Does not irritate sensitive skin plus amazingly fast results.
Update: This product deserves the 5 stars. I began using this in late March 2026. It is now mid-late June 2026 and I can confidently say that this is giving me the benefits of retinal without any of the side effects I normally experience. My skin is clearer, brighter, softer, and just looks very healthy. Results are subtle and gradual over time. I can confidently say that this product works and I don’t know what kind of Hoodoo they put in here to make it so gentle but has not caused a single blemish, no rosacea flares while using this, and my skin looks and feels great. I’m an Aveda grad, I know quality skin care and you absolutely don’t have to pay enormous amounts of money. OTC retinol products are mostly all within the same range of strengths (either mild or moderate). There’s simply no reason to spend $100 on a serum when you can purchase a lower cost serum that offers the same results. One note here about retinol vs retinal(this product contains retinal vs retinol: retinal is a form of retinol that is biologically closer to retinoic acid. Retinoic acid is the only form your skin can use and OTC products require your skin to do the conversion. Some of the strength is lost during this conversion process. Retinoic acid is not available as a OTC product. It requires a prescription because it is much stronger. Basically retinol needs 2 conversions in your skin to create retinoic acid. Like this: 2 steps: retinol → retinal → retinoic acid. Retinal is 11 times closer to retinoic acid than retinol. It is usually more irritating than retinol because it’s stronger. This is simply not the case with this particular product. This is gentle and works faster than retinol. This is a quality product at an extremely reasonable cost. I’ve been using it since late March and I’m still not up for a refill and already seeing results. This is a keeper for sure. Original review: I have not been using this for long so I will be updating this review after 6 months. As of right now, this is one of the ONLY retinol based products that does not trigger my rosacea. I use it with heavy moisturizers. I was previously using ROC serum stick which triggered my rosacea just using it twice a week. When paired with a good moisturizer this does not disrupt my skin barrier. This is extremely important because I’m not going to keep using anything that triggers acne like pustules on my face. I’d rather deal with wrinkles and signs of aging. I will update my review once I have either seen results or not seen results but I thought it was important to let others know that with proper skincare I am able to use this product even though I have very sensitive skin. I could not find information like this when I was considering purchasing the product. I’d also like to mention that the amount of product here is large. You could definitely use this on other areas aside from the face and not break the bank. None of this matters, of course, unless the product works. I can’t comment on that just yet but I will update my review after 3-6 months of usage.

As close to a miracle serum as you'll get
STOP THE CAR! Literally. You need to order this today. As an Amazon Vine participant, I get a LOT of skincare products to try. So much that my bathroom counter and closet are overflowing and it's worth celebrating when I actually use one up and get to throw the container out. Despite all that, I could not ignore these reviews after seeing an ad for it on Facebook. My intrigue got the best of me and I ordered it. Let me point out that I did NOT get this free through Vine. I ordered and paid for it just like you will and you will, (trust me on this). I kid you not...from the very first use I noticed a change in my skin. I've noticed it looks plumper, fuller, softer looking and the fine lines are lessening. It's NOTICEABLE! I'm just months away from turning 60. I was a serious latecomer to taking care of my skin. I've never had to. I've been blessed with zero acne my entire life and just normal skin with little wrinkles. Since Covid, where we have spent more time outdoors at home in the SW USA desert, I've noticed the wrinkles starting. Fast forward to trying this product...I've literally been using it just a few weeks. I received it on May 27th and as I write this, it's June 16th. I've been using it 2-3x a day. First thing when I wake up, I wash my face and then apply this to my face and neck (2 or 3 pumps) then after my shower I do it again along with my normal serums and moisturizers and then also sometimes at night before my face cream. My skin is glowing and youthful. I'm beyond thrilled with this product. I even had a coworker who hasn't seen me in months comment on how fantastic I looked the other day. I'm not saying this is a miracle serum, but it comes pretty damned close. One thing I'd like to point out is that some are saying the label indicates this should be refrigerated. My label makes no mention of this - I even pulled the full label off the bottle and there's nothing printed under there. *Shrugs* I popped on here to write this review and saw there's a $2.00 off promotion so I just scooped up that deal, even though I'm nowhere close to being at the end of the bottle - as others have said, this bottle is HUGE. LOVE LOVE LOVE this MEDITHERAPY retinal skin booster serum. This will be in my permanent daily routine forever.

Great Retinal Serum for a Smoother, Healthier-Looking Skin
I’ve been really happy with this serum so far. It has a lightweight texture, absorbs nicely, and doesn’t leave my skin feeling greasy or heavy. My skin feels softer and smoother after using it, and I like that it contains retinal, niacinamide, and centella asiatica. It feels gentle enough for my routine while still giving my skin a fresh, more even-looking appearance. The pump packaging is also convenient and makes it easy to use. Definitely a product I would purchase again!

