Halobacteria Formula Improvement of Skin Care-A Randomized, Double-Blind, Placebo-Controlled Clinical Study.

Abstract

Halobacteria trueperi, an extremophilic microorganism thriving in high-salt environments, produces extracellular polysaccharides with potential anti-inflammatory and anti-aging properties. However, its clinical efficacy in skin improvement remains unclear. This study focuses on H. trueperi TCI66207, isolated from the Pacific Ocean at a depth of 662 m near Hualien, and its potential to enhance skin parameters, aiming to develop a novel functional formulation for pharmaceutical and cosmetic use. This sudy aims to evaluate the clinical efficacy of H. trueperi TCI66207 on various skin parameters and its potential for developing new functional cosmetic formulations. A total of 40 subjects were recruited and randomly divided into two groups: the test group applied a serum containing H. trueperi TCI66207, while the placebo group used a basic serum. Subjects were instructed to apply the serum twice daily for 4 weeks. Skin parameters, including moisture, brightness, elasticity, pigmentation (spots and UV spots), texture, wrinkles, pores, and collagen density, were assessed before and after the 4-week application period. After 4 weeks of using the H. trueperi TCI66207 serum, significant improvements were observed in all measured skin parameters compared to baseline, with notable enhancements in moisture, brightness, elasticity, texture, and collagen density, along with reductions in wrinkles, spots, and pore size. Halobacteria trueperi TCI66207 serum demonstrates a clear ability to improve skin conditions and delay signs of aging, making it a promising candidate for the development of new cosmetic formulations with potent anti-aging and skin-rejuvenating properties.
