When you think of algae, the first image that might come to mind is the green stuff floating in a pond. However, algae is much more than just a plant found in water bodies. Algae, both macro and micro, are powerhouses of nutrients and have been used for centuries for their medicinal and health benefits. In recent years, the beauty industry has harnessed the power of algae to create skincare products that offer a multitude of benefits. In this article, we will explore the wonders of algae, its health benefits, and how it can transform your skincare routine.
Understanding Algae: Macro vs. Micro
Algae are simple, photosynthetic organisms found in water and on land. They are classified into two main types: macroalgae and microalgae.
Macroalgae: Commonly known as seaweed, these are large, visible to the naked eye, and found in marine environments. Varieties include kelp, sea lettuce, and red algae. They are rich in minerals, vitamins, and antioxidants, making them an excellent skincare ingredient.
Microalgae: Microscopic single-celled organisms found in both fresh and saltwater, such as spirulina and chlorella. Despite their small size, they are nutrient-dense and rich in proteins, vitamins, and essential fatty acids.

Types of Algae in Portugal and the Azores
Portugal, including the Azores, has a rich variety of macro and microalgae due to its long coastline and favorable marine conditions.
