Great! For some time now and after losing 20kg in a few months, my face has become thinner and wrinkles have appeared around my eyes. I have been using this serum for two weeks and I noticed yesterday (even though I was not particularly focused on it) that these wrinkles had diminished considerably. So, the first day, I tested this gel alone and it pulled the eye contour, accentuated the wrinkles and you could clearly see the demarcation of the product. So I tested it again the next day by adding my eye contour cream just after applying and massaging this serum a little... Meh: this time, it was the cream that started to "pill" after a few seconds and make a white demarcation. Same again, the next day, I tested this serum by adding my eye contour oil afterwards and there, it was perfect. The product no longer pulls, no longer pills and does not make a demarcation. I recommend this recipe.
