Best Skincare Ingredient Checker Apps in 2026: Pori, SkinSort, INCIDecoder, Yuka and More

The best skincare ingredient checker app depends on what you need. Pori rates each ingredient for your skin type and tracks your skin over time. SkinSort is the strongest all-rounder for matching products to your skin and routine. INKEEDecoder, the site formerly called INCIDecoder, explains ingredient lists line by line for free. Yuka, Think Dirty and OnSkin score products against large databases.

We make Pori, so we've put it first; here's what each app does well. We checked each app's own website and US App Store or Google Play listing in October 2026 for what it does, how it rates ingredients, which platforms it runs on and what it costs. Prices change often, so check the listing before you subscribe.

Which skincare ingredient checker apps are worth comparing?

Here are the six tools we compared, side by side, with prices as of October 2026 from the pages linked in each section below.

CosDNA, a long-running ingredient analysis site, blocked our automated checks in October 2026, so we couldn't verify its current features and left it out.

How do ingredient checker apps rate ingredients?

They use one of three methods, and each has a blind spot.

• Explanation only. INKEEDecoder describes what each ingredient does and adds simple ratings. You get context, and you do the judging.
• Hazard scoring. Yuka and Think Dirty flag ingredients linked to potential health concerns and roll them into a product score. The weak spot is dose. Yuka's own terms say the app does not evaluate effectiveness nor take into account the quantity of ingredients, and its sources page says it applies the precautionary principle and alerts consumers even when a risk is still under suspicion, including for ingredients used at levels that comply with current standards. A low score tells you a flagged ingredient is present; it doesn't tell you the product is unsafe at the amount used.
• Skin matching. Pori, SkinSort and OnSkin compare ingredients with your skin profile. That's more personal, but only as good as the profile: if you've got your skin type wrong, the ratings will be off too. Our guide on how to find your skin type helps here.

Two other caveats apply to every tool. "Clean" has no standard, scientific basis or regulatory oversight, and in one study of 1,470 products sold as clean, 82.9% contained fragrances or botanicals, common allergens. Comedogenic ratings also have limits: researchers found that finished products using comedogenic ingredients are not necessarily comedogenic, because those ratings came largely from animal tests of raw ingredients.

The best skincare ingredient checker apps, ranked

1. Pori: ratings for your skin type, plus skin tracking

What it does: Pori is a skin analysis app with an ingredient scanner built in. You scan a product's barcode or photograph its ingredient label, and each ingredient is flagged beneficial, use with caution or avoid for your skin type. The same app takes a selfie and gives you a 0 to 100 skin score with hydration, pores and texture, pigmentation and tone, and anti-aging breakdowns, a morning and evening routine, a skin diary, before-and-after comparison and progress charts.

How it rates: fixed rules over a curated list of about 250 common INCI ingredients. The AI only reads hard-to-read labels and writes a short summary of a verdict already computed; it does not set the score, so the same product gets the same rating every time.

Where others are stronger: about 250 ingredients is far fewer than OnSkin's 15,000+ or a full ingredient dictionary like INKEEDecoder. Barcode lookup uses Pori's own catalogue plus Open Beauty Facts data, so coverage of US products is thinner than Yuka's or OnSkin's 2 million products; photographing the label works when a barcode isn't found. Pori is iPhone-only, the scanner needs Pro, and the app is new, with too few App Store ratings to show an average.

Price as of October 2026: free download and free first skin scan; Pro is $9.99 a week with a 3-day trial, or $49.99 a year, per the App Store listing.

2. SkinSort: the best all-rounder for products and routines

What it does: SkinSort lets you photograph a product to see whether its ingredients suit your skin, with each ingredient explained. It also tracks your routine, warns about products that shouldn't be used together, filters products by ingredients you want to avoid, compares products side by side, finds cheaper dupes and has user reviews and a community. It rates 4.7 from about 6,400 App Store ratings.

How it rates: Match Scores that explain the reasoning behind each score, plus your own loved and avoided ingredients. Its Google Play listing says the company is proudly independent and doesn't allow brands to influence the information it shows.

Where it's stronger than Pori: product discovery (filters, side-by-side comparison, reviews and dupes), routine tracking with conflict warnings, a community, an Android app and a web version.

Watch out for: full access needs Premium, and the App Store lists many price tiers, so check the price at checkout.

Price as of October 2026: free download; in-app purchases listed from $7.99 a month, with annual plans from $19.99 to $59.99, per the App Store listing.

3. INKEEDecoder (formerly INCIDecoder): the best free ingredient explainer

What it does: INKEEDecoder breaks a product's ingredient list down line by line: what each ingredient does, plus irritancy and comedogenicity columns and a quick rating such as "goodie" or "superstar". Ingredient pages include official CosIng information, and the Decode INCI tool analyzes a list you paste or a photo you upload. It was started in 2015 by a computer scientist turned cosmetic formulator.

