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.

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

The Best I
This is my fourth purchase of this. I like it so much better than my moisturizer I had to share with friends. This product does exactly what it says in product description. Reasonable and it actually does great things for your skin. My skin is firmer , brighter and my foundation goes on smooth and stays all day. Great product.

Very gentle on the skin
I’ve been using the Meditherapy Retinal Skin treatment and I’m genuinely impressed with the results. The texture is lightweight, absorbs quickly, and feels soothing from the very first application. After a few uses, my skin looked noticeably smoother, more hydrated, and refreshed. It is gentle, no irritation, no heaviness, just a clean and comfortable finish. The packaging is also practical and hygienic, making it easy to use every day. I recommend it if you’re looking for a reliable, effective addition to your skincare routine.

A game changer for my skin
This has been a game changer for my mature sensitive skin. I use it every day and it really helps the rest of my products work better. The price is great and the quality cannot be beat. It is an auto ship for me and I will continue to buy it as long as it’s offered.

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.

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。
