How it works

Glacier water anchors the base of this serum for the cooling sensation on application, carrying Niacinamide, Adenosine and Centella Asiatica Extract for tone and calming. The formula also names Retinal directly, alongside Sodium Hyaluronate, Hydrolyzed Hyaluronic Acid and Ceramide NP for hydration and barrier support, plus a peptide group of Acetyl Hexapeptide-8, Tripeptide-1, Copper Tripeptide-1 and Palmitoyl Pentapeptide-4. 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 30ml size TIRTIR sells for the line, packaged and formulated for the Korean market rather than a separate US release.

Key benefits

  • Glacier water base for an immediate cooling sensation
  • Retinal named directly on the ingredient list
  • Sodium Hyaluronate, Hydrolyzed Hyaluronic Acid and Ceramide NP for hydration
  • A four-peptide group including Copper Tripeptide-1
  • Sold as TIRTIR's authentic Korean-market formula, the same version sold through Korean retail rather than a US-reformulated substitute

Key actives

NiacinamideTone and texture

A well-studied B3 vitamin derivative that Korean formulators lean on for evening tone and refining the look of surface texture, and it sits high enough on this row's own ingredient list to be doing real work.

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 Hyaluronate CrosspolymerCross-linked humectant

A cross-linked form of Sodium Hyaluronate built to sit on the skin's surface longer than the standard molecule, giving a more cushioned, film-forming hold of moisture.

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.

Payment and security

How to use

  1. Apply a few drops to clean skin after toner, patting it in for the cooling sensation to take effect. Because the formula contains Retinal, introduce it gradually at night to start and always follow with daytime sun protection.

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.
