If your face is always red and hot, consider that it may be an irritant dermatitis formed after the skin stratum corneum is damaged. The skin’s own resistance decreases when it is exposed to certain external stimuli, and its ability to adapt is also weakened, resulting in a red and hot state. Local capillaries increase in blood flow rate within a short period of time, there will also be obvious red blood, and in severe cases, there will be stinging, itching and many other symptoms. In addition, the frequent use of glucocorticoid topical creams on the face can also lead to an increase in the concentration of hormones on the face, stimulating the face and triggering hormone-dependent dermatitis. In addition to redness and burning, hormone dependent dermatitis can also cause pus, dripping and even acne, so you need to choose to restore the thickness of the stratum corneum, and it is recommended to apply hyaluronic acid gel or humanoid collagen milk.
