HadaBuddy vs Yuka: Which Skincare Scanner Should You Actually Use?
Both apps scan barcodes and flag ingredients. But they solve different problems. Here's an honest comparison of what each one does well, what they miss, and which one fits how you actually use skincare.
Yuka is the app most people think of when they hear "scan skincare and see what's bad." It built a massive user base on a simple promise: point your phone at a product, get a score from 0 to 100. HadaBuddy does something different. Here's an honest comparison of where each one wins and where each one falls short.
The short answer
Use Yuka if you want a fast yes/no on whether a product is safe to buy, and you're comparison shopping at the drugstore.
Use HadaBuddy if you've already bought skincare and you want to know what routine to build from it, how the products work together, and what to fix when something isn't working.
They're solving different ends of the same problem. Yuka helps you buy better. HadaBuddy helps you use what you bought better.
What Yuka does well
Yuka's core loop is fast and satisfying. Scan a barcode, get a color-coded score (green, yellow, orange, red) with a brief explanation of any concerning ingredients. The UI is clean. The database is large. For someone standing in the Target aisle trying to decide between two cleansers, it's genuinely useful.
Strengths:
- Scale. Tens of millions of downloads, massive product coverage including food and cosmetics.
- Simplicity. One screen, one number, one decision.
- Brand independence. Yuka doesn't sell products, so its scores don't have an affiliate conflict.
- Social proof. Your friends have probably heard of it.
Where Yuka falls short
The same simplicity that makes Yuka great for quick decisions makes it bad for actually doing skincare.
1. It scores products, not routines.
A 95-rated moisturizer and a 95-rated retinol don't tell you anything about whether they work together on the same night. Yuka has no concept of routine. You could have a full routine of Yuka-approved products that gives you a reaction because two of them shouldn't be layered.
2. The scoring algorithm is simplified to the point of distortion.
Yuka flags ingredients based on broad risk categories (endocrine disruptor concerns, allergen lists, etc.) without weighing concentration, formulation context, or who's using it. A 1% retinol serum and a 0.1% retinol serum get the same flags. A product with a well-formulated preservative system and one without both get scored by the presence of phenoxyethanol, not by how much is in it.
The result is a lot of products flagged yellow or orange that are fine for most skin, and occasionally products flagged green that irritate sensitive skin because the algorithm doesn't know your skin.
3. It doesn't know your skin.
Yuka's score is the same whether you have dry, oily, sensitive, or acne-prone skin. There's no profile. There's no personalization. A product that scores 80 for everyone might be exactly what dry skin needs and exactly what oily skin should avoid.
4. It doesn't build routines.
After Yuka tells you a product is safe, you're on your own. When to use it, how often, what to pair it with, what order to apply. Yuka punts on all of this.
What HadaBuddy does that Yuka doesn't
1. Scans your whole shelf, not just one product at a time.
HadaBuddy lets you scan every product you own and keeps them in your shelf. Then it treats them as a system. What's redundant, what's missing, what shouldn't share a night.
2. Knows your skin type, concerns, and climate.
Set up your skin profile (oily, dry, combination, sensitive; your specific concerns; your age range; your location). Routine recommendations account for all of this. Oily skin in humid weather gets different suggestions than dry skin in winter cold, even for the same products.
3. Builds a 7-day routine from what you own.
HadaBuddy's AI looks at your whole shelf and produces a morning and evening routine for every day of the week. It rotates actives correctly (retinol on some nights, AHA on others, rest nights in between). It flags conflicts before you stack two products that shouldn't share a night. Yuka can't do this.
4. Treats ingredient combinations, not just individual ingredients.
Yuka scores one bottle. HadaBuddy understands that "retinol + AHA on the same night" is the problem, not either ingredient alone.
5. Routine sharing.
If a friend has good skin and you want to copy what they're doing, you can. HadaBuddy Pro users generate a shareable link to their routine. No equivalent in Yuka.
Where HadaBuddy is weaker than Yuka
Fair is fair. Here's where Yuka has the edge.
- Product database size. Yuka's database includes food, cosmetics, and more. HadaBuddy focuses only on skincare. If you want to scan your groceries, use Yuka.
- Universal brand recognition. Yuka has been around longer and has a bigger following.
- Simpler UX for first-time users. Yuka is very much a "one screen, one score, done" experience. HadaBuddy asks you to build a skin profile and scan multiple products before it produces anything useful. More setup.
- Free forever. Yuka has a free tier with most features. HadaBuddy has a free tier too (unlimited scans, personalized 7-day routines, ingredient analysis) but the AI Skin Advisor and routine sharing are Pro features.
Which should you use?
Use Yuka if:
- You're at the store deciding between two products
- You want quick ingredient flags without building a full routine
- You scan food and personal care products too, not just skincare
- You don't want to spend time setting up a profile
Use HadaBuddy if:
- You already have a shelf full of skincare and don't know how to use it
- Your routine stopped working and you need to figure out why
- You want a routine that actually accounts for your skin type
- You want to know which products work together instead of just which ones are "safe"
- You want skincare to feel less like homework
Use both if:
- Use Yuka at the store, HadaBuddy at home. That's the honest answer for someone who wants full coverage.

Where Yuka is headed vs where HadaBuddy is
Yuka has been iterating for nearly a decade and its core product is stable. It does the one thing very well. New features have been minor polish.
HadaBuddy is newer and moving fast. The differentiator is AI-built routines from your actual shelf, which is a category Yuka hasn't attempted. If you're someone who owns skincare you're not using effectively, that's the gap HadaBuddy is built for.
Try HadaBuddy for yourself
If you've been using Yuka and the "safe to buy" filter doesn't help you actually use what you have, HadaBuddy is the complement. Scan your existing shelf, set your skin profile, and see if the AI-built routine works better than the one you've been winging.

FAQ
Do HadaBuddy and Yuka use the same databases?
No. Yuka maintains its own proprietary database. HadaBuddy built its own by aggregating ingredient data from dermatology sources, regulatory databases (FDA, EU CosIng, MFDS Korea), and beauty retailers. Overlap on popular products, but different underlying sources.
Does HadaBuddy have a product rating like Yuka's score?
HadaBuddy shows ingredient breakdowns and flags concerns, but we don't reduce a product to a single 0-to-100 number. Too much gets lost in that compression. Two products with identical scores can behave differently for different skin types.
Can I use HadaBuddy without setting up a skin profile?
Yes, as a guest. You'll see ingredient info on scanned products. But routine generation (the core value) requires a profile. It takes about two minutes.
Is HadaBuddy better for K-beauty?
Yes, significantly. HadaBuddy's database leans heavily into K-beauty by design, with strong coverage of COSRX, Beauty of Joseon, Anua, SKIN1004, Laneige, Innisfree, Missha, and Torriden. Yuka has limited K-beauty coverage.
Is HadaBuddy available on Android?
Currently iOS only. Android is on the roadmap.
