First of all – this is a product that not even many Koreans know about! So, why did I buy an anti-pollution defensor? In Korea there is a lot of pollution. I don’t only mean the trash on the street, visual pollution, sound pollution, light pollution, AIR pollution as most big cities have. Those who live in south east Asia know for a fact the real enemy is the thin powder, the Chinese dust, yellow dust, red dust, it comes with a lot of names. Coming from a clean country with clean air, and living by the sea on which I dived several times and gave me a sodium cleansing, when I arrived to Korea right away I felt the damages of this pollution type. I got asthma, skin irritation and later skin allergies. When the fine dust is severe I don’t even need to check the reports, I can just look in the mirror and I will have a bunch of infected, swollen ‘pimples’ 3 times the size of a normal acne pimple, which hurt and are red as if I had just scratched them. And so there are two things one must do: proper cleansing and proper prevention. This is, by my experience, the best prevention one can take against pollution. And it really works even just as a pore protector, even when I went back home for the summer! So, with all these characteristics I just had to try this. Oh, did I mention it also has SPF 30 PA++? It’s not enough for the summer but during the winter it does the trick.
