Because of improper skin care, healthy skin barriers (sebum membranes, cuticles) are damaged, resulting in a decrease in skin immunity and resistance, resulting in fragile and sensitive skin.

Sensitive skin is vulnerable to irritation due to damaged barriers and low immunity. Recently, there have been consultations on red blood skin, why do I feel tingling when applying mask?

1. The skin barrier has the function of absorbing and retaining water. If the skin barrier is damaged, it means that the skin is starting to be dehydrated, and the mask is a closed skincare product with high water content. Therefore, when the skin is severely dehydrated, especially now In dry winter, the dehydrated skin suddenly receives a lot of water, and the keratinocytes expand rapidly, and the skin may be stinging;

2. A part of dry and sensitive skin usually has skin peeling. This peeling will cause nerve endings to be exposed to the outside, so being stimulated by some ingredients in skin care products will also cause sudden skin tingling;

3. If your mask itself contains a lot of irritating ingredients, such as flavor, pigment, alcohol, and a lot of preservatives, these sensitizing ingredients are a source of irritation for sensitive skin, so you will feel skin irritation when applying the mask Pain can even cause skin irritation.
