### ⭐⭐⭐⭐⭐ Great Skin Care

### ⭐⭐⭐⭐⭐ It’s oily, but…
*by A***N on April 18, 2024*

It’s a fantastic product. Compared to other retinols on the market, this has only one questionable ingredient that has the potential to be an endocrine disruptor, but more science research is needed on the matter. This is meant to be the last step in your skincare routine without a moisturizer. I tried three different moisturizers after applying this retinol, but they all pilled. I use the retinol oil as my last step, and my skin feels hydrated, so there was no need for me to apply a moisturizer afterwards. I love that this retinol is powerful but also gentle on my skin. I experienced drying the first time I used this, but I also used it three days in a row. I learned afterward that you need to start slow, and eventually my skin barrier worked itself out. I apply this a few hours before bed so it has time to absorb into my skin. I also apply the COSRX Snail Mucin 96 essence before hand. If you have never used retinol, I would suggest starting with their 0.1% cream and slowly building yourself up to this product. I didn’t experience any skin purging like others have. To avoid or lessen skin purging, I’d recommend using a gentle BHA/AHA cleanser the morning before and after your retinol treatment. Adding this simple step cleared up my skin when I first started using retinol. It expedited the purging process.
