That is the promise of hydrogenated polyisobutene, and it is a promise kept in millions of products worldwide. Consumers crave hydration, but detest heaviness or shine, and this ingredient delivers the best of both worlds. Its rapid absorption and non-comedogenic profile make it a go-to for all skin types, including those prone to congestion or sensitivity. This versatility is a major reason why hydrogenated polyisobutene is now found in everything from daily face lotions to targeted treatment balms.

The Moisture Barrier and Locking in the Benefits

Hydrogenated polyisobutene’s real magic lies in its ability to create an invisible, protective layer on the skin. This barrier minimizes transepidermal water loss, which is essential for maintaining long-lasting hydration. Unlike heavier occlusives, it does not suffocate the skin or clog pores, making it ideal for modern skincare routines that emphasize both efficacy and comfort. The result is skin that feels supple and nourished, with a noticeable reduction in dryness and flakiness. For formulators, this means greater flexibility in creating products that work for a wide range of consumers, from oily to dry skin types.
