I am a fan from Singapore and SK-II is considered a skincare designed truly for Asian fair skin types. Many women in their 40s in my social circle swear by SK-II – that it makes their skin texture finer and fairer. And if you are thinking of anti-aging skincare and can shell out the money for it, SK-II is the gold standard.
On the other hand, as evident by my trust and love for the beautybrains (!), only believe in skincare ingredients that are heavily researched and have shown significance when compared to control groups for whatever attribute they were researched for. So, I love L-AA, I love niacinamide, I love retin-a, etc.
I have seen lots of SK-II’s marketing, but not really found any research papers. Can you weigh in on this?
