I started using the P-Tiox serum for almost one week, twice a day and all I can say how lovely it is.I can see visible results for a very short period of time which is truly amazing. My skin looks smother and radiant. It seems like the peptides are working at its best possible way. My wrinkles are slightly reduced and my skin texture as well. It has no smell so after applying a few drops on my face it gets a little bit sticky but only for a moment. After a few minutes the stickiness disappears and my skin looks glowy and smooth on touch. It is powerful but also gentle to my skin at the same time which I really like. I can see no irritations on my skin so I guess It is suitable for all skin types.It is truly an amazing little germ.Highly recommend!
