Alkaline Water in Skin Care: A Mini Review of Dermatological Benefits and Mechanisms

Abstract

Alkaline water has recently gained attention in dermatology due to its potential benefits in skin care, including pH modulation, antioxidant activity, and hydration support. The skin’s natural acidic mantle plays a crucial role in barrier function and microbial balance, and alkaline water may help restore pH homeostasis disrupted by environmental stressors. Additionally, alkaline water exhibits antioxidant properties that can neutralize reactive oxygen species, thereby reducing oxidative damage and inflammation associated with skin aging and various dermatoses. While preliminary studies indicate positive effects on skin hydration, barrier repair, and inflammation control, clinical evidence remains limited and heterogeneous. Safety concerns related to excessive alkalinity highlight the need for balanced formulations to avoid barrier disruption. This mini review summarizes current knowledge on the dermatological mechanisms, benefits, and limitations of alkaline water, emphasizing the importance of future research to establish standardized protocols and confirm clinical efficacy. The integration of alkaline water in cosmeceuticals and therapeutic regimens holds promise for advancing skin care.
