Lithothamnion calcareum extract is derived from a species of red algae found primarily in the cold Atlantic waters off the coasts of Ireland and Iceland. This calcified seaweed is known for its exceptionally high mineral content, particularly calcium and magnesium, along with trace elements such as iron, zinc, and selenium [1]. These minerals play crucial roles in various skin functions and are essential for maintaining healthy, youthful-looking skin.

The extract's effectiveness in skincare is largely attributed to its unique mineral composition and bioavailability. When applied topically, these minerals can be readily absorbed by the skin, supporting cellular processes and enhancing the skin's natural barrier function. Research has shown that Lithothamnion calcareum extract can significantly improve skin hydration and elasticity [2]. A study published in the International Journal of Cosmetic Science demonstrated that a cream containing this extract increased skin moisturization by 27% after just four weeks of use [3].

Furthermore, the anti-aging properties of Lithothamnion calcareum extract are particularly noteworthy. The high calcium content helps stimulate collagen production, which is essential for maintaining skin firmness and reducing the appearance of fine lines and wrinkles [4]. Additionally, the antioxidants present in the extract, such as polyphenols and phlorotannins, provide protection against free radical damage, further contributing to its anti-aging effects [5].
