Ayurveda describes seven separate layers of the skin Each layer has its own structure and function. The layers are designed so that each layer provides support to the layers above it.
The skin as a whole is able to perform its overall functions effectively when all seven layers are healthy.
Factors which determine skin health and youthfulness include:
1. proper moisture balance
2. effective functioning of the metabolic mechanisms that coordinate all the various chemical and hormonal reactions of the skin
3. efficient circulation of blood and nutrients to the different layers of the skin.
Layer 1, the outermost layer, is the source of complexion and reflects the quality of the nutrient fluid and whether the physiology as a whole is balanced or imbalanced. Layer 1 indicates whether there is inner health or some disorder.
Layer 2 indicates the quality of the blood. Impurities) in the blood accentuates sensitivity to the sun.
Layer 3 provides balance to skin colour, lightening the darker colours of the inner layers.
Layer 4 nurtures the upper layers of the skin. It supports the immune system and helps the skin perform its function of being a barrier. Skin infections reflect an imbalance in this layer.
