In our reference data, Isostearyl Hydroxystearate can feed Malassezia (fungal acne).
Isostearyl Hydroxystearate is a branched-chain fatty acid ester used as an emollient and skin-conditioning agent that imparts smoothness and a non-greasy feel in creams, lotions, and color cosmetics. It functions primarily as a texture and spreadability enhancer rather than a biologically active treatment.
| Reported effect | How often | Notes |
|---|---|---|
Mild skin irritation | Rare | Occasional transient redness or stinging, generally in sensitive or compromised skin. |
Allergic contact dermatitis | Very rare | Isolated sensitization reports; esters of this type are considered low-allergenicity. |
Comedogenicity (pore clogging) | Uncommon | Possible in acne-prone individuals given its occlusive, oily nature. |
Frequencies reflect typical cosmetic use reported in the literature, not a guarantee for your skin.
