Lichen Planus — Conditions

What is Lichen Planus?

A chronic inflammatory autoimmune skin condition characterized by purple polygonal papules

Can appear on the skin, oral mucosa, and nails, accompanied by severe itching. The exact cause remains unclear.

Main causes & characteristics

Lichen planus is believed to involve an autoimmune-related reaction in which the immune system mistakenly attacks skin cells, though the exact cause has not been clearly established. Stress, certain medications, and some viral infections are also mentioned as potential triggering factors. A characteristic feature is that it can appear not only on the skin, but also on the oral mucosa and nails.

How to manage

Avoiding scratching and soothing the skin with moisturizer to minimize severe itching and irritation is recommended. Using gentle, low-irritant products and reducing stress through lifestyle adjustments may be helpful. Consulting a dermatologist is recommended if violet-colored papules spread widely or are accompanied by oral or nail involvement.

Good to know alongside

Lichen planus is often compared with and discussed alongside autoimmune skin conditions, psoriasis, and oral mucosal diseases.

Everyday care tips

On nights when itching is intense, briefly soothing the skin with a cool, damp cloth and reducing mucosal irritants — such as alcohol and spicy foods — may help.
