This was recommended to me earlier in 2022 and I am currently at my 2nd bottle now. My skin is receptive to it so far and it has been a positive experience using it. However, as an avid user of TSP products since 2017, I would say that the effects of their serums are quite slow in general. You need go through at least 2 bottles to see visible improvement in your skin. I hope TSP would improve their formulation over time. Your serums are really not cheap and I expect better results given the amount that I am paying.
