MARINE INGREDIENTS
compared to conventional extraction methods for synthetic or land plants-based ingredients.
Applications in skin care products Seaweed-derived ingredients have become a key component in a variety of skin care formulations, offering targeted benefits for different skin needs. One of the most popular applications of seaweed in skin care is in face masks, particularly hydrating and soothing formulations. Rich in polysaccharides like alginates and
fucoidans, these masks create a protective film on the skin, locking in moisture while delivering antioxidant and anti-inflammatory benefits. They are especially effective in sheet masks, overnight masks, and clay-based detox treatments, helping to reduce redness and replenish hydration levels. In anti-ageing formulations, seaweed extracts
are incorporated into serums, eye creams, and firming creams due to their ability to stimulate collagen production and combat oxidative stress. Brown algae, in particular, are known for their high content of phlorotannins and carotenoids, which help prevent premature ageing by neutralizing free radicals and improving skin elasticity. For daily skin care, seaweed-derived
ingredients play a crucial role in moisturizers, cleansers, and toners. Their hydrating and skin-replenishing properties make them ideal for maintaining long-term skin health while supporting the skin’s natural barrier function. Additionally, their ability to regulate
melanin production has led to their inclusion in brightening creams, dark spot correctors, and tone-evening treatments, offering a natural alternative to traditional depigmenting agents. Sun protection is another area where marine
ingredients shine. Some species of seaweed contain UV-absorbing compounds, making them valuable additions to sunscreens and after-sun treatments. Their photoprotective and antioxidant properties not only help shield the skin from damage but also support recovery after sun exposure, reducing inflammation and oxidative stress. Incorporating seaweed into post-procedure
skin care has also gained traction, particularly in products designed for skin repair after chemical peels, laser treatments, and microdermabrasion. Their soothing and anti-inflammatory effects accelerate recovery, minimize irritation, and reinforce the skin’s natural healing process.
Other seaweed activities When we talk about seaweeds, they can be categorized into three distinct groups—brown, green, and red—each with unique skin benefits.
Brown algae (Phaeophyceae) Brown algae are particularly rich in phenolic compounds and carotenoids, which are powerful antioxidants that protect the skin from oxidative stress caused by environmental factors like UV exposure and pollution. Brown algae also contain fucoidans,
compounds known for their deeply hydrating and anti-inflammatory properties. These attributes make brown algae ideal for soothing dry, sensitive, or irritated skin while providing long-lasting hydration. The richness of

fucoidans further contributes to brown algae’s role in reducing inflammation and promoting skin resilience.
Red Algae (Rhodophyta) Red algae are well-known for their anti-ageing properties, which help maintain skin elasticity and reduce the appearance of fine lines. These algae are also a natural source of UV protection, making them valuable for inclusion in anti- ageing and sun care products. By supporting the skin’s natural defences against sun damage and promoting collagen synthesis, red algae play a key role in maintaining youthful-looking skin.
Green algae (Chlorophyta) Green algae are celebrated for their high mineral content, which aids in strengthening the skin barrier and promoting cell regeneration. Rich in antioxidants, green algae help combat oxidative stress and protect the skin from damage caused by free radicals. These seaweeds are commonly used in protective and revitalizing skin care products, where they help to invigorate the skin and promote a healthy, glowing complexion.
Market trends: the rise of sustainable skin care The global cosmetics industry is increasingly embracing sustainability as a core value. According to the Top Global Consumer Trends 2025 report by Euromonitor International, brands with tangible sustainability initiatives grew 1.5% more than their non-sustainable competitors in 2023. This trend is particularly pronounced in the beauty and personal care sector, where sales of sustainable products exceeded $120 billion in the same year. The market for seaweed-derived cosmetic
ingredients is also experiencing rapid growth. A 2024 report by Transparency Market Research valued the global market at $500 million in 2023, with a projected annual growth rate of 6%, expected to reach $900 million by 2034. This growth is driven by consumer demand for eco- friendly and effective skin care solutions. Today’s consumers are more informed and
conscientious than ever before. They prioritize products that not only deliver results but also align with their values, such as environmental responsibility and ethical sourcing. In response, cosmetic brands are increasingly incorporating natural, sustainable ingredients like Ascophyllum nodosum extract into their formulations. This shift is not only meeting consumer demand but also driving innovation in the industry.
Conclusion While innovation in skin care often focuses on advanced synthetic ingredients, nature continues to offer solutions that are not only effective but also align with the growing demand for sustainability. Ínclita Seaweed Solutions brings the forefront of innovation with InAlgae LIT, a breakthrough cosmetic ingredient derived from Ascophyllum nodosum. This high-efficacy extract not only targets
dark spots and redness but also provides antioxidant and anti-inflammatory protection, making it ideal for sensitive and UV- exposed skin. Additionally, the international certifications NATRUE and COSMOS reinforce the commitment to rigorous environmental and social standards, ensuring responsible production that combines scientific efficacy with sustainable practices. More than just a powerful active, it
represents a commitment to sustainable production, reducing the environmental footprint while delivering cutting-edge skin care benefits. As the demand for eco-conscious beauty continues to grow, solutions like this prove that science and nature can work hand in hand to transform the industry.
