Which actives to separate
The conflicts that matter for home routines are the ones that leave skin raw or cancel a product: a retinoid plus a strong acid on the same night, or benzoyl peroxide layered on fresh L-ascorbic acid.
Niacinamide with acids is a popular myth of total incompatibility. Most people can use them. This checker flags the pairs with a practical reason to separate, and it says when a fear is ahead of the evidence.

Want a record of ingredient conflict checker, not a one-off?
Ingredient conflict checker settles the question above. The app is where that decision can be checked against six skin scores over the following weeks.
- Six saved scores: hydration, texture, tone, acne, pores, and redness
- A morning and evening routine built from the scan
- The same face, week after week, so a change shows up as a trend

The science
What the ingredient conflict checker checker decides, and what it leaves alone
- 01
A structured question, not a photo score
A checker fits when the answer depends on behavior, a label, or a number you already know. A camera cannot see how a product feels, what else is in the routine, or whether a breakout started after a new active.
- 02
How this page reaches a label
Work through the prompts in order. The result follows from the answers, in this browser, and the answers are not stored.
Tied answers stay tied. If two labels earn the same weight, both are shown, because forcing a single winner would invent confidence the answers did not have.
- 03
What the label means, and what the app records
Type ingredient names separated by commas.
The AISkincare app keeps a scan: hydration, texture, tone, acne, pores, and redness, then builds a morning and evening routine from those scores. This page answers once and does not store the photo.
Use the label to choose a next step, then check it against a scan if the question was about skin rather than about a product or a style.
- 04
Where this kind of check runs out
Ingredient charts are estimates from published lists, not a lab test of your bottle and not a medical clearance.
If the honest answer to a prompt is 'it depends' or 'I am in pain,' stop and treat that as the result. The page cannot examine you.
How to use a ingredient conflict checker result
Type ingredient names separated by commas. Include only leave-on actives, not the whole preservative system, if you are checking conflicts. Your skin's sting matters more than a chart.
Take the actions on the result card as a short list, not as a diagnosis.
How to answer so the label is worth having
Answer for the last two weeks, not for your best week or for a photo you wish you had taken. If a prompt is about a product, use the ingredient list on the bottle you own, not a similar product from another brand.
One pass is enough. Changing answers until the label feels flattering wastes the check.
A label today, a score over the month
Ingredient conflict checker can be retaken when the routine changes. It will not show whether redness or texture actually moved. That comparison is a scan in the same light, saved in the app.

What the ingredient conflict checker checker cannot decide
Ingredient charts are estimates from published lists, not a lab test of your bottle and not a medical clearance.
It cannot see beneath the skin, predict a reaction to an ingredient you have never used, or replace a clinician for a spreading rash, a changing mark, or painful acne.
How to use the result
- Type ingredient names separated by commas.
- Include only leave-on actives, not the whole preservative system, if you are checking conflicts.
- Your skin's sting matters more than a chart.
Where to go from here
If one part of the result stood out, open the tool that asks only that question. Each one states its limit in the same place, and each one links back to a guide when a longer explanation helps.
- Ingredient list decoderPaste a product's ingredient list and get a plain-language note on the actives and additives this guide recognizes. Unknown names stay unknown on purpose.
- Malassezia ingredient checkPaste an ingredient list and see which entries are often avoided in malassezia-aware routines. This is not a test for fungal acne and not a treatment.
- Pregnancy ingredient checkFlag ingredient names that commonly appear on pregnancy caution lists so you can ask your clinician. This is not a clearance to use or avoid a product.
- Comedogenic rating checkLook up comedogenic ratings for ingredients you paste. The numbers come from older charts, not from a test of the finished product on your face.
