What is the function of a moisturizer in skincare?

Moisturizers play a crucial role in skincare by primarily providing hydration and protection to the skin. Their main function is to maintain the skin's moisture balance, which helps keep it soft, supple, and healthy. When applied to the skin, moisturizers form a barrier that locks in water, preventing transepidermal water loss. This is essential for skin health, as dehydration can lead to dryness, irritation, and a compromised skin barrier.

In addition to hydration, moisturizers often contain beneficial ingredients that can protect the skin from environmental stressors, including pollutants and harsh weather conditions. Some moisturizers also incorporate antioxidants, vitamins, and other active ingredients that can enhance the skin's overall appearance and health.

While options like exfoliating the skin, cleansing, and treating acne are important aspects of a skincare routine, these functions are not the primary purpose of a moisturizer. Instead, moisturizers should be integrated into the skincare regimen after cleansing and any treatment steps to ensure the skin remains adequately hydrated and protected.
