Restor8 Replenishing Serum
2 points per dollar


This silky serum utilizes the proprietary Restor8 Complex to address eight signs of aging: wrinkles and sagging skin, dehydration and lack of volume, dullness and uneven pigmentation, roughness and enlarged pores. A sophisticated concentration of Vitamins, Nutrients, Peptides, and Antioxidants helps to smooth and firm, moisturize and plump, even out skin tone, and refine texture.

Restor8 is a proprietary complex of rare ingredients that produces a wide array of anti-aging benefits, including:

  • dramatically diminishing the appearance of expression lines and firming sagging skin;
  • enhancing the skin’s lipid moisture barrier and locking in essential hydration to plump up skin;
  • improving the skin's reflective ability in order to mask skin imperfections, while reducing redness and dark spots;
  • smoothing skin and evening out texture and tone.
  • Oil-free formula is ideal for all skin types. 
  • Available exclusively at Kate Somerville, Neiman Marcus and Bergdorf Goodman.

    • I love to get the free samples with my orders- but everything I try I end up wanting to buy! This serum has done amazing things for my skin. Even though I am acne prone, it doesn't cause my skin to breakout!

    • I love the smell and texture of it and it works perfectly with my skin. My skin feels so silky every time I use this and look better. I totally agree with the other review you really get a baby skin.

    • I received a sample of this serum when I placed my last order. If it was less money, I would order it in a heartbeat. I love the smell and texture of it and it works perfectly with my skin. My skin feels so silky every time I use this. I will consider ordering the full size of this product in the future.

    • I try everything and am under the care of a very well known Beverly Hills dermatologists. I do use some of his prescription products, but just haven't been able to get rid of this peri- menopausal skin dryness. I got Restor8 sample with another purchase and looked like I had baby skin in the morning. Without a doubt, it is my next purchase. Yes, it is pricy, but even better than some big brand names that are even more. Thanks Kate for another great product!

    • I knew I needed to include a serum in my daily routine, but couldn't decide which Kate Somerville serum to use. The salesperson at my local Nordstrom was very helpful providing a sample of the Cytocell and Quench, but I kept returning to the website for Restor8 so I ordered it. I love this serum. It has a creamy texture that goes on smoothly, penetrates quickly, and does not leave a sticky feeling to my face. My face feels smooth and hydrated with just one pump for my entire face and neck. I highly recommend this serum to anyone who wants their face to look the best it can.

    • I have tried many types of serums including some others by Kate Sommerville. By far, this is my favorite. The serum is not runny, but a smooth lotion that soaks into your skin immediately. It does not feel sticky and provides a great base for your moisturizer and night creams. And it doesn't take much to cover your entire face and neck - 2 drops which makes the cost very affordable. Another great Kate Sommerville product.

    • Pros: effective, hydrating
      Cons: funny smell, very oily texture

      I usually like milky serums, so i was surprised at the oily consistency. I was very hesitant about using it due to the fact, but I'm glad I did because it works beautifully on sensitive skin :)

    • Winters in California are rough for my skin, it's usually dry and congested, a horrific combination. I used this in addition to my Nourish moisturizer which just wasn't cutting it for me and was beyond impressed with the results. I'm usually hesitant to try serums on my acne prone skin but I had a larger sample and just overnight it worked miracles on my dull, dry, winter skin. While using this product my skin was noticeably softer and more radiant. The serum is light and it didn't exacerbate my acne-prone congested skin in any way. Since running out of the sample I have also noticed my skin was in far better shape while using it. This is a skincare must have!

    • This product really improved the tone and texture of my skin. It reduced redness and did not irritate the skin. It was a great product to use before moisturizer. A little goes a long way when using this product.

    • Well, Kate continues to amaze me! As a few other reviewers have mentioned, I received this as a sample and am stunned to see the results. I tend to apply this only in the morning and enjoy an entire day of calm skin. During times of stress my skin tends toward rosacea; recently, my skin has suffered terribly due to a higher than normal stress level. After applying this for 1-2 weeks, my skin has calmed incredibly. Additionally, my pores are smaller and my overall facial appearance is firmer.

    • This serum is really amazing. Restor8 has really been a lifesaver for my face during winter. I use it twice a day during the winter months, and it provides enough of hydration for me for the entire day. It is also packed with vitamins, so my face glows instead of the usual winter dullness. I now do not know what I would do without it.

    • I've had several samples of this product and can hardly believe the difference in my face. It has evened my skin tone, reduced my pore size, and given me a beautiful glow. That's hard to get at 65. I will definitely be ordering the full size. Thanks Kate!

    • I am obsessed with this serum, I received a sample of it with my last KS purchase and can't get enough of it! After a handful of uses, I am amazed at how soft my skin has been since using it, my skin also appears more even and the texture is smoother. It is currently in my wishlist and am saving up so I can purchase the full size! I can't say enough how excited I am to have discovered this little gem!

    • I have tried all of the Kate serums and there are very few that I don't like. However, this one is my absolute favorite and I always make sure I have it on hand. It's got a great texture, tolerable smell and it soaks into the skin perfectly. I use the moisturizer cream on top of it after it's completely dried.

