Fractional Micro-Needle Radiofrequency and I Botulinum Toxin A for Primary Axillary Hyperhidrosis

A Comparative Study for Efficacy and Safety Between Fractional Micro-Needle Radiofrequency (FRM) and Intradermal Botulinum Toxin A for the Treatment of Primary Axillary Hyperhidrosis

Because of the limiting data about an efficacy and safety of fractional radiofrequency for the treatment of hyperhidrosis, this study aim to compare clinical efficacy by Hyperhidrosis Disease Severity Score (HDSS) between Fractional Microneedle Radiofrequency device and intradermal Botulinum toxin type A injection for the treatment of primary axillary hyperhidrosis. The secondary objectives to determine the improvement change of iodine starch test, total amount of sweat production by trans-epidermal water loss (TEWL), patient's satisfaction and their quality of life by Dermatology Life Quality Index and side effect between the groups.

Exclusion Criteria:

Active bacterial or fungal infection over tested area / axillae

• Pregnancy and breast feeding
• Previously underwent the surgical treatment such as radical resection of sweat glands for primary axillary hyperhidrosis
• Currently being treated with intradermal botulinum toxin type A injection at axillary area for less than 12 months
• Currently being inserted the cardiac pace maker or any other internal electronic devices
• Secondary hyperhidrosis caused by hyperthyroidism, drug induced, abnormal autonomic or neurological disorder that affect sweat gland
• Allergy to botulinum toxin type A
• Known contact allergy to iodine
