Makes me look good!

I know this says use twice daily but I've noticed it working well with even just using it at night. I don't understand a lot about skincare but this makes me look good so I use it!

Great for maintenance

This is my favorite serum of the five million I own. I feel like it's such a go to that's great to improve overall skin quality. I'm at a point in my life where my skin is 'stable' enough that I'm not reaching for many cures to specific concerns, I'm more interested in maintaining my skin at the place it is. This serum (among some other tried and true BT products - hey sonic!) is one I love to use at night just to keep everything looking it's best.
