I have an off and on relationship with this sunscreen - it's a heck of a lot better than most Western sunscreens on the market, but it's not perfect for me. If I'm living in a country where it's easy to get, I'll buy a tube, but if I can only get it online, I won't.
Pros: Incredibly lightweight, great protection, and easy to carry in your purse or handbag. I love the citrusy smell. There is no white cast and it doesn't leave any shine on the face. Also, it's fairly inexpensive for the level of quality.
Cons: It's quite drying. I have oily skin but this tends to dry out my skin. I don't mind this if I'm not wearing any makeup on top, but if I'm wearing makeup on top of this this will make my skin look haggard unless I'm living in a tropical country where it's very humid. Because it's drying, my skin produces more oil to compensate which results in whiteheads. I usually combat this by double cleansing and exfoliating with an AHA toner at night, but sometimes it's too much of a hassle for me.
Also on another note: this sunscreen is optimal for normal everyday use (going to the office, or day to day errands). But if you're on holiday or going to the beach, you should be using something with a bit more protection and honestly it should be a physical sunblock as opposed to a chemical sunscreen. I can tell you from personal use that I've gotten more tan with this sunscreen than say, EltaMD's UV Clear Facial Sunscreen SPF 46, which is a mineral based sunscreen.
Overall: My score is a 3.5. It's a cult favorite for a reason, but I like something with a bit more moisture even if my skin is quite oily. My HG is the Nivea Sun Protect Super Water Gel SPF 50/PA+++, which is more slippy and pleasant to use.
