There is little red dot in winter or when the weather is cold. It feels as uncomfortable as goose bumps. Not when the weather is warm. What's going on? What should I do?

Because the temperature is low in winter, the self-protection of the human body shrinks the pores on the skin, thus reducing the heat emission and maintaining the normal body temperature. The acne you touch is the tightening of pores and hair, which is the sebum and metabolites secreted by the skin. The skin is dry at this time. It is suggested that you slightly extend the washing or soaking time in the bath, so that the pores of the skin can be fully opened, and then wash with a mild bath. Apply moisturizing body lotion after drying, and keep warm on weekdays. Generally, please follow the following steps. Just try it. I wish you a happy New Year!
