What brand of cosmetics or skin care products do you buy in Hong Kong? What is the biggest price difference between Hong Kong and the Mainland? The best deal?

Skin care products in Hongkong are cheaper than those in Chinese mainland, and they will be even cheaper if there is a shopping mall activity, and the shopping guide will send some trial samples (if you bring them to colleagues, you can keep them for trial). I think the price difference of each brand is different. For example, biotherm, I think, will be worse than 90 yuan, and Shiseido will be about 40% worse. Anyway, it will definitely be cheaper.

I hope I can help you!
