Zinc

Zinc is one of the most important trace minerals for skin health. Every time a skin cell divides, zinc is involved. Every time a wound heals, zinc is required. Every time the immune system responds to a skin infection, zinc plays a regulatory role. It’s present in peat as Zn²⁺ chelated by humic and fulvic acid functional groups — a form that enhances bioavailability compared to free zinc ions.

What zinc does for skin

Cell division and repair. Zinc is essential for DNA synthesis and cell proliferation. Skin cells have one of the highest turnover rates in the body, making them particularly sensitive to zinc availability. This is why zinc deficiency shows up as skin problems — slow wound healing, dermatitis, hair loss (Schwartz 2005).

Antimicrobial defence. Zinc ions directly inhibit bacterial growth, which makes zinc relevant for acne and infected skin. This antimicrobial action works alongside the broader antimicrobial effects of humic acids in peat.

Inflammatory regulation. Zinc modulates immune cell function and influences cytokine production in the skin (Schwartz 2005). This anti-inflammatory contribution complements the direct cytokine suppression by humic and fulvic acids.

How peat delivers zinc differently

Zinc supplements are taken orally and must survive digestion before reaching the skin. Zinc oxide in creams sits on the surface. Peat delivers zinc transdermally — chelated by fulvic acids that are small enough to cross the skin barrier, carrying the zinc with them directly to the cells that need it.

The chelation matters here. Free zinc ions are poorly absorbed through skin. Zinc-fulvic acid complexes have enhanced bioavailability — the fulvic acid acts as a carrier molecule, a natural mineral delivery system that evolved in bogs over millennia.

Zinc concentration in peat varies by source (10–200 ppm). Peat from deposits with higher zinc content may be particularly relevant for acne-prone skin and wound care applications.
