PIE progress with retinol

This stubborn mark was on my skin for months and did not change at all, even with BHA, AHA, tranexamic acid, sulfur, etc. The first week I applied retinol, it became at first more red and inflammed, but finally slowly faded, week after week. It's the only positive progress I noticed for now with my new retinol routine, since I am purging on the rest of my skin :( See you later with more progress. 😘
