this one is mainly for oil control, minimizing pores and improving uneven skin tone, you may look for NMF/ B5 / marine hyaluronic / plant derived squalane for dehydrated skin
Buffet + copper is good , I like it better than buffet , I was told by the sales (I purchased in London) the copper formula was originally from NIOD , but NIOD has more intensive copper formula now , so they put that old copper formula into the ordinary line , that’s why the buffet + copper is more expensive than rest of ordinary product . I personally will repurchase the buffet +copper
