Ingredient decoder
Paste the ingredient list from any product. We'll flag anything that may feed the yeast behind seb derm, and tell you why.
Have the product in your hand? On iPhone, open the Camera, point it at the ingredients, tap the text icon and copy. On Android, use Google Lens and tap Copy text. Then paste here. Nothing you paste is stored.
How we rate ingredients
Malassezia, the yeast linked to seborrheic dermatitis, feeds on certain fats. Each rating comes from lab studies that grew the yeast on cosmetic ingredients, or from the ingredient's chemistry when it hasn't been tested. "May feed" means it supported yeast growth in the lab, or is the same kind of ingredient as ones that did. It doesn't mean a product will cause a flare. Anything we haven't researched shows as "Not in our list", never as fine.
This is general information, not a diagnosis. Skin varies, so patch test new products, and see a dermatologist if a rash spreads, hurts or doesn't settle.
Looking for a leave-on with nothing flagged? Octaskin Serum is 2% salicylic acid in caprylic/capric triglyceride and octyldodecanol, two ingredients that didn't feed the yeast in lab tests.