    • I've received several samples of this serum, and I'm hooked! I will be definitely be purchasing it sometime soon. It's a more expensive serum, but definitely worth the price. A little bit goes a long way and it will last for a while! Leaves your skin feeling great all day long!

    • After trying the serum only one time, after using exfolikate, the results were astonishing. I love this product, along with Exfolikate, and deep tissue repair. My skin glows, and feels so soft. Makeup goes on beautifully., and even bare skin looks great.

    • I've been using Kate skin care line for over 2 years, first started with price-friendly serums like Quench ( which I still love ), but being tempted by a sample of this, I fininally got a full size and loving it. I especilly love its instant effects on red swelling pimples on my chin, you can see them diminishing day by day and prevent a lot of painful fights with big red pimples. I hope after a few more months useage of this serem, my face would look brighter as well.

    • I love everything about Restor8. It is easy to apply and sinks right into my skin. Feels like velvet on my skin and gives me an incredible glow. I use it in the AM and PM. I am seeing a slight reduction in my fine lines which is another plus.

    • Make it this one! This is a pricey item however it is the one my skin cannot live without. I put this on at night and I wake up to hydrated plump skin that is even and fresh. When I forget this in my nightly regime I can see a huge difference and not a good one!

    • This is an amazing serum. I use the Quench serum and decided to try this to switch it up. I am so glad that I did. My skin feels so smooth- amazing! I love to use this at night & quench in the morning!!

    • I first tried this serum in a sample, and I knew I had to have it. My skin feels so smooth and looks plumped up, replenished. I use it during the day with an spf moisturizer over it, and at night I follow-up with Kate's age arrest cream. The overnight combo is unbeatable! You'll wake up in the morning seeing a more youthful face!

    • Restor 8 is the best serum I have found. It makes my skin feel like velvet and gives a lovely after glow. In the morning my skin is baby soft and my wrinkles are softened. Thanks Kate for another great product.

    • I've been using this for 2 weeks and I am very happy with it. It is incredibly smooth and silky, but not greasy feeing. It gives an instant dewy Glow. A perfect compliment to all my other favorite Kate products! It has made my skin baby soft, plumped up, refreshed and youthful, even toned and is full of vitamins and replenishing ingredients that make my skin feel 10 years younger!

    • I have been trying different serums for a long time, and never found any that worked for my skin until I found KateCeuticals Restore8. I love it, my skin feels so smooth and the texture has improved tremendously! Great product!

    • This is a wonderfully, smooth serum that leaves your skin looking so much better after application. Skin also looks so beautiful and fresh in the morning. I use this mainly at night, but sometimes during the morning. I notice a deifnite difference in appearance, texture, glow if not used in the morning. Even with temperatures rising in Texas, my skin looks great, not oily or greasy at end of the day. I balked at the price, but it is well worth it.

    • I have combination skin in the extreme. Really oily t zone and dry cheeks. I tried everything to get my face from either breaking out or being flaky dry. I discovered this product by accident and haven't stopped using for the past 7 months my skin has improved so much. I love the smell, texture and how it moisturizers but isn't greasy or heavy and doesn't make my skin break out! And plus it had all that anti aging stuff in it to boot. A+ product!!! Thank you!

    • I immediately fell in love with KateCeuticals the moment I tried them. From the cleanser, to the eye cream, and everything in between, these are products that I will always have on hand. I absolutely love the effects on my skin ... firming, moisture, no more dark circles, and on and on ... LOVE these Kate!!

    • I am 47 years old and can honestly say I have tried everything for my skin. I was one of those people who didn't use sunscreen back in the day and my skin has certainly suffered from it. I decided to give Kate Somerville products a try and will now be using them exclusively from here on out. The Restor8 serum is truly magic in a bottle. It, along with the other Kate Somerville products in my skin care routine, has made my skin so alive, soft, supple and beautiful! I am hooked for life!!

    • After using KS serums and moisturizers for a few years, I now use this serum at night. It is thicker than other KS serums and slightly tacky in texture. Apply it before KS Multi Active Repair Cream. In the morning, skin looks amazing.

    • I decided to treat myself to this serum. A little goes a long way. I have some redness to my skin and dryness. This serum is wonderful. It does not clog pores or irritate my skin in any way. I definitely find it helps with my redness.

    • I'm almost 50 and discovered Kate Somerville products when I was in my mid 40's. I was struggling with eczema and acne for the first time in my life as well as aging skin. Kate Somerville products were the only ones I could tolerate well. I started with Deep Tissue Repair, which was excellent, and eventually migrated to the Multi-Active Repair Cream and the HydraKate Line Release Face Serum. I was in Nieman Marcus recently and took a sample of the Restor8 Replenishing Serum. I love it - it's so rich and light, smells divine, and absorbs quickly the way all Kate Somerville products do. I already see results after a week. I'm using it in the morning under sunscreen and at night with the Multi-Active Repair Cream. Hats off to Kate Somerville for another great innovative product.
