<p>A promotor for biological hyaluronic acid synthesis and a composition for external application to the skin comprise, as an effective component, an extract of the seaweed Ulva pertusa. The promotor exhibits a substantially excellent biological hyaluronic acid synthesis-promoting effect and accordingly activates the skin cells, prevents the aging thereof and the formation of wrinkles and makes the skin smooth and fresh. Thus, it can provide a highly safe agent externally applied to the skin. Consequently, the composition can widely be used in a variety of preparations such as various cosmetic creams, milky lotions, toilet waters, beauty essences, packs, under-makeups, foundations, jellies and ointments.</p> |
