Why do Botox/Dysport/Xeomin related eyelid droop problems resolve quickly?

If botox generally lasts 3-4 months, why can a lid ptosis resolve within 3-6 weeks? Why does it wear off quicker in this area? Thank you for your time, any response would be greatly appreciated.

Glad you asked this.   This answer is that most eyelid droop isn’t really eyelid droop!!!  Most of these are misdiagnosed and are really eyebrow droop caused by over relaxation of the forehead muscles above the eye.  That relaxation causes the brow to droop and creates more hooding which is interpreted as eyelid droop.  Make sense?   True cases of lid ptosis are actually quite rare.

It wears off faster because usually the amount of Botox injected into those forehead muscles was quite small and so it wears off fairly quickly.   If a doctor or nurse injects way too much into the forehead muscles (frontalis muscle), it can last much longer and gives the forehead that unpleasant, very flat, “dead” look.

One of the best investments in your skin is your daily skincare. Why? Because you can prevent many problems with blotchy skin color, lack of glow, texture, some types of acne, and fine lines with good skincare products. You can also correct some of these problems with effective skincare products. Great skincare is often more expensive because quality ingredients are expensive. Some companies spend on research/development which benefits all of us and adds to the cost. Are they worth it? In general - yes! I have handpicked some of what I consider to be the best skin care products, and offer them for sale on SkinTour's shop. This is based on my team and I's testing and research at our clinic. Many of the products are in my own regimen. What could be better than using skin care products a dermatologist uses?!
