What is Zinc Stearate?

Zinc Stearate is a functional ingredient (e.g. preservative, pH adjuster, texture). You'll most often see it in almost any formula, as a preservative, pH adjuster or texture agent.

Fungal-acne (Malassezia) safe? No — this is a common Malassezia (fungal acne) trigger, so avoid it if you have fungal acne. Check a whole product for fungal-acne triggers →

Is Zinc Stearate comedogenic?

Zinc Stearate has a comedogenicity rating of 0/5 — non-comedogenic (acne safe). Remember that where an ingredient sits in the list matters: Zinc Stearate near the top means a higher concentration and more impact than the same ingredient near the end.

How we rate comedogenicity — and its limits

The 0–5 comedogenicity scale comes from dermatology research that measured how much individual ingredients clogged pores, originally using the rabbit-ear assay (Fulton et al., 1984). A rating reflects an ingredient's potential to clog pores at high concentration — not a guarantee that any finished product will break you out.

That distinction matters. A later review (Draelos & DiNardo, 2006) found that a single ingredient's comedogenic score does not reliably predict how a complete formula behaves on real skin: concentration, the rest of the formula, and your own skin all change the result. So read Zinc Stearate's 0/5 as a risk signal — most useful when the ingredient sits near the top of the list — rather than a verdict on one specific product.
