Welcome to the femaleya! Here we are going to discuss the skin layer and then the role of niacinamide in the skincare routine and why it is important for skincare.
The skin is divided into three layers;
epidermis, dermis and subcutaneous layer
1. There have three layers of skin.
2. The outermost/top layer of skin is called the epidermis.
3. It creates our skin tone and waterproof barrier.
4. It doesn’t contain any blood vessels but has many small nerve endings.
5. It consists of epithelial cells.
The thickness is different in different. For instance, thickest on palms of the hand and sole of feet- 1.5 mm but thin and delicate on eyelids.
The epidermis is arranged in 5 layers
- Stratum corneum
- Luciderm
- Granulosum
- Spinosurm
- germinativum/ basal
2. The dermis
The inner-layer/innermost of the skin is called the dermis
It is also called the true skin
It is sturdy, flexible and highly elastic
It consists of connective tissues with elastic and collagen fibres, numerous blood vessels and nerves etc..
The dermis is arranged in 2 layers
Papillary layer
Reticular layer.
3. Subcutaneous layer/ tissue
It is also called the hypodermis
The hypodermis lies below the dermis
It provides insulations and keeps your body warm
It is a thick layer of loose connective tissue and fatty tissue and this is called adipose tissues
It gives smoothness and silhouette to the body
It stores fat for use as an energy
It works as a shielding cushion for the outer skin
The hair follicle is rooted in this layer.
