BK-LAB Centella-Lacto Solution Ampoule — pharma-backed calming serum
BK-LAB Centella-Lacto Solution Ampoule — pharma-backed calming serum
Skincare backed by a pharmaceutical company
BK-LAB is developed by Bukwang Pharmaceutical — one of Korea's established drug manufacturers. When a pharma company enters skincare, formulation rigor comes with it: no filler-heavy formulas, no marketing-first ingredient choices. The Centella-Lacto Solution Ampoule combines centella asiatica (Korea's leading calming botanical) with lactobacillus ferment — a live-culture derivative that has been used in Korean functional skincare for over a decade. The result is a high-actives ampoule designed for skin that reacts, flares, and stays red.
The centella + ferment pairing
Centella asiatica works at the barrier level: its triterpene compounds (asiaticoside, madecassoside, asiatic acid) inhibit the pro-inflammatory signalling that makes reactive skin redden and flare. Lactobacillus ferment works at the microbiome level: fermented bio-actives strengthen the lipid matrix of the skin barrier, reducing transepidermal water loss (TEWL) and the sensitivity that comes with a compromised barrier. Together, they address the cause (barrier weakness) and the symptom (redness, reactivity) at the same time. This is why the combination has become standard in Korean dermocosmetic formulations.
Key ingredients
| Ingredient | Function |
|---|---|
| Centella asiatica extract | Calms redness, supports barrier repair |
| Lactobacillus ferment filtrate | Probiotic-derived barrier strengthener |
| Madecassoside | Isolated centella triterpene, high-purity anti-redness |
| Asiaticoside | Supports wound healing, reduces redness duration |
| Niacinamide | Brightens, reduces visible pores, evens tone |
| Panthenol | Deep hydration and barrier repair |
| Allantoin | Soothes actively irritated skin, reduces stinging |
How to use
- After cleansing and toning, while skin is still slightly damp
- Dispense 2–3 drops into palm and warm between fingers
- Press gently into face — focus on areas of redness or sensitivity
- Allow to absorb for 60 seconds before applying moisturiser
- Use morning and evening — safe for daily use due to gentle pH profile
Who this is for
- Rosacea-prone skin that flares from retinol, acids, or fragranced products
- Post-procedure skin (after laser, chemical peel, or microneedling) — accelerates calm
- Acne-prone skin where inflammation lingers after breakouts resolve
- Anyone whose skin "gets red easily" and hasn't found a serum it tolerates

Frequently asked questions
What does "pharma-backed" mean for a skincare product?
BK-LAB is produced by Bukwang Pharmaceutical, a Korean drug manufacturer. This means the ampoule is manufactured in a pharmaceutical-grade facility (GMP-certified) with active-ingredient purity standards stricter than standard cosmetics manufacturing. The formulation team is the same group that develops dermatology-grade topicals — not a contract cosmetics lab. You are getting pharmaceutical process rigour applied to a cosmetics-regulation product.
Can I use this under prescription retinol or other active treatments?
BK-LAB Centella-Lacto is compatible with most prescription topicals. If you are on tretinoin, adapalene, or benzoyl peroxide — all of which cause initial dryness and barrier disruption — this ampoule is designed precisely for that kind of adjacent irritation. Apply it before your prescription product, or on evenings when you skip the prescription treatment. If in doubt about specific drug interactions, confirm with your dermatologist.
How long before I see results?
Redness reduction is often noticeable within 2–4 weeks of daily use — the centella and niacinamide work cumulatively. Barrier strengthening (the TEWL reduction effect from lactobacillus ferment) typically shows as reduced sensitivity and less reactive flushing after 4–6 weeks of consistent use.
Is this the same as cica cream?
Centella asiatica ("cica") in cream form is usually suspended in an emollient base — moisturising but lower active concentration. This ampoule is a concentrated solution: the centella extract and madecassoside are at serum-level potency without the heavy cream base. It layers under your moisturiser rather than replacing it. Think of it as cica delivered at clinical concentration rather than retail dose.
