After Lichen Planus heals, it commonly leaves behind dark marks called post-inflammatory hyperpigmentation, which are harmless but can take time to fade; the most effective approach is regular sun protection (daily sunscreen with SPF 30 or more) to prevent further darkening, along with gentle skin care and doctor-recommended creams such as mild depigmenting agents (like azelaic acid, kojic acid, or retinoids) that help gradually lighten the spots. Avoid harsh scrubbing or home remedies that can irritate the skin and worsen pigmentation. These marks usually improve slowly over months, not days, so patience is important, but if they are very persistent, a dermatologist may suggest treatments like chemical peels or laser therapy for faster results.

Oral Lichen Planus is a long-term (chronic) condition, and at present, there is no permanent cure, but it can be effectively controlled so that symptoms are minimal or absent for long periods. Treatment mainly focuses on reducing inflammation and discomfort using doctor-prescribed topical medicines (like corticosteroid gels), maintaining good oral hygiene, avoiding triggers such as spicy foods, tobacco, and stress, and having regular dental check-ups. Many people experience periods of improvement and flare-ups, and with proper care, the condition can remain stable and manageable. It is also important to follow up with a doctor because, although rare, long-standing cases need monitoring for any changes.
