Mervie machine

This is Merby, which doubles the effect when used with a face mask.

The ampoule or essence inside the pack

I feel like it absorbs better if I keep placing it on top of the mask pack while spinning the Merby.

When I usually do a face mask, after turning on both ION and ULTRA MODE

Set the intensity to HIGH and rotate through all four levels from N to W once each.

It is much more effective than just using a face mask.

It lasts quite a long time on a single charge, so it is easier to use than you might think.
