Abstract            : Cosmetic botulinum toxin injections usually cause discomfort to the patient. Using a small needle causes less pain compared to using a large needle,¹ but a drawback is the price. A 30-G needle costs 2 THB while a 32-G needle costs 15 THB. The physician must decide when a needle is to be discarded. In one study, a 30-G needle was changed after approximately four to six punctures because of increased skin resistance.² A 32-G needle is less painful than a 30-G needle because of the 25 percent smaller diameter of the 32-G needle.³ Instead of relying on individual tactile sense, we compared the penetration forces of two needle sizes to decide when to change the needle during botulinum toxin treatment.
