Comedogenic Rating 5 Ingredients

Ingredients classified under Rating 5 (Severe Risk). These ingredients exhibit high pore-clogging potential.

Matching Ingredients (6)

  • Wheat Germ Oil — Extremely high in linoleic and palmitic acids combined with a thick, sticky consistency that resists absorption, consistently rated the most comedogenic plant oil on the Fulton scale.
  • Isopropyl Myristate — Synthetic ester of isopropanol and myristic acid; small molecular size penetrates the follicle quickly and is the textbook comedogenic trigger.
  • Isopropyl Isostearate — Branched-chain isopropyl ester rated highly comedogenic in rabbit-ear assays; rapidly enters follicles and resists clearance.
  • Myristyl Myristate — Wax ester combining two myristic-acid units; solidifies in pores and ranks among the highest comedogenic scores reported.
  • Myristic Acid — C14 saturated fatty acid with very high comedogenic score; forms hard wax plugs in pores when present in concentration.
  • Algae Extract — Highly variable concentrated marine extracts contain heavy lipids and iodine compounds that strongly correlate with comedone formation in studies.
