Sorry for being unactive these days/weeks. I've been studying for a resit a week ago as well as looking for a job for when university starts. Still looking for a job.
One of my friends have recently bought makeup. Not ordinary makeup, fake makeup. She purchased these from ebay.
M.A.C Hello Kitty Eyeshadow:
Packaging looks legit right?

Unravel the packaging:

Again, the logo looks legit. Open the lid and:

I don't remember M.A.C releasing a 5 eyeshadow palette for this series and the lid being transparent.
The palette and back of the packaging:

The bar code is in the wrong place. It should be on the side and not on the back. I don't remember there being a sticker "001". The name on the barcode is wrong.
Below is a swatch of the palette:

The feeling of this is soft. Eventhough the colours are shimmery and are pigmented, I wouldn't use this on my skin, never mind my eyes. The reason being is that who knows what sort of chemicals are in these. I don't think this is meant to be a replica of the actual M.A.C Hello Kitty Dolly Eye or Midnight Tom. If it was meant to be a replica then it would have the shades of the actual product but more toxic.
Benefit Blush Powder in Thrrrob:

You wouldn't tell that this product is fake would you? You get the brush, protective cover (not shown in the picture) and the powder.
To determine if this product or any other Benefit Powder Blush is a fake, the first thing I would suggest is to look at the back:

Where it says "PEEL HERE", peel it.
It will do this if, it is a fake:

In a real Benefit Powder Blush, it will be easier to peel and will be able to stick back on ready for re-peel. As for the fake, the label is just stuck onto the box. It's like peeling a sticker and will not be able to be stuck down again. Eventhough that there are writing on this sticker, it shouldn't be stuck together like the image above. You will not be able to stick it back down plus its made of paper, not the actual plastic paper thing. Not sure what it is called.
This is a swatch of the "blush":

This is chalky, very chalky. It's will look chalky when applied. It also has a chalky smell. With the actual product, it will have a flowery scent.
I remember reading that people, who have bought the fake off ebay and used it, have broke out from it. The same with other fake Benefit Powder Blush.
Another product bought on ebay:

"Smashbox" eyeshadow pencil

A close up of the logo. Straight away, I recognised that this was a fake. The main giveaway is the font style. The font style used here is in serif and the actual logo uses sans-serif. Another giveaway is the capitalisation of the "S". Smashbox is all in lowercase.
Also the packaging is cheap.
Swatch of the 6 eye pencils:

Beautiful pearly colours right?
I'm not sure if this is trying to recreate a current smashbox product. I think the attempted "smashbox" logo is just applied onto it.
These fakes are probably manufactured in China. There is a chance of the cosmetics being fake on ebay especially if its M.A.C cosmetics, Bobbi Brown, Smashbox and Benefit.
Tips:
If buying cosmetics on ebay:
- If the image is small/is a stock image, ask for more images, especially actual ones.
- Look at their feedback to see if their sellers have commented on the product being fake.
- Always do your research on the products you're wanting to purchase e.g. the logo, packaging, applicators etc.
- Google the product. If it never existed or theres no promotion from the company then it is likely to be a fake.
- Check the packaging for any spelling mistakes or tranlation mistakes. If there are any mistakes then it's 100% fake.
- Look at whether the colours have been released. E.g. If a collection sold only 6 shades and the ebayer sells more than 6 shades of this collection, they are fake.
- Look at the name of the product and research. If cosmetics are numbered 1, 2, 3 etc, they tend to be fake.
- If bought on ebay and are unsure afterwards, when it arrives, take it to a makeup counter and compare.
- If a fake is bought, never use it. Throw it staight in the bin. You don't know what chemicals are in it and it may give you infections.
- Things that are being sold from China, there are a chance of it being fake.
- To avoid all of this drama, do not buy on ebay.
- Always buy instore or on the company's store.
I've added more items such as tops, caps etc on ebay:
