Salicylic Acid/Allantoin/Tranexamic Acid/Panthenol

Perfect Care from The Root Cause to Traces

Double care for skin troubles and scarring for problematic skin

The main ingredient, allantoin, is highly effective at calming, 

healing, and soothing oily and acne-prone skin, all while repairing and protecting it.

Another key ingredient, BHA, helps reduce excessive sebum production by inhibiting the bacteria causing inflammation. U1 is the specialized care ampoule for addressing acne-related issues 

and skin troubles while also aiding in the repair of damaged skin.

To facilitate deep absorption of the ampoule, apply it using cosmetic devices or specific techniques (massaging). 

Depending on your skin type or specific concerns, 

you can also mix and apply other U-line ampoules as a booster for targeted skincare and additional benefits.
