Pore Clogging Ingredient Checker | Detect Acne Triggers in Skincare & Makeup

Paste your skincare, makeup, or hair product ingredient list to instantly identify pore-clogging and comedogenic ingredients rated on the standard 0 to 5 dermatological scale.

Understanding the 0 to 5 Comedogenic Scale

Our checker evaluates cosmetic formulas using the clinical comedogenicity ratings originally developed by Dr. Albert Kligman and Dr. James Fulton:

  • Rating 0 (Non-Comedogenic): Will not clog pores (e.g., Squalane, Hyaluronic Acid, Glycerin, Niacinamide).
  • Rating 1 (Very Low Risk): Slight chance of clogging, safe for almost all acne-prone individuals.
  • Rating 2 (Moderately Low): Low pore-clogging risk; well tolerated by most normal and dry skin types.
  • Rating 3 (Moderate Risk): Common trigger for closed comedones and whiteheads (e.g., Avocado Oil, Sesame Oil).
  • Rating 4 (High Risk): Fairly high probability of clogging pores (e.g., Coconut Oil, Cocoa Butter, Isopropyl Palmitate).
  • Rating 5 (Severe Risk): Severe pore clogger; strong trigger for cystic and inflammatory acne (e.g., Wheat Germ Oil, Isopropyl Myristate, Algae Extract).

Frequently Asked Questions

How do I check if my moisturizer has pore-clogging ingredients?
Copy the full INCI ingredients list printed on your product packaging or retailer website, paste it into our checker box above, and click "Check Ingredients" to see a color-coded safety breakdown.
Does "non-comedogenic" on the label guarantee no acne?
No. In the United States and EU, "non-comedogenic" is not an FDA-regulated term. Many commercial products labeled non-comedogenic still contain ingredients rated 3, 4, or 5 on the clinical scale.
