Yes, this is 100 percent a dupe/complete copy of the Tatcha primer. Most reviews will tell you that these two formulas are almost identical in application, finish, and result! The solid formula becomes creamy when worked into pores and creates a smooth base for foundation application. They also have formulas for hydration and mattifying, but the classic has the best reviews and is suited for almost everyone. If you love your foundation, but find it settles in a bit too much, this is an awesome budget buy.
