I was hesitant to spend this much on one product, but it has replaced two others in my routine. My skin is smoother, my pores look smaller, and I get compliments on my skin regularly now. In the end it has actually saved me money.
I love everything about C-Tetra Advanced. The packaging keeps it fresh, the pump gives the right amount, and the formula feels luxurious. Most importantly, my skin looks healthier than it has in a long time. My husband even noticed.
I usually do not write reviews, but this deserves one. My skin is softer, smoother, and brighter.
Gentle enough for my sensitive skin.
I started using this alongside my in office treatments and the combination has made a real difference. My skin heals faster after treatments and the results seem to last longer. I love that the team at Glow Theory helped me build a routine that works together.
