No, quite the opposite! Unlike synthetic oils or silicones, beef tallow is non-comedogenic. Since tallow is 97% bio-identical to your skin's own sebum, your skin recognizes it as "body-own" and processes it optimally.
In fact, beef tallow even regulates your natural sebum production. This means your skin stops overproducing oil out of desperation – a common reason for clogged pores and pimples. Many customers with acne report significantly clearer skin after 4-6 weeks.
