怎么样正确区别用instead和however

对于however/instead 的选择，常常出错。比如：

There are many waysto describe people using the word skin. If someone isthick-skinnedthey are not easily hurt emotionally. You can criticize them or be unkind to them and it simplyrolls off their back.Thin-skinnedpeople, however/instead , are easily hurt by criticism, even if it is not too severe. You have to be carefulabout what you say to thin-skinned people so as not to hurt their feelings.

这里应该用什么呢，理由是什么呢，这两个副词，该怎么样正确的选择。

however：主要强调通过增加某个让人吃惊或者进行比较的状况/评论对前面动作加以说明和修正。（强调对比让步关系）

instead 主要强调做出另外一个不同之前的一个选择。（强调取舍关系）
