Some of the reviews say this is only a 1 ounce bottle. The picture shows a 1.75 ounce bottle. What size is the bottle?

My physical bottle says 1.75 oz.

How well does this work with fair skin? Most tinted sunscreens are too dark for me.

I think it might work for you. It is a lighter tint than most tinted sunscreens that I have used and not at all orange-y. I have light skin, and it is a bit light for me. I often mix with other, darker sunscreens if I am wearing it alone/as my foundation.

Do I need to use makeup remover for this one?

You apply this cream before your makeup. It acts like a moisturizer and sun blocker. In the evening you will need a makeup remover. This cream should not be used for that purpose.

Is this a mineral sunscreen, like Tizo 2 & 3?

It is a morning moisturizer with Tizo’s mineral sunscreen. Tizo does have a different product that is just a sunblock. I use this under my foundation everyday and it works very well as a primer and sunblock.
