Kairbossom is designed for strengthening, firming and toning up of breast muscles, resulting in an increase in your breast size, prevents sagging breasts, corrects under developed breasts and importantly beautifies your shape. This product usually takes about 6-8 weeks to see an improvement; which is normally ½ to 1 cup increase in bust size. The first function of Kaibossom Herbal Breast Massage Oil is to decrease the venous return, thus making blood more readily available to breast tissue. It also gives more time to the cells to absorb the nutrients, fats and hormones. This results in growth of the size of fat cells, hence a bigger bust-line.
