The skin’s outermost layer (stratum corneum) acts as a protective barrier made of lipids, natural moisturizing factors, and water. When this barrier weakens:

• Moisture evaporates more easily, causing dehydration (lack of water) on top of dryness (lack of oils).
• Skin loses elasticity, appears dull, and shows more fine lines or wrinkles.
• It becomes prone to irritation, cracking, redness, and infections because external irritants/pollutants enter more easily.

Natural hydration (using ingredients that mimic or support the skin’s own processes, like plant oils, humectants from nature, and emollients) is often preferred because it replenishes without stripping the barrier further. It provides compatible lipids, antioxidants, and nutrients that synthetic options might not deliver as gently. Hydration restores water content (skin ideally holds ~30% water), while moisturization seals it in
