The present invention provides a nanomicell for a skin, and the nanomicell includes an oil substance, an extract of a Angelica Radix, an extract of a Lithospermum Radix, and a phospholipid layer. The extract of a Angelica Radix is formed by extracting the Angelica Radix with the oil substance, and the extract of a Lithospermum Radix is formed by extracting the Lithospermum Radix with the oil substance. The extract of the Angelica Radix and the extract of the Lithospermum Radix are packaged within the phospholipid layer to form a plurality of micells having a diameter of nano-level.本發明將傳統紫雲油膏以橄欖油和礦物油取代傳統麻油，並運用現代奈米微包技術將油溶性藥物外包以微薄的水層，製成粒徑小於100奈米的水溶性狀態，藉著奈米粒徑藥物的吸收滲透快速、不油膩的特性來改良傳統紫雲膏之缺點並增加紫雲膏的抗菌及組織癒合能力。
