Injecting stronger Botox solution. Is this safe?

Thank you for your question. It may be the case that over time you have developed a resistance to Botox, making it less effective. However, that is a somewhat rare occurrence. If you have tried other neuromodulators, you might find that combination treatment with dermal filler helps around the eyes for a liquid eye lift. There are also other treatment options outside of injectables like laser treatments and RF microneedling that can help with fine lines and wrinkles and is safe to use with dermal fillers. Consult with an experienced, qualified injector to determine what treatments and combinations are right for your cosmetic goals.

Hello and thank you for your question. It is always best to see you face to face for a consult and examination however in this case yes a more concentrated botox dilution if use by an experienced clinician is safe to do. I hope that helps answer your question. Always seek an experienced and qualified medical professional for these treatments. Very best wishes

I doubt that a more concentrated dose of Botox will make a difference if the number of units is the same. It is also possible that after 10 years, you have experienced some normal age-related changes that Botox is not the best option for. Get an opinion from a plastic surgeon to see if a brow lift or eyelid surgery is indicated.
