First retinol product

I received a sample size of this as part of my Ipsy subscription. I have never tried retinol, so i wasn’t sure what to expect. I followed instructions to use it 2 nights on 2 off at nighttime only. While it’s only been a few weeks of use, I have seen improvements in my skin already. It is noticeably more clear than when I had started, in addition to much more firm and even.
It’s extremely expensive, as I’ve seen the price online, and more difficult to get in Canada. Those are probably the only negatives. If you can find for a discount or in a beauty subscription, I’d recommend giving it a try!
