A. A white mark or patch below the nose that’s dry but not causing pain or itching could be due to a few different things. Common causes might include: 1. **Dry Skin**: Dry patches can occur due to environmental factors or skin conditions. Applying a gentle, fragrance-free moisturizer may help. 2. **Contact Dermatitis**: This can happen if the skin has reacted to a product or substance. Consider if any new products have been introduced. 3. **Tinea Versicolor**: This is a fungal infection that can cause lighter patches on the skin. 4. **Vitamin Deficiency**: Sometimes, a lack of certain vitamins or minerals can cause changes in skin pigmentation. 5. **Eczema**: This condition can cause dry, scaly patches on the skin. It’s a good idea to consult a dermatologist to get an accurate diagnosis and appropriate treatment.
