How to Use the Pore Clogging Checker Tool: A Complete Guide
Master the pore clogging checker tool with our step-by-step guide. Learn how to analyze skincare ingredients, understand comedogenic ratings, and make informed decisions for clearer skin.

If you want to avoid skincare products that clog your pores, the Pore Clogging Checker is a free online tool that analyzes any skincare product for comedogenic ingredients in seconds. This step-by-step guide walks you through exactly how to use it.
What Is a Pore Clogging Checker?
A pore clogging checker scans the ingredient list of your skincare products and identifies ingredients that are known to be comedogenic, meaning they can clog your pores and cause breakouts. This is especially important for anyone with acne-prone skin.
The checker works entirely in your browser: nothing you paste is uploaded to a server, and there is no account or sign-up.
How to Use the Pore Clogging Checker (Step by Step)
Step 1: Find Your Product's Ingredient List
Locate the ingredient list on your product packaging. It is usually printed on the back or bottom of the container, often introduced by the word "ingredients". You can also find it on the product's web page.
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, or
- separated by commas
The tool counts how many ingredients it detected as you type and saves your draft locally, so an accidental refresh won't lose your work.
Step 3: Analyze the Results
Click Analyze list. Within a second you'll see:
- a color-coded verdict banner (clean, low-risk, or pore-clogging ingredients found)
- the comedogenic rating for every matched ingredient, on a 0-5 scale
- fuzzy matches with a "closest match" note, so typos on labels don't hide problems
Understanding the Results
The Comedogenic Rating Scale
- 0-1: unlikely to clog pores (safe for most skin types)
- 2: low risk (use with caution if you are very breakout-prone)
- 3: moderate risk (worth avoiding in leave-on products)
- 4-5: likely to clog pores (avoid on acne-prone skin)
Ingredients whose published ratings disagree are shown as a range, for example 3-4, and colored by the average.
See it live: paste any label into the pore clogging checker and every match lands on this scale in about a second.
What to Look For
- ingredients with ratings of 3 or higher, sorted to the top
- where they appear in the list: position approximates concentration
- the "not in the database" list, which is unknown rather than safe
4 Pro Tips for Using the Checker
- Check before you buy: analyze new products before purchasing to avoid wasting money.
- Start with leave-on products: moisturizer, sunscreen and foundation matter far more than rinse-off cleansers.
- Cross-reference: compare two products side by side to find the cleaner formula.
- Check your current shelf: the culprit behind persistent breakouts is often a product you already own.
Why You Should Use a Pore Clogging Checker
- Prevent breakouts before they happen
- Stop wasting money on products that work against your skin
- Understand exactly what is in your skincare
- Make informed purchasing decisions based on the full formula
Important Considerations
- Everyone's skin reacts differently. A low-rated ingredient may still cause issues for you personally.
- Ratings describe individual ingredients, not finished formulas. Concentration and formulation change the outcome.
- Always patch test new products before applying them to your entire face.
- Consult a dermatologist for advice tailored to your skin type.
Conclusion
The Pore Clogging Checker is an essential tool for anyone serious about skincare, especially those with acne-prone skin. By following this guide and using the tool regularly, you can make smarter decisions about the products you put on your skin.
