Between countries like Korea, Japan or Taiwan?
Depends on which brand as well isn't it?
Whenever I am in Taiwan, I would go to Tomod to buy their local skincare.
Likewise when in Japan, then the prices for their local brands would be cheaper (much cheaper than what we get at Watsons even with discounts).
Same, when in Paris, I recall lugging back bottles and bottles of micellar water as it was super cheap!
You can check out shopee. They would have flash sales, and lots of discount coupons for ladies skincare products.
