I get the question all of the time- "How can I tell if my hazelwood is still good?". Well, the best way to tell is by it's appearance. The beads will become dark and almost greasy looking.
Another thing to notice is that your symptoms will begin to reappear. I have found that the first piece of hazelwood jewelry will not last as long as the following ones. This is because the first one has to work the hardest!
I like to wet my hazelwood necklace every so often and wear it. I feel that this brings faster results. It takes my acne almost a full 2 weeks to subside after I start wearing it. I was wearing a Baltic amber necklace with an all hazelwood extender for a while, but evidently it was not enough. I have switched back to the full hazelwood necklace and the effects are jawdropping! I am reminded why I fell in love with it in the first place. This is me fresh faced. The left picture was taken last fall and the one on the right was today. No filters!
