Try also N-acetyl-carnosone drops which I think DO work

Link for the drops:

For advanced cases only an operation might help at this moment in history.

Please don’t spoil the bottle by cutting an opening with scissors……..if you don’t know what to do then ask me [it is very simple!] Anyhow, see below what to do.

Take the ring out and then screw to make an opening!

Drop twice per day if possible [ the ring I colored red, remove this]
