La piel es la primera barrera del cuerpo frente a la radiación ultravioleta, cuya exposición excesiva puede causar envejecimiento prematuro y cáncer; en niños, este riesgo aumenta, haciendo esencial usar protectores solares, prefiriendo aquellos con filtros inorgánicos. Actualmente, las nanopartículas de óxido de zinc representan una alternativa eficaz, ya que ofrecen una defensa alta sin dejar residuos visibles, no obstante, su uso ha generado inquietudes respecto a la posible absorción, efectos a nivel celular y seguridad. Diversos estudios confirman que no penetran capas profundas cutáneas ni generan toxicidad, consolidándose como una opción para proteger la piel infantil y sensible.
Abstract
Skin constitutes the primary barrier of the human body against ultraviolet radiation, whose excessive exposure may cause premature aging and cancer. In children, this risk is higher, making sunscreens usage essential, preferably those containing inorganic filters. Zinc oxide nanoparticles currently represent an effective alternative, as they provide high protection without leaving visible residues on the skin. However, their use has raised concerns regarding potential absorption, cellular effects, and safety. Several studies confirm that these nanoparticles do not penetrate the deeper layers of the skin or cause toxicity, establishing them as a suitable option for protecting sensitive and pediatric skin.
