This has been great! Most of my fine lines are gone and the deep lines much less prominent. This was my first usage, so I’m going up from the 3 to 6 next to see what that does to the deep lines.
Amazing product - was a bit worried it might cause irritation as I’ve found retinol products difficult before. However this was great and made such an impact from day 1!
