Wearing masks is essential for preventing COVID-19 but the longer use of masks can also lead to acne among some people because of the heat and sweat. Dr Sachin Dhawan, Senior Consultant Dermatologist, Fortis Hospital, Gurgaon and Co-founder, Skin n Smiles says that washing face with cold water can help soothe acne. He also suggests wearing a soft cotton mask underneath the N-95 mask that is usually rough.
