Well if you want to go the natural route you can make a paste of honey, vinegar, and banana. Apply it to the face nightly for 15 minutes then wash with warm water. You can also just start washing your face with coconut oil. It will not make the acne worse. Garlic can be rubbed on acne and usually shows signs of improvement within 3 days. Just be careful not to leave on the skin for too long. Tea tree oil is a great option. If the acne leaves dark spots behind you can use lemon or lime to lighten those up. If you choose not to go the natural route you can use a glycolic peel on your face. The 20% is the starting strength and you work your way up.
