Hydration & Barrier
Skin barrier damage occurs when transepidermal water loss (TEWL) rises because of abnormal stratum corneum lipids (ceramides, cholesterol, fatty acids) and a drop in natural moisturizing factor (NMF). Dryness, tightness, flaking and sensitivity appear, and the skin becomes vulnerable to external irritants.
Skin Concern Analysis
Skin barrier damage occurs when transepidermal water loss (TEWL) rises because of abnormal stratum corneum lipids (ceramides, cholesterol, fatty acids) and a drop in natural moisturizing factor (NMF). Dryness, tightness, flaking and sensitivity appear, and the skin becomes vulnerable to external irritants.
Spicule Solution
The fine physical stimulation of spicules induces stratum corneum remodeling, and high-molecular moisturizing ingredients such as hyaluronic acid and ceramides are delivered deep into the barrier through the microchannels.
