Look Beyond My Skin: World Psoriasis Day 2026

World Psoriasis Day, observed each year on October 29, was launched by the International Federation of Psoriasis Associations (IFPA) in 2004 to give a voice to the more than 125 million people worldwide living with psoriasis and psoriatic arthritis. To mark this year’s observance, IPC joined the Latin American Society of Psoriasis and Dermoimmunology (SOLAPSO) and the Skin Inflammation and Psoriasis International Network (SPIN) to create a video series around the theme “Look Beyond My Skin,” featuring voices from all three organizations.

New Take Two videos will be featured each month, drawn from the Take Ten with IPC library and recordings from IPC symposia, with a link to the full presentation for each.
