Melasma vs. Erythema Multiforme
Similarities:
- Both conditions can be triggered or worsened by sun exposure.
- They affect the face and other sun-exposed areas, especially in individuals with sensitive skin.
- Sun protection, especially using broad-spectrum sunscreen, can help manage symptoms.
Differences:
- Melasma is a pigmentation disorder that causes brown or gray patches on the skin, often due to hormonal changes and sun exposure.
- Erythema Multiforme is an immune-mediated condition that causes red or purple target-like lesions, often triggered by infections or medications, and can be worsened by UV exposure.
- Melasma is cosmetic, while erythema multiforme can involve systemic symptoms, such as fever and mouth sores.
