I have been using it continuously for the past 4 years and I wouldn't change it for anything. I apply it in the morning over my day cream and then I put sunscreen on top. If I want to wear makeup, it spreads perfectly and lasts without making my skin oily or settling on dry areas. It is a high-quality antioxidant and helps with anti-aging. I am 45 years old and have combination skin with oily and very dry areas. The EUK 134 0.1% Serum balances my skin and not only has it stopped time in the past years that I have been using it, but it has also faded existing wrinkles. 10/10, I wouldn't change it for anything.

Simply wonderful! It matched perfectly with my skin (combination). It made my skin look smooth and for some strange reason, I tanned more easily! The best for summer!
