I suggest you go to the hospital for a check-up first and see the results. The doctor will give you advice.

Because good back is generally effective between the ages of 6 and 28, but the effect of each age stage is different. 6 to 18 has the best effect and can correct the correct sitting posture for three months. 18~28 years old, because the bone development is gradually improved, the effect will be relatively slow, but it is definitely the age stage suitable for correction, and the normal sitting posture can be restored in 3-6 months. After the age of 28, it takes longer because the bones are basically shaped. This will test your patience and resilience. It usually takes a year.

I'm 23 years old. I used it on my back for half a year. Now I put on my old hunchback. However, wearing a good back is only effective for acquired habitual hunchback. If you have a congenital hunchback, it's no use putting on your back. Of course it is useful, but it will take a relatively long time to correct this age. In addition, you must stick to it when you wear it. If you wear 1 month, don't wear it for half a month. There are many people, so it is important to stick to good habits.
