Sometimes acne will go away once a teen reaches adulthood and other times acne can be chronic and lifelong.
But you can use Lemon Juice or Apple Cider Vinegar to treat and get rid of acne.
To get rid of acne using either Apple Cider Vinegar or lemon juice take a cotton ball and soak the cotton ball in either the lemon juice or Apple Cider Vinegar and then apply either one of those to your acne at least two times per day until the acne goes away.
Apply either the Apple Cider Vinegar or Lemon Juice to the acne and let it dry and then wash your face off.
Applying the Apple Cider Vinegar or Lemon Juice to your acne you should see the acne start to go away and fade over a period of 1 to 3 months.
The time it takes to get rid of the acne will depend on how severe the acne is and how often you treat it.
