The nice thing aout Kara Vita's Suncare 15 or 30 is that they are 8 hour time release products so they will last a full 8 hours without reapplying. They are waterproof, sweatproof and rubproof so they are excellent for kids as well as adults.
They moisturize too. A little goes a long way so the 8 oz bottle, although it seems expensive isn't, because lasts a long time.
I like this product very much.

Oh my gawd, I love this stuff! Why hasn’t there been any reviews written on it?! I’ve been using my samples of this SPF facial moisturizer (I think I have SPF 15) and as someone who has tried literally dozens – this one definitely stands out! It’s quite oozy and somewhat thick, so you would think it would be shine, nonabsorbent city for someone with crazy greasy T-zones such as myself – however it’s completely not! It absorbed (evaporated maybe?) rather quickly and I did not end up with the “freshly greased” look I usually have after slathering on facial moisturizers. I looked perfectly glowy, like I had just washed my face and it had a been an hour or so – when my natural oils come back onto the scene. Past that hour, I become Texas’s undiscovered wealth of oil fields – it’s true. I am really considering purchasing this stuff after I’ve depleted all my SPF facial moisturizers and I’ve tried out more samples. Seriously, it’s THAT good!
