I'm not a fan of chemical sunscreens, but this one exceeded my expectations. It's not irritating at all, does not sting. It's completely scent-free and you can actually apply a lot (as dermatologists recommend) without having either a white cast, occlusive or greasy feel. It spreads like silicone based cosmetics (although as I understand this one has none), but does not evaporate like silicones. It stays on your skin, giving it a nice glow (but not a greasy glow), my skin feels hydrated for a long time. What I also like about this product and many other Korean products is that it works on nourishing the skin without oils. I don't have blackheads or acne, but I do have sebaceous fillaments. When using this SPF and other Korean products, they do not appear as fast. In fact, if I had to squeeze those out (yeah I know that's not the best approach) every 3 days, I can do that now in 7 or 10 days. Again a very good product for a great price. Goes well under foundation too!
