If you've spent the last year scrolling K-beauty TikTok, you've seen this bottle. The SKIN1004 Madagascar Centella Ampoule is one of the most-loved single-ingredient serums in the world, and the 100ml size is the cult favourite — three times the standard ampoule, half the per-ml price.
This is my full SKIN1004 Madagascar Centella Ampoule review: what it is, how it actually works on sensitive skin, how to layer it, who it's for, and whether the 100ml bottle is worth it in 2026.
What is the SKIN1004 Madagascar Centella Ampoule?
The SKIN1004 Madagascar Centella Ampoule is a 100% Centella Asiatica Extract serum sourced directly from Madagascar — no water, no fillers, no fragrance. It's the most-studied calming and barrier-repair ingredient in modern skincare, delivered in its purest form possible.
Centella (also called cica or gotu kola) is rich in four key actives — asiaticoside, madecassoside, asiatic acid and madecassic acid — collectively known as TECA. They reduce redness, accelerate wound healing, soothe acne inflammation and reinforce the skin barrier.
Key ingredients & benefits
• 100% Centella Asiatica Extract — soothing, calming, barrier-repairing.
• TECA complex (madecassoside, asiaticoside, asiatic and madecassic acid) — clinically proven to reduce redness and inflammation.
• Lightweight, water-like texture — absorbs in seconds, layers under anything.
• Fragrance-free, alcohol-free, essential-oil-free, EWG green-grade, vegan, cruelty-free.
Real results after 4 weeks of daily use
Within the first week, my persistent cheek redness dropped noticeably. By week three, post-acne marks were fading faster and my barrier could tolerate retinol on alternating nights without flaking. By week four, my skin looked calmer, plumper and more even in tone — without changing a single other product.
This is the serum I now reach for any time my skin is angry: after a flight, after a chemical peel, the morning after too much wine, or anytime I've over-exfoliated.
How to use the SKIN1004 Centella Ampoule
AM: cleanse → tone → 3–5 drops of SKIN1004 Centella Ampoule on damp skin → moisturizer → SPF.
PM: cleanse → tone → ampoule → retinol or treatment (optional) → moisturizer.
You can also mix 2 drops into your moisturizer for a barrier-boosted base, or pat onto specific red or breaking-out patches as a spot treatment.
Who it's for (and who it isn't)
Best for: sensitive skin, rosacea-prone or redness-prone skin, acne-prone skin, post-procedure recovery, retinol or tretinoin users, compromised or over-exfoliated barriers, and anyone who wants a true single-ingredient minimalist routine.
Probably not for you if: you specifically want anti-aging actives in your serum (look at retinol or peptides instead). Centella is supportive, not corrective.
SKIN1004 vs Beauty of Joseon vs COSRX centella
SKIN1004 Centella Ampoule is the purest single-ingredient option — most active, most minimalist, best for highly reactive skin. Beauty of Joseon Centella Asiatica Calming Serum adds panthenol and madecassoside for extra hydration. COSRX Centella Blemish Ampoule layers in salicylic and AHA, better for active breakouts.
If you have sensitive or barrier-damaged skin → SKIN1004 wins. For combination skin wanting glow → Beauty of Joseon. For acne-only → COSRX.
Pros and cons
Pros: 100% centella, no fillers, EWG green, vegan, layers under everything, 100ml bottle is excellent value, calms redness fast, barrier-friendly, safe with actives.
Cons: water-like texture (not for those who want a rich, glowy serum), no anti-aging actives, dropper requires steady hands.
Where to buy and is it worth it?
The 100ml SKIN1004 Madagascar Centella Ampoule is available at Lookfantastic with worldwide shipping. At around $35 for 100ml — roughly 4–5 months of daily use — it's one of the best per-ml values in K-beauty.
For anyone with sensitive, reactive, post-acne or barrier-compromised skin, this is one of the few products I would call genuinely essential. Easy yes from me in 2026.
