In our reference data, Polyglyceryl-2 Isostearate can feed Malassezia (fungal acne).

Skin irritation | Rare | Mild, transient irritation possible, especially on sensitive or compromised skin. |
Allergic contact dermatitis | Very rare | Sensitization to polyglyceryl esters is uncommon but has been occasionally reported. |
Comedogenicity / pore congestion | Rare | Generally considered low risk, but rich emollient esters may contribute in acne-prone individuals. |
Eye stinging | Rare | Possible transient stinging if formulation contacts the eyes. |
