MeloraHeliocare Gel Spf90 50ml

So the description says same formula and ingredients as before meaning it has a 90+ protection? Is this suitable for oily/combination skin?

Is this good for brand new scars?

this is gel protection, has any color, its special por oily skin?

Why is it "previously spf90"? they are still selling spf90 version. i'm confused. is 90 is thicker and 50 is thinner and easier to apply?
