What Squalene does

  • Softens dry, rough-feeling skin
  • Gives a light, non-greasy glide
  • Helps skin hold onto moisture

Squalene is a natural oil. Early supplies came from shark liver. Most cosmetic squalene today comes from plants, such as olives and amaranth seed. Your own skin also makes squalene as part of its natural surface oils. The label may not name the source.

Formulators like squalene because it is light, spreads easily, and feels close to skin. It is an unsaturated oil, so it can break down when exposed to air over time. That is why many products use squalane, its more stable, hydrogenated form. In lip care, squalene helps a balm glide on and feel soft rather than waxy.

Good for

Suits people who want a light, skin-like oil that softens without a heavy or sticky feel.

Frequently asked questions

Is squalene the same as squalane?

Not quite. Squalene is the unsaturated oil. Squalane is its more stable form, made by adding hydrogen so it resists breaking down. Both feel light and help soften skin.

Is squalene good for sensitive skin?

It is generally well tolerated and rarely causes irritation for most people. Anyone with known sensitivities should still patch test a new product first. Check the full ingredient list for other ingredients that may bother you.
