Perfect for daywear as a base for my makeup.

I’ve been using this for about 8 years. I stopped for about a year during some difficult health problems. When I got my new bottle in, my skin was back to the way it was when I started the serum 8 years before.

Quick ship, great customer service.

It works well, gentle.

This is truly working. Tightening, brightening, and looking a little younger!
