Ingredient Info

Silica is a mineral powder derived from silicon dioxide that's commonly used in skincare and makeup products. It works primarily as a texture enhancer and absorbent, helping to mattify skin, improve product feel, and absorb excess oil.



Benefits

  • Mattifies skin and reduces shine
  • Improves product texture and spreadability
  • Absorbs excess sebum and moisture
  • Creates a smooth, refined appearance

Potential concerns

  • When used as nanoparticles, potential for skin penetration remains under study
  • Inhalation of silica powder (primarily occupational concern) has known health risks; topical use in cosmetics is considered lower risk
  • Listed among potential carcinogenic substances in cosmetic formulations, though safe use levels and regulatory limits are established in the EU and US

Science: A 2023 review of European facial cosmetics identified silica among potential carcinogenic ingredients present in commercial products, though this reflects presence rather than proven harm at typical use concentrations. Research on silica nanoparticles suggests they are being developed for cosmetic use, but percutaneous penetration and long-term safety data remain limited. Regulatory agencies (EU, FDA) have established safe concentration limits for cosmetic use.
