Where can I buy this? eBay

MY 2 CENTS
I bought this for my make-up kit but unfortunately, I don’t remember what I paid for it but if you look on eBay, prices ranges between $14 & $20. The jar is pretty big and it’s very affordable.
I do remember buying it from Sugarpill, hence how I got the Goldilux Loose Eyeshadow sample.

I don’t have oily skin so really, this product is not meant for me but works perfectly for my girlfriend (who has an oily t-zone). She is definitely buying this product.
This product mattifys your face and wears for at least 5 hours without shine or oil. It’s meant to control shine. It’s colorless so it won’t alter the color of your foundation, and odorless. The powder is very fine so a little goes a long way. It shouldn’t look cakey or powdery when you apply it nor should it dull you out.
NOTE: This product is not for normal or dry skin. If you have combo skin, only use on your oily parts.

I recently changed my hair color to purple (FYI: I think purple is harder to maintain than red…) thus, I try not to wash my hair too often. After about a day and a half, my hair starts to look oily. Rather than using baby powder (the cheaper alternative), I keep my hair looking clean with Kryolan Anti-Shine Powder. I don’t like to use baby powder because of it’s scent. This product has no scent and I think does a better job of keep my hair looking fresh.

The container is large, not ideal for travelling, and it the holes release too much product. It comes with a powder puff but I prefer to use a large powder brush, to blend it better. The jar is not aesthetically appealing but I think that helps keep the price of the product down.

I would definitely repurchase this product, when needed and I know I’ll be ordering my girlfriend a jar of it soon!
