*The maximum score is 100 points

Our practical test of the eyelash serum has shown that the manufacturer keeps its advertising promises. With regular use , we noticed a significant thickening and lengthening of the eyelashes, although patience and perseverance are required to achieve visible results. In addition, the serum did not cause any irritation or allergic reactions to the eyes, even in people with sensitive skin. Application is extremely easy and quick, without making the lashes sticky.
The eyelash serum is preferably applied after cleansing the face . First, the eyes should be thoroughly cleansed with an oil-free cleanser to remove any residue from make-up or skincare products. The serum is then applied like an eyeliner along the upper lash line . Make sure that the serum is also applied to the skin in this area, as this is where it should take effect.
After application, the serum should be left to work for a short time before applying other skincare products or make-up. The serum is quickly absorbed and leaves no sticky residue on the eyelashes. Application can be repeated up to twice a day to achieve optimum results.
The vegan formula of the serum contains no silicones or preservatives, instead relying on natural ingredients such as caffeine. This also makes the product attractive for environmentally conscious consumers. Overall, we can recommend the eyelash serum due to its effectiveness, compatibility, ease of use and high-quality ingredients.
