The present invention relates to a silica aerogel composite comprising a hydrophilically surface-modified hydrophobic silica aerogel and an organic UV blocker supported in pores of the silica aerogel.The silica aerogel composite of the present invention causes no skin irritation since the organic UV blocker inducing skin irritation is stably supported inside the silica aerogel to minimize the contact with the skin. Also, the silica aerogel composite is high in the organic UV blocker content per unit weight, and exhibits an excellent blocking effect against both UVA and UVB compared with conventional UV blockers.
