Damage to the skin barrier generally refers to the destruction of the physical barrier of the skin, so that the skin’s defense function is weakened, thus causing abnormal reactions and sensitive state of the skin.
Skin barrier generally refers to the physical barrier of the skin, which is mainly composed of sebaceous membrane, stratum corneum keratin, lipids, mucopolysaccharides, etc., and has certain functions of resisting the entry of external harmful substances, moisturizing and anti-inflammatory.
When the skin barrier is damaged, its defense function will decline, easy to cause skin dryness, aging and other conditions, but also prone to inflammatory reactions, such as atopic dermatitis, eczema, psoriasis, ichthyosis, solar dermatitis, irritant dermatitis, acne, seborrheic dermatitis and so on.
It is recommended to protect the skin reasonably on a daily basis, and not to overuse skin care products, so as not to make the skin too sensitive and more susceptible to damage.
