Skincare 101: A Comprehensive Guide to Basic Skincare Knowledge

The Skin’s Structure and Functions

The Three Layers of Skin

Your skin, the largest organ of your body, consists of three primary layers:

1. Epidermis: This outermost layer acts as a protective barrier. The stratum corneum, or the topmost part of the epidermis, is crucial for maintaining skin hydration and defending against environmental stressors.
2. Dermis: Beneath the epidermis lies the dermis, home to collagen and elastin fibers. These proteins are responsible for skin’s firmness and elasticity.
3. Hypodermis: The deepest layer, composed mainly of fat cells, provides insulation and cushioning.

Key Functions of the Skin

Your skin performs several vital functions:

• Protection: It shields your body from harmful UV rays, pathogens, and physical damage.
• Regulation: Skin helps maintain body temperature and water balance.
• Sensation: It contains nerve endings that allow you to perceive touch, temperature, and pain.
