You may want to avoid products with this ingredient if you have acne or blemish-prone skin. It has a comedogenic rating of 3 (on a 0-5 scale) which means it may clog pores. This may not be a concern if you aren’t struggling with pimples but you’ll want to keep an eye on it.

What Is Corallina Officinalis Extract?

Corallina officinalis extract comes from corallina officinalis, a red algae found on rocky shores around the edges of tide pools. It can be ground up for use in skincare to exfoliate the skin, increase cell turnover, and help regulate oil production.

The common name of corallina officinalis is coral weed. It forms calcium carbonate deposits within its cells, making it harder and less pliable than other seaweed.

Applying dried seaweed powder to your face may not sound appealing, but it does offer significant benefits.

Corallina Officinalis Comedogenic Rating

This red seaweed extract has a comedogenic rating of 3, so it may clog pores. Even though exfoliation is often good for acne and blemish-prone skin, this ingredient may clog your pores. Proceed with caution if you’re currently struggling with pimples or blackheads!

Corallina Officinalis Comedogenic Rating

As you may have heard, comedogenic ratings are far from perfect. Ingredients are generally tested in high concentrations on the back of humans. The testing used to be done on rabbit ears but that process was banned. Everyone’s skin type is different and the pores on your back are different from your face. But the main flaw in comedogenic testing is that it generally focuses on specific ingredients applied in high concentrations. When this ingredient is mixed with other effective skincare ingredients, it may not have the same pore-clogging attributes.

However, the comedogenic rating system serves as a useful gauge for assessing the skincare ingredients we use, albeit imperfect. Knowing that this ingredient is a 3, you know that there is a higher chance of it clogging your pores than other ingredients with lower comedogenic ratings. Products with this ingredient may not trigger breakouts and acne but it’s worth considering if acne is a concern.
