Seaweed Dermatitis

Seaweed dermatitis is a skin condition caused by contact with various types of seaweed, which can lead to uncomfortable symptoms and irritation. In this article, we will provide simple, easy-to-understand explanations for the types of seaweed dermatitis, its causes, symptoms, diagnostic tests, treatment options, and related medications.

Types of Seaweed Dermatitis:

Seaweed dermatitis can be classified into several types, each associated with specific seaweed species. The most common types include:

1. Green Seaweed Dermatitis: Caused by contact with green seaweeds like Ulva and Enteromorpha.
2. Red Seaweed Dermatitis: Triggered by contact with red seaweeds such as Chondrus and Gracilaria.
