I've been using this product for a couple of weeks now. I was hesistant at first, since my test patch on the back of my hand burned the first few second after I applied it. It didn't cause redness and quickly went away. I had this the first time I applied this to my face as well, but my skin got used to it quickly. I have no redness or irritation from this, my acne didn't get worse, and the sun protection is good. I'd definitely buy this product again!
