Breast reduction surgery, known as mammoplasty, can be expensive and is inherently risky as all surgeries are. Non surgical breast reduction products and treatments are less effective, if they work at all, but offer a more affordable alternative. The concern is determining which ones actually work from the majority of products that are simply a waste of time and money.
Weight Loss
For patients who are overweight, losing body fat can result in a smaller breast size because there is a lot of fatty tissue in the breast. It won’t help reduce the size or amount of glandular tissue so, depending on the anatomy of the individual’s breasts, losing fat might cause the breasts to look flat which would require a breast lift to correct.
Breast Reduction Pills
Breast reduction pills are not only ineffective they can pose a health risk depending on the ingredients in the pill. These productions usually contain herbal products that can be marketed as effective for breast reduction but it is highly likely that there is no scientific evidence to support those claims. These pills are a waste of money and can be dangerous so it is best to leave them on the drugstore shelves.
Breast Reduction Creams
Most topical solutions are ineffective ways to achieve breast reduction without surgery. Breast reduction creams might work like skin creams that tighten and tone skin. 
This can produce a tighter, contracted feeling but does nothing to actually reduce breast size. While the possibility remains that there could be an effective product, there has been no word on anything being remotely reliable.
End Breastfeeding
It is commonly known that pregnancy and breastfeeding will enlarge the breasts. Once the mother stops breastfeeding the breast will attempt to naturally shrink to its normal size. However, the effects of this change will usually leave the breast appearance flat or deflated.
Breast Reduction Bras
While these are merely clothing accessories that can make large breasts less noticeable it does nothing to actually reduce the size. The extra support can make the breasts more manageable so it is easier to go about regular activities with fewer physical limitations and inconvenience of having excessively large breasts.
Unfortunately there isn’t much that can be done to reduction breast size non-surgically. Some products might seem to be effective but usually it is due to the placebo effect or the delusion of the user. Exercise and weight loss is a good idea for any person so there is no harm there. But taking pills or using creams that can cause unforeseen health problems. Always talk to a physician before trying any medicinal product regardless if it is herbal based or a pharmaceutical.
