Help, my jar of Smooch changed consistency! What happened?

Coconut oil melts at about 24°C. If it has become a liquid just dip your finger in and use as normal.

Will the change in consistency affect the quality of the product?

No - there are enough ingredients spread throughout the jars of Smooch if they stay hard but if yours does melt you could give it a wee swish about to mix it up again.
