Overall, I really like this. Doesn't feel as strong as BR P50, which I like, but definitely doesn't replace BR for me. The texture is very watery, hard to dispense in your hands as it runs all over the place. Definitely best to apply in a cotton round or directly on skin (I dispense the product this way so I don't waste any product in the cotton round but it is a little hard to do). You feel a very light tingle in some areas and automatically feel an improved texture to your skin. Per Ben Fuchs recommendation, I apply this before using my Transdermal C Serum and SPF.
I love truth treatment products and this is no different. It is great toner. I use it a few times a week, and my skin loves it.
I've tried a lot of acids and acid toners, but this one is the only one my skin tolerates. Strong but great!
