,Face sunscreens are dissimilar to all purpose ones: most incorporate skin care + the usual mix of UV absorbers and scatterers.
More and more they are presented as ‘Anti-aging’ as UV rays are responsible for most of the ageing signs on our skin: sunspots, lines, wrinkles.
Which sunscreen would be best for us depends on our type of skin (sensitive, dry, etc.,) and our age: young skins break out if cream is too rich, and older ones would feel dry without a rich moisturiser. There are also appropriate ones for sensitive skins.
The Ultra Violette sunscreen has other ingredients besides UV blockers: moisture attracting Glycerin, shiny Mica, smoothing Dimethicone, and many others.
Also, as it can be applied by a dropper, it would last longer than a tube which can be squeezed too much.
But it looks like it is more of a cosmetic plus sunscreen, and that would explain the hefty price tag.
