Body Luminizer Body Shimmer Oil with Makeup Brush (Glistening Bronze,40 ml) By AOAZXBB
Color: Glistening Bronze
I ordered the Body Luminizer Body Shimmer Oil with Makeup Brush (Glistening Bronze,40 ml) By AOAZXBB. The kit came in a zip top baggie. I received a makeup sponge, a brush and a boxed bottle of Luminizer. There were no tamper proofing precautions. The luminizer is in a glass bottle with a pump dispenser top. The luminizer is a sparkly, thick brown liquid. The product spreads easily (I used my finger for the test) and then I used the brush to finish the supplication. There is a slight bronzing color effect after application and so, so many sparkles. This looks fantastic in the sun. After a few minutes the luminizer felt dry so I used a white towel to check for rub transfer. I rubbed moderately hard over one area where I had applied the luninizer and there was a small amount of product transfer. I would not wear this against very light colored clothing and will stick to medium or darkish colors. There is a spicy masculine scent to the product. I really like the scent. There is an expiration date of 5/27 listed on the box which at more than two years away should be ample time to use the product. At less than $8 for this kit, it is an economical way to add a little bronzing and sparkle to my spring and summer!
