SUMMER HYDRATION AND SUN PROTECTION

An essential step, even for skin that feels comfortable.

Summer often gives the illusion of healthy skin. The complexion looks brighter, tightness feels less frequent, and the skin’s texture appears more supple. Yet behind this apparent vitality often hides a common imbalance: skin dehydration. Invisible to the naked eye, it weakens the skin’s barrier, increases sensitivity, and accelerates the appearance of signs of fatigue.

As temperatures rise, the skin produces more sebum. This natural response creates a sensation of immediate comfort, but it can be misleading. While the skin might feel soft, it can still be deeply dehydrated.

Sun exposure, frequent swimming, seawater, pool chlorine, air conditioning, and temperature changes all compromise the skin’s hydrolipidic film. Once this protective barrier is altered, water evaporates more quickly. As a result, the skin loses its ability to defend itself.

Why is hydration a fundamental need in summer?

Water is essential for the skin to function properly. It helps maintain suppleness, even tone, dermal density, and resilience against external stressors. When water is lacking, the skin’s repair and defence mechanisms slow down. Dehydrated skin is more vulnerable to stress; in summer, this vulnerability is heightened.

Water loss accelerates with UV exposure and slows down cell turnover. Combined with dehydration, this leads to changes in skin texture, and signs become apparent in early fall: dull complexion, pronounced fine lines, and uneven skin texture. Protecting hydration means taking preventive action. It helps maintain the skin’s balance despite external aggressors. It also allows the skin to recover more effectively between sun exposures and to better respond to skincare.
