I tried retinol for the first time, and it noticeably reduced my pores! If you can actually feel the difference, that's a sign it's working well, right? I was a bit nervous because I'd heard retinol products can be harsh, but this serum-type formula was surprisingly gentle on my cheeks, despite its high retinol content.
However, I wanted to tackle some eye wrinkles, so I applied it under my eyes. By evening, the area had darkened as if I'd been burned! I'd recommend avoiding the eye and mouth areas when using this product.
