What Is a Pore Clogging Checker?
A pore clogging checker scans the ingredient list of your skincare products and identifies ingredients that may be comedogenic, meaning they could clog your pores and cause breakouts. This is especially important for anyone with acne-prone skin.
How to Use the Pore Clogging Checker (Step by Step)
Step 1: Find Your Product’s Ingredient List
Locate the ingredients list on your product packaging. It is usually printed on the back or bottom of the container. You can also find it on the product’s website.

Step 2: Enter the Ingredients
Copy and paste the complete ingredient list into the checker’s input box. You can enter ingredients in two ways:
- One ingredient per line
- Separated by commas

Step 3: Analyze the Results
Click the “Analyze Ingredients” button. The checker will:
- Identify comedogenic ingredients in your product
- Show the comedogenic rating for each ingredient (scale of 0-5)
- Highlight flagged ingredients with detailed information

Understanding the Results
Comedogenic Rating Scale
- 0-1: Unlikely to clog pores (safe for most skin types)
- 2-3: Moderately comedogenic (use with caution if acne-prone)
- 4-5: Likely to clog pores (avoid if you have acne-prone skin)
What to Look For
- Ingredients directly identified as comedogenic
- Similar ingredients that may also be comedogenic
- Safety notes and usage precautions for each flagged ingredient
