I heard Haba can use water for 導出 (both people said and on their web site), just wondering whether it works for la mente.
I made a trial on my husband yesterday
1st I used 蒸餾水 with my lamente do 紅外線+離子導出, the facial cotton become very yellow.
after that I used the la mente 導出 gel for 紅外線+ 超音波離子導出.
after done, his face seems very clean, and my daughters also said daddy's face better than before
