### How do you calculate cosmetic formulation?

To do this, you firstly need to decide how much product you want to make – the total size of your batch.

### How do you read skincare ingredients?

The order the ingredients are listed on the label is important. Ingredients are listed in descending order from greatest amount to least amount present in the product (except ingredients present at a concentration of less than 1%; those can be listed in any order).

### How do you know if a recipe is less than 1%?

Any ingredient used in concentration of 1% or less can be listed in any order. In other words, the label starts listing ingredients in descending order but once it hits the 1% mark, it just adds ingredients at random. If they’re all present at (roughly) the same amount, the concentration criteria becomes useless.
