Video content above is prompted by the following:

Several key risk factors increase an individual’s likelihood of developing vitiligo, with genetic predisposition being the most significant factor. Family history of vitiligo substantially raises risk, indicating strong hereditary components in the condition’s development. Autoimmune thyroid disease frequently occurs alongside vitiligo, creating a well-established connection that prompts dermatologists to routinely check thyroid function in newly diagnosed vitiligo patients. Environmental factors also contribute to risk, including exposure to caustic chemicals and skin injuries that may trigger the autoimmune response.

Early vitiligo diagnosis primarily benefits patients by limiting the total skin area requiring treatment, making repigmentation more achievable when fewer patches need restoration. However, conflicting research exists regarding whether early treatment versus delayed treatment significantly impacts pigment recovery success rates. The distinction between active and latent vitiligo remains debated in medical literature, with some studies suggesting active vitiligo responds differently to treatment than long-dormant patches.

Ruxalitinib cream stands as the only FDA-approved topical treatment for vitiligo, working through JAK inhibition to reduce inflammation and protect melanocytes from immune system destruction. Other treatment approaches include systemic steroids, oral JAK inhibitors and excimer laser therapy applied two to three times weekly to stimulate repigmentation. For extensive body involvement, full-body light box therapy provides the same therapeutic wavelengths as targeted laser treatment. All treatments focus on reducing inflammation to allow melanocyte survival and regeneration.
