Topicals can help rejuvenating the skin and give a better shape.
I am not sure what's available in your country (I am from the UK). Some other users may give you more help about that.
You can also try goggling something like "breast firming cream" and see if anything pops up around you. They are usually available in pharmacies in most countries.
#Edit:
I just remembered that people from the US, UK, and Italy have managed in the past to order from Biovea and that they had some good results with their gel. I personally bought their Progesterone gel years ago. They sell products with bioidentical hormones so be careful not to exceed the dosage suggested on the bottle.
