Top product, I have been using it for years! Over time, the skin transforms! Be very careful with its use, it needs 4-5 drops at night only together with moisturizer and definitely sunscreen in the morning! Start using it once a week and when your skin builds tolerance you can use it more often. The only negative for me, since I have oily skin, is its texture. Although it says it is a serum, it is clearly an oil and I don't find it very pleasant.

It is definitely not suitable for oily skin prone to acne. I started getting internal pimples on my chin, and when I stopped using it, my skin calmed down.

In my case, it caused intense sensitivity in areas of the face, like a very mild burning sensation.

One of the best retinols I have tried. It is more than worth its money. It comes in an oil form and personally I use 3 small drops, one on each cheek (be careful not under the eyes) and one on the forehead. It makes my skin very smooth. I peeled after some time but this is normal. In general, retinols require caution, occasional use at first and then, once the skin gets used to it, daily use and ALWAYS sunscreen before going out in the sun.

Be careful with retinoids and always read the instructions for use because they can cause burns and dryness. This particular one is strong. At €10 there is no better retinol.

It did not cause me the slightest irritation. I believe it works; after a few months of use, my face is noticeably more refreshed. Lately, it seems that, in combination with the soap I use, it somewhat dehydrated my skin. With more diligent moisturizing, everything is fine.

I have sensitive skin and yet it did not irritate me at all, while other retinols, pharmaceutical ones, had caused me intense peeling. However, perhaps the lack of reaction also indicates its ineffectiveness on my skin (50 years old), but even worse, its heavy, oily texture, which with 2 drops does not absorb until the next morning, caused me pimples all 3 times I tried to include it in my routine.

If you are under 40 years old I think this is exactly what you need, there is no need to go for a more expensive retinol. This particular one is like a thin oil and that might be the only reason some people may not like it in general. It does an amazing job, the results are visible even the next morning

Very good retinol, I have used several without results and they dried out my face even though I have oily skin. This one is in oil form, it absorbs into the skin in a few minutes without leaving greasiness and at the same time it also moisturizes.

Whatever I say about this product is an understatement... it noticeably reduces wrinkles from the first applications that I can hardly believe it!!!

Very good retinol. It is in oil form but it doesn't stick, absorbs very quickly. It has never irritated my skin and I use it almost every day.

Great attention is a strong term and can burn your face. At first, until the skin gets used to it, it needs to be used once a week and then you gradually increase. Excellent term makes the skin radiant! I recommend it!

Unfortunately, it turned out to be too strong for my skin. I had used various retinol serums as well as retinol creams in the past and none had caused me irritation. This particular serum started to make my face very red and peel intensely from the first applications. I tried to give it time by applying it a few times a week and mixing it with my moisturizer at night, but I still had the same symptoms. I also feel that it does not absorb easily and leaves a greasy feeling on the skin.

I'm getting it for the second time! My skin was peeling initially after use. It took a couple of weeks for my skin to get used to it. It leaves my face oily. It sits well under makeup, but I don't like it on its own. I apply it every other day, every night. I will buy it again! I like it!!

I didn't find it moisturizing enough. It also creates a peeling effect that I'm not sure is justified.

It does the job, I have seen a difference in my face. Of course, I have also changed my moisturizer and generally my routine. I use it once a week because it's summer and I'm a bit scared of it.. I don't like its scent. I think it burns my face a little, at least in the first hours of application.

Rita, 30 years old: It does a pretty good job, clean retinol I use 2 times a week before I go to sleep, it really is an oil and not a serum. I have seen a big difference in 1-2 months. And as for the price, it's unbeatable, just like the rest of the products from the same company, unbeatable especially for the exfoliation that cleans very well. You should try it, just like the salicylic acid, the anti-wrinkle, with niacinamide and hyaluronic acid, all perfect from this company. In 3 months, my face has changed a lot, no more pimples, and it tightens, hydrates, and shines in everything, and at a price that you don't even think about

At first, I was peeling so I was using it every other day. Once my skin tolerated it, I started using it every night. It has a greasy texture so it needs 3 to 5 drops. No more. And moisturize after. I had wrinkles for many years and all dermatologists were telling me expensive methods to get rid of them. After 1.5 months of using retinol, they all disappeared!

Before purchasing, you should know that:

1. It is not a serum but an oil (the ordinary is also to blame for calling it a serum), so obviously it does not absorb like a water-based product.
2. It takes a long time to see results from retinol - depending on each skin/case.
3. If you are not accustomed to retinol, it is better to start with a product that has a lower concentration, for example, retinol 0.15 / 0.3 or at most 0.5, and also not use it daily. If your skin tolerates it well, you can use it every night.
4. SOS SOS Always use sunscreen daily.
5. Do not overdo it, especially with this particular product which is strong - 2 to 3 drops are enough (it absorbs faster if you don't overdo it)

Very greasy and oily texture. Heavy on the skin and not absorbed. This concentration, one of the highest on the market, still hasn't given me any negative result to say that it exists. I started using it every night and a sufficient amount. Not even to irritate my skin or feel anything from using such a high concentration.

It may get the job done, but it doesn't absorb like other serums. It leaves a heavy feeling of greasiness

It seems to do the job, sometimes after frequent use it peels off my face and interrupts its use for a while. Now I made the mistake and bought another brand, but as soon as it finishes, I will return to this one.

I bought it for the chronic freckles I have, and some of them have turned into patches. I don't know if other products I use (Nivea Cellular Luminous 630 Anti Dark-Spot Serum and Cream) are to blame, but from the first two times I applied it, some patches that I have had for a while have weakened to the point of almost disappearing. My skin is brighter to the point where photos look like I have applied a filter. In the first applications, my skin peeled quite a bit, but that was expected. Also, the scent is not very pleasant, but we are talking about a vitamin, not a cosmetic cream. I will definitely continue to use it.
