Understanding Your Skin: The Epidermis

Did you know that your skin is made up of three layers? The epidermis, the outermost layer, plays a crucial role in protecting and maintaining your skin’s health. Though incredibly thin—just 0.1mm to 0.3mm—it consists of four essential layers: the stratum corneum, granular layer, basal layer, and spinous layer. On areas like the palms and soles, where skin is thickest, there’s an additional transparent layer that provides extra protection.

For a smooth, radiant complexion, these layers must function properly. The stratum corneum alone contains around 20 overlapping layers of keratinized cells, which help retain moisture. If hydration levels drop below 10%, the skin becomes dry, rough, and more prone to damage. This is why consistent, effective skincare is essential—by keeping your skin nourished and hydrated, you support its natural renewal process and maintain a healthy, youthful glow.
