One product, two skin profiles. AllerNote reads the label, then answers for you.
The difference Same product.
Same product.
Different answers.
A moisturizer rated "clean" by Yuka can still trigger your contact dermatitis, because it contains your allergen under a different INCI name.
AllerNote maps every allergen to all known chemical synonyms. "Fragrance" catches Parfum, Linalool, Limonene, Geraniol, Eugenol, and 20+ more variants. No other scanner does this.

Real reviews from patch-tested skin.
"I used to spend 20 minutes reading every label at the store. Now I just snap a photo and AllerNote tells me if it's safe. It caught Linalool in a 'fragrance-free' moisturizer I almost bought."
"After my patch test, my dermatologist gave me a list of 12 allergens to avoid. I put them all into AllerNote and now shopping is actually manageable. The Trigger Detective feature is brilliant."
"I didn't even know I was allergic to MI preservatives until I started tracking reactions here. The app connected the dots across three different products. Game changer."
Guide
Why personalised allergen checks matter for contact dermatitis
Contact allergic dermatitis is an immune reaction to specific substances that touch your skin, often fragrances, preservatives, metals, or rubber accelerators. Unlike simple irritation, a true contact allergy does not disappear because a product is marketed as natural, clean, or hypoallergenic; the reliable approach is to avoid your documented triggers and every INCI synonym they hide behind on labels.
Generic beauty scores cannot know that you tested positive for methylisothiazolinone, nickel, lanolin alcohol, or a composite fragrance mix. AllerNote stores the ingredients and codes from your patch test or dermatologist list, then cross-checks every label scan, catalog lookup, and AI answer against that profile so you see Safe, Warning, or Avoid based on your biology, not a popularity algorithm.
We combine clinician-used allergen references, INCI labelling standards, and synonym mapping so hidden names still surface when they matter to you, for example peanut oil listed as Arachis Hypogaea Oil. Start with the free scanner on this page, then create an account to save your allergens, explore the product catalog, and use Trigger Detective to connect flare-ups to overlapping ingredients.
