How can I find the best non-comedogenic sunscreen that is suitable for acne-prone skin?

Thanks for the question. It is difficult to recommend one sunscreen over another as the are no comparative studies showing that one sunblock is better than another and often there are individual variations in the preference of one sunscreen over another.

In general, I would recommend using sunscreens that have been specially formulated for acne prone skin from reputable brands and as you have done, purchase products that are labelled oil-free or non-comedogenic.

Often, the clogged pore themselves are not simply due to the product but the underlying skin tendency to develop comedones and clogged pores. This can be treated using creams that are comedolytic ie unclog the pores, like tretinoin cream or adapalene.

It is great that you are taking active steps to protect yourself from the sun with sunscreen. While no product is completely safe, we can try to minimize the risk of products clogging pores by using non-comedogenic products.

Many laboratories and scientists have been conducting research to evaluate which products are comedogenic/non-comedogenic. Some patients find this list useful for reference when choosing a product for their skin.

However, it must be said that it may not be possible to avoid all of the following ingredients as some of them are used as stabilizers for some products etc. Usually, if they are found in very low concentrations, it may still be acceptable to use them with no issues!
