I did the quick start for the rapid reveal peel, and definitely noticed brighter skin after using peels 3 days in a row. I look forward to using the peel once a week to continue my results. My skin tone was also more even. The only concern I might have is for someone with very sensitive skin. The product did feel hot on my face, but did not leave any irritation after I rinsed with cold water. I love that I only had to leave the peel on for 3-7 minutes; results were nice and quick. I received this product complimentary for testing purposes.
