First, when people get old, collagen on their faces will gradually lose, especially after the age of 25, and at the same time, eye fat will also lose, which will naturally become double eyelids or even triple eyelids. In our life, we can see that many elderly people have more double eyelids than when they were young. So this is a natural factor.

Second, it becomes a double eyelid by unnatural factors, that is, artificial means. But the artificial means mentioned here are not cosmetic surgery, double eyelid cutting and the like. But by sticking double eyelid stickers. The specific method is to stick double eyelids in the same position every day. A short month can be shaped, and a long year or so can also be shaped. One disadvantage of this method is that it is easy to relax the eyelids, but as long as you are careful when you tear off the double eyelid stickers every day, there will be no eyelid relaxation.

Third, this is a method with the least probability of becoming a double eyelid naturally, that is, gently scratch your eyelids with your nails every day, scratch when you think of it, and stick to it.
