How it works
Named for emergency calming, this serum layers Centella Asiatica Extract with Glycyrrhiza Glabra (Licorice) Root Extract, a combination common in Korean formulas built for stressed or irritated skin, alongside Allantoin and Panthenol for immediate comfort. Sodium Hyaluronate and Polyglutamic Acid carry hydration, while Adenosine, Acetyl Hexapeptide-8, Copper Tripeptide-1 and Palmitoyl Pentapeptide-4 round out a formula aimed at skin that needs calming before anything else. It is meant to follow toner and precede a moisturizer, applied to skin that is still slightly damp so the actives have a receptive surface to absorb into. This particular listing is the 50ml size TIRTIR sells for the line, packaged and formulated for the Korean market rather than a separate US release.
Key benefits
- Centella Asiatica Extract and Licorice Root Extract for calming
- Allantoin and Panthenol for immediate comfort
- Sodium Hyaluronate and Polyglutamic Acid for hydration
- A four-part peptide and Adenosine stack
- Brought in as the exact Korean-market SKU TIRTIR sells at home, not a separate US-market formulation
Key actives
AdenosineSkin-soothing nucleoside
A naturally occurring skin nucleoside included in most modern Korean formulas for its soothing, texture-supporting role, almost always used at a low, well-tolerated concentration.
Centella Asiatica ExtractCalming botanical extract
A whole-plant Centella Asiatica extract, the calming botanical at the centre of Korean cica skincare, carrying the plant's full profile rather than an isolated single compound.
Sodium HyaluronateHumectant, water-binding
The salt form of hyaluronic acid, and the exact form this row's own ingredient list names, drawing water into the skin's surface layers for a plumper, more hydrated feel.
PanthenolProvitamin B5, soothing
Provitamin B5, a staple soothing and moisture-holding ingredient across Korean toners, serums and creams, chosen for how reliably well most skin tolerates it.
AllantoinSoothing, skin-conditioning
A mild, widely tolerated soothing ingredient long used across Korean skincare to keep a formula comfortable even when it is doing other, more active work.
When should I reach for this instead of my regular serum?
On days skin feels irritated, tight, sunburnt or over-exfoliated, this serum is built to calm first rather than layering in actives like retinoids or acids that a stressed barrier is not ready for.
Can I use this every day as my main serum?
You can, since the ingredients are calming rather than aggressive, but it is positioned as a rescue step, so many routines keep it on hand for flare-ups rather than daily use.
What should I pair this with on a bad skin day?
A simple, calming moisturizer is enough. Skip other active treatments like acids or retinoids that day and let this serum and a plain moisturizer do the work. This is general guidance rather than a fixed rule, so adjust it based on how your own skin or the product itself responds.
Is this the same formula sold in Korea, or a version made for the US market?
This is TIRTIR's Korean-market formula, sourced and shipped with its original Korean-market packaging and batch coding rather than a separate US-reformulated version. Korean Pharmacy stocks the exact SKU sold through Korean retail rather than a substitute built for US shelves, which is the point of buying from a specialist rather than a general beauty retailer.
How should I store this to keep it in good condition?
Keep the cap or compact closed between uses and store it away from direct sunlight and heat, the same way you would any cosmetic. A cool, dry spot such as a drawer or cabinet keeps the texture and finish consistent for longer than leaving it exposed on a warm windowsill or in a hot car.

How to use
- Apply a generous layer to freshly cleansed skin whenever skin feels irritated, tight or over-exfoliated, ahead of the rest of the routine rather than layered under other actives. Follow with a simple, calming moisturizer rather than additional treatment steps that day.
Worth knowing
- Introduce any new active serum gradually, a few nights a week at first, rather than daily right away.
- Follow an exfoliating or retinoid-containing serum with daytime sun protection the next morning as a separate step.

Centella can make your skin appear more hydrated, plumper and healthier.
Samantha Stein, PA-CDermatology physician assistant, Cleveland Clinic Pantothenol is a common ingredient in skin care and hair products I recommend, particularly for people who are prone to dryness.

Allantoin can tone down the dryness of the individual cells. It increases the water content of the skin, which means it helps to hydrate and moisturize.
