Understand your sunscreen's ingredients—not guess its SPF.

How to check a label

1. Paste all ingredients from the sunscreen carton, bottle or authorised product listing.
2. Identify the filter names, such as Zinc Oxide in the sample, and other ingredients that affect texture and preservation.
3. Use the ingredient detail links to understand documented functions and any sourced regulatory flags.
4. For protection, rely on the product's tested SPF and broad-spectrum or UVA claims, not on an ingredient list or this checker.

Which names are UV filters?

Sunscreen labels contain UV filters and many non-filter ingredients. Zinc Oxide and Titanium Dioxide can be used as mineral UV filters. Octocrylene is another filter used in some products. Their regulatory use depends on country and formulation.

Can ingredients tell you the SPF or UVA protection?

No. The ingredient list cannot establish a finished product's SPF, UVA protection or water resistance. These are properties of a tested formulation. Do not use this checker as a substitute for the SPF or other protection statements on the pack.

A sourced restriction on one ingredient also cannot demonstrate that this product is unlawful or unsafe: the list does not disclose the full concentration and exposure information.

What about the rest of the sunscreen?

Glycerin, Dimethicone and preservatives can have non-filter roles in a sunscreen formula. Some help with texture or usability; they should not be counted as extra UV filters. Use compare ingredient lists to see differences between two products.
