Science
Mechanism of Action
This extract functions by attracting and retaining moisture, acting as a humectant within cosmetic formulations to enhance skin hydration. Concurrently, it serves as a skin conditioning agent, maintaining the skin's optimal state. Its rich composition of polyphenols, phenolic acids, and flavonoids, extrapolated from research on related Hemerocallis species, suggests it actively combats oxidative stress, reduces inflammation, provides moisturization, calms irritation, and supports the skin's natural regeneration processes.
