Why Does Skin Feel Dry When Traveling by the Sea? | Coastal Travel Popular Science

Many people find that their skin becomes dry, tight, and even peels after traveling by the sea. In fact, this is not due to sun exposure, but caused by the special environment by the sea, which is also a common popular science knowledge for coastal travel. There are two core reasons for dry skin by the sea: first, the osmotic pressure of seawater. Seawater contains a lot of salt. When the skin comes into contact with seawater, the salt concentration in seawater is higher than that in skin cells, which causes skin cells to lose water, resulting in dryness and tightness; second, the wind by the sea. The wind by the sea is strong, which accelerates the evaporation of water on the skin surface, making the skin lose water and become dry. In addition, the ultraviolet radiation by the sea is extremely strong, which can damage the skin barrier and further aggravate skin dryness and peeling. Therefore, it is very important to do a good job in skin care when traveling by the sea: after touching seawater, rinse the skin with clean water in time to remove surface salt; apply body lotion and sunscreen with good moisturizing effect to not only supplement skin moisture but also resist ultraviolet damage; at the same time, drink plenty of water to supplement body moisture and avoid skin dryness caused by body water shortage. Understanding these knowledge points allows you to better protect your skin while enjoying the coastal scenery and have a more comfortable travel experience.
