They are very pricey and therefore I rarely use them, but they do really work so well! 

This product is really good for faded your dark spots. I just wish there was less packaging

Those patches really work, i did have to use it twice on one spot but definitely did lighten the discolouration, highly recommend 

I am a big fan of the Zitsticka patches, I feel that the darts actually make a difference compared to other brands. Don´t expect a miracle after one use, but if you are consistent, the spots will fade away. The only downside is the price.

The spot was a bit lighter after the application of 2/3 patches in a 2 weeks period. Nothing too crazy considering the price and considering that with time spots become naturally lighter.
