HOWARU BL-04® studies suggest it modulates the immune system, and clinical data supports the use of this strain for immune health1,2. This is particularly important for skin health as immune modulation is one potential mode of action in gut-skin communication.
An in vitro³ trial with human dermal fibroblasts showed potential benefits of HOWARU BL-04® on skin beauty by supporting collagen homeostasis and balancing immunological status during inflammatory stress. A new clinical study4 showed HOWARU BL-04® benefits on skin wrinkles at 4 weeks. A consumer study with HOWARU BL-04® showed perceived improvements in skin wrinkles, hydration and overall skin health at week 4 and 85.
