What is PEG-12 and what does it do in skincare?

PEG-12 is a synthetic compound used in skincare as a humectant, meaning it helps the skin retain moisture. It also functions as a solvent and emulsifier, improving the product's consistency and ingredient distribution.

Is PEG-12 safe for sensitive skin?

While generally considered safe, some individuals with highly compromised or sensitive skin may experience mild irritation from PEGs, especially at higher concentrations or if the skin barrier is damaged.
