zinc oxide 19%
Description
Zinc oxide is a versatile and widely used inorganic compound in skincare formulations, particularly in sunscreens. At a 19% concentration, it provides robust broad-spectrum protection against both UVA and UVB rays. This mineral-based active ingredient works by sitting on the skin's surface and reflecting, scattering, and absorbing harmful ultraviolet radiation.
Unlike chemical sunscreens, zinc oxide offers immediate protection upon application and is less likely to cause skin irritation, making it suitable for sensitive skin types. Its non-comedogenic properties also make it appropriate for acne-prone individuals. Zinc oxide exhibits antimicrobial and anti-inflammatory properties, potentially aiding in wound healing and reducing skin redness.
In sunscreen formulations, a 19% concentration of zinc oxide typically provides a high SPF rating, often exceeding SPF 30. However, the exact SPF depends on the overall formulation and other ingredients present. This concentration also ensures significant UVA protection, crucial for preventing premature skin aging and maintaining skin health. While zinc oxide can sometimes leave a white cast on the skin, modern formulations often use micronized or nanoparticle versions to improve cosmetic elegance and reduce this effect.
