I want to use breast firming cream to lift up my boobs, is it gonna work? (photo)

There are no exercises,
injections, supplements, foods, or creams that will noticeably increase breast
volume or lift the breast. Most often, implants are used to augment the breasts
of patients with good skin quality who lack breast volume. For patients with
both a lack of volume and sagging breasts, a combination of a breast lift and
augmentation (mastopexy augmentation) can address both issues. A detailed
examination will help delineate the best surgical treatment. Consultation with
a surgeon certified by the American Board of Plastic Surgery would be the next
best step.

Thank you for your question. The short answer to your question is no, firming creams will not help to firm or lift the breasts. Surgical intervention is the only way to address droopy or lax breasts.

Any structural change requires surgery. No creams, lotions, ointments, oils, massages, yoga et all, including magic potions can result in breast firming. Do not be swayed by what they promise.

Sorry, to my knowledge and experience there is no firming cream that will make a significant difference in your breast's skin laxity or droop.
