no, they are two different brands.
MAC is from Canada and has very good reputation in Make up.
I hope that I answered your question.

MAC:
我皮肤很白啦,所以我想买MAC的透明粉底以及粉饼,可是我在MAC的网站上看了半天,有190种颜色,看的我头发晕!如果你很有研究的话,能不能告诉我它有没有透明色的啊?如果有的话,能不能把号告诉我,我好去买,谢谢!

Ususally even if you have light-colored skin tone, doesn’t mean that you have to choose the lightest colors, they usually don’t look natural. It’s important that the color fits the skin tone of your neck. You better try it in person, but if you can’t, I can give you the name of the ones I’m usually now. My skin color is relativly light-colored, too.
 
MAC Matte Foundation: Studio Finish Matte, SPF 8 (DIN 02239310)
Powder: Blot Powder "Medium"
 
I found this combination can give you a natural look.

Sorry, I forgot to give the numbers.
Studio Finish Matte: NC35
Powder: Blot Medium.

谢谢!我刚才在网站上看了你说的那两种了!一个问题就是这两种颜色,看起来会不会的很自然啊(我的意思是说看起来还是皮肤本来的颜色,但是有透明感,較具遮暇功效)?有一个个问题就是那个散粉除了粉芯,粉盒之外,粉扑是附加在里面的还是另外买的啊?我的问题会会太多了啊?^^不好意思!谢谢!

我就在加拿大，去THE BAY找MAC的透明蜜粉。
她们居然很干脆地说：俺们的蜜粉么的透明的！

I find this combination won’t change my skin tone too much, but still make my skin look nicer. But I’m not sure if we have similar skin tone, so it’s difficult to answer that question. This type of foundation doesn’t cover very much, so, if you need something stronger, you can combine it with concealer. The one I use is Studio Finish Concealer, NW25.
 
The Powder comes together with 粉扑.
 
If you have some more questions, don’t be afraid to ask. However, I may not be able to answer immediately. I hope this information has been of help.

I’m not very sure what "透明"粉底 or 蜜粉 actually mean, but I don’t think that you can find any "透明"粉底 or 蜜粉. If you are looking for something to make your skin look nicer but doesn’t have the texture of thick makeup, then the products from MAC will be fine.
 
There are better brands, but they are much more expensive.
The price of MAC products is good considering the quality of their products.

MAC:
首先先谢谢你!还有问题就是你说的Concealer遮暇膏是在搽完了粉饼之后用的吧!谢谢!

顶!

居然还有这个牌子的化妆品~~~~~~~~~
我只知道苹果的操作系统是MAC~~~~跟视窗势不两立的那个~~~
哎~~~不是我不明白~是世界变化快~~

I usually use concealer before foundation. But I’ve heard that you can also use it between foundation and powder as well. If you really like a very natural look, you can also just use concealer and powder, without foundation. Makeup is something that you can do a lot of experiments and figure out the best way you like it. Have fun!

MAC
我今天已经买了,效果很好,谢谢你!但是我忘了买CONCEALER,所以脸上的一些痘痕还是看的到,下次再去买CONCEALER!谢谢!

MAC
还有一个问题就是上粉底一定要使用海绵吗?用手可以吗?

和teatea一样的疑问。从来不知道啊。估计暂时还不是世界名牌吧。
