Botox, Dysport and Xeomine, non work for me. What is an alternative?

True resistance to neuromodulators, such as Botox, Dysport, and Xeomin are rare and true antibiody development to these products is likewise extremely unlikely. More likely, lack of response relates to overdilution of the materials, improper injection technique and placement, or both. Nonetheless, in the twenty-three years since I began injecting Botox for aesthetic reasons, I have encountered individuals who do respond as well as would be desired. For such individuals, I have found The Nonsurgical 3D Vectoring Crow's Feet Llift to be especially useful--either alone or  combined with neuromodulator treatment.Using the principles of vectoring with volumizing fillers (see the Realself archives for a more detailed discussion of The Nonsurgical 3D Vectoring Facelift, The 3D Vectoring Necklift, and the The 3D Vectoring Browlift), the region over the bone within the fixed (nonmobile) area of the cheek directly in front of the ear is used as an access point to instill "strands," "strains," or cylinders of the volumizer in a fan shape distribution over the mobile crow's feet (periorbital) area and extending onto the cheek. Requiring only a tiny amount of local anesthesia to numb the entry points, the procedure is relatively painless and takes only a few minutes on each side to perform.As a rule, immediate smoothing of the crow's feet area is seen. However, as with the other Nonsurgical 3D Vectoring Lifts, continued improvement is anticipated over the next six to eight weeks as new, native collagen is synthesized in response to the presence of the injected material (neocollagenesis). Treating both the static and dynamic components of the problem tends to prolong the results of therapy beyond that which might be obtained with either therapy alone.

It is rare, but possible, to have a resistance to Botox, Dysport and Xeomin.  In my experience, if there is a resistance to one, there is a resistance to all.  Additionally, when I have seen resistance, it has been an all or none effect.  So, in your case when you say the effect is gone within in a couple of weeks, it is possible you don't have a resistance but need to alter the dosage.  

It would be highly unusual for you to be resistant for Botox, Dysport, and Xeomin.  It is more likely that the dilution or injection technique is contributing to your poor results.  Please consult a board certified dermatologist with a great deal of experience with Botox to evaluate you and inject the area.
