Heightening stickers sold online have little effect on height. Human growth and development are closely related to genetic and nutritional factors. Teenagers will naturally grow taller in the growth and development stage, and grow rapidly after puberty. Generally, after 18 years old, their growth will slow down. Of course, it's not very absolute. After all, everyone's development process is different, and there is no obvious effect on promoting height growth with heightening stickers. If teenagers are underdeveloped, they can help children pay more attention.
Growth and development are natural laws. People's bodies grow fastest in adolescence, and most of them don't grow taller in adulthood. Parents and friends should pay more attention to using scientific methods instead of relying on products such as heightening stickers. It is not very reliable to use heightening stickers to increase height.
