Ingredient Info

Hydrogenated polyisobutene is a lightweight oil derived from petroleum that works as an emollient (skin softener) and film-former in skincare products. It helps lock moisture into the skin and creates a smooth, non-greasy feel on application.



Benefits

  • Improves skin hydration by reducing water loss from the skin surface
  • Creates a smooth, pleasant skin texture with minimal greasiness
  • Long-lasting moisturizing effect compared to some alternative emollients
  • May provide subtle skin-tightening and smoothing effects when combined with certain polymers

Potential concerns

  • Petroleum-derived ingredient; may not appeal to consumers seeking natural products
  • Occlusive nature means it may feel heavy or cause buildup on very oily skin types

Science: Clinical studies demonstrate that hydrogenated polyisobutene effectively reduces transepidermal water loss (skin dehydration) by up to 33% and maintains this effect for several hours. When formulated with certain polymers, it contributes to measurable improvements in skin firmness and wrinkle appearance in aging skin.
