Lichen sclerosus is a long-term condition, so symptoms often improve with treatment and return once it stops. That pattern is how the disease behaves, not a sign your treatment has failed. The thinning, cracking and narrowing happen from ongoing inflammation under the skin.
Next Steps
Topical steroid treatment usually needs to continue long after symptoms settle, so inflammation stays controlled. If the narrowing is affecting you day to day, a procedure can sometimes help once the skin is calmer. Please see your gynaecologist to review your current treatment and plan next steps.
Health Tips
This condition needs regular follow-up, since long-standing untreated patches can occasionally need a biopsy to rule out skin changes.
