pH Compatibility Checker

pH Compatibility Checker with Product Lookup






Not sure if two skincare products work well together? This tool helps you check whether their pH levels are compatible — so you can avoid irritation or reduced effectiveness.

How to use:

Select or enter the pH values of the two products you want to layer. Click “Check Compatibility” to see if they’re a good match. The result will tell you whether it’s safe to use them together or better to separate them in your routine.

Tip: Products with very different pH levels may cause sensitivity or cancel each other out. Always patch test first!
