| Skin type | Rating | Why |
|---|---|---|
| Normal | Neutral | Surfactant |
| Dry | Neutral | Surfactant |
| Oily | Avoid | Highly comedogenic (5/5) |
| Combination | Avoid | Highly comedogenic (5/5) |

Is Laureth-4 comedogenic?
It has a comedogenic rating of 5 out of 5 in Pori's ingredient database, so people prone to breakouts may want to watch it. Ratings like this come from older tests on single ingredients, and a finished product with it isn't necessarily pore-clogging. A 2006 study in the Journal of the American Academy of Dermatology found that finished products made with comedogenic ingredients were not necessarily comedogenic, so treat the number as a hint, not a verdict.
How do I check a product with Laureth-4?
Scan the barcode or photograph the ingredient list with Pori's ingredient scanner (a Pro feature). It rates every ingredient for your skin type, flags fragrance, pore-clogging and irritating ingredients, and gives the product an overall match score. It's a guide to ingredients, not a diagnosis, so see a dermatologist about any reaction.
