A little bit, but if you wear powder or bronzer over it you can cover it up.

It is a white light weight cream, but does not leave a white film on your face like many other sun blocks do.

Question
Is this a moisturizer?
As not all sunblocks are, is this a moisturizer? Or is it meant to go over a moisturizer? Can it just be worn over the serum? I'm 59 and havean oily t-zone.

I use it over a moisturizer. But it really depends on your skin. I have an oily t-zone as well and don't find that it makes me more or less oily. You might try with and without a moisturizer and see.

Yes, it's a moisturizer with SPF 50, which is way better daily protection than the SPF 15 found in most moisturizers.

I haven't tried the Clarins but I love this it goes on smooth and I like the SPF factor

The difference is that Clarins sunblock is not broad spectrum: the only active sunblocking ingredient there is titanium dioixide which does not protect against all uva rays, that as we know, are responsible for aging.

Question
How do you remove this sunscreen?
The Algenist Ultra Lightweight UV Defense Fluid stays on SO well that it won't come off at the end of the day without some kind of very very heavy duty exfoliating product. Not even a Clarisonic will get rid of it! Is there something else that will dissolve and remove this sunscreen at the end of the day? It's my favorite!

I've been using this product for a year. I've noticed that it's difficult to wash off my hands when I wash them immediately after application. However, by the end of the day, I haven't had any issues washing it off my face. Have you tried a mineral oil based makeup remover?

Question
Can this be applied to eye contour area?
I used the Clarin SPF40 and it can be applied to the eye contour area. I tried this product and love that it goes on clear and leaves a light matt finish but was wondering if this can also be applied to the eye contour area?

The active ingredients are Octinoxate, 7.5% Titanium Dioxide, 2.0% Zinc Oxide, 17.1%, in my experience it should has at least PA++ strength.

PA is our Asian thing... I think it's some Japanese rating, PA is just some '+', the more '+' it has the more sun-protective it is. I don't think PA rating has a big difference with the SPFs, only that SPF is easier to calculate (like SPF rating * 10 minutes or so)
