Now, I'm not wearing sunscreen in this video, but if I was, those blue spots would not appear, and then when my sunscreen wore off later, the solar freckles would reappear in UV light and I would know that it was time to reapply sunscreen.
Não estou usando protetor solar nesse vídeo, mas, se estivesse, aqueles pontos azuis não apareceriam, e quando meu protetor solar tivesse desaparecido, as sardas solares reapareceriam sob a luz ultravioleta, e eu saberia que era hora de reaplicar o protetor solar.
