Zinc is scientifically validated as a key nutrient for supporting skin health. It plays a crucial role in wound healing, inflammation modulation, and the maintenance of skin integrity. Clinical studies have shown that zinc supplementation can benefit individuals with conditions like acne vulgaris, eczema, and delayed wound healing. For instance, several randomized controlled trials have demonstrated that both topical and oral zinc can reduce the severity of acne, likely through its anti-inflammatory and antibacterial properties (Dreno et al., 2014). Zinc is also essential for the function of enzymes involved in cell proliferation and repair, making it important for the regeneration of skin tissue after injury.

Furthermore, zinc deficiency is associated with dermatitis and impaired wound healing, highlighting its physiological necessity for normal skin function. The use of zinc oxide in sunscreens and barrier creams is well-established due to its protective and soothing effects on the skin. Guidelines from dermatological societies often include zinc as an adjunct therapy for various dermatologic conditions. However, while the evidence supporting zinc’s role in skin health is robust, it is important to note that its benefits are most pronounced in individuals with deficiency or specific skin conditions rather than as a general supplement for everyone.
