The Role of Cacao Powder in Enhancing Skin Moisture and Reducing Wrinkles: A 12-Week Clinical Trial and In Vitro Study.

Skin aging is driven by a combination of internal and external mechanisms, with ultraviolet (UV) radiation being a prominent external factor contributing to photoaging. Photoaging manifests through several signs, including decreased skin hydration, diminished elasticity, coarse wrinkles, and dyspigmentation. Cacao beans, known for their flavonoids and polyphenols, offer potential anti-aging benefits.

Lactate utilization in Lace1 knockout mice promotes browning of inguinal white adipose tissue.

Recent studies have focused on identifying novel genes involved in the browning process of inguinal white adipose tissue (iWAT). In this context, we propose that the mitochondrial ATPase gene lactation elevated 1 (Lace1) utilizes lactate to regulate the browning capacity of iWAT, specifically in response to challenge with CL-316,243 (CL), a beta3-adrenergic receptor (β3-AR) agonist. The mice were injected with CL over a span of 3 days and exposed to cold temperatures (4-6 °C) for 1 week.
