From south to north in summer, my face is dry, itchy, oily and red. What should we do? What drugs and skin care products can be improved?

The weather in the north is hot and dry. First of all, you are not acclimatized, and your body may be uncomfortable. Eat more fruits and drink more water, and be sure to apply a mask. This is the fastest and best way to replenish water to the skin. Don't use drugs casually, especially on your face. Just apply the mask for three days. Then apply it every three days.
