How Fall Changes Your Skin (And What to Switch in Your Routine)

The transition into fall isn't just a temperature change. Lower humidity, cooler air and more time indoors with forced-air heat all affect how your skin behaves, and for people with sensitive or reactive skin, this is often the time of year when everything feels worse.

Here's what's happening and where soap fits in.

What Changes in Fall

Your skin's moisture barrier, the outermost layer of skin, works harder in dry conditions to hold onto water. When humidity drops significantly, moisture evaporates from the skin's surface faster, and the barrier has to compensate.

For skin with a strong barrier, this is mostly a background process. For skin that's already reactive or prone to dryness, the drop in humidity can leave it feeling tight, rough and uncomfortable.

Where Soap Comes In

Most people don't think about their soap when their skin gets worse in fall, but it's worth reconsidering.

Cleansing removes not just dirt but also some of the lipids (fats) that make up the moisture barrier. A bar made with more stripping oils, particularly those high in lauric acid, like coconut oil-based soaps, can take more of that barrier with it than one made with more skin-compatible oils.

Tallow, in particular, has a fatty acid profile that's similar to human sebum, the skin's natural protective oil. Tallow-based soaps tend to feel different on skin, especially in dry conditions, because they cleanse without removing as much of what the barrier needs.

What to Consider Switching

If your skin typically gets drier or harder to manage in fall and winter, the bar soap you're using is a reasonable place to look. Specifically:

• If you're currently using a coconut oil-heavy soap (check for "sodium cocoate" high on the ingredient list), switching to a tallow-based or coconut-free formula for the colder months is worth trying
• If you're using synthetic fragrance in your soap, that's another common culprit worth removing when your skin is under more stress

The coconut-free collection at Sea Spray Soap was built for exactly this situation. The Coconut-Free Calamine Soap Bar, with its kaolin clay, calamine and tallow base, is the one we'd point to if your skin feels worse in the colder months.

The Rest of the Fall Skin Routine

Soap is the start, not the end. Moisturizing right after washing, while skin is still slightly damp, helps hold in hydration. A humidifier in the bedroom makes a noticeable difference if you're running forced-air heat.

But the cleanser is worth getting right first. If you're stripping your skin every time you wash and then trying to make up for it with moisturizer, you're working harder than you need to.
