Skin barrier and moisturizing principle
The skin barrier is mainly composed of stratum corneum cells and intercellular lipids, and its function is to prevent water loss and resist external stimuli. Under normal circumstances, the skin maintains a certain moisture content to maintain the integrity of the barrier. Handwashing Fluid removes oil and dirt on the skin surface during the cleaning process, and may also disrupt the skin's moisturizing balance. Handwashing Fluid with good moisturizing properties can replenish the moisture lost by the skin during the cleaning process and form a moisturizing film on the skin surface. For example, some Handwashing Fluids are added with moisturizing ingredients such as glycerin and hyaluronic acid. These ingredients can absorb moisture in the air and lock it, keeping the skin hydrated, thereby helping to maintain the stability of the skin barrier function.
The role of moisturizing in barrier repair
When the skin barrier is damaged, moisture is more likely to be lost and external irritants are more likely to invade. Handwashing Fluid with good moisturizing properties helps repair damaged skin barriers. By continuously providing moisture to the skin, it can promote the normal metabolism and regeneration of stratum corneum cells and restore the synthesis of intercellular lipids to normal. For example, when the skin is slightly dry and flaky due to frequent hand washing or contact with irritants, using a handwashing fluid with good moisturizing properties can relieve these symptoms, allowing the skin to gradually restore elasticity and luster, enhance the skin's own defense capabilities, and reduce skin problems caused by barrier damage, such as itching, redness, and swelling.
Different effects of different moisturizing ingredients
There are many types of moisturizing ingredients in handwashing fluids, and their effects on skin barrier function are also different. Glycerin is a common moisturizer that can increase the water content of the skin's stratum corneum and is relatively affordable. Ceramide, on the other hand, focuses more on repairing damaged intercellular lipids and enhancing the structural integrity of the skin barrier. Hyaluronic acid has strong water absorption, which can replenish a large amount of moisture to the skin and form a moisturizing gel, keeping the skin moist for a long time. Different handwashing fluids may choose different combinations of moisturizing ingredients according to the target audience and product positioning to achieve the best moisturizing and barrier maintenance effects. For example, Handwashing Fluid for dry skin may add higher concentrations of glycerin and hyaluronic acid, while Handwashing Fluid with repair function will focus on adding ingredients such as ceramide.
Long-term use effects and precautions
Long-term use of Handwashing Fluid with good moisturizing properties has a positive cumulative effect on skin barrier function. It can keep the skin in a relatively healthy and stable state, reducing problems such as skin aging and increased sensitivity caused by daily cleaning. However, even Handwashing Fluid with good moisturizing properties should not be overused. Excessive hand washing will still disrupt the natural oil balance of the skin, and some people may be allergic to certain moisturizing ingredients in Handwashing Fluid. Therefore, when choosing Handwashing Fluid, you should choose it reasonably according to your skin type and needs, and pay attention to the correct hand washing method and frequency to give full play to the beneficial effect of Handwashing Fluid's moisturizing properties on skin barrier function and avoid negative effects caused by improper use.
