Does Botox last longer/have better effects on older or younger people? (Photo)

The effects of Botox generally last about 4-6 months.  The actual duration depends upon the dosage, location of injection, and how your body responds.  I would avoid all further cosmetic injections until the effects of your previous injections have completely worn off.  Then you can reassess your appearance and determine your needs.  Good luck!

The higher the dosage, the longer Botox can last. That being said, it may not last another 8 months. Botox typically lasts 3-4 months. That being said, fillers and lasers may be a good choice to for the desired results you want with your eyes. See an expert. Best, Dr. Emer

Hello and thank you for your question!

I'm sorry that you're not currently happy with your results. From my experience, patients who receive botox regularly - it appears that the botox does have a more lasting effect. Here's why. 

1. Botox prevents muscle contraction- if you don't use a muscle - it atrophies. So if you've had botox in the exact same muscles for 10yrs- it's like not using your leg muscle for 10yrs- it's going to be weak. 

2. weak muscles require less botox - so the same amount of units injected will have more of an effect

3. botox effects last until the medicine is washed from the receptors- this is different on everyone but usually is 3-5mo is the average- of course their are outliers on either side of this curve. 

I don't know what the symbol is below the right eye of this drawing- it appears that may have hit the zygomaticus major/minor muscle complex which could attribute to cheek ptosis or asymmetrical smile. The nasal injections can also contribute if not done perfectly. 

Give it some time - this information will hopefully provide you with ideas about what you want done for next time. 



God bless and Good Luck!
