Direct exposure to the hyaluronic acid serum trend comes from owning top skincare companies with strong HA lineups, such as Estée Lauder Companies (EL) or L'Oréal (LRLCY), which stand to benefit from rising demand for premium serums. Indirect exposure can come from healthcare-aesthetics players; AbbVie (ABBV) owns Allergan Aesthetics, whose Juvederm and other HA-based products link the trend to the larger aesthetics market. Entrepreneurially, you could launch a private-label hyaluronic acid serum and build a DTC brand on Shopify or Amazon, leveraging contract manufacturers to scale quickly.
