Is there a serum that might mimic Botox?
It’s an interesting technical challenge because serums and creams only penetrate so far (not far) into the skin. A serum or cream would need to traverse the skin, subcutaneous fat and the fibrous layer on top of the muscle to get into where it needs to be —- the center of the muscle! Also, how do you insure safety?? What if someone accidently rubs it into their eye? You can see the difficulty. It may be a ways off still. Dr. I
