Actually the amount of sunscreen to be used has been re-calculated: it is 1-1,25 ml for just the face, or 1,5 – 1,8 ml for the face and neck.
In the old calculations the fact that we have hair on our heads had been ignored.

A good place to check how much UVA and UVB protection a sunscreen gives and whether the ingredients are safe or harmful is http://www.cosmeticdatabase.com

Also, chemical sunscreen penetrate the skin and enter the blood stream (and may mimic hormones), while physical sunscreens do not.
Certain ingredients in chemical sunscreens react with ingredients in make-up.
If sunscreen contains Parsol 1789 (Avobenzone, Buthyl Methoxydibenzoylmethane,
avoid:
octyl methoxycinnamate (popular UVB filter in foundations),
talcum
mica
zinc oxide
titanium dioxide
some CI colorants

So, I’d recommend physical sunscreen, especially on kids. If you want to go for chemical, research first whether it is photostable. For physical sunscreen, avoid those with nano particles.

One last thing, the technique of application is extremely important. Pat the sunscreen in to for a layer, because rubbing it in just smears it away.

Hope this is useful !
