Try adding slices of fruits and veggies, like grapefruit, orange, and cucumbers, to make your water more refreshing. Getting all the right nutrients in your diet is an important step to creating beautiful skin. Make sure to include fruits and veggies at every meal.

Avoid foods that are high in fats, sugars, and processed carbs, like chips, sodas, candy, fast food, and fried foods.

Take a moment to find a quiet place. Close your eyes, and focus on your breathing. Breathe in slowly, counting to 4 in your head. Then, breathe out, counting to 4 again. Keep it up until you feel yourself calm down. Sleep is essential for a lot of different reasons, but it can actually affect your skin health, as well.
