Ingredient Glossary

A naturally occurring molecule present in every living cell, used in K-beauty formulas for its impressive anti-aging properties. Adenosine signals skin cells to produce more collagen and elastin, visibly smoothing fine lines and firming the complexion over time. It is recognised by Korean cosmetic regulators as a functional cosmetic ingredient.

The dried leaves of Camellia sinensis — the same plant used for your morning cup of tea. In skincare, its potent antioxidants (particularly EGCG) neutralise free radicals, calm inflammation, and help regulate oil production. It is the hero ingredient in our Hydrating Teaism mask.

A creeping herb native to tropical Asia and a cornerstone of Hanbang — traditional Korean medicine. Its pentacyclic triterpenoids (asiaticoside, madecassoside, asiatic acid, madecassic acid) repair the skin barrier, suppress inflammatory signaling via the NF-κB pathway, and stimulate collagen synthesis through the TGF-β/Smad pathway. The "cica" shorthand in K-beauty is a contraction of cicatrix — a nod to the plant's centuries-long wound-healing history.

Known in Korean as ssuk (쑥), mugwort is one of the most culturally embedded plants in Hanbang — traditional Korean medicine — used for centuries in moxibustion therapy, medicinal baths, and topical skin treatment. Its flavonoids (quercetin, isoquercitrin) and phenolic acids deliver potent anti-inflammatory, anti-itch, and antioxidant effects, making it a key K-beauty ingredient for sensitive, atopic, and reactive skin.

A form of Vitamin B3 found in all three Jindelle masks. Niacinamide strengthens the skin barrier, regulates sebum production, and visibly reduces the appearance of pores and uneven skin tone. It is one of the most studied and well-tolerated multitaskers in modern skincare.

Polydeoxyribonucleotide — DNA fragments extracted from salmon (or plant sources in vegan formulations) and purified for cosmetic use. PDRN activates the adenosine A2A receptor to suppress inflammation, promote collagen synthesis via VEGF, and support cellular repair through the nucleotide salvage pathway. Documented anti-melanogenic effects — inhibiting tyrosinase and MITF expression — make it particularly relevant for post-blemish brightening. On ingredient labels it always appears as "Sodium DNA," a single INCI name that covers both PDRN and the closely related polynucleotide (PN).

The Damask rose (Rosa damascena), cultivated in Bulgaria's Rose Valley for centuries, is one of the most prized botanicals in both perfumery and skincare. Its extract delivers gentle hydration, anti-inflammatory soothing, and a natural fragrance without synthetic additives. It features in all three Jindelle masks as the binding thread of the collection.
