Excessive hydration of the stratum corneum refers to the phenomenon where the moisture content in the stratum corneum of the skin increases abnormally, leading to changes in the skin structure. The following are direct answers in formats 1, 2, and 3:
1. Definition: Overhydration of the stratum corneum refers to the phenomenon where excessive water is directly or indirectly brought into the stratum corneum of the skin through substances that can bind with water, causing the stratum corneum to have a water content exceeding the normal range (usually considered to be between 10% and 20% in a healthy state), resulting in swelling of the stratum corneum volume and loosening of the skin structure.
2. Cause: Improper water replenishing method: excessive use of facial mask, moisturizing products, etc. causes the stratum corneum to absorb too much water. Damage to stratum corneum function: Natural moisturizing factors are reduced or dysfunctional, causing water to be unable to lock in normally within the stratum corneum, resulting in abnormal accumulation of water. Environmental factors, such as prolonged exposure to high humidity and the use of cosmetics containing alcohol, may also lead to excessive hydration of the stratum corneum.
3. Consequences and effects: Weakening of skin barrier function: After excessive water absorption by the stratum corneum, the originally sturdy "brick wall structure" becomes loose and loses strong protection, which can easily lead to skin problems. Inflammatory response: Along with the release of inflammatory factors, it may cause a series of inflammatory reactions, such as skin tightness, redness, itching, etc. Exacerbation of skin problems: Excessive hydration may also lead to excessive proliferation of sebaceous gland duct openings, increasing the risk of hair follicle blockage and subsequently causing skin problems such as acne.
To address the issue of excessive hydration of the stratum corneum, it is recommended to take appropriate skin care measures, such as choosing mild and non irritating cleansing products, streamlining skincare steps, and avoiding excessive hydration, in order to restore the normal state of the skin.
