Reviews about Concentrate with Vitamin B3

In general, the serum is good. I am currently undergoing systemic therapy, so I decided to try this product based on my dermatologist's recommendation as an additional moisturizer. However, it tends to dry out my skin, probably because I didn't apply enough. Other than that, I think it is a good basic product.

Disappointment :(

I had a sample, and it had an amazing effect after using it a few times, so I bought a full-sized jar. However, even though the consistency is different in the larger version, it is thicker and the effect is not the same. It simply moisturizes easily and feels slightly sticky.

Before this, I was using La Roche V5, which was too greasy for me. And this larger version is very similar in consistency and effect. The only difference is the price.

It moisturizes well, I apply it on thermal water and seal it with a cream, and it lasts for a long time.

After the cosmetologist gave me a sample of this product, I realized that I couldn't live without it anymore. I applied the sample in the evening and in the morning, and the lifting effect was immediately visible!

However, after purchasing the full-sized jar, there was no effect at all.
