As our skin matures, it undergoes a series of natural changes that can impact its resilience and hydration levels. One of the key shifts is in the skin’s protective barrier. Over time, this barrier weakens, becoming more susceptible to damage and less efficient at keeping moisture locked in. This decline in barrier function leads to what's known as transepidermal water loss (TEWL), where essential hydration escapes from the skin’s surface, leaving it feeling dry, tight, and prone to irritation.

This weakened barrier struggles to retain moisture and becomes more vulnerable to external aggressors, such as pollutants and environmental stressors. Harmful substances can more easily penetrate the skin, leading to increased sensitivity, dullness, and visible signs of aging.
