Science
Mechanism of Action
This ingredient nourishes the skin by providing essential vitamins and minerals, while its polysaccharides significantly enhance moisture retention, supporting both elastin and collagen synthesis. It acts as a powerful antioxidant, neutralizing free radicals from environmental aggressors like pollution and UV, thereby protecting the skin's collagen structure. Undaria Pinnatifida Root Powder also exhibits anti-inflammatory and soothing effects, which can diminish the appearance of fine lines, wrinkles, and hyperpigmentation. Its fucoidan content aids in epidermal hydration and firming, and its rich protein and vitamin profile supports anti-wrinkle and anti-pollution benefits, promoting skin detoxification and regeneration.

Key findings
- 01 In vitro studies demonstrate potent antioxidant capacity for Undaria pinnatifida polysaccharides (UPPs) at a concentration of 0.5 mg/mL.
- 02 Fucoidan extracted from Undaria pinnatifida showed 73.55% iron-chelating activity at 500 µg/mL in vitro.
- 03 Crude polysaccharides from Undaria pinnatifida sporophyll (UPE_8P) exhibited a significant cell protective effect, maintaining 97.17% cell viability after H2O2 treatment at 400 µg/mL in vitro.
- 04 Root extracts of Undaria pinnatifida demonstrated superior in vitro antioxidant activity, with DPPH, ABTS+, and FRAP IC50 values of 1.51 mg/mL, 3.31 mg/mL, and 2.23 mg/mL, respectively.
- 05 While specific optimal percentages for Undaria Pinnatifida Root Powder are not defined, Undaria Pinnatifida Extract is commonly incorporated into cosmetic formulations at 0.1-5% and is considered well-tolerated across various skin types, including sensitive skin.

Safety
Safety Profile
The Cosmetic Ingredient Review (CIR) Expert Panel concluded in 2018 that there was insufficient data to determine the safety of 'Undaria Pinnatifida Root Powder' under the intended conditions of cosmetic use. Conversely, 'Undaria Pinnatifida Extract' was deemed safe in 2019 for current cosmetic applications. The extract generally holds a low hazard rating (typically 1) from EWG, with minimal concerns for irritation or toxicity, though it notes potential contamination from toxic impurities like iodine, arsenic, and lead. Rare allergic reactions may occur in individuals sensitive to seaweed or iodine; patch testing is recommended.
