As hormonal changes reshape the skin’s texture and vitality, seaweed emerges as a natural ally — offering clinically proven support for radiance, resilience, and balance in menopausal skincare.
Menopause marks a profound transformation in a woman’s life. Beyond the internal hormonal changes, the skin itself becomes a canvas of these shifts, reflecting a decline in oestrogen through visible and often uncomfortable symptoms: dark spots, redness, heightened sensitivity, uneven tone, and loss of elasticity. For many, these changes affect not only their skin health but also their confidence and emotional well-being.
With more than 70% of women over 40 actively seeking skincare specifically tailored to peri- and post-menopause, and an estimated $22 billion annual spend by this demographic (Byrdie, May 2025), the need for effective, targeted, and sustainable solutions has never been greater.
InAlgae® LIT: A Seaweed Breakthrough for Skin Uniformity
Launched in the first half of 2025, InAlgae® LIT, by Ínclita Seaweed Solutions, is a next-generation cosmetic ingredient derived from Ascophyllum nodosum, a brown seaweed rich in bioactive compounds. Designed to offer advanced skin uniformity benefits, InAlgae® LIT works by inhibiting tyrosinase activity, the key enzyme responsible for melanin overproduction, and by neutralising nitric oxide radicals (NO•), which play a central role in skin redness and inflammation.
But beyond its expected role in pigmentation and redness control, recent clinical studies revealed an even broader relevance of this ingredient in menopausal skincare, particularly for women experiencing visible skin changes from this hormonal transition.
Clinical Validation with a Focus on Menopausal Skincare
Clinical studies proved the in vivo efficacy of InAlgae® LIT in reducing hyperpigmentation. A healthy adult panel of female volunteers aged between 36 and 70 years (mean age: 56.9), presenting facial skin hyperpigmentation and redness, applied a facial cream formulated with 2% InAlgae® LIT once daily at night for 56 days.
Skin pigmentation was monitored using the Mexameter™ MX18, measuring melanin index in both hyperpigmented spots and unstained areas to validate improvements in tone uniformity. Results demonstrated up to 33% reduction in melanin index after 8 weeks, with 90% of participants reporting visibly more even skin tone.
Clinical studies also proved the in vivo efficacy of InAlgae® LIT in reducing skin redness. A VISIA system was used to evaluate redness areas through polarized light photography, enabling precise assessment of skin features such as wrinkles, redness, and pigmentation spots. After 8 weeks of daily use, volunteers reported up to a 45% reduction in redness.
Although not the primary focus of the study, self-assessment results highlighted additional perceived benefits related to menopausal skincare:
- 90% reported improved skin elasticity and a visible reduction in wrinkle depth;
- 80% observed fewer blackheads;
- 90% noted smoother texture and overall improved appearance.
Together, these clinical results position InAlgae® LIT as a next-generation active ingredient — one that contributes to overall skin resilience and comfort during menopause. Its proven efficacy in menopausal skincare underscores the potential of seaweed biotechnology to deliver visible, multi-dimensional benefits that go beyond traditional cosmetic claims.
A Circular and Sustainable Production Cycle
The power of InAlgae® LIT lies not only in its clinical efficacy but also in its sustainable production cycle. Extracted from Ascophyllum nodosum, its cultivation requires no freshwater, arable land, or fertilizers, making it one of the lowest-impact sources of bioactive skincare ingredients.
The production cycle designed by Ínclita Seaweed Solutions relies on organic extraction methods and a biorefinery approach that ensures the entire seaweed biomass is valorised: bioactive fractions are extracted for high-performance cosmetics, while residual materials are repurposed in agriculture and other sectors. This circular model guarantees zero waste and significantly reduces carbon footprint, setting a new benchmark for environmentally conscious cosmetic actives.
As science and sustainability converge, InAlgae® LIT emerges as more than just a cosmetic active — it is a symbol of how marine biotechnology can reshape the future of cosmetics, especially in menopausal skincare. Clinically validated to address the visible skin challenges of menopause while produced through a low-impact, circular model, this seaweed-derived innovation empowers women to embrace midlife with confidence and radiance.
By uniting efficacy, natural origin, and environmental responsibility, InAlgae® LIT demonstrates that the next generation of beauty is not only skin-deep — it is also sustainable, inclusive, and profoundly aligned with women’s evolving needs.
