This is a really great sunscreen. Leaves your skin moisturized and does not leave a white residue. I always wear sunscreen and this is a winner to me. Smells nice too.

Is this even real?!!!
Style: Face, Size: 2 Fl Oz (Pack of 1)
Ok, I am a sunscreen fanatic and have tried most products on the market and I am SO impressed with this product!!! It is by far the best daily facial sunscreen I've used so far!!! I really can hardly believe it is a (non-nano) zinc base as it leave absolutely NO whitish finish.
First of all, it's hard to find a sunscreen with only physical UV blockers (zinc or titanium) without any added chemical blockers. There are a few (including the Korean skincare products) but they ALL leave a white film. This is the FIRST all zinc sunscreen that looks completely natural after application. I still have NO idea how they did this without using nano-zinc!!!
Second, the texture and finish are so light and non-greasy that I cannot tell that I put anything on my face. It's fantastic!!! It absorbs right in!! Granted, I do not have oily skin so I cannot speak for someone who does. It isn't drying but also not super moisturizing so if you have dry skin, you might want to use a heavier cream under this product.
Third, the smell is light and pleasant. i do not find it overwhelming or distracting. I rather like it.
The downsides are (1) it is not inexpensive at about $20/2 oz and (2) it is not sweat resistant (though it suppose that would come at a cost of a more greasy texture).
I love love love this sunscreen!!! I only started using it recently so I'll see if it really works well to protect my face from UV exposure... I'll update this later regarding the effectiveness as a sunscreen.
Thanks for a fantastic product!!!
