Night Face Serum - Biotherm Blue Retinol Serum Night
I am very satisfied with the effect! Mimic wrinkles became noticeably less visible after just 2 weeks of use, and my complexion looks well-groomed and even. The product is very economical and, in my opinion, definitely worth the money!
I bought this product in Europe. After the first application, a layer of skin came off my face in the morning. The brightening effect and even tone were noticeable within a couple of days, as the small wrinkles disappeared. There is no redness or any other issues! My skin is neither oily nor dry. I never had acne, so my skin was already in good condition. The effect is simply amazing! I also applied the serum on my entire face and under my eyes.
I was given this serum as a gift, but I didn't carefully read the instructions before using it. It clearly stated that it should not be used every day and should not be applied around the eyes, which is important! On the 5th day, I developed a red spot on my cheek that felt like a burn. So, please be attentive before using it.
