PEG-8 (polyethylene glycol 8) is a water-soluble polyether used in cosmetics as a humectant, solvent, and emollient that helps retain moisture and stabilize formulations. It is generally considered a base/formulation ingredient rather than a therapeutic active.

|---|---|---|
Mild skin irritation | Uncommon | Possible on sensitive or already compromised skin barriers. |
Allergic contact dermatitis | Rare | Reported mainly in individuals sensitized to PEG compounds, often on broken skin. |
Stinging or transient redness | Rare | Typically associated with damaged or eczematous skin. |
Systemic absorption concerns | Very rare | Relevant chiefly with application to burns or large open wounds, not intact skin. |
Frequencies reflect typical cosmetic use reported in the literature, not a guarantee for your skin.
