Its emollient properties make it a popular ingredient in moisturizers, where it helps to hydrate and soften the skin. Meanwhile, its antioxidant and skin conditioning benefits make it a valuable addition to serums, where it can help to improve skin health and appearance.
Benefits and Uses
In this section, we will delve into the officially recognized benefits and uses of Rhodosorus Marinus Extract:

Regular use of products containing this extract can result in a noticeable improvement in skin texture and an overall healthier appearance.
Emollient
As an emollient, Rhodosorus Marinus Extract works by forming a protective layer on the skin’s surface that helps to lock in moisture.
