Optimization of the Composition of a Cosmetic Formulation Containing Tremella fuciformis Extract (Fungi)

According to recent trends, people are more interested in cosmetic products based on natural raw materials, known to be safe for humans, including extracts obtained from selected plants, rich in active ingredients, such as proteins, vitamins, micro- and macro-elements, phospholipids, antioxidants, and natural preservatives. An example of such raw materials is Tremella fuciformis extract, which is a natural alternative to hyaluronic acid. It retains water deep in the skin cells and stimulates the skin to fight free radicals, which are responsible for the premature aging of the skin. The aim of this study was to optimize the composition of cosmetic formulations based on natural substitutes for the synthetic substances, as well as their characterization, which included the determination of the physicochemical and skin care properties. Formulations containing Tremella fuciformis extract had the effect of reducing TEWL by 12.4%, compared to a formulation that did not contain this active ingredient, and allowed adequate hydration of the epidermis, which was confirmed by apparatus methods. Additionally, dermatological tests were also conducted for the formulations obtained, which showed that no erythema or swelling/irritation was observed in any of the test volunteers 48 and 72 h after the application of the product.

Automated summary

Based on recent trends, there is an increasing interest in cosmetic products made from natural raw materials that are considered safe for human use. These materials include plant extracts containing proteins, vitamins, minerals, phospholipids, antioxidants, and natural preservatives. One example is Tremella fuciformis extract, which acts as a natural alternative to hyaluronic acid. This extract retains water in the skin cells, stimulates the skin to combat free radicals, and prevents premature skin aging. The study aimed to optimize the composition of natural cosmetic formulations and characterize their physicochemical and skin care properties. Formulations containing Tremella fuciformis extract reduced transepidermal water loss (TEWL) by 12.4% compared to formulations without this active ingredient, and effectively hydrated the epidermis as confirmed by instrumental methods. Dermatological tests showed no erythema, swelling, or irritation in volunteers 48 and 72 hours after product application.
