Leaves your skin very soft
I have been using this twice a day for about a week now. I think I can see a difference in the brightness of my skin and my pores seem smaller. It leaves my skin soft and lasts all day. My face is not as dry as before . The price was very good and I will continue to use every day.

This stuff is amazing!
I was skeptical and I rarely leave glowing reviews (see my other Amazon reviews - I'm pretty picky!). I have used various forms of retinol, retinal, and prescription retinoids over the past several years. I am 51 and looking to fight discoloration and sign of aging skin. Prescription strength tretinoin made my skin very sensitive and rough due to irritation, and I often had to take breaks from it and downgrade to a gentle retinol serum, which gave minimal to no visible results. I started using OTC adapalene as a gentler option but still cannot tolerate it daily and was not seeing the more refinement and smooth texture that retinoids are supposed to deliver. I have only been using this for about 10 days, so things may yet fall apart, but so far I love this. My facial skin does feel slightly sensitive but it is not red, rough, or burning. In fact, my face is soft and glowy. I'm hopeful that it will give the more and discoloration results I want over time. Because of the great price, I've decided to use on my body, as well, and WOW! I have been using a popular overnight retinol lotion sold at most drugstores and had some success with it, but this has amped up my results. My neck an chest are smooth and soft. I also use on the backs of my hands and on my knees/lower legs. My hands are smooth and more even-toned, and my lower legs have stopped flaking and also feel smooth with no ingrown hairs. I alternate between this and the old lotion every other day. The lotion is more moisturizing but this has really given results. I'll update this review if things change but right now I am thrilled. Pros: Lightweight No obvious fragrance sinks in quickly not sticky or greasy RESULTS! Cons: Not very moisturizing - I layer it under a lotion or occlusive on my body

I am LOVING this product for my sensitive skin!
I just turned 60 and have been using this product for a little over a month. I am LOVING the results. I saw a review on TikTok and decided to give it a try. I am so happy with the results. I have seen an overall improvement to my skin. Hyperpigmentation fading, skin smoother and firmer. My pores are almost non-existent. I have been using my own skincare formulations for over 8 years, and this is literally the ONLY product I use outside of my own formulations. It gave just that extra boost I needed. I have always had sensitive skin, especially to fragrances, so I love the fact that this is unscented. I have had no issues with sensitivity and to be honest, I did not ease into the product like suggested. I use twice per day, right after I cleanse and tone and I use few drops of my oil blend after I apply the booster serum. I work from home, but if I plan on going outdoors at all, I do apply a sunscreen. That's it! My skin looks and feels great. I highly recommend this product and will definitely reorder.

Visible Results for Youthful Skin!
This serum is fantastic! The retinal formula is potent and effective at reducing fine lines and improving skin texture. It absorbs quickly and my skin feels plumper and brighter since I started using it. A high-quality addition to my skincare routine!

Great for sensitive skin.
This is an excellent option if your skin can't tolerate most other retinol/retinal treatments. This applies silky smooth and doesn't irritate my skin and I've not dealt with any peeling. My skin feels very smooth and hydrated. I will repurchase.

Best serum I have tried
I'm a skeptic. I've wasted tons of money on products that promised and delivered no results. I seen this product all over tic Tok and Facebook, read the reviews and decided to try it. I saw no real results overnight obviously. But with a week of constant use, I was slowly starting to notice a difference. It's has now been 2 1/2 weeks and I will say, I definitely notice a difference. I have old acne scars, keratosis pillarsis and I sometimes still break out. I am 40 now, so I'm also battling fine lines I want to prevent from getting worse. I have large pores and oily/dry skin. This serum does make you feel a little sticky at first, but a little goes a long way and it comes in a bigger bottle than most products for a decent price. I put this all over my body from my face to my feet. It has balanced out my skin, it is more clearer, smoother and I have even noticed the scars are not as visible as they used to be. It does not irritate my skin, in fact it's even made the keratosis pilaris look better on my arms.. It has made my feet softer too. I will be purchasing another bottle for sure.

Use if you want a radiant skin
This feels luxurious and effective. My skin looked smoother and more radiant with regular use, and it absorbs nicely without irritation. A great option if you want to step up your skincare routine while still being gentle on your skin ✨

Sehr gutes Produkt, das auch mit hervorragend von Yuka bewertet wurde. Bei schlechter Haut brennt es etwas, aber dennoch kann man schnell Verbesserungen erkennen, die Haut heilt schneller ab. Ich bin sehr zufrieden, für den Preis habe ich gleich zwei gekauft!

Bought this based on reviews and description which states 0.00 irritation, in the past I have reacted with Retinol products especially around the chin, jawline area, my skin starts off itchy and tingly and after a few days it goes red, puffy and then eventually very dry and flaky, I chose this because it promised no reaction, sadly in my case this was not true as I still reacted exactly the same, another product that didn’t deliver and more money wasted

初めて使った翌日の朝、肌がふっくらして目元の皺がない! 使いはじめは日を空けて使用との事ですが、私の場合ピリピリしたり反応がなかったので、毎晩使用しています。 使っていて1番嬉しかったのは、お風呂上がりに脇の皺やポツポツに1プッシュずつ塗り込んでいると、1週間くらいで随分キレイになってきました!効果抜群です! お値段もお手頃なので、身体の気になるところにはこれからも塗りこんでいます。 同じ様な悩みがある方、とにかくオススメです!
