You can change the shape of eyelids like double eyelid patch, double eyelid clip and double eyelid surgery: double eyelids.
It looks more natural and compact after use, and it can be as big as you want. Some beginners find it inconvenient to use it, so just practice more. Plastic surgery first marks the size you want on the eyelid with a plastic stick attached to the eyelid, then applies a thin layer of glue on that mark, and finally presses the stick to open your eyes for a while before fixing it.
However, this method also has disadvantages. If the painting is not good, it is easy to see the white dander of glue, and the eyelids are stuck and can't be closed, so it is not easy to apply eye shadow. If the glue is not chosen properly, it will hurt to wash it off before going to bed at night. To sum up: choose good glue, don't buy bad glue just to save some money, it will do some harm to eyelids.
How to use double eyelid glue
Clean eyelids before makeup. Face the mirror, slant one eye, and draw a line 2-3 mm wide where you want with a pen tip dipped in double eyelid glue.
After squinting for about 5 to 10 seconds, the glue began to solidify. Gently press it under the glue with the attached fork, and then take it off to form natural lines. At this point, in order to better fix the lines that have been formed, keep your eyes wide open and stay awake for 5 ~ 10 seconds, which can help the glue achieve the most perfect effect.
When the lines are unclear or drooping, please apply the liquid repeatedly. Never rub or forcibly remove it by hand when rubbing. You should scrub with makeup remover so that the glue can be removed easily.
