When we look at the description of skincare products, we always see the words ‘increase or improve skin moisture barrier’. So What is skin moisture barrier?
Let’s briefly talk about our skin anotomy and its function first. The normal skin consists three layers:
- The outmost layer is the epidermis, which provides a waterproof barrier and creates our skin tone, so it’s our skin’s protective layer.
- The middle layer is the dermis, beneath the epidermis. It contains tough connective tissue, hair follicles, and sweat glands.
- The deeper layer is the subcutaneous tissue (hypodermis). It is made of fat and connective tissue.
The Epidermal Barrier
The epidermis is a core component of our skin and plays a vital role in healthy and compromised skin. According to research, the epidermis and hypodermis work together to act as epidermal barrier for specific diverse function. These include include maintenance of water content and balance , prevention and responses to invasion by microbial organisms and antigens, reduction of the effects of ultraviolet (UV) light exposure , and mitigation of the effects of oxidative stresses.
‘The Epidermal Barrier functions are dynamic and work collectively to maintain healthy skin, characterized by invisible desquamation, smooth texture, elasticity, and ability to respond to shearing forces without rigidity and microfissuring’
The Importance of Epidermis
Although many of the major activities of barrier maintenance and repair occur within the SC, the entire epidermis contributes to the EB (1). If our skin moisture barrier is shattered, our skin loses its moisture and becomes prone to dryniess and sensitivity. However, a strong skin moisturer barrier can absorb and retain sufficient moisture, thereby keep the skin in a healthy state.
In order to achieve healthy skin, we need to protect the skin moisture barrier that is easily damaged by various environmental factors and external irritants.
We have collected of products to improve our skin moisture barrier, such as
