoke exposure causes all of these effects.

One mechanism under investigation involves matrix metalloproteinases, or MMPs. These enzymes help break down proteins such as collagen. Changes in their activity are one way researchers study the relationship between pollution and skin aging.

Why the Skin Barrier Matters

Your skin barrier helps keep moisture in and unwanted substances out. When that barrier is disrupted, skin may feel dry, tight, or more easily irritated. Gentle cleansing and moisturizing can help care for the skin without adding unnecessary stress.

Skincare is not a substitute for reducing smoke exposure. A cream cannot make polluted air safe or protect your lungs.

Understanding Air Quality Reports

The Air Quality Index, or AQI, helps you understand outdoor air pollution and the precautions recommended for current conditions. Check a current local report rather than relying on yesterday’s smoky sky or an old reading. The USDA Forest Service’s explanation of smoke and health provides background on why fine particles matter.

Simple Skincare During Wildfire Season

Reduce Smoke Exposure First

Limit time outdoors when air-quality guidance recommends it. We really hate to give that advice. Follow local public-health recommendations about outdoor activity, indoor air, and appropriate respiratory protection. Do not assume that any face covering provides protection from fine smoke particles.

Cleanse Gently

After being outdoors in smoky conditions, gently wash away surface buildup. Avoid scrubbing or repeatedly washing skin that already feels irritated. An oil cleanser followed by a gentle, creamy cleanser can be an option when removing sunscreen or makeup, but a double cleanse is not necessary every time.

Follow With Moisturizer

Apply a moisturizer after cleansing to help reduce moisture loss and keep skin feeling soft and comfortable. Keep the routine simple, especially if your skin feels sensitive. More products and more cleansing are not always better.

Keep Antioxidants in Perspective

Antioxidants such as vitamins C and E are used in skincare to help address oxidative stress. An antioxidant-rich moisturizer can be part of your regular routine, but it should not be described as a shield against smoke or a way to prevent pollution-related illness. A varied diet that includes fruits and vegetables also supports overall nutrition.

If irritation persists, or an existing skin condition worsens, seek advice from a health care professional.

Products for a Simple Routine

For cleansing, explore Yarrow Oil Cleanser and Meadow Mist Face Cleanser. Choose the cleansing approach that suits your skin and what you need to remove.

For moisturizing, Springtide Gold Face Cream is an option for your facial skincare routine. These products are for cleansing and moisturizing, not a replacement for smoke-exposure precautions.

We hope we don’t have to think about skin concerns caused by wildfires. But when smoke reaches our communities, a little knowledge and a gentle routine can help us care for ourselves. We also acknowledge, and are saddened by, the losses so many people have experienced because of wildfires.
