Why ingredients don't always match

How to Format Ingredients for the SkinSort Checker

Our Ingredient Checker helps you understand what each ingredient in your skincare product does.

To get the best results, it is important to use a properly formatted ingredient list.

Here is how to make sure your list works with the checker:

Best Format: Comma-Separated INCI Names

For the most accurate results, copy and paste the full official ingredient list; it can usually found on the product packaging or brand website. Each ingredient should be separated by a comma.

Example of a correctly formatted INCI ingredinet list:
Aqua, Glycerin, Ascorbic Acid, Niacinamide, Tocopherol

This is called the INCI format (International Nomenclature of Cosmetic Ingredients). It is the standard format used on product packaging and is usually required by law in several countries.

Common Names (Like “Vitamin C”) Often Work

Our Ingredient Matcher recognizes many common names like:

• “Vitamin C” (for Ascorbic Acid or its derivatives)
• "Green tea”
• "Shea butter"

That said, using the full INCI names like Aloe Barbadensis Leaf Extract or Camellia Sinensis Leaf Extract will always give you the most accurate match.

Unfortunately, brands sometimes come up with unique ingredient names that we haven't handled yet. If you come across something like this, feel free to let us know so we can improve our Ingredient Matcher.

Formats That May Not Work

Avoid these formats, as they can cause errors or prevent results from showing up:

• Ingredients listed with line breaks or random symbols
• Including extra descriptions or emojis
• Copying marketing blurbs instead of the actual ingredient list

Example of a format that might not work:
Water

Glycerin

Vitamin C (brightening)

Retinol (anti-aging)
