I want to know about a sunscreen that is gentle on the skin.

I have naturally sensitive, acne-prone skin, so I can't just apply anything. I specifically look for cosmetics with gentle ingredients like Cica. However, with the strong UV rays these days, I can't go without sunscreen; if I don't, my freckles flare up, so I've been applying it frequently. The problem is, I'm not sure which ingredient is wrong, but after a short while, my skin feels rough—or should I say, dry?—so I can't leave it on for long. It's inconvenient because I have to wash it off quickly and reapply it. There are also many different types of sunscreen.

I've tried applying a lot of different products and had many failures. I didn't think my skin was that sensitive, and other makeup is fine, though.

It's only sunscreen that does this. Please recommend one you've tried that is gentle or provides good protection but feels like you haven't applied anything at all.
