Science & Benefits

PEG-4 is a low-molecular-weight polymer that acts as a humectant and solvent. It is highly hygroscopic, drawing water into the stratum corneum, and provides a very light, watery texture. It is zero-comedogenic and zero-irritant. In acne-safe formulations, it serves as an excellent delivery vehicle for active ingredients while providing a base level of hydration that leaves the skin feeling refreshed rather than occluded.
