What matches

Both protect with zinc oxide alone, 12% here against Tatcha's 10%, in an almost identical silicone base, and both add niacinamide, vitamin E, bisabolol and allantoin.

What the dupe does worse

Cetaphil has none of Tatcha's squalane, silk or hyaluronic acid and no tint, and it dries matte where Tatcha dries radiant, so the zinc is left to go sheer on its own.
