隨著近幾十年來奈米技術的出現與應用的興起，它在化妝品領域中也掀起了不小的浪潮。許多奈米技術在防曬、美白和抗皺等相關方面都已經有所應用。鑒於奈米技術在經皮吸收、皮膚儲留、提升功效以及降低皮膚刺激性等方面的優勢，其在化妝品領域仍有很大的發展空間。本文從奈米粉體、脂質膠體分散系統、奈米乳液、奈米微粒等不同製備技術和劑型的角度，綜述了近年來奈米製劑在化妝品領域的研究進展，以期為奈米技術在化妝品中的應用與硏究提供一定的借鑒。

With the emerging and rising application of nanotechnology, it is making waves in the field of cosmetics. Many nanotechnologies have been applied in sun protection, whitening and wrinkle resistance. In view of the advantages of nanotechnology in the aspect of trans-dermal, skin retention, enhanced efficacy and reduced skin irritation, it still has a huge development space in cosmetics. Here, the research and application of nanotechnology were reviewed in recently years from the point of the dosage form and preparation such as Nanopowder, Lipid colloidal dispersion system, Nano-emulsions and Nanoparticles.
