I have just used this for the first time today and will update at a later date. I bought this because I am going on vacation soon and will be outside a lot. But honestly I will probably start wearing sunscreen daily now that I have found this, assuming it doesn't break me out.
My skin is pretty normal, just a little oily in the T-zone, especially if it's hot out. I applied this VERY generously (1/4 tsp seemed skimpy since the formula is so thin) after moisturizing with a thin layer of mineral oil and it basically disappeared, leaving my skin feeling moisturized and comfortable. It seemed to somehow even out my skin tone and/or make me look radiant and well-rested. It's neither matte nor dewy, just sort of neutral. There was no physical sensation of a "layer" sitting on my face.
I'm a little fair-skinned and a makeup counter lady once suggested that I might have rosacea (I blush somewhat easily, and people often think I'm blushing out of embarrassment just because I'm smiling and my cheeks turn pink). Sometimes getting sunlight through the car window for 15 or 20 minutes will leave my cheeks and nose kind of pink and warm to the touch! I noticed today that I didn't experience the usual flushing/slight sunburn that I get otherwise.
My only complaint is that it really changed the application and end result of my Make Up For Ever Face & Body for the worse. Without this (or any primer) underneath it, the coverage is sheer and dewy. After applying this and giving it 15 minutes to sit, the MUFE goes on with more coverage and looks quite matte. Basically, I looked like I was wearing makeup which is what I try to avoid. I think it's just hard to spread a thin layer on a primed face because the formula tends to "stick" more. It's not worth taking off lippies though, because I think my skin looks great with nothing but this sunscreen. The price ( ~$40) is comparable to other HE sunscreens and is hardly a bargain, but feels worth it for a product that performs like this. continued >>

I recently bought this sunscreen after trying many sunscreens which made my skin greasy or shiny. My skin tends to be normal but all SS left me with a thick sheen on my face. Enter Anessa Perfect AA SPF 50, which is your typical runny Japanese SS but it soaks in quickly and doen't leave a film on the skin,My face just feels and looks normal.From the packaging it contains zinc oxide and titanium dioxide for protection.If you need alot of moisturizung this probably not the sunscreen for you.I have also used Peter Thomas Roth's Uber dry SS but I like the Anessa better but PTR was available in many places( Macy's, Ulta,) unlike the Anessa which I ordered from Beautykat.com., I have also tried Clarins UV Plus SPF 40 which I liked very well but a little greasy on me and I have used Neutrogena Ultra Sheer liquid SPF 55, ans it stung around my eyes but the Anessa has not caused any break outs or stinging on my face. I am loving this!

The crème de la crème, HG's of HG's, the end-all, be-all. This sunscreen is the best that I've found, so good I've stopped trying others because I'm so happy with this one. Sunscreen for me has always been a sacrifice of aesthetics for protection. You know, a little greasiness, a whole 'lotta white cast, all for the sake of staying wrinkle- and freckle-free into your 40's.

Let's talk about the Anessa. My skin actually looks BETTER with this on. Sometimes I actually use this at night (!) because it makes everything look poreless and perfect and I can't get the same effect with anything else. Like most Japanese sunscreens it comes in a bottle with a built-in shaker, and the liquid comes out runny like milk, also standard for Japanese sunscreens. Here's the kicker: it goes on like an oil, you can actually see the oily shine right after you apply it. After five minutes, the shine is COMPLETELY GONE and my skin looks genuinely matte, flawless and feels like I have nothing on. Nothing but smooth, velvety skin. It actually keeps my skin matte for 6+ hours and in photographs where I'm not wearing a stitch of makeup I still look like I actually have good skin, which I most certainly don't, hence the whole wearing-it-at-night business. If I don't use it, my skin gets visibly oily and shiny around the T-zone area in 3-4 hours.

The second thing that really impressed me about this sunscreen is that there is absolutely NO white cast, and I mean none. If I apply more than the full 1/4 tsp., still no white cast. I've tried the Senka's SPF 50 (blue bottle) and 27 (white bottle), the entire Bioré UV series, Sunkiller, Anessa's other sunscreens including the Perfect UV SPF 50+ EX (the older, waterproof formulation), Sofina, Kanebo's Allie Protector SPF 50 Perfect Alpha, Shiseido's Japanese line, the various Metholatum ones and many, many others. With the exception of Bioré's UV Aqua Rich Watery Essence/Base and the Senka SPF 27 all of them have left a white cast on me, some worse than others, and the majority of them have looked and/or felt greasy despite the descriptions on the labels.