Why the new name: the Personal Care Products Council, which runs the INCI naming system, filed a trademark lawsuit over the use of "INCI". The dispute was resolved and the site renamed itself; it says the database and mission are unchanged.

Where it's stronger than Pori: much deeper explanations of each ingredient, a tool that decodes any pasted list, and it's free.

Watch out for: we found no app on its site, and its product pages don't tailor ratings to your skin type.

Price as of October 2026: free to browse; its site showed no paid plan when we checked.

4. Yuka: the biggest database for a quick hazard check

What it does: Yuka scans the barcodes of food and personal care products. It covers about 2 million cosmetic products, rates 4.8 from about 102,000 App Store ratings and is an Editors' Choice. For a product with a poor grade, it suggests an alternative.

How it rates: each ingredient gets one of four risk levels. The worst ingredient sets the ceiling: a high-risk ingredient means a score lower than 25/100, and a moderate-risk one caps it below 50. Its sources include the EU's SCCS, ECHA and IARC alongside databases such as Skin Deep, per its sources page.

Where it's stronger than Pori: a much larger product database, food scanning, Android and iPad apps, and a clear independence policy: Yuka says no brand can influence its scores and it does not advertise; it's funded through Premium.

Watch out for: the method doesn't account for how much of an ingredient is in the product, and its listings don't mention matching products to your skin type.

Price as of October 2026: free; Premium Member tiers listed at $10, $15 and $20 on the App Store. Premium adds a search bar, offline mode and food preference alerts.

5. Think Dirty: a chemical-focused shopping guide

What it does: Think Dirty scans barcodes and rates beauty and personal care products. It rates 4.8 from about 57,000 App Store ratings, and its Google Play listing says its database has over 850,000 products from Canada and the US. Extras include a bathroom shelf rating, an expiry date tracker and shopping lists.

How it rates: a Dirty Meter rating. The developer says it evaluates products based solely on their chemical content, not brand reputation or marketing claims, and doesn't weigh environmental or social factors. Its store listings don't explain how the score is calculated.

Where it's stronger than Pori: a larger North American product database, Android support and personalized allergen alerts (Premium).

Watch out for: it's a hazard-style rating, so the same dose caveat applies. It also links to retailers to buy cleaner-rated products.

Price as of October 2026: free download; Premium and All Access plans listed from $2.99 to $48.99, and a $199 lifetime option, on the App Store.

6. OnSkin: simple verdicts with a skin profile

What it does: OnSkin, from AIBY, checks products by photo, barcode or name against a database of 2 million products and 15,000+ ingredients. Skin Match compares products with your skin type, sensitivities, concerns and goals, and it builds morning and evening routines and scores hair products too. It rates 4.7 from about 33,000 App Store ratings.

How it rates: four product verdicts (Excellent, Good, Not Great, Bad) with a plain-language note per ingredient and suggested alternatives. The listing says scoring criteria are reviewed by in-house dermatologists.

Where it's stronger than Pori: a much bigger database, hair products and an Android app.

Watch out for: it needs iOS 18 or later, and several plans are weekly.

Price as of October 2026: free download; subscriptions listed from $4.99 to $39.99 on the App Store.

Which ingredient checker should you choose?

• You want ratings for your skin type and to see whether your routine works: Pori, which links the scanner to skin scans, a diary and progress charts. If you mainly want skin scores, see our AI skin analysis app comparison.
• You want product discovery with reviews, dupes and routine tracking: SkinSort.
• You want to understand ingredients for free: INKEEDecoder.
• You want one scanner for food and cosmetics: Yuka.
• You're on Android: SkinSort, Yuka, Think Dirty or OnSkin.
• You have reactive skin or eczema: any of these can flag fragrance, but your own history matters more. Our sensitive skin routine explains how to test products.

What can't an ingredient checker tell you?

None of these apps knows the exact percentage of each ingredient, because labels don't list it, and none can tell whether you personally are allergic to something. A product can score well and still irritate your skin, or score poorly and suit you fine. Treat any rating as a starting point, patch-test new products, and see a dermatologist if reactions keep happening. Pori, like the others here, is not a medical device and doesn't diagnose skin conditions.

Methodology and disclosure

This comparison is published by the team behind Pori, and we ranked Pori first. Features, ratings and prices come from each app's US App Store listing, Google Play listing or official website, as linked, checked in October 2026. App Store prices are in-app purchase ranges and can vary by region and over time. We didn't test the accuracy of any app's ratings, and nothing here is medical advice.
