I used very little product right at the lash line on both my upper and lower lids. Wouch! I woke up the next day and my both my lids and the skin above and below my eyes were reddened. When I washed my face the skin around my eyes got really red. I let my eyes calm down a day or two and tried using an even smaller amount on just the top eyelash line. Same thing. Even the skin around my bottom lids became red, but to a lesser extent. I'm super bummed. I don't think I can use any of the 2 tubes I bought (it was on sale, I got 2). I tried MaxeyLash in the spring of 2020 and did not have this reaction. But, the product came out of the tube in a very sticky, gelatinous form. These new tubes have thin, easy to apply product. Maybe I got an old, degraded tube with the very first order las Spring? Who knows. But, I can't use these two tubes I have now. Very sad :( :(
