Stop using soap on face. Instead take a spoon of milk, add a pinch of turmeric (haldi). Mix n apply on face with the help of cotton. Leave for a few minutes then wash off. Apply moisturizer like coconut oil.
Simple Honey Mask--Before applying this mask, rinse your face with warm water to open up pores. Then apply honey and leave it on the skin for 30 minutes. Rinse the honey off with warm water; then rinse again with cold water to close the pores.
