Zero stars smells like chicken bullion maybe I got a bad one
Scent: PDRN, Size: 1.01 Fl Oz (Pack of 1)
My husband even commented on the smell when he kissed me goodnight after I put this on, thinking I was crazy for thinking it smelled horrible. In the pictures online it shows it a clearish pink hue even in large puddles in their marketing. One pump of this comes out a gross cloudy salmon orange color, nothing like the picture. Maybe a bad batch?

Definitely worth a try
Scent: Red Effect Serum, Size: 1.01 Fl Oz (Pack of 1)
Absorbs well without leaving any sticky feel. I’ve noticed that my skin has better evenness and smoother texture. Starting to see less fine lines and a more hydrated and tightened complexion.

Worked on my pimples overnight. I don’t break out very much but this stuff really works overnight! It’s none drying and soothing. I recommend this product!
