Hydrogenated Polyisobutene

Many products use hydrogenated polyisobutylene as part of the formula; tinted moisturizers, sunscreens, lip glosses, lip balm, night creams, eye creams, and foundations. Hydrogenated polyisobutylene is a popular ingredient in sunscreens because it maintains SPF even after exposure to water (such as waterproof sunscreens). The multiple properties of this ingredient make it popular with skincare product manufacturers.

One of the beneficial qualities of hydrogenated polyisobutylene is its ability to moisturize the skin, making it a popular ingredient in skin creams. However, its role in skincare is to strengthen the moisture barrier, not to provide a lot of moisture. For example, hyaluronic acid is generally more suitable for absorbing moisture to the skin and has a high value in skincare formulations. On the other hand, the advantage of hydrogenated polyisobutylene is that it can strengthen the skin's natural barrier to reduce water loss.
