    • I first tried this sunscreen when I received a sample and ever since I can not use anything else! The formula is light and soft. It goes on extremely smooth and absorbs within minutes! You do not feel it on the skin and yet it offers wonderful sun protection. It is amazing! I can not see myself using anything else again.

    • I have really oily skin so I don't like to put anything too heavy on my face and this is the perfect sunscreen. It sinks into my skin and doesn't feel oily or greasy at all!

    • I have sensitive skin, and my face gets red with most of the sunscreen, I started to use this one after I was introduced at a local store, and since then I have been using it for 4 years, high recommend!

    • I never used to wear sunscreen on my face. No matter what sunscreen I tried in the past, it would cause breakouts. The only reason I tried this sunscreen was because I was at Disney World. It was day after day of 95+ degrees of intense sun and high humidity. Had a free sample of Kate's Serum Sunscreen. I figured I give it a try. To my delight, it worked wonderfully! No sunburn, no oily feeling, and no breakouts!

    • I love this sunscreen. Works great under makeup!

    • It absorbs perfectly and I find it more effective than other sunscreens because it is a serum and penetrates your skin protecting it

    • I have used a lot of SPF's before, but this one is very weightless on the skin and a little goes a long way. I use it everyday after using my Kate moisturizer and it doesn't feel heavy on the skin as if I have too much moisture. I love it and recommend it to everyone looking for great products on their face....

    • I've tried a number of other sunscreen brands that have left small bumps on my face. My face didn't react with this product and it rubs in nicely without any white streaking. The only downside is that is appears shiny after applying, unlike dry-touch sunscreens. I tend to use this on days when I don't wear makeup but will be outside.

    • This sunscreen is so light and does not clog pores. I have combination skin which tends to be a lot more on the oily side in the summer- because of this I 've been searching for a sunscreen to offer protection without the grease... Here it is ladies and gentlemen- your answer!
      What I love is that I put it on in the morning and it protects me all day. Several times, I've spent the day outside my body was burned but not my neck and face (I was using a generic body SPF lotion)

      This is a MUST have for summer or if you are lucky enough to live somewhere where the sun shines all year long. Amazing!!!

    • I have only used this for a few days, but I really think I am going to like this. It does not go on oily and you don't even know you have it on.

    • I'm currently undergoing chemotherapy & have to be very careful about sun exposure. So many sunscreens can be greasy or clog my pores. This sunscreen is not greasy at all, nor does it clog my pores. Not only does it not cause problems with my skin, this product improves the look/feel of my skin!!! I can still enjoy my summer & go out in the sun without worrying about my skin or about my sun exposure! Thank you Kate!!!

    • I started wearing a high SPF on my face about two years ago. I'm 23 and realized how important it was to take good care of my skin. I have tried so many products and this one is the best. It doesn't leave a white cast and it doesn't smell like normal sunblock products. It also doesn't break me out!

    • I tried this sunscreen for the first time and have been using it on a daily basis. Before I never thought it was needed to apply a sunscreen because my makeup has SPF in it. I thought sunscreen would leave my face oily, but this one doesnt! Now its just another step in my skincare routine! love it!

    • I like this product, but it's nothing outstanding for me. It's convient to use, but for what you pay for it I don't know that I'd repurchase it.

    • I've never been a big fan of sunscreen but working outside this summer has forced me to apply sunscreen religiously. I was on the hunt for a product with high SPF that I could use on my face primarily, when I came across this product. I love that the formula is not greasy at all and I don't feel as though I have a thick film on my face. Great sunscreen with lots of protection.

    • i thought this would be a greasy oily substance to put on my face, but was not. I love having this product! The sun can be awful at times, and I know this is protecting me! This is a must have during the summer months. Plus it does not come off as white like most sunblocks that you have to rub in a lot!

    • Wonderful non-greasy SPF! Goes on very smoothly, and a little goes a long way. Lightweight enough to use over a moisturizer in the cooler months, even if your skin is a little oily. In warmer or more humid climates where you don't need a full moisturizer, it's great on its own. My skin is a little sensitive, and I did experience some redness in the first few days, but I haven't had any problems at all since then.

    • This sunscreen is great. I usually hate to apply sunscreen to my face and I hate the feeling it leaves. This is the only sunscreen that doesn't bother me. It goes on smooth and is not sticky. It's easy to apply and the bottle is nice. I would highly recommend this for every day wear.

    • I was in the market for a higher SPF sunscreen, however this did not deliver for the following reasons:
      1) Burned upon application
      2) Left face red and irritated
      3) Not suitable for sensitive skin
      I will let my husband try this, but I have since read after purchasing that other individuals have had the same reaction.

    • Love that I can put this on and than go about the rest of my routine. It's absorbs fast and doesn't feel heavy.

    • Broad spectrum and doesn't have that greasy sunscreen feel!

