Free Skincare Tools & Calculators
Use the Product Safety Checker to analyze product names and barcodes, check full ingredient lists, compare compatibility, and build routines with tools designed to answer practical skincare questions. This hub is best used when you want help turning ingredient knowledge into a plan you can actually follow.
These tools are educational. They can help you compare ingredients, routine order, and tolerance questions, but they do not replace patch testing or medical care for severe irritation, allergic reactions, or persistent skin disease.
Essential Skincare Ingredients Wheel
A visual guide to the most effective ingredients by category
How to Use This Guide:
Identify your primary skin concerns and select ingredients from the appropriate categories. For a well-rounded routine, include at least one ingredient from each of these essential categories.
Start with one ingredient from each category
Layer compatible ingredients for synergy
Rotate ingredients based on skin needs
Choose the tool by question
Use the ingredient analyzer for INCI lists, the compatibility checker for pairing questions, and the routine builder when you need a starting structure.
Use outputs as educational guidance
These tools work best as a starting point for patch testing, product research, and routine planning rather than a diagnosis or a guaranteed outcome.
Escalate when skin is struggling
If irritation is severe, acne is scarring, or a reaction is escalating, medical care matters more than another calculator result.

Ingredient Compatibility Checker
Use this first if you already know the ingredients you want to combine but are not sure whether they belong in the same routine. It is one of the fastest ways to catch common layering mistakes before they turn into irritation.
Try it nowPick the Right Tool for the Job
Use the compatibility checker when you already know the ingredients you want to combine. Use the routine builder when you need a starting structure. Use the analyzer when you want context on one ingredient before you buy a product.
The simplest path is usually the best one: solve one routine question at a time instead of bouncing between every tool in one session.
Need Help Choosing the Right Tool?
If you are not sure where to begin, start with the routine builder for structure, then move into the analyzer or compatibility checker once you have a specific ingredient question to solve.
