Why does improper skin care lead to sensitive skin? -Cosmetic silicone oil manufacturer

In the process of improper skin care, the healthy skin barrier (sebum film, stratum corneum) is damaged, which leads to a decrease in skin immunity and resistance, causing skin fragility and sensitivity.
Due to damaged barrier and low immunity, sensitive skin is easily irritated. Recently, I had a consultation about red bloodshot skin. Why does it feel tingling when applying a facial mask?

1. The skin barrier has the function of absorbing and locking water. If the skin barrier is damaged, it means that the skin begins to be dehydrated. The facial mask is a closed skin care product with high water content. Therefore, when the skin is seriously dehydrated, especially now. In the dry winter, dehydrated skin suddenly receives a large amount of water, and the horny cells expand rapidly, causing the skin to tingle;
2. Some people with dry and sensitive skin usually experience skin peeling. This peeling will cause the nerve endings to be exposed, so the stimulation of some ingredients in skin care products will also cause the skin to suddenly tingle;
3. If your facial mask itself contains a lot of irritating ingredients, such as fragrances, pigments, alcohol, and a lot of preservatives, these allergenic ingredients are a source of irritation to sensitive skin, so you will also feel irritation when applying the mask. Painful and even cause skin allergies.
