The Real Deal
As a guy in my late thirties, I have invested a lot more into skincare over the last year and I have tried myriad products, typically mid-range/affordable to very high-end and this retinal skin booster is one of my favorites. I’m new to retinoids, and I am grateful to have found this early on in my journey.Despite the strength of retinal vs. retinol, I prefer this serum to the retinol I was using before. I think it is kinder to my somewhat sensitive skin and it really does give my skins boost! I will say that I have not yet used this more than two nights in a row, but I plan to do so now that we are entering the winter months. But I will say that living in the high desert that I have not experienced any issues or increased sensitivity, but I am mindful of sun exposure and daily spf 50. But this serum works! My skin looks refreshed s d brighter after one night of use. My skin looks and feels great and after washing my face the next morning, my skin is neither dry nor greasy, but well balanced. It also does well with layering of other products without becoming sticky or heavy. I see this on sale often, but even if it’s not it is still reasonably priced for the results it delivers. Dk yourself(and your skin) a favor and give this one a shot. I recommend it to a lot of friends and I would highly suggest that you try it, too, if you’re looking for an accessible and wallet friendly way to level up your skincare routine.

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:LightweightNo obvious fragrancesinks in quicklynot sticky or greasyRESULTS!Cons:Not very moisturizing – I layer it under a lotion or occlusive on my body

If you have Rosacea this is a must!!!
If you have Rosacea this is a MUST!!! I have tried EVERYTHING!!! Up to chemical peels, hydro facials you name it… but nothing seemed to help. Then I started researching. Came across the ingredients that are listed in this bottle and decided to try it. Huge difference!!!!!! Keep it in the refrigerator and use right after you wash and tone your face. This is a game changer for me. I have suffered for YEARS with rosacea that I absolutely hated! The redness, blotchy, muddy appearance was so so embarrassing. After using Selsum blue to wash my face, I use glycolic acid as a toner then use this right out of the refrigerator and it’s heavenly!!! No more muddy, red, irritable skin for me! Just soft and smooth! Highly effective. Hydration and baby soft skin without the sticky feeling! So easy to use. Just a pea size amount goes a long way!

Wow
I’ve been using this on dark patches of skin near my elbow. It definitely lightens the uneven skintone. It does not occur over night, it needs to be part of your daily routine. Sometimes, if I remember I apply it twice a day. I caught this item on sale, so a win for me lol. I’ll keep using it but everyday my dark patches/ uneven skintone improves.

So far so good!
I’m 51 years old and been using this retinal serum a couple of times per week for 2 weeks now. I’ve experienced no issues. It feels great going on – no stickiness. I’ve been using 5 pumps in the evening and it’s more than enough to cover my face, neck, shoulders, chest and back of my hands. I haven’t seen a difference in fine lines or hyperpigmentation just yet, but hoping to eventually. Since I haven’t had any issues with it for 2 weeks – I’m about to start using it every night. I’ve already added it back to my cart and hoping it will be on sale on Black Friday so I can get another.

No sensitivity like retinol, but still amazing results!
This. Is. Amazing. My skin hates retinol. Doesn’t matter how low of a concentration or how I ease into it. More than 2 times a week, my skin revolts. Not this stuff though. I am using it every single night and my skin looks amazing. Tightened pores, even tone, less wrinkles, glowing. I use this and an eye cream and I’m good to go. I don’t even use a night time moisturizer. It even helps with acne! This bottle also lasts a long time. When I run out, I will definitely be buying this again.

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!

とろみのあるテクスチャーで肌馴染みが良いです。使用して半月ほどになりますが、肌が保湿されてなめらかになり顔全体がトーンアップしたように感じます。
