Chen Jung-hui first researched common cosmetics delivery systems, such as using liposomes (nanoscale fat bubbles). Because they are compatible with the outer keratinous layer of the epidermis, they are able to take nutrients into the skin. Next to liposomes in importance are multiple emulsions, in which oil and water molecules are combined but chemically separate.
陳榮輝首先研究化妝品常用的載體，如微脂粒（一種奈米級脂肪球），因為與皮膚角質層相容，能將養分帶進皮膚；其次如多重乳化物，是一種油中包水再包油的物質型態，能將化妝品的水、油性養分融合。
