You've already awarded Best Answer, but you haven't yet heard the real best answer. IDC about that. Here's your FYI:
Your skin is easily scarred and likely slow to heal AND you have acne bc of a hormone imbalance caused by the overconsumption of fructose via sugar, HFCS, honey, nectar, juice, molasses, maple syrup and white flour products (most breads, crackers and pastas. )
Add in a little hormonal upset from puberty, and your skin is slightly worse, but puberty is not the primary cause.
Too much fructose is.
So much more...
