Hi, make face washing twice a day a habit. Drink lots of water about 3 litres every day. Have coconut water daily. Apart from sugar in the tea and coffee, stomach issues are also a cause of acne. Cool down your body system with water based fruits and buttermilk. Do deep breathing exercises to clear the lungs. Have enough fibrous foods to clear your motions daily. Hope this helps.
