Holy grail for my combo skin

I have been using this product for almost two years, I probably went through four bottles already. Since I started using it, it took about two weeks to already see the difference. I have combination skin with visible pores, blackheads, hormonal acne and occasional acne caused by pollution/diet choices. I no longer had issues with deep skin acne and my skin texture improved. I don’t have sensitive skin so I didn’t have a period of getting used to the product but since it is packed with acids, someone with more sensitive skin should be more cautious and probably use the product only a few times in the week. I use it each night with the rest of my routine. If there are no wounds from acne picking for example, there should not be a burning sensation when using the product.