Pretty good for a first time retinal user
Personally haven’t seen any crazy changes like they show in social media and I’m almost done with the bottle. That said, I did see a bit brighter and smoother skin. I also like the texture and application of the product. The best thing though is that I had no purging or irritation. I’m excited to try a stronger retinal or a low dose retinoid next.

Great! Been using for more than a year.
Works well and fast but gentle enough to not ruin your skin barrier. Pretty light weight so it’s easy to pair with other products. Absorbs nicely too. Keeps your skin soft and moisturized. I bought it many time. I told my mom to buy it, told my aunt to buy it. I also gift it to relatives, and they all loved it

Love this Product!
I started using Meditherapy Retinal Skin Booster in August. I've had better results from this product that other products I've used. My dark spots are truly getting lighter. My skin in not dry, or greasy from the product. The container is also much large that other products, so it lasts much longer. I'm very pleased with my results so far, so I already ordered another one.

You need to use it daily.
It is very lightweight, easy to use. Not sure of its effect on the dark spots. It may take a long time to see results.

works immediately and with continued use even better!
So far so good no irritation and I have sensitive skin! I keep mine in the refrigerator! And so far it has made my skin look more useful and I’m 60 years old, and I noticed less lines with this moisturizing serum! Also using it on my elbows and my arms and my chest , and my chest does not wrinkle up like it used to it anymore and it’s only been a week using this !

とにかくオススメ!
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!

0,01 % Retinal – ideal für empfindliche Haut
Ich finde dieses Serum wirklich gelungen. Besonders interessant ist für mich das Preis-Leistungs-Verhältnis: 150 ml im Pumpspender machen es zu einem sehr günstigen All-over-Retinal-Serum aus Korea, das man nicht nur im Gesicht, sondern auch großzügig an Hals, Dekolleté und Körper verwenden kann. Die wichtigste Information musste ich allerdings erst recherchieren: Das Serum enthält 0,01 % Retinal (100 ppm). Schade, dass die Konzentration nicht deutlicher angegeben wird. 0,01 % klingt zunächst wenig, hat für mich aber absolut seine Berechtigung. Gerade für Retinoid-Einsteiger, empfindliche Haut sowie Hals und Dekolleté finde ich eine niedrigere Konzentration sinnvoll. Bei Retinoiden ist mehr nicht automatisch besser – entscheidend ist schließlich auch, dass die Haut das Produkt verträgt und man es regelmäßig verwenden kann. Auch die restliche Formulierung gefällt mir sehr gut. Niacinamid steht relativ weit vorne in der INCI-Liste. Eine genaue Konzentration konnte ich allerdings nicht finden und möchte deshalb keine Prozentzahl behaupten. Dazu kommen Centella asiatica und verschiedene Centella-Bestandteile, außerdem unter anderem Beta-Glucan, Panthenol, Ceramide NP, Cholesterin und Vitamin E. Das finde ich als Begleitung zu einem Retinoid sehr schön. Besonders hervorheben möchte ich Glycerin. Dieser hervorragende Feuchtigkeitsspender wird meiner Meinung nach völlig unterschätzt und muss sich hinter der wesentlich stärker vermarkteten Hyaluronsäure keineswegs verstecken. Die Textur ist leicht und angenehm. Gerade für fettige Haut finde ich sie sehr passend. Durch das Glycerin ist das Serum direkt nach dem Auftragen ein klein wenig klebrig, was mich persönlich aber nicht stört. Bei trockener Haut würde ich anschließend definitiv noch eine Creme verwenden, da das Serum alleine dafür nicht reichhaltig genug ist. Generell gefällt mir der Ansatz von MEDITHERAPY: Eine durchdachte Formulierung muss nicht mit möglichst hohen Wirkstoffkonzentrationen überladen sein. Gerade bei empfindlicher Haut ist weniger manchmal tatsächlich mehr. Wer bereits gut an Retinoide gewöhnt ist und eine stärkere Wirkung möchte, sollte sich eher die MEDITHERAPY Retinal Skin Booster Cream mit 0,05 % Retinal (500 ppm) und 100 ml ansehen. Für Einsteiger, empfindliche Haut oder als großzügiges Retinalprodukt für Gesicht, Hals, Dekolleté und Körper finde ich dieses Serum mit 0,01 % Retinal und 150 ml aber wirklich empfehlenswert – besonders für den Preis.
