How can you tell if a product is non-comedogenic?

A product is classified as non-comedogenic primarily through explicit labeling that indicates it has been tested and proven not to clog pores. This designation is significant because non-comedogenic products are specifically formulated to avoid blocking hair follicles, which can lead to acne and other skin issues. The testing involved typically assesses the product's formulation against criteria for pore-clogging potential.

The other choices do not provide the same level of reliable indication. The color of a product, such as blue, has no bearing on its comedogenic properties. Price or the retail location, such as dermatology offices, also does not guarantee that a product is non-comedogenic; these factors are more reflective of branding or marketing rather than formulation science. Lastly, while the absence of alcohol or fragrance may suggest a gentler formulation, it does not directly correlate to non-comedogenic properties since many non-comedogenic products can still contain these ingredients without affecting their ability to keep pores clear.
