Super easy. Goes on evenly.

Super easy. Goes on evenly. This is put on after toner to prep the skin to receive all the benefits of the moisturizer. Super chic look for packaging. You can remove the original sticker. Quality is terrific. I love it.

Would Buy this Again!

I use this every morning and night in my skin care routine. I love how hydrating it is, especially in this really dry winter season. I do not get any breakouts or feel like it negatively affects my skin. It’s been a great addition to my routine.
