In general, it is hard and quite unfair to generalize all algae as comedogenic. And here is why. Algae is one of nature’s most abundant sources of nutrients. In fact, there are more than 1 million species of algae living in every square inch of ocean water. These microscopic organisms provide us with essential minerals such as iron, calcium, magnesium, potassium, zinc, copper, manganese, phosphorus, iodine, selenium, and vitamin B12.
They are excellent source of omega-3 fatty acids, which help reduce inflammation and also help maintain healthy skin by helping prevent dryness and irritation. The world of algae offers a tremendous and relatively untapped potential of bioactives from three branches of macroalgae (seaweeds) such as green (Chlorophyceae), red (Rhodophyceae), and brown (Phaeophyceae). We also have the microalgae that is a diverse group of microorganisms such as prokaryotic cyanobacteria (blue algae). Several of the macro and microalgae biocomponents have been shown to have high potential for anti-inflammation, anti-aging, skin-whitening, UV protection, boosting collagen synthesis, anti-oxidant, anti-microbial, and anti-viral properties.
