I used this serum months ago 2 1/2 applied for the first time and after 5-6 weeks noticed that something is happening. Up to 3 times I have actually used every night serum. My Häärchen the lower eyelid are now a little longer and a little denser. The upper lashes are now a bit longer, but that a new eyelash splendor will develop will probably wishful thinking :) really good to see the whole thing first when applying mascara, I also think that the lashes have become a little brighter by the serum as it is also in the description. Initially, the serum was burning something in the eyes, which are, however, quickly. Normally I would give it 5 stars, but the fact that I paid for 3 months currently 74 for it and are now 100 requires for this is an impertinence and a star deduction worth.
