Comedogenic Rating 1 Ingredients

Ingredients classified under Rating 1 (Very Low Risk). These ingredients exhibit minimal or zero pore-clogging potential.

Matching Ingredients (49)

  • Rosehip Oil — Dry-feel oil rich in linoleic acid and trans-retinoic-acid precursors; absorbs quickly with minimal occlusivity, very low clogging risk.
  • Grapeseed Oil — Lightweight, ~70% linoleic acid; minimal occlusivity but slight residue can be an issue for the most acne-prone users.
  • Sea Buckthorn Oil — High in linoleic acid and antioxidant carotenoids; very low comedogenic risk although the deep orange color can stain skin if undiluted.
  • Marula Oil — Predominantly oleic acid but extremely lightweight with high oxidative stability, giving it only a marginal pore-clogging risk.
  • Camellia Oil — Light, oleic-rich oil that absorbs cleanly; minor risk for very sensitive acne-prone skin.
  • Castor Oil — Dominantly ricinoleic acid; humectant and surface-occlusive but small molecular size keeps comedogenicity low for most.
  • Black Currant Seed Oil — Source of GLA and stearidonic acid; light texture with low pore-clogging risk.
  • Mineral Oil — Cosmetic-grade mineral oil is highly refined and inert with very large molecular size that sits on the surface but does not penetrate follicles.
  • Petrolatum — Inert hydrocarbon mixture with molecules too large to enter pores; occlusive but not comedogenic in standard formulations.
  • Squalane — Saturated, biomimetic hydrocarbon nearly identical to skin's own squalene; absorbs cleanly with minimal pore-clogging potential.
  • Squalene — Unsaturated form; oxidizes more readily than squalane and oxidized squalene has been linked to comedone formation.
  • Kokum Butter — Hard, stable butter dominated by stearic acid; minimal comedogenic risk and useful as a structural emollient.
  • Illipe Butter — Hard butter chemically close to cocoa butter but lower in palmitic acid; limited clogging risk in most formulations.
  • Cupuacu Butter — Highly humectant butter with phytosterols; large molecular structure keeps it largely on the surface without clogging.
  • Sal Butter — Stearic-acid dominant hard butter; structural ingredient with low clogging potential.
  • Glyceryl Stearate — Standard non-self-emulsifying form is a mild emollient/co-emulsifier with minimal comedogenic risk.
  • Caprylic/Capric Triglyceride — Refined medium-chain triglycerides from coconut/palm; light, stable, and generally well tolerated by acne-prone skin.
  • Cetyl Esters — Wax-like ester blend that thickens lotions; low comedogenic rating and used as a vegan spermaceti substitute.
  • Coco-Caprylate/Caprate — Plant-derived silicone alternative with very low molecular weight; absorbs cleanly with negligible clogging.
  • Behenic Acid — Long-chain C22 saturated fatty acid; large molecular size keeps it on the surface with low pore-clogging potential.
  • Behenyl Alcohol — C22 fatty alcohol; large molecule keeps it on the skin surface with very low pore-clogging risk.
  • Dimethicone — Inert silicone polymer; molecules are too large to penetrate follicles, but heavy buildup over occlusive layers can theoretically trap debris.
  • Cyclomethicone — Volatile silicone that evaporates after application; leaves no occlusive residue and is essentially non-comedogenic.
  • Cyclopentasiloxane — Five-ring volatile silicone; flashes off the skin within minutes leaving dry feel without clogging.
  • Cyclohexasiloxane — Six-ring volatile silicone with slightly slower evaporation; minimal pore-clogging risk.
  • Dimethiconol — Hydroxyl-terminated silicone; provides slip and hair-like shine without entering follicles.
  • Phenyl Trimethicone — Glossy silicone used in foundations and serums; large molecular weight prevents follicular penetration.
  • Retinol — Vitamin A alcohol; oil-soluble but used in tiny percentages and increases cell turnover, often clearing rather than causing comedones.
  • Retinaldehyde — More potent retinoid intermediate; non-comedogenic with significant anti-acne activity.
  • Retinyl Palmitate — Retinol esterified with palmitic acid; mild retinoid with very low clogging risk despite the fatty acid carrier.
  • Tetrahexyldecyl Ascorbate — Oil-soluble ascorbic acid ester delivered in lipophilic vehicles; very low clogging risk despite oil base.
  • Sodium Laureth Sulfate — Ethoxylated sulfate; milder than SLS but still potentially irritating in high concentrations.
  • Sodium Cocoyl Isethionate — Mild syndet bar surfactant from coconut; very low irritation and non-comedogenic in rinse-off use.
  • Sodium Lauroyl Sarcosinate — Amino-acid based surfactant; mild and rinses cleanly without clogging.
  • PEG-100 Stearate — Ethoxylated emulsifier; water-dispersible and generally pore-safe.
  • Candelilla Wax — Plant-derived hard wax; structural ingredient with low pore-clogging risk.
  • Carnauba Wax — Hardest natural wax; used at low percentages and rarely associated with clogging.
  • Ozokerite — Mineral wax used as a structurant; large hydrocarbon molecules do not enter pores.
  • Microcrystalline Wax — Refined petroleum-derived wax; inert and not comedogenic.
  • Paraffin Wax — Highly refined hydrocarbon; low pore-clogging risk.
  • Tea Tree Oil — Volatile essential oil containing terpinen-4-ol; primarily antibacterial against C. acnes with negligible occlusivity.
  • Calendula Extract — Soothing botanical extract; non-comedogenic in water-based formulations, though oil infusions can be slightly heavier.
  • Propolis Extract — Resinous bee-derived extract; antibacterial with very low clogging potential.
  • Talc — Hydrated magnesium silicate powder; minor risk in heavy use through mechanical occlusion.
  • Hydrogenated Lecithin — Saturated, more stable form of lecithin; minimal comedogenic risk.
  • Dicaprylyl Carbonate — Dry-touch carbonate ester; light and non-comedogenic in standard use.
  • Hydrogenated Polyisobutene — Synthetic hydrocarbon emollient; large molecular weight prevents follicular penetration.
  • Isohexadecane — Branched hydrocarbon emollient; lightweight and pore-safe.
  • C12-15 Alkyl Benzoate — Light dry-touch ester; preferred over IPM/IPP and rated as having low clogging risk.
