Does Tetrahexyldecyl Ascorbate clog pores?

Quick answer: Rarely — Tetrahexyldecyl Ascorbate has only a mild pore-clogging risk (rated 2/5) and suits most skin types, though very acne-prone skin may want to patch test. It is not a common fungal-acne trigger.

2/5
A mild, low pore-clogging risk
Comedogenicity scale: 0 = won't clog pores, 5 = very likely to clog pores.

Tetrahexyldecyl Ascorbate carries only a mild pore-clogging risk. It is fine for most skin types; very reactive or acne-prone skin may still want to patch test a new product that contains it.

Is Tetrahexyldecyl Ascorbate comedogenic?

Tetrahexyldecyl Ascorbate has a comedogenicity rating of 2/5 — a mild, low pore-clogging risk. Remember that where an ingredient sits in the list matters: Tetrahexyldecyl Ascorbate near the top means a higher concentration and more impact than the same ingredient near the end.

Acne-safe alternatives to Tetrahexyldecyl Ascorbate

If Tetrahexyldecyl Ascorbate breaks you out, these lower-rated active options are far less likely to clog pores:

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 Tetrahexyldecyl Ascorbate's 2/5 as a risk signal — most useful when the ingredient sits near the top of the list — rather than a verdict on one specific product.
