1% Retinol Serum.

"The biggest issue for me was with their original 1% Retinol Serum. It said 1% retinol all over the packaging, so I thought that's a good dose. I started my retinoid journey with it, but then it came out that it wasn't a 1% retinol, it was a 1% retinol-star complex, which was actually a compound of different components, and when you broke it down it was the equivalent of about 0.2% retinol. That's doing nothing. This emerged online, people started talking about it, and then it was confirmed with the new EU retinol restrictions, where The INKEY List can still sell their product into the EU because the concentration of retinol is below 0.3%. It really just became very apparent that the marketing was very misleading from the start, and I trusted my skin with that product and wondered why I maybe didn't get the same results I was hoping for. It's because we weren't really getting the percentage we thought we were. Shady, shady, shady."

"This is the retinol Inkey List serum which is a good starter serum and I would always start with retinol rather than anything a little bit stronger. You can use this on the face quite nicely. I would not use this in the daytime because it can sensitize the skin, and if you sensitize the skin and then expose it to UV you could cause some damage to your skin. So if you're going to use retinol you want to use that at night."

"This is another great one, the 1% Retinol Serum from The Inkey List. I love The Inkey List and The Ordinary because these are both like under 10, 15 bucks, so they're affordable. If you're going to spend your money on something, spend your money on a potent active ingredient and get it at an inexpensive price and try it long enough, like a month or two, to see if it works for you."
