I tried Tatcha last TSV. I feel the products are really nice. I might not go buy them full price and thanks to Q for such fantastic deals, especially the TSVs, I might not have to binge on retail prices. I have sensitive skin and am a minimalist with makeup and skin care (Early 40s) but I do hear people saying my skin looks very healthy and dewy, especially in the past year of Tatcha Use. I was stalking Q for this year's TSV. I love the eye cream. It addressed my tea bag stains and specially during my spring allergies, which I experience more in my eyes, It was Godsent.
I had used the essence for a year now, my skin feels plush and glowy. I didn't order the TSV yet as my last year's tsv is on AD and I have gathered a stash and I already have the scrub from another BOGO qvc deal. The eye creme and moisturizers are a repeat from last TSV so I am thinking if I need this. I might cave in during presentation though 
I especially like the women behind the brand, I follow them on Insta and they are such positive, caring and supporting women to all their patrons and followers.
I know everything doesn't work for everyone, but the TSV is a great price to try out. And the products are so rich and potent that they last a long time. Little is more, so in the big picure, the value is incredible.
Hope this input helps
