Yes, frequent exposure to diesel can be the cause, as it strips away the natural oils from your skin, leading to dryness, wrinkles, and skin damage over time. The most important step is to avoid direct contact by wearing protective gloves at work. Use a thick moisturising cream or emollient several times a day, especially after washing and at night. If your skin becomes very red, itchy, or cracked, please consult a doctor for further treatment.

Your symptoms could be due to a condition called dermatographia (skin writing), in which the skin reacts strongly to light pressure or touch, causing swelling and redness. Allergies, certain medications, or underlying medical conditions may also contribute. Avoid scratching or rubbing your skin, use gentle, fragrance-free moisturisers, and take antihistamines (such as cetirizine or loratadine) if advised by a doctor. It is important to see a dermatologist to confirm the cause and receive appropriate treatment.
