Hello, the mask should also be selected according to your skin quality and skin problems. The effect that suits you will double. People with different skin types are suitable for different products. Some people use it very well, while others may be average. After applying a mask on your face, you may feel spicy. It may be that the skin is too dehydrated and the permeability of the mask will be stronger. When the skin absorbs water, it may feel spicy. Maybe the product is not suitable for your allergy. Generally, we can use the mask after cleansing and toning. The function of mask is to isolate air and introduce nutrients into skin. But in fact, the skin's absorption of nutrients is limited. Within 0/5-20 minutes after the mask is applied to the face, the skin is already saturated, and what can be absorbed has been basically absorbed, but it can't be absorbed for a long time. After using the mask, it is recommended to wash it off with clear water and moisturize it with emulsion or cream. The effect will be better! It is usually enough to make a mask 2-3 times a week. I hope I can help you!
