Will the nose of a girl of seventeen or eighteen narrow with age?

Don't! The narrow nose can only be operated on. But good living habits can be changed a little. For example, don't pick your nose often, don't eat anything that will get angry, and so on.

Will the upper lip become thinner with development?

Don't! Be careful not to bite or suck the upper lip to prevent the upper lip from thickening.

When the weight exceeds 90 kilograms, the chest is an airport. When the weight is less than 80 kg, is the chest as big as two coconuts?

That's bullshit！ Do not use chest products for external use or internal use, which will affect hormone levels and have a very bad impact on your development! Think about it, you don't want irregular menstruation caused by beautiful breasts! ? Women are still healthy! External use is not good, it may cause mammary gland hyperplasia in the future! Many breast cancer patients are breast hyperplasia patients!

You can also get breast implants when you are old, but that's expensive! You still have a chance to develop. I suggest trying a healthy way. For example, it is said that some foods can enhance breast. I recommend some for you: papaya and stewed pig's trotters with soybeans.
