Science
Mechanism of Action
Ethyl citrates function as non-oily emollients, delivering a smooth, soft texture to the skin while optimizing product spreadability and absorption. They actively support skin hydration by providing and retaining moisture, effectively preventing dryness. Beyond skin conditioning, they serve as effective solvents, ensuring other active compounds dissolve and blend seamlessly, and act as carriers to boost ingredient penetration. Additionally, they contribute as preservative boosters, antioxidants, and film-forming agents.
