How old are you now? If you are young, you can learn about it through diet therapy. Now there are some dietotherapy methods on many beauty websites and magazines. You can try. Of course, this process can be longer, but it is safe. If you are over 30 years old, I think surgery is undoubtedly a faster way, but you should be cautious when doing cosmetic surgery. Breast augmentation products and the operation of the surgeon are very important. If you want to have surgery, it is recommended to choose some good hydraulic silicone as breast prosthesis. Now it may be Meg in the United States, and it is said that the rejection rate is very small. Even if rejection occurs, it can be taken out in time, which has relatively minimal harm to life safety and chest lesions. You can go to an authoritative plastic surgery institution for more consultation. Don't rush to make a decision. Be sure to define your position and don't be fooled.
If your boyfriend or husband doesn't care about the size of your breasts at all, then my last advice is not to use the knife easily. Feelings do not depend on whether you are perfect or not.
I hope I can help you.
