Zinc Oxide is a white, inorganic compound widely recognized for its efficacy in dermatological care, particularly as a physical sunscreen agent. As a mineral UV filter, Zinc Oxide reflects and scatters both UVA and UVB radiation, making it a broad-spectrum sun protectant approved by global regulatory bodies, including the FDA. Unlike chemical filters that absorb UV light and can cause sensitization, Zinc Oxide sits on the skin’s surface, offering stable and photostable protection, which is especially beneficial for sensitive, acne-prone, or post-procedure skin. In skincare formulations, it is also valued for its soothing and anti-inflammatory properties, making it ideal for calming irritated or inflamed conditions such as rosacea, eczema, or diaper rash.

In haircare, while less commonly used, Zinc Oxide can play a role in scalp-soothing treatments and dandruff control due to its antimicrobial and antifungal activity. It can also act as a mild astringent, reducing oiliness without stripping natural moisture, which makes it suitable for formulations targeting seborrheic dermatitis or oily scalp issues. Its inclusion in scalp masks, medicated shampoos, and barrier creams helps to rebalance the skin’s microbiome and support overall scalp health.
