Skin is the largest organ made of water, protein, fats and minerals. It is made up of 3 layers- epidermis, dermis and hypodermis.
Hypodermis:
- Innermost layer with fat and connective tissue.
- It serves as a cushion to protect all our organs from forceful external shocks.
- This is why our skin tends to shrink after losing weight & after 40 years since it losses its elasticity to bounce back to its previous state.
- Middle layer with blood vessels, nerves, hair follicles, and sweat glands.
- Contains collagen and elastin for skin strength and elasticity.
- Hyaluronic acid retains moisture.
- A person tends to have the maximum amount of collagen production at 21 years old, and thereafter 1% of collagen reduces annually, leading to decreased skin firmness and elasticity.
- Dermis plays a crucial role in supporting the production of collagen, the protein responsible for skin strength and elasticity.
- The outermost layer acts as a barrier against harmful substances.
- This is the layer where the pigment or melanin produced from the melanocytes is seen.
- Cells shed and renew through cell renewal.
- Melanocytes produce melanin for skin colour.
- Since melanocytes are more easily triggered, it's important to avoid irritants that could lead to hyperpigmentation, such as harsh acids.
