The Foundation Of Your Skin
Skin cells and layers.
Your skin is made up of three main layers: the epidermis, the dermis, and the hypodermis (also called subcutaneous tissue). Each plays a different role in what you see in the mirror, and a complete approach to skin health has to consider all three.
The epidermis is the outermost layer and the most important cosmetically. It gives your skin its texture, its moisture level, its colour, and the way it reflects light. It is the difference between skin that looks dull and feels rough and skin that looks radiant and feels smooth. This is the layer most skincare products target, because changes here are the fastest to become visible.
The dermis sits beneath the epidermis. It contains the collagen and elastin fibres that give your skin its structure and bounce, the fibroblasts that produce those fibres, and the network of blood vessels and lymphatic channels that feed and clear the tissue above. Real, lasting change in how your face looks requires reaching this layer too.
The hypodermis is the deepest layer — subcutaneous fat and connective tissue. It provides insulation, cushioning, and the contour of your face. Most topical treatments do not reach this layer, but its health affects how your face holds its shape.
