"Anti-pollution" is a marketing category rather than a single molecule, referring to ingredients (often antioxidants, chelators, or film-forming agents) intended to reduce skin damage from particulate matter, ozone, and other airborne pollutants. Efficacy varies widely and depends on the specific actives used in a given formulation.
| Reported effect | How often | Notes |
|---|---|---|
| Mild irritation or stinging | Uncommon | More likely with antioxidant actives like vitamin C or niacinamide at higher concentrations. |
| Contact dermatitis | Rare | Typically due to fragrances, preservatives, or specific actives rather than the anti-pollution claim itself. |
| Allergic sensitization | Rare | Depends on individual ingredients; botanical extracts are a common trigger. |
| Comedogenicity / pore congestion | Rare | Possible with occlusive film-forming agents in some formulas. |
Frequencies reflect typical cosmetic use reported in the literature, not a guarantee for your skin.
