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.
