International Beauty Day is observed worldwide every September 9. This annual event was initiated by the Russian section of the International Committee of Aesthetics and Cosmetology (CIDESCO), which was founded in 1946 in Brussels, Belgium, and is now headquartered in Zurich, Switzerland. The day celebrates both inner and outer beauty and highlights the significance of the beauty industry. CIDESCO encourages participation in the campaign by sharing personal definitions of beauty on social media using the hashtag #InternationalBeautyDay. Local sections of CIDESCO also organize various events in their respective countries to promote the observance. The organization aims to establish and uphold high standards in beauty and spa therapy, facilitate the exchange of professional knowledge, and create certified training centers.
