It's useless, but the effect is not very good. Needless to say, I am troubled. Later, I heard about this product, Acura Breast Booster, which has a good reputation. I bought it for a long time and tried it. Now I have used it for 4 weeks, and I have grown more than 3 cm. There is no discomfort and the skin is fair. I still insist on using it. I chose the right product this time!
