Protective masks in frosty weather need to be changed more often than in the hot season. According to RIA Novosti, this was stated by Nikolai Arsentyev, a dermatologist and candidate of medical sciences, head of the treatment and diagnostics department of the Clinic of Dermatology and Venereal Diseases at the Sechenov University in Russia.
According to him, the face should be allowed to breathe once every 30 minutes. The expert explained that wearing a mask in winter has a "greenhouse" effect, which has a detrimental effect on the condition of the skin. Thus, due to the temperature difference between breathing and outside air, condensation accumulates in the mask. Arsentyev advised to consult a doctor if skin problems occur. He also advised not to buy lotions from pharmacies without consulting a doctor.
