EVALUATION OF IMPROVEMENTS IN SKIN SYMPTOMS WITH APPLICATION OF A LOTION CONTAINING GOLD LEAF

摘要

We investigated the effects of topical application of alotion containing gold leaf on skin symptoms in11 Japanese women between the ages of 20 and 59 (mean, 47.5 ± 4.6 years) with concerns about skin dryness and sagging. This was an open-label controlled study comparing the effects of alotion with (test article) and without gold leaf (control)，with application of each lotion on different sides of the face in the morning and at night for four consecutive weeks. The results showed that the test article significantly improved cutaneous water content, which reflected moisture retention in the skin, and cutaneous elasticity (return rate) ， suggesting that the gold leaf in the lotion improved moisture retention and elasticity of the skin. These effects were considered to be due to coating effects and the relaxing effects of gold leaf. We anticipate that the use of gold leaf-containing lotion will be a valuable approach in the cosmetology field.
