Skin Conditions Treated by Dr. Koushik Lahiri
Dr. Lahiri's areas of clinical expertise encompass a wide range of dermatological conditions.
1. Acne and Acne Scars
Acne is one of the most common skin concerns, affecting teenagers and adults. Persistent acne can result in inflammation, pigmentation, and scarring. Appropriate dermatological treatment can help control acne and reduce the risk of permanent scars.
2. Vitiligo and Pigmentation Disorders
Vitiligo is a condition in which the skin loses pigmentation, resulting in lighter or white patches. Dr. Lahiri has contributed to the development of vitiligo surgery and laser surgery in India.
Treatment options depend on the extent, activity, and characteristics of the condition.
3. Psoriasis and Eczema
Chronic skin disorders such as psoriasis and eczema can cause itching, irritation, inflammation, and considerable discomfort.
Dermatological evaluation helps determine appropriate treatment and long-term disease management strategies.
4. Hair and Scalp Disorders
Hair loss, scalp infections, and other hair-related problems can result from several underlying causes. Identifying the cause is essential before selecting a treatment plan.
5. Fungal Infections and Skin Allergies
Fungal infections and allergic skin reactions are common concerns, particularly in hot and humid environments.
Correct diagnosis and appropriate medication are essential, as the indiscriminate use of steroid-containing creams can sometimes aggravate fungal infections.
6. Dermatological and Laser Surgery
Dr. Lahiri has particular expertise in interventional dermatology, including vitiligo surgery and laser procedures. Treatment suitability depends on the patient's clinical condition and individual requirements.
Contributions to Dermatological Research
Beyond treating patients, Dr. Koushik Lahiri has made significant contributions to dermatological research and medical education.
His work includes publications and books covering topical corticosteroid use and misuse, pigmentation disorders, fungal infections, and laser dermatology.
A professional biography prepared for the 2025 International Congress of Dermatology lists 166 publications, eight books, and 31 book chapters, highlighting his longstanding academic involvement.
Why Consult a Qualified Dermatologist?
Skin conditions that appear similar may have very different underlying causes. Self-medication, particularly with steroid-containing creams, can delay diagnosis or worsen certain conditions.
A qualified dermatologist can help patients understand their diagnosis, evaluate suitable treatment options, and develop a personalised care plan.
Whether the concern involves persistent acne, unexplained pigmentation, recurring fungal infections, psoriasis, vitiligo, or hair loss, timely consultation can support better skin health.
