Ingredient Label Checker
Paste the ingredient list from any skincare, makeup or hair product. You will see which ingredients are worth avoiding, which are worth limiting, and which popular worries you can safely ignore, each with the strength of the evidence and the official source. No AI, no sign-up.

What the checker looks for
I built this from the same thirty-second habit I use before buying any new skincare or makeup: read the back, not the front. The checker knows 17 ingredient groups, from added fragrance and formaldehyde releasers to PFAS, and it also knows the ones that get flagged online without good reason. Each result says how strong the evidence is, because "linked to" in one lab study is not the same as a proven harm.
- Fragrance / parfum
- Longer-chain parabens
- Methyl- and ethylparaben
- Formaldehyde releasers
- Phthalates
- PFAS ("forever chemicals")
- Triclosan / triclocarban
- Oxybenzone and similar chemical UV filters
- Methylisothiazolinone (MIT)
- BHA
- Talc
- PEGs and ethoxylated ingredients
- Sodium lauryl sulfate (SLS)
- p-Phenylenediamine (hair dye)
- Hydroquinone
- Synthetic color additives
- Mineral oil / petrolatum
In the US, cosmetics do not need FDA approval before they are sold (color additives aside), so the ingredient list is your best tool. This checker is a shortcut, not a verdict on your health or on a product's safety. If you want to read labels on your own, start with INCI names decoded, or plan what to change first with the Swap Priority Planner.
Questions
How do I check if a skincare product is non-toxic?
Read the ingredient list on the back, not the claims on the front. Paste it into the checker: it flags the ingredients with the clearest reasons to avoid them, like added fragrance, formaldehyde releasers and PFAS, and tells you which popular worries are low concern.
Does a flagged ingredient mean the product is dangerous?
No. Dose and how you use a product matter. A flag means there is a reasonable case to choose something else next time, especially for products that stay on your skin. Use up what you have, then swap.
Why are some ingredients marked low concern?
Because many online lists flag ingredients the evidence does not support worrying about, like refined mineral oil or methylparaben at normal levels. Fear makes people give up; it is better to spend your attention where it counts.
Does the checker use AI or save my list?
No. It matches your list against our own reviewed database, and every flag links to the official source behind it where one exists. Nothing you paste is stored on our side; the list only lives in your link.
