Frequently asked questions
How does the compatibility checker work?
It compares two common skincare ingredients against a curated list of well-known combinations and tells you whether they generally work well together, need caution, or are better used at different times.
What if my combination is not listed?
No known common conflict does not guarantee a product will suit you. Introduce one new product at a time and patch test. The PoreIQ app can read the full ingredient lists of your actual products.