The last two things I wanted to mention is that it IS as UVA-protective as the PAA+++ rating suggests and prevents me from getting any color after spending all day outdoors. My skin tans very easily and on days I forget to wear this the incidental sunlight exposure darkens my skin significantly. Now I'm not too neurotic about receiving some light damage once every few months or so, and I do like the way a little color looks, but I know for certain that the Anessa is keeping me from tanning because on the very few days I don't wear it, I see a huge difference. I can't say this about the Bioré Watery Essence, which seems to melt off in a couple hours and doesn't stop me from getting color at all despite the PA+++ rating. The Anessa also mysteriously stays put throughout the day but comes off easily with a regular non-oil cleanser. It's truly the "perfect" sunscreen for me and since they've started putting expiration dates on the box label I've bought two bottles as back-ups.

Background Information:
In the spring of 2011, Shiseido's Japanese counter released a newly reformulated line of sunscreen. Shiseido's Anessa is the most prominent brand for sunscreen in Asia, where I grew up (Taiwan). It's so well known, that if you were to walk on the street, grab any random person and ask them which brand makes great sunscreen, many of them would answer, "Anessa." The Perfect UV Sunscreen has been Anessa's star product for many years. This gold bottled Perfect UV Sunscreen AA (instead of the old EX) is the newest (2011) reformulation. The new line of sunscreen also boasts to be able to be removed easily with soap and water, something I am not sure drug store sunscreens in Asia have been able to do yet (and need to be removed with a cleansing oil like the previous generation of Perfect UV).
It has an SPF of 50+, which would block out at least 98% of the UVB rays. Since many Asian countries have a cap on the SPF at 50, we do not know the exact SPF value other than that it is definitely at least 50. It also has PA of +++, which means it has a PPD of 8+, which in turn means that it should allow a person 8+ times as much UVA exposure as would be without protection. The Japanese system for UVA rating only goes up to PA +++, so it's impossible for consumers to tell what the actually PPD is, other than that it's above 8.

My thoughts:
So far (2 weeks) I really like this sunscreen. No matter how much I apply, it leaves absolutely no white cast. The texture is so thin, that I feel it to be half as thick as the normal Shiseido counter sun protection lotions (Ultimate Protection SPF 60, Ultra Smooth SPF 38). Normally, I would have trouble applying the required amount onto my face at all with the two mentioned above, but I can without too much trouble with the Perfect UV. This makes me absolutely delighted!
At first, when I applied the correct amount of 1/4tsp (1.23mL) on my unmoisturized face, I felt that the sunscreen felt a bit greasy. Not as in over moisturized sticky, thick, and oily greasy, but a weird thinly layered kind of greasy. However, after 15 minuets it dried to a natural looking, semi-matte (maybe satin?) finish. It is definitely no where near as matte as the Biore UV Perfect in the white bottle at all, and it also does not control oil as well. But then again, Biore UV Perfect tends to be way too matte and drying for many people. I only apply Biore to my T-zone, as it would just make the rest of my face peel when I tried to apply it all over. I have no such problem with the Anessa Perfect UV, even though it does not control oil half as well (Biore is HG for that purpose). However, I dare say it is much better than either Ultra Smooth and Ultimate Protection.
The Anessa Perfect UV also has great staying power. Shisedo says that it is water resistant (ie. can stay on in water for up to 80mins). It is also sweat proof (unlike Biore, which leaves a white mark on my upper lip, where I sweat very much in hot an humid Taiwanese summer) and stays on decently through the crazy oil production of my T-zone.
For removal, I'd say it's possible to wash of with soap and water when the soap is massaged on to the skin for a while with care. However, I tend to wear eyeliner on my eyes all the time anyway, so I generally use a makeup remover. (We should also note that this is supposed to have the best staying power of the entire line put out by Shiseido, so one must take care to remove every trace.)
.....
Although I'm still trying it out, from initial good experience at the Shiseido counter, I have already purchased 2 bottles of it (for the GWP of a mini Perfect UV Sunscreen and a mini Mild Face Sunscreen of 12mL each). I will probably still love my Biore more for hot and humid summers in Taiwan, but when I go back to New York State after the summer, I will probably like to use it more, as I can apply it to my whole face rather than one SS for my T-zone and another for my cheeks.
