Zinc for Skin Wellbeing. A Mineral with Gentle Strength.
Zinc is a vital trace element that supports not only overall health but plays a foundational role in skin integrity, barrier function, and resilience.
⢠Essential for skin function: The skin is the third-largest zinc reservoir in the body. Zinc supports enzymes, DNA processes, and overall skin cell health and repair.
⢠Supports skin defence: Zinc is known for its soothing and antimicrobial support, used in forms like zinc oxide and zinc pyrithione to help protect and calm sensitive or affected skin.
⢠Visible impact in deficiency: Low zinc levels are linked with skin issues such as dermatitis, acne, delayed healing, and other specific and difficult skin conditions.
⢠Natural barrier protection: Especially when used as non-nano zinc oxide, zinc helps form a gentle, physical barrier on the skin surface, suitable for delicate or mature skin and trusted in mineral-based sunscreens.
Zinc is an essential trace element that our bodies need in small amounts every day. While it is often discussed in the context of nutrition, zincās role extends to supporting skin integrity, cellular function, and overall resilience.
In topical applications, zinc oxide (especially in its non-nano form) is known for being gentle on the skin and forming a physical barrier that is non-irritating and soothing. Unlike chemical filters, zinc sits on the surface of the skin, reflecting harmful UV rays, while at the same time calming and protecting delicate tissue.
When included in skincare, zinc can help maintain the skinās natural barrier function, support comfort in sensitive skin, and provide a protective layer against environmental elements. Its mild, non-comedogenic nature (doesnāt block skin pores) makes it suitable for a wide range of skin types, from delicate to mature.
As with all ingredients, quality matters. Non-nano zinc oxide does not absorb into deeper layers of the skin, making it a favourite for those seeking a more natural, mineral-based option in sunscreens and protective creams.
Why Zinc Matters in Skincare
⢠Forms a gentle, physical barrier on the skin, ideal for sensitive or mature skin.
⢠Recognised for its soothing, anti-inflammatory, and antimicrobial effects.
⢠Believed to aid in barrier repair, hydration, and overall skin resilience.
