Scientific Care for Dry Skin: Complete Guide to Deep Hydration and Barrier Repair

Dry skin is one of the most common skin types, characterized by stratum corneum water content below 10%, accompanied by tightness, dryness, peeling, and susceptibility to fine lines. Many people believe that dry skin can be solved simply by "hydrating more," but in reality, dry skin care requires deeper understanding and more systematic approaches. This article will comprehensively analyze the causes, characteristics, and care strategies of dry skin from a scientific perspective, helping you establish a correct dry skin care system.

Scientific Definition and Classification of Dry Skin

🔬 Physiological Characteristics of Dry Skin

Water Content Standards:

• Normal Skin: Stratum corneum water content 20-30%
