What Does Comedogenic Mean? (And Why It Matters for Your Skin)

🧴 What Does “Comedogenic” Actually Mean?

The word “comedogenic” comes from the word comedo — the technical term for a clogged pore.

• Open comedo = blackhead
• Closed comedo = whitehead

So when an ingredient is comedogenic, it means it can block your pores and lead to breakouts.

‍

The Comedogenic Scale (0–5)

Each skincare ingredient is rated based on how likely it is to clog your pores. Here's a simple breakdown:

0 – Non-comedogenic‍

This means the ingredient is highly unlikely to clog pores. Examples: Glycerin, Squalane

1 to 2 – Low risk

‍Slight potential to cause congestion, but generally safe for most skin types.

3 to 5 – Moderate to High Risk

‍These are the pore-cloggers to watch out for — especially if you’re acne-prone. Examples include Coconut Oil (4), Isopropyl Myristate (5), and Wheat Germ Oil (5).

💡 Tip: The higher the number, the more cautious you should be — especially if the ingredient appears in the top half of a product label.

‍

Why It’s Confusing

Here’s the catch: the label “non-comedogenic” isn’t regulated. A product can say it’s safe for acne-prone skin, but still contain pore-clogging ingredients.

And many pore-cloggers have names that sound totally harmless, like:

• Ethylhexyl Palmitate
• Cetearyl Alcohol
• Algae Extract
• Wheat Germ Oil

Unless you’re trained in cosmetic chemistry, spotting them is tough.

‍

Do Comedogenic Ingredients Affect Everyone?

Not always. Some people can use coconut oil or beeswax with zero breakouts. But if you're:

• Prone to acne
• Dealing with congestion or texture
• Seeing “mystery breakouts” after switching products...

…then you might be sensitive to comedogenic ingredients — and checking your labels is a must.

🛠️ How to Know if a Product Is Comedogenic

You have two options:

1. Memorize every high-risk ingredient (good luck!!)
2. Use a comedogenicity checker tool like ChekIt

ChekIt lets you paste a full product ingredient list and instantly flags:

• Pore-clogging ingredients
• Comedogenicity ratings
• Irritants or known acne triggers

💡 It’s like having a skincare formulator in your back pocket.

‍

What to Do if a Product Has Comedogenic Ingredients

If a product has comedogenic ingredients:

• Don’t panic — test it carefully if you're not acne-prone
• Avoid layering multiple comedogenic products (they compound)
• Swap for a cleaner alternative (your esthetician can help)
• Use tools like ChekIt to audit your entire routine
