I really like the Polar Night Renewal Serum, it blends in my skin nicely and not greasy. I love how my skin has been feeling lately since I used it.
Store owner replied: We're so glad you are enjoying the serum! It's clinically proven to reduce wrinkles after 30 days. We know you'll be happy with the results the more you use it.
As a male in the late 30s, I didn’t have much of any skin care routine but tried this night serum for the past week and have been waking up and noticing my face is smooth, more firmer, and pores have seem to be smaller! The product itself is a non-oily texture with a balanced viscosity that isn’t too thick or thin. I find one pump covers my face with ease that absorbs an ample layer within 1-2 minutes so applying a moisturizer can be done shortly after. The presentation and bottle also have an elegant, regal touch which evokes an excitement to use it repetitively. I’m truly happy it’s shown results within a week. A good rest is everything, and knowing that I have an ethical and powerfully formulated night serum for my face is assuring to know it’s working hard when I’m not. Starting the day with your skin feeling hydrated and supple radiates a positive confidence and that goes a long way. I would highly recommend this night serum for your skin care as it’s been an effective improvement for me!
I saw a notable difference immediately! My skin was softer, plumper. So happy to have stumbled upon this gem.
Store owner replied: Your skin looks so healthy and happy!
This is in order of most recent to first photos I think the progression and difference is pretty dramatic and noticeable. I’m tickled at the results!
I was able to order this during pre-launch and have used it consistently for the last 2 weeks. It completely replaced my other treatment products and has become a staple. My skin looks bouncy, radiant, and clear. At almost 44, I couldn’t ask for more! A+++++ serum!
It’s been only 4 weeks. I love the feel of this product and its hydration. I live in a very dry climate. Fingers crossed.
It’s my nighttime go to. I wake up with soft replenished skin.Skin has a nice radiance.
I love the product , but the amount of product is too small. It is difficult to pay so much for so little!
My skin looks and feels healthier than before use.
My skin seems to be loving the formula. There was an initial couple spots, but my skin adjusted to it. I use two pumps every night and the bottle seems to be lasting a decent amount of time. The initial full size I was sent had a packaging issue and the product leaked all out. It was super easy getting a replacement sent out to me. I will be repurchasing this product.
I ended up going with an entirely new routine/regime that includes more clinically powerful actives etc.. It was a nice product to use, didn't notice any significant changes as I may not have used it long enough.
Store owner replied: Thank you so much for sharing your feedback! The serum you have is our trial/travel size, which provides approximately a 2-week supply. Our clinical testing was conducted over a 6-week period, and while many people may begin to notice changes sooner, the formula is clinically proven to deliver results with consistent use over 6 weeks. We’d love for you to experience the full benefits of the formula, so please don’t hesitate to reach out if you’d ever like to try the full size! 💛
Love the product and ingredients! Thoughtful packaging for refills. Great customer service too! Excited to continue using for results.
Store owner replied: We're so happy you're enjoying the formula and the experience!
Best night moisturizer I have used, it goes on smoothly and doesn’t feel greasy
I am very pleased with the results this product has provided for my skin. It has been a truly positive experience, particularly given its gentle nature on my sensitive skin.
I wasn’t always successful at applying the serum by 10pm but I don’t see or feel any improvements to my 69 year old skin.The bottle is aesthetically pleasing, and I appreciate that it’s refillable.
This was an unexpected perk bcs of the size. I use it almost everywhere night - I’m loving it!!!
I love this it does exactly what it claims and it is very smooth and non irritating. I will re order it again.
Love quality of product!
I definitely noticed an improvement in the quality of my skin, vitality and hydration. I am interested in seeing longer term results. Overall what I enjoyed more than anything was the experience, the light scent and texture of the serum each night was something I looked forward to.
Love it, feels amazing on the skin and adds a terrific layer to my nighttime routine.
Store owner replied: Love that you added our Renewal Serum to your nighttime routine!
Love the way my skin feels every morning after using nocturnal the night before.
The product is great! Unfortunately, it didn't even last a month.
This is a good serum. I can’t tell whether it is working because I didn’t take a “Before” picture. At 67, I’m not sure anything except plastic surgery could help me.
Thanks for the amazing product! My skin has never looked better
Best serum on the market in my opinion. My skin has never looked better and never felt better!
Great product. 2 pumps is all I need on a daily basis. Feels nice and clean. My skin feels better already.
I loved this so much after trying years of multiple serums, have had professional facials for years too. I’d highly recommend. My only complaint is that the one portion, despite following the recommend amount- only took me so far and ran out much faster than other serums. For the price point, I’d expect it to last enough for showing first results at the 4-6 week mark. I ran out in 3 weeks.
Love the hydration.
Great product!
I absolutely Love your Polar Night Serum. My skin is definitely changing, it’s more defined, feels & looks refreshed as well as so soft. Once I turned 50 I was looking for a treatment that your treatment does. I wish I could use it during the day as well. My skin drink’s it right up and I love that there is no sticky feeling. You have truly made a one of a kind Skincare Product that does it all for one’s face. Next week I am placing another order. 💚🌘

My skin has never looked more smooth and even toned
No huge difference in the look or feel of my skin.
My skin looks more hydrated.
It’s an amazing product! Your skin will be more than greatful receiving a collagen shot like that:)!!!! It makes your skin feel hydrated and with this kind of glow that u couldn’t imagine! For sure anyone will become obsessed…..:)
Great!
Nocturnal is the first serum I’ve been serious and consistent about. I saw the results almost immediately and am very impressed with how gentle the product is-pretty much the only thing I care about when adding something new to my routine. The brightness is a bonus! Thankyou!
It's great! I wish the price was lower though. I would try other products if the prices were lower. I like the night serum a lot.
Nothing special. Too expensive for nothing special.
Product only lasts a few weeks; it’s not really long enough to get a decent idea of how it works.
Store owner replied: Hi Jamie! Our travel-size offering is 15ml by design, which is ideal for short trips, on-the-go use, or for customers who want to test the formula before committing to a full size. While it’s a smaller format, it still delivers the same high-performance results and premium formulation as the standard size. (A little goes a long way!) That said, your feedback is incredibly valuable to us. We’re constantly working to improve and your input helps us make more informed decisions for future offerings. If you’re finding that you love the product and would like a longer-lasting option, we’d love to recommend our full-size version, which offers better value and extended use.
My skin feels so hydrated and looks so smooth! Great product with great results!
