Figure 6: After 28 days of using a 2% Sarcodia suiae extract scalp serum, subjects exhibited reduced dandruff, less greasy scalps, and visibly diminished areas of scalp redness
Furthermore, 96.97% of participants believed
the product had oil-controlling benefits and reported no abnormal hair loss (Figure 7). A separate five-day, in-house test was also
conducted to evaluate anti-acne performance using a different base essence containing 2% Sarcodia suiae extract. The subject, who had suffered from long-term acne, showed visible improvement after three days, with the acne nearly completely subsiding by day 5. No stinging or irritation was reported during the testing period (Figure 8).
Conclusion The red grape algae Sarcodia suiae, cultivated in the clean, nutrient-rich waters off eastern Taiwan, has demonstrated considerable potential as a multi-functional cosmetic active ingredient. Through a series of in vitro assays, the extract exhibited strong antioxidant, anti-inflammatory, anti-allergic, sebum-regulating, and antimicrobial properties— targeting multiple root causes of scalp issues. In a third-party clinical trial, a scalp essence
containing 2% Sarcodia suiae extract as the sole active ingredient significantly improved scalp condition within 28 days—reducing oiliness, dandruff, and redness. Notably, 100% of subjects reported satisfaction, with no abnormal hair loss or irritation observed throughout the trial, confirming both its effectiveness and excellent skin compatibility. Importantly, the extract is produced through
an eco-conscious cultivation and extraction process, further aligning with sustainability and clean beauty values. As scalp care continues to gain prominence in the personal care industry, Sarcodia suiae extract stands out as a next- generation marine bioactive ingredient with clinically proven, multifunctional benefits.
