Maintaining a Healthy Skin Barrier in Summer
The skin's protective barrier is the outermost layer of the skin, especially the stratum corneum, which is composed of cells surrounded by a matrix of lipids such as ceramides, cholesterol, and fatty acids. It functions to maintain cohesion and retain moisture. During the summer, the skin is subjected to additional stresses due to heat, humidity, sweating, and excessive sun exposure, leading to the erosion of this barrier, increased dryness, and irritation. Signs of this include redness, itching, and tightness. To maintain the skin barrier in summer, it is recommended to use a gentle cleanser twice daily, moisturize with products containing ceramides and glycerin, avoid over-exfoliating with peeling acids, and regularly apply a broad-spectrum sunscreen with an SPF of 30 or higher. It is also advisable not to over-wash the face or use overly active products to protect the skin barrier and prevent irritation and dryness.
