I discovered this by accident and its not really a peel but a really good exfoliation. I have been trying to get rid of blackheads by steaming my face and then using baking soda paste all over. One day when it had dried, I dabbed lemon juice on to get it off. It bubbles and fizzes and get really warm for a few seconds. I keep doing it till the paste is gone then I wash my face. My skin feels pretty smooth and soft afterwards.
