What it is
A synthetic silicone polymer blend that crosslinks into a soft, elastic network. It is commonly used in cosmetics to improve texture and wear.
How it works
When applied, the crosspolymer forms a thin, flexible film on the skin's surface. This film fills in uneven texture, reduces the appearance of pores, and provides a smooth base for makeup. It also helps other ingredients spread evenly and can improve water resistance.
Pros
Smooths texture instantly
Fills in uneven skin texture and fine lines on contact, giving a soft-focus effect that helps makeup apply more evenly.
Non-comedogenic for most
Despite being a film former, this silicone blend is generally considered non-comedogenic and safe for most skin types, including sensitive skin.
Cons and cautions
Can feel heavy on oily skin
For those with very oily or acne-prone skin, the film may feel occlusive or contribute to a greasy buildup over time.
Requires thorough removal
Because it forms a water-resistant film, it may not rinse off with gentle cleansers alone and often needs an oil-based cleanser or double cleansing.
Best for
- People who want a smooth, poreless-looking finish under makeup
- Those with normal to dry skin looking for a silky texture in moisturizers
Use caution if
- Individuals who prefer silicone-free routines or have very oily skin that feels congested by silicones
