Many people have dense red pimples on their arms and legs.
Seeing them, you might be tempted to squeeze them with your hands.
But it’s not only prone to inflammation,can also cause pigmentation.
This skin disease is keratosis pilaris.
So what is the reason for it?
Our skin is like a tough outer wall, retains moisture in the body.
It can also prevent the invasion of external germs.
The basal layer of the skin is constantly dividing keratinocytes.
In daily life, many keratinocytes on the surface of our skin will be rubbed off.
So the basal layer of the epidermis will always split it to replenish the stratum corneum.
In normal people skin, the process of epidermal keratosis is normal.
Make as many cuticles as you need.
But people with keratosis pilaris have too much splitting of the basal layer of the skin.
Keratinocytes keep pushing up.
These extra keratinocytes will accumulate at the hair follicle orifice.
Make fine hair unable to grow normally, curled at the hair follicle orifice.
Long-term closure of hair follicle orifice to form protrusion.
And because these cells divide so rapidly.
Does not form a stratum corneum with good barrier function.
Therefore, it may cause dry skin and decrease of barrier function.
Keratosis pilaris is closely related to heredity.
It is also related to vitamin deficiency, endocrine and other factors.
According to the statistics, about half of the population has keratosis pilaris.
With age, keratosis pilaris may gradually improve.
But some people even in old age.
Keratosis pilaris will not improve forever.
So what can we do to improve?
1. Do not take too long in the bath.
2. Do not use too hot water.
3. Do not use strong oil removal and do not use irritating bath products, otherwise the body’s moisturizing oil will be washed away too much.
4. Be sure to apply body lotion in time after bathing.
5.The parts with keratosis pilaris should be protected from sunscreen to prevent sun damage to the skin.
