Os cosméticos para uso diário devem proteger os elementos celulares estritamente epidérmicos do sistema imunológico da pele, as células de Langerhans e os queratinócitos contra o fotoenvelhecimento e prevenir a alteração da função de imunodefesa da pele.
Fotocitoimunoproteção
Filtros UB e Imunofotoproteção
Complexo Fotocitoprotetor
Eficácia em Seres Humanos
A luz do sol tem tido seus adoradores há séculos, mas só muito recentemente descobriu-se seus efeitos biológicos. Alguns são benéficos: síntese da vitamina D, calor, energia, sensação de bem-estar e fototerapia clínica. Outros são prejudiciais: eritema, câncer, fototoxicidade, fotoalergia e fotoenvelhecimento. Estudos dedicados à ação da luz UV sobre o sistema imunológico - o efeito de fotoimunossupressão - datam de apenas 15 anos, embora o número desses estudos esteja agora aumentando rapidamente.13 Os comprimentos de onda UVB provocam os maiores danos ao sistema imunológico cutáneo.12
A diminuição dos níveis de ozônio na estratosfera parece ser a causa provável - a curto prazo do aumento da radiação UV no nível do solo, principalmente os comprimentos mais curtos, UVB e UVC.11
