Green tea (GT) is rich in Phyto-active compounds such as epigallocatechin gallate
(EGCG), epigallocatechin (EGC), epicatechin gallate (ECG), epicatechin (EC), catechin, and tannic
acid, which exhibit synergistic effects when combined. Preclinical studies demonstrate that GT and
its compounds can reduce reactive oxygen species (ROS), enhance antioxidant capacity, and alleviate
aging-related issues such as memory impairments, cognitive decline, and shortened lifespan.
Clinical trials corroborate the efficacy of topical GT formulations in improving skin tone, texture,
and elasticity and reducing wrinkles. The present manuscript summarizes the recent update on the
anti-aging potential of GT and its possible mechanisms. The literature survey suggested that GT
consumption is linked to improved cognition, reduced depression levels, and activation of pathways
in model organisms like C. elegans. Additionally, tea polyphenols enhance fibroblast mitophagy,
boost hippocampal synaptic plasticity in rodents, and mitigate age-related cognitive decline. Moreover,
EGCG exhibits anti-aging properties by reducing TNF-induced MMP-1 expression, suppressing
ERK signaling, and inhibiting MEK and Src phosphorylation in human dermal fibroblasts. In the
context of skin permeation and deposition, optimized transpersonal formulation (TF) incorporating
EGCG and hyaluronic acid (HA) demonstrated significantly increased skin permeation and deposition
of EGCG compared to plain EGCG. Furthermore, EGCG protects cardiomyocytes via the
PPARγ pathway and combats age-related muscle loss through miRNA-486-5p regulation, AKT activation,
and FoxO1a-mediated expression of MuRF1 and Atrogin-1. In conclusion, the regular consumption
of GT holds promise for promoting physical and mental health, delaying brain and skin
aging, and improving overall health by enhancing total antioxidant capacity.
