Jurlique's AHCs are water soluble essential oil formulations that are meant to be diluted in water and applied to skin pre-cleansing.
I use this product in the mornings-I fill a small bowl with warm water and add ~5 drops of concentrate...I saturate a muslin cloth/washcloth with the solution and apply to my skin rubbing lightly. It's all I need to cleanse in the morning. The Ultra Sensitive AHC has extracts of lavender, calendula, and almond....this also contains a bit of witch hazel and alcohol, but since it's meant to be diluted, it hasn't affected my skin badly in any way. I don't think I'll repurchase however because I miss using my regular cream cleanser...this product is meant to prep the skin before cleansing, but I feel all it does really is add scent/aromatherapy benefits.
