Ingredient Guides: What Is in Chelure and Why
Each guide explains one ingredient we use: what it is, what published research says, why it is in our formulas, and which Chelure product contains it. We cite studies and say plainly where the evidence is limited. We are not doctors, and these pages are not medical advice.

How we choose and check our sources
We start from published research indexed on PubMed, preferring systematic reviews and randomized trials. Each guide ends with a numbered list of sources you can open. Where research is small, short, funded by a product maker or done at a different strength than our products, we say so. Where we could not find good research, we make no research claim. Our editorial policy explains how guides are written and updated, and our price comparisons use generic descriptions, not brand names, with the date they were checked.
Safety basics that apply to every ingredient
- Patch-test any new product on the jaw or inner forearm for a few days before using it on your whole face.
- Introduce one new active at a time, and give it a few weeks before judging.
- Use a broad-spectrum sunscreen every morning, especially with retinol, AHAs and brightening ingredients.
- If you are pregnant, breastfeeding or trying to conceive, ask your doctor before using retinol, salicylic acid or AHAs.
- See a doctor for patches that are sudden, uneven or spreading, for painful or scarring acne, and for rashes that do not settle.
