Rated 4 out of 5 by from Nice serum! I do have to say this is a very nice serum! It honestly worked great the first day I tried it! I have dry skin and it made my skin so soft and took away some of the dryness around my nose. The downfall is the smell. I personally do not like the smell. At first I honestly did not know if I could deal with the smell but after the first few uses its not terrible and you get used to it but not the greatest smelling product I have used. Price point is a bit steep but this is a reputable and good company so if the product works great and does not irritate my skin I dont mind spending a little more money. Between price and smell Im knocking off one star.

Rated 3 out of 5 by from 3.5 stars I was very excited to receive this product for free from Influenster to test because the price point is a little higher than I would usually spend on a product Ive never tried. I love the consistency, its very easy to spread on your skin and you only need one pump. I noticed the smell next and its kind of gross. Its very leafy/natural? It smells like grass or something, Im not sure. I havent noticed a huge difference in my skin and for such an expensive product, I expected more. My skin is a little smoother but I can only tell because my foundation goes on a little better. I wouldnt buy this for myself but I will finish the bottle.

Rated 5 out of 5 by from Lovely texture, glowy skin! I love this product! Im already a fan of Kiehls and am always excited to try their new products. This formula is sooooo silky smooth. Its texture is very much a liquid, yet when worked into the skin it almost feels like a light cream. I have been using it in my routine right after I get out of the shower, when my face is slightly damp. Lately, Ive been stopping there, and my skin literally glows! I feel that my skin tone has been more even and vibrant while using this and it just feels so luxurious. Id compare it to Glossiers Futuredew. Overall, I LOVE this product and I may just have to splurge on another bottle when this one runs out!

Rated 1 out of 5 by from It had no visible effect on my skin and seems like pointless product. I am a really loyal Kiehls user, almost 3 decades now, and so frequently I will try something new even though I have my favourite products, I gave this serum about 2-3 weeks. The consistency is a bit watery and the smell is overly floral. If the serum worked I could get past both, however, it did absolutely nothing for me so I returned it. In fairness, I have been using 3-4 Kiehls products daily for decades. My skin looks really great for a 57-year-old so maybe I have maxed out on returns from a skin product. If you are looking for a serum for ageing skin, you cannot go wrong with Powerful Strength Vitamin C Serum. It is one of the best things Kiehls makes in my opinion.

Rated 5 out of 5 by from so fresh, so bright!! I love this serum. This is the first time Ive ever used a serum. Ive been using it in the morning and at night for a two months now. It has no scent and its not sticky. One pump is enough for your whole skin and face. I loved the cute design and the pump itself had a cap so it was easy to travel with it. Your face does not feel oily just hydrated and refreshed. Ill definitely buy it once my complimentary bottle runs out. Thank you Influenster for letting me test this product. Im attaching before and after pictures (please excuse my bushy brows). You can see my skin is more hydrated, brighter, and my dark spots even look better!!

Rated 4 out of 5 by from Kiehls super serum So excited Influenster sent this to me to try. I have added this product to my routine 2 times a day and havent stopped since I received it. I love how you can apply it under moisturizers. It spreads and goes on so nicely and smooth! My skin soaks it up but at the same time doesnt get dry. I cant say I see anything change drastically but i feel like it is strengthening my skin some. Im going to continue to use the whole thing! The smell isnt the best but its not bad enough to get me to stop using it . Im really curious to see if by the time I go through the bottle Ill be able to see a greater difference.

Rated 5 out of 5 by from great product Things I liked - a little goes a long way, gentle on my skin (I would caution against using it if your skin is overly dried out for some reason or you have gotten a little too much sun). It is fairly easy to control the amount of product that comes out of the pump top. Packaged nicely and easy to read instructions. I liked the scent as well, it was pleasantly surprised by that. I personally tend to forget to apply it twice, so usually I either remembered when I woke up or right before bed time. I felt like it smoothed my skin and helped it stay moisturized. I hadnt tried this product before and do like it. I plan to continue using it.

Rated 5 out of 5 by from Perfect for my sensitive skin I bought this a few weeks ago on the Kiehl's website. This was when the product was first introduced and there weren't many reviews out yet. I received it a week later and started using it right away!! The first thing I noticed was there was no irritation at all. It glided on very smooth and felt smooth while applying. It absorbed fast and well with a very light delicate botanical scent. I have been using it two time per day and have noticed a slight difference in how my skin reacts to outside elements. It has smoothed my dry areas while not adding oil around my nose. It's a winner in my book. This is a new staple for me!
