YOUR FORMULA, DECODED

WHY THIS STEP?
We didn't reach for salicylic acid. Succinic acid at 2%, alongside niacinamide at 2%, has a gentler profile and sits on 60% bamboo water instead of purified water. ACZERO™, a patented complex of seven plant extracts, is in at 1,000 ppm for the look of shine and pores, and citric acid and zinc PCA (2,800 ppm combined) with gluconolactone do the exfoliating — enough to refine texture, not enough to strip. Lactobacillus ferment lysate and Jeju yuja extract are there for a barrier that feels comfortable.
A ROUTINE THAT MAKES SENSE
When — Morning and night, after toner or pads. How — 2–3 drops over the face, pressed in gently. After a breakout, this serum first, then Vita C TRX. How often — Daily. If you use other acids, introduce this one gradually. Use sunscreen in the morning. With the other Solution serums — this one first, then Vita C TRX, then Bakuchiol PDRN, 2–3 drops each. Very sensitive or thin skin: one serum per routine — this one in the morning works well. Storage — Store in a cool place away from direct sunlight; use within 12 months of opening.

WHAT’S INSIDE
60% bamboo water, sourced in Korea, replaces purified water as the base — it leaves skin feeling calm and hydrated. Succinic acid 2% (20,000 ppm) + niacinamide 2% (20,000 ppm) — for skin that looks clearer and more even. Patented ACZERO™ 0.1% (1,000 ppm, as a complex raw material; supplier patent No. 10-2055098) — seven plant extracts (green tea, centella leaf, okinawa mozuku seaweed, bergamot leaf, pine needle, coffee seed and white willow bark) to help skin look calmer and keep the look of shine and pores in check. Citric acid (AHA) and zinc PCA, 2,800 ppm combined, plus gluconolactone (PHA) — gentle exfoliation for smoother-looking texture. Jeju yuja extract for a clearer, smoother look. Lactobacillus ferment lysate and panthenol, with ceramide NP and beta-glucan, for the feel of a comfortable barrier. Calming actives combined: 43,800 ppm.