    • I have oily skin and this sunscreen is perfect for me. It does not leave me oily after wearing it and it does not leave a white cast like other sunscreens. Also, it's easy to apply is not a thick lotion. And no breakouts.

    • Love this sunscreen! It's great for using on your face as it's not at all greasy! Gives good protection. Also use this on my face and throat and have always had great results. Due to the price, I'd recommend only using in those areas and getting the cheap stuff for everywhere else though! You can go through an entire tube in a day or two for all-over application and reapplications!

    • I have purchased this product through QVC as one time purchase. Since I've started using it, I loved it so much that before I run out, I'll get it on Auto-Replenish directly from Kate's site. The sunscreen is amazing! It's very light and does not clog up my pores. I like the scent, too. Usually, I use it under my moisturizer and make-up, as it's the first thing I put on my face - after the cleaning. I would recomment this product to all ages and groups.

    • This is the only sunscreen that guarantees I don't get sunburned on my face and decollete. It is pricey but worth it!

    • I don't recommend this product if you break out easily. I used it and broke out all over.

    • My face always breaks out when I use spf moisturizers so I typically wear an spf foundation powder instead. I purchased Kate's serum sunscreen last summer prior to a trip to Arizona becuase I knew I would need something stronger, especially if I was in the sun all day.

      After 5 days of laying in the pool and applying this product once in the morning and once in the afternoon, I fell in love! This is a non-greasy formula that instantly soaks into your skin. My face never burnt and I did not break out once during the trip. I will never use anything else on my face when in direct sun again!

    • Finally a sunscreen that works for sensitive and acne prone skin! This is very lightweight but very effective. I had been using COOLA before but it doesn't go on as easily or have as high of SPF as this after trying multiple products.This product doesn't leave your skin looking white at all either. It's hydrating even for oily or combination skin. Hands down the best sunscreen!

    • If you purchase any Kate product it should be this one. I am a firm believer is sunscreen and have tried a number of different products, but Kate's sunscreen not only provides a high SPF but also it is not greasy AT ALL. I have sensitive skin that can be oily and have acne breakouts every now and then, but since using Kate products both of my issues have become much more manageable. As listed in the product title this sunscreen is a serum and absorbs very quickly where it doesn't even feel like a product has been applied. Strongly recommend.

    • I have tried literally hundreds of different sunscreens that were for sensitive skin, from super expensive specialty lines that made my skin burn and turn red to the heavy white potions that dermatologists sell in their office. Until now they either burned or felt heavy and super shiny, this stuff is great! About five minutes after i put it on there is no shine, no burn, no redness, and no oily mask. I hated sunscreens so much that i rarely used them on my face (naughty) and I have lupus so suncreen is super important. Now i use it everyday .

    • I have tried many sunscreens over the years and have a stong family history of melanoma. I tried this on a whim as I love and use many of Kate's other products and fell in love. It does not make me break out, leaves no white residue and works perfectly under makeup. I have had issues with other sunscreens making me feel "slick" and this did not do that at all. In fact, after a recent trip to a location with 90 degree weather, my face had no color, which is what I prefer, although I was in the sun the whole time. One pump is enough for face and neck so this lasts forever!

    • I live in Florida. I love the beach. That's the reason I moved here. Having said that, I also know that the sun I worship can be very damaging. Enter Kate Somerville. I have been using her SPF55 Serum religiously for 2 years now. Last time I had one of my bi-annual dermatologist appointments I had just returned from a 7 day cruise. She looked at my skin and said, "I'm glad to see you protected your skin so well". Kate's SPF55 is always in my beach bag. I put it on my face to neck including eyelids. No adverse reaction on my sensitive skin. Kate's products are really the best. I have tried many others thinking I could find something "cheaper" You get what you pay for. When I get to LA I can guarantee I will book an appointment at Kate's spa. That's on my bucket list - letting her team do their magic. Wish I was 30 so I could work under her and learn. What a brilliant woman. Read her book! Kate is the best!

    • I never knew how vital SPF's were to our daily lives until I had a class on how bad the sun damages our skin cells & collagen. I use to get sun blisters, sun breakouts and irritation all from the sun until I began using Kate's SPF....I never get sunspots, breakouts or blisters anymore. It truly covers the entire face w/ just one pump and completely protects your skin from all the sun's-badness! A must have for anyone and everyone!

    • OMG. Yes I said it, OMG. This is by far the best SPF over a 30 that exists. Not only is it NOT greasy (I hate being a goop face) but it also leaves my face picture perfect without giving it that white/gray/blue tint (you know what I'm talking about my darker skin peeps). Finally I can protect without looking like a ghost or having a oil slick mid day! Did I mention it stays put while swimming too? No more burning eyes when you're getting out of the water, move over Anita Ekberg (La Dolce Vita/Federico Fellini) and Bo Derek (10/Blake Edwards), here comes one more hot mama looking fab before AND afer a dip.
