One colour for all that adjusts to skin tone? Not convinced

This product came up on my Facebook news feed with an amazing video illustrating several women applying this foundation; goes on white and adjusts to individual skin tones.

Product came from China, shipping was average. I purchased 2 bottles as it worked out to a better deal. Still ended up being $20 a bottle.

Product is a pump bottle, slight scent and white in colour. As you apply product you can see it blend into your skin although I found it more provided white dewy finish. Covers most redness although didn’t find it covered any blemishes or dark spots. Even when set with setting powder, with my skin tone I found it showed up white. More of a face cream than a foundation, very thin. Has SPF 15. Wouldn’t go out of my way to purchase again.
