"No PEGs" is not an ingredient itself but a formulation descriptor indicating the absence of polyethylene glycol (PEG) compounds, which are commonly used as emulsifiers, surfactants, and penetration enhancers. Products labeled this way appeal to consumers concerned about potential PEG impurities (such as 1,4-dioxane or ethylene oxide) or skin sensitivity.
| Reported effect | How often | Notes |
|---|---|---|
| Skin irritation | Rare | Reactions are attributed to alternative emulsifiers used in PEG-free formulations rather than to the absence of PEGs. |
| Contact allergy | Rare | Substitute surfactants or preservatives in PEG-free products may occasionally cause sensitization. |
| Reduced product stability or texture issues | Uncommon | Not a true side effect; PEG-free emulsifiers can alter feel or shelf stability, indirectly affecting tolerability. |
Frequencies reflect typical cosmetic use reported in the literature, not a guarantee for your skin.
