Even out the texture of the skin with toner, apply the required amount of the product to the forehead and both cheeks. Gently pat for better absorption.

Before the first use, we recommend conducting an allergy test. Find out how to do a patch test correctly🙂

i didn’t see any effects
5/12/2026

it absorbs very fast and nice under make up, but i haven’t noticed any effects whatsoever, so i’d skip it next time

The best thing so far in my 35th year!
1/19/2026

The best at the moment in my 35! From the first days, the result may not be visible, but in the middle of the jar I realized that the skin became denser and less reactive to external stimuli, uniform skin! For me, this is an indispensable item in care at the moment!

neutrally
1/18/2026

It's supposedly great, but I don't see any significant effect. It has a neutral scent, absorbs quickly, and feels great in the morning as an extra step before cream, but after a month, I haven't noticed whether this serum does anything.
