I’ve use the original p50 1970 before and loved it but since they don’t make it anymore I’m back for the P50. This is a staple for me. Best toner I have ever used.

Amazing product
An amazing product extremely fast shipping. This is a good exfoliating product that shows results quickly. Gives a retinol glow without the retinol. Love it!
