and severe skin allergies. It is better to stay away from such products. You can exercise to increase muscle
bulk which can give good shape and some projection to breast. There are few safe and effective treatment for breast augmentation. Fat fill where we take fat from abdomen or thighs and inject into breast is a scarless treatment. And other option is implants
which can give you the desired shape and size. You can consult in private to discuss the pros and cons
of each treatment.
