I have seen the product over a period of approximately 5 months, every day 2 times used, but may have not notice any improvement. For this, the packaging is really very inappropriate. The vial had on delivery oil stains on the label, was so leaky. After opening the first vial was so leaky that it was completely unfit for transport. In every trip I have packed in a small plastic bag and as well as he ensured that it remained in the vertical. Still, I had every time something afterwards by the oil in the plastic bag. On the whole therefore not recommended because the product does not fulfill its purpose and the packaging is absolutely inappropriate.
