This is light and none greasy good over makeup 

Feels nice on the skin and so far seems worth the money

I always come back to this. I hate sunscreen on my face, but this is light and effective for protecting my skin. Spray in a ventilated area though.

Ultrasun do great SPFs and it's really handy to have a truly invisible spray for top ups and hair. This is the only one for scalp / hair I've come across that doesn't make your hair greasy or need to be applied to wet hair. The only negative for me is it's so invisible I worry that it's not applying properly or just gas coming out! Good size for handbag / travel. I use the larger size at home. 

Good product, great for applying on the go throughout the day due to its small size - but expensive for this also. Works well over make-up but similar products are available at a better price.
