3 weeks later I feel like I have new skin. At 60, my skin was dry and had quite a few fine wrinkles. Now it is fresh. It breathes.

4 stars for the excessively small amount of each "drop." Other than that, it is the best retinol product I have tried, perhaps also due to the vitamin E

Honest effort for single doses of retinol. Cumulatively in the 4 sachets it seems like an expensive product, but for travel it is just fine

Lightweight, absorbs well, but if you apply cream on top, it sometimes forms clumps. I use it at night as a serum and my face is always unrecognizable in the morning. Soft, firm, and radiant. I am lucky to not have wrinkles, only some fine lines, and I have been using it preventively for years now. If I haven't developed deep wrinkles at 37, it is partly due to these ampoules.

It is indeed an effective product, at least in terms of treating discoloration and small marks after acne, as well as during outbreaks. Due to the presence of Panthenol (B5), it is gentle on the skin and did not cause any irritation or peeling. This is also my first experience with retinol. As for the negatives, it does not fully absorb and leaves a greasy film on the skin, which needs to be left for a while and lightly wiped off before applying any other serum or cream, otherwise the retinol will transfer around the mouth area where it should not go!!! Also, as time passes, the scent becomes a bit unpleasant. However, after 2 months of use, I have already seen a difference, so with careful application, it does its job and more. As for wrinkles, I don't have an opinion yet because it takes at least 3 months of use to see results, but overall, I see my skin in very good condition since I started using it. I must say that the next morning, my skin feels extremely soft.
