Ingredient list › Cyclohexasiloxane
Does Cyclohexasiloxane clog pores?
Quick answer: No — Cyclohexasiloxane is non-comedogenic (rated 0/5) and is not known to clog pores. It is not a common fungal-acne trigger.
Cyclohexasiloxane is considered non-comedogenic — it is not known to clog pores and is generally a safe choice for acne-prone skin.
What is Cyclohexasiloxane?
Cyclohexasiloxane is a silicone that gives a smooth, blurring finish. You'll most often see it in primers, foundations, serums and 'smoothing' or 'blurring' products.
Fungal-acne (Malassezia) safe? Yes — it is not on common Malassezia (fungal acne) trigger lists. Check a whole product for fungal-acne triggers →
Is Cyclohexasiloxane comedogenic?
Cyclohexasiloxane has a comedogenicity rating of 0/5 — non-comedogenic (acne safe). Remember that where an ingredient sits in the list matters: Cyclohexasiloxane near the top means a higher concentration and more impact than the same ingredient near the end.
Similar acne-safe ingredients
Cyclohexasiloxane is already a low-risk choice. Other acne-safe options you may see alongside it include:
- Dimethicone — Low risk · 1/5
- Dimethicone Crosspolymer — Low risk · 1/5
- Phenyl Trimethicone — Low risk · 1/5
- Cyclomethicone — Acne safe · 0/5
- Cyclopentasiloxane — Acne safe · 0/5
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 Cyclohexasiloxane'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.
AcneSafeCheck compiles published comedogenicity ratings and dermatology references into one searchable database. It is educational, not a lab test of your specific product, and not medical advice.
