01 · No diagnosis
Not a medical service
Comedogenic Checker does not diagnose acne, allergy, irritation, infection, or any other condition. It does not replace examination, diagnosis, or treatment by a licensed healthcare professional.
Do not stop or change prescribed treatment because of a checker result. If symptoms are painful, severe, persistent, rapidly worsening, or causing scarring, seek care from a board-certified dermatologist or another qualified clinician.
02 · Ingredient evidence
A source match is not a product outcome
Ratings on this site reproduce historical ingredient-level screening observations. A match does not establish the behavior of a finished product or the response of a particular person.
Exact concentration, purity, vehicle, complete formula, exposure pattern, skin condition, routine, climate, and individual susceptibility can all affect practical experience.
03 · Dataset coverage
Unknown does not mean low
The source set is finite. An ingredient that is absent, misspelled, newly named, or expressed through a different nomenclature may appear under “not found.” The site does not assign a favorable value to unknown entries.
04 · Product changes
Labels and formulas change
Brands may reformulate without updating every retailer page at the same time. Use the label on the product you actually have and check the brand’s current information. This site does not maintain a product-formula database.
05 · External material
Links are evidence paths, not endorsements
Links to research papers, official databases, and other resources are provided for traceability. Comedogenic Checker does not control their availability, accuracy, accessibility, or privacy practices.
