Great questions! Treatments for vitiligo can work on two fronts — slowing or stopping the spread, and helping restore pigmentation. Here's a quick breakdown:
Stopping the spread:
- Topical treatments like Opzelura (ruxolitinib) may help slow or stop active spreading relatively quickly
- Sun protection also plays a role in preventing further depigmentation
Restoring pigmentation:
- Phototherapy (NB-UVB light therapy) is one of the most effective options, with a 65–75% success rate
- Topical treatments like Opzelura can stimulate repigmentation, especially on the face
- Results are slow — think months, not weeks. As one MyVitiligoTeam member put it, "It's not a microwave situation, it's a Crock-Pot situation"
It's worth knowing that repigmentation results don't always last permanently. Maintenance treatment is often needed to hold onto progress. Regarding sun exposure timing — it looks like the question got cut off! Generally speaking, uncontrolled sun exposure isn't recommended as a substitute for proper phototherapy.
A dermatologist specializing in vitiligo can guide safe sun exposure based on the UV index for the day, skin tone, and current treatment plan. Even low UV days can cause burns on depigmented patches, which could actually interrupt treatment progress.
