FAQ
What does the "triple-synergy" in ABC actually mean?
ABC combines three active ingredients — Azelaic Acid (10%), Niacinamide (5%), and Centella Asiatica (1%) — that work together rather than relying on one ingredient alone. Each targets a different concern: Azelaic Acid for the appearance of blemishes, Niacinamide for uneven tone, and Centella Asiatica for barrier support, so the formula feels balanced rather than harsh.
Is this serum gentle enough for sensitive or acne-prone skin?
Yes — ABC was specifically designed for acne-prone and oily skin, with a lightweight gel texture. In clinical testing, it showed an 18.05% improvement in soothing effect and up to a 151.90% improvement in skin barrier condition on physically stressed skin.*
*Based on clinical testing conducted by ACE Skin Clinical Research Institute. Testing duration and participant numbers vary by study. Individual results may vary.
Why does my serum sometimes have a white residue on the bottle or skin?
This is normal and doesn't affect how the product performs. Due to the high concentration of active ingredients, a light white residue can occasionally appear — if you notice it, gently wipe the bottle opening and follow with a moisturizer to help support absorption.
Can I use ABC with other active ingredients, like Vitamin C or PHA?
We don't recommend layering ABC with other low-pH acid ingredients, such as PHA or Vitamin C, as combining actives can increase the likelihood of irritation. Use ABC on its own at night, and save other actives for a different part of your routine.
