Many people find that their skin becomes red, stings, or feels itchy more easily than usual during the summer. Strong UV rays, high temperatures, sweat, sebum, and air-conditioning all affect the skin at the same time, so people with naturally sensitive skin may experience discomfort even from minor irritation.
Sensitive skin is also often associated with a weakened skin barrier, which can make it react quickly to changes in the external environment. During the summer, it is important to cool the skin and reduce breakouts, but it is even more important to focus on soothing care and barrier recovery so that the skin is exposed to less irritation.

Why does skin become more sensitive in summer?
As temperatures rise in summer, the skin temperature can also increase easily. When the skin temperature rises, redness may become more pronounced and the skin may feel hot. Increased sweat and sebum can make the skin’s surface feel sticky and more sensitive to irritation. When UV exposure is added to this, the skin can become tired and sensitive more easily.
Indoors, air-conditioning can also cause the skin to lose moisture quickly. Even if the skin looks shiny on the surface, it may be dry and tight underneath, a condition often referred to as internal dryness. If this state continues repeatedly, the skin barrier may weaken, causing stinging from cosmetics, cleansing, or friction from a mask.

Why is soothing care important for sensitive skin?
When irritation accumulates, sensitive skin may develop redness, stinging, dryness, itching, and breakouts at the same time. At such times, excessive skin care, harsh exfoliation, over-cleansing, or irritating products may further weaken the skin barrier. Therefore, when the skin becomes sensitive, it is important to soothe it first and give it time to recover.
Soothing care does not simply mean calming redness. It is a process that helps the skin retain moisture and creates an environment in which it can be protected from external irritation. Once the skin has stabilized, treatments for brightening, firmness, pores, and acne can also be continued with less burden on the skin.

How should sensitive skin be cared for during summer?
First, cleansing should be gentle. Using a strong cleanser frequently just because there is a lot of sweat and sebum can damage the skin barrier. It is important to use a mild cleanser suited to your skin type in the morning and evening, then apply a lightweight moisturizer afterward to prevent the skin from becoming dry.
Sun protection is also essential. However, if you have sensitive skin, it is better to choose a product that causes little irritation and places less strain on the skin. If your skin feels heated after going outdoors, using a soothing or moisturizing product kept cool may help reduce the sensation of heat. However, if the skin is severely red, stings, or continues to itch, it is better to seek medical attention rather than relying solely on self-care.

Sensitive skin can easily become unstable in summer as multiple irritants overlap, including heat, UV rays, sweat, sebum, and air-conditioning. Rather than trying to address all skin concerns at once, it is better to soothe the skin first and focus on restoring the skin barrier.
If redness, stinging, itching, dryness, or breakouts recur frequently, it is important to accurately check your current skin condition through a consultation with a board-certified dermatologist. Based on the dermatologist’s diagnosis, gradually proceeding with soothing care, barrier recovery treatment, and procedures suited to your skin condition may help you maintain more comfortable and healthy-looking skin during the summer.
