Even novelty filters such as Snapchat and Instagram’s, as well as adding bunny ears or specs to your selfie, plump your lips, erase your pores and lift your jowls.

1. 句子主干是：Even novelty filters plump your lips, erase your pores and lift your jowls.

2. as well as ： 也是介词，也是并列连词。在本句用作介词，后面接动名词adding。意思是“除了......之外（还）”，等于besides，apart from，in addition to 的意思，后面的plump，erase 和 lift 是3个并列的谓语动词。adding 在意义上跟这3 个动词并列，但放在介词as well as 后，变成了动名词。

我举例对比：

Tom learns to paint as well as plays football. （连词）

Tom learns to paint as well as playing football.（介词）

3. even 是一个强调副词，修饰后面的名词 novelty filters。

英语中，有些副词可以修饰名词，用以加强语气。常用的这类副词有quite,rather,even,only 等。例如：

quite the opposite 恰恰相反

We held quite a party last weekend. 上周末我们举行了一次相当不错的聚会。

Even a child won't believe such a story you told. 就连孩子都不会相信你讲的这样一个故事。
