It's very hot and my face is very red.

Hello, your skin should be allergic. There are symptoms of red blood. Wash your face often with cold water, exercise your skin and enhance your skin's tolerance. Try to avoid entering the cold and hot environment, so that the skin has an adaptation process, so as not to aggravate the red blood. Try not to use cosmetics containing heavy metals to avoid pigment deposition and toxin residue on the epidermis. Massage the red bloodshot parts frequently to promote blood flow and help to enhance the elasticity of capillaries. If the symptoms do not improve, it is recommended to go to the hospital for laser treatment. Both bloodshot and acne can be cured. Pay attention to the usual aftercare.
