zinc oxide
Category: UVA/UVB sun protection
Known For: SPF protection
Zinc oxide is primarily composed of zinc, a mineral element, and oxygen. Its chemical formula is ZnO, indicating one atom of zinc bonded to one atom of oxygen. In its natural state, zinc oxide occurs as a white, powdery substance. When used in skincare products such as sunscreens, zinc oxide is typically processed into fine particles that can form a physical barrier on the skin’s surface to block UV radiation.
Natural Origin:
Zinc oxide occurs naturally as the mineral zincite, which is a form of zinc oxide ore. It is primarily obtained through mining and refining processes. Zinc oxide can also be produced synthetically by heating zinc metal in the presence of oxygen. However, the majority of commercially available zinc oxide is derived from natural sources through mining and processing.
Zinc oxide is primarily obtained from various zinc ores, with the most common being zincite, hemimorphite, and smithsonite. These ores are mined from deposits around the world, including countries like China, Australia, Peru, Canada, and the United States. Once mined, the zinc ore undergoes processing to extract the zinc metal, which can then be further refined into zinc oxide through various chemical processes.
WHY WE LOVE IT
Broad-spectrum protection: Zinc oxide provides effective protection against both UVA and UVB rays, making it a valuable ingredient in sunscreens. Its physical barrier reflects and scatters UV radiation away from the skin, reducing the risk of sunburn, premature aging, and skin cancer.
Gentle on the skin: Zinc oxide is well-tolerated by most skin types, including sensitive or acne-prone skin. Unlike chemical sunscreens, which can sometimes cause irritation or allergic reactions, zinc oxide is less likely to cause sensitivity, making it suitable for even the most delicate skin.
Non-comedogenic: Zinc oxide is non-comedogenic, meaning it doesn’t clog pores or contribute to acne breakouts. This makes it an excellent choice for individuals with oily or acne-prone skin who want sun protection without risking breakouts.
Soothing and calming: Zinc oxide has natural anti-inflammatory properties, which can help soothe and calm irritated or inflamed skin. It is often used in skincare products designed to alleviate redness, itching, or discomfort associated with conditions like sunburn, eczema, or rosacea.
Safe and stable: Zinc oxide is considered a safe and stable sunscreen ingredient. Unlike some chemical sunscreens, which can degrade over time and lose effectiveness, zinc oxide maintains its UV-blocking properties, providing reliable sun protection with minimal degradation.
Suitable for all ages: Zinc oxide is safe for use on all skin types and ages, including babies and individuals with sensitive skin. It is commonly found in sunscreens formulated for children and sensitive skin, providing gentle yet effective protection for the whole family
