My friend is 美容師, she can do a simply test for you (free of charge) how to select 護膚品 in the market. Such as Lancome Vs Shiseido Vs other brand.....etc.
I think Euro brand will be better, I tried Lancome b4, quite good, in fact, it is the same manufacturer with Biotherm (Loreal).
Now, I am using the "line" from a facial shop, already more than 1 year, no big problems on face and my skin is quite "stable"...the brand name is Katherine Laurez (similar spelling) and one more brand name is Natorny.
Hope it can help, tks.
