Why Does Skin Feel More Oily During Rainy Weather? The Science Explained

A rainy day can leave your skin feeling strangely sticky even when you have not done anything particularly strenuous. Your face may look shinier, your forehead can feel greasy and skincare products that normally feel comfortable suddenly seem heavy. It is easy to blame the rain itself, but the real culprit is usually humidity. When the air contains a lot of moisture, sweat evaporates less efficiently and the skin's natural oils can remain on its surface for longer. Hormones, genetics and skincare habits also influence how oily someone becomes. So why does rainy weather change the way your skin feels?
