Hi there, I love when this question gets asked as I am someone who actually does research into this area. Although I agree with the majority of the points made by others here, i do disagree in some respects. Botox is a medication that has the primary effect of stopping your muscles from moving. This is why after you get it, you have trouble moving parts of your face. If done properly and into the correct muscles, it can soften wrinkles and even prevent them from forming. Someone young like you, if you had botox between your eyes as well as on the sides of your eyes you may get a 'lift' that elevates your eye brows and helps reduce some of the extra skin. Its not always perfect, but certainly a treatment to try as it is very safe. Now, i have conducted research looking into the effect of botox on skin elasticity and we now know that botox may actually be doing more than simply effecting muscles. interestingly, if you were to put cells that are responsible for the collagen and elastin in your skin in botox, they actually produce more of these youthfull skin products. This is one reason why people who get botox between their eyes often notice the wrinkles fade. Their skin is more elastic and youthfull. I must be clear, that botox does not "tighten" skin in the way you hope. One option for this is using a treatment called Radiofrequency skin tightening, this may help with saggy skin. But please, talk and get assessed by a trained physician. Hopefully this is usefull and interesting. Dr James P.
