Exactly u are right
I used to travel to Seoul very often for business and they apply many layer of makeup and also apply highlight and brown "shaping / contouring " stick to "reconstruct" their face contour and skin tone . It looks quite thick in real person but looks very good in pictures.
By the way , spa collection is very hard sell . I have a facial package there and dare not to go again as they keep on selling upgrading every single time and keep on selling top up every time.
