Edit:
And I guess you haven't lived abroad outside HK much have you? I'm not referring to travels. When living in Malaysia and Thailand I had very oily skin. When I lived in Australia I had very dry skin, when I lived in England, I had perfectly normal skin, now in US, I have dry sensitive skin. The product that worked for me that's sold in UK since I had perfect skin, is not available in US, and Asia, although the brand has a presence.
lol you love assuming things don't you? sorry to disappoint you again, i worked on a cruise ship in england as a beauty therapist and owned a salon in sydney, australia.
honestly i don't buy whatever research marketing stuff you've done. different races have different skin (i insist), and different skin should be treated differently. let me give you the simplest example there is, an african person would have more melanocytes in their epidermis than you do. caucasions have more chance getting skin cancer than you do if you expose in the sun for the same amount of time. even you have the same skin type, skin condition, you live in the same city, you eat the same food, it doesn't mean you have the same skin! if it has nothing to do with race/genes then we would all have the same skin color wouldn't we?
I'm not generalize any asian skin, yes they are different. that's why their products are different in those countries. like i could find lancome with grape seed ingrediant in korea but couldn't find it in thailand.
honey, you studied "manufacturing and formulation", not A&P skin.
