Abstract
BACKGROUND: Botulinum toxin (BTX) has been used cosmetically with good clinical efficacy and tolerable safety.
OBJECTIVE: This randomized, double-blind, split-face clinical study aimed to investigate the efficacy and safety of intradermal BTX in patients with rosacea.
MATERIALS AND METHODS: Twenty-four participants were enrolled and randomly given intradermal injections of BTX and normal saline in both cheeks. Clinician Erythema Assessment (CEA) score, Global Aesthetic Improvement Scale (GAIS) score, skin hydration, transepidermal water loss (TEWL), melanin content, erythema index, elasticity, and sebum secretions were evaluated at baseline and 2, 4, 8, and 12 weeks.
RESULTS: On the BTX-treated side, the CEA score significantly decreased and the GAIS score significantly increased. The erythema index decreased at Weeks 4 and 8. Skin elasticity was improved at Weeks 2 and 4 and skin hydration, at Weeks 2, 4, and 8. However, TEWL and sebum secretion did not show significant differences.
CONCLUSION: Intradermal BTX injections significantly reduced the erythema on both cheeks and improved skin elasticity and hydration, but not TEWL and sebum secretion. Intradermal BTX injections reduced erythema and rejuvenated the skin effectively and safely in patients with rosacea.
