Key ingredients
These are the ingredients Beauty of Joseon highlights for this product, cross-checked against general dermatological and cosmetic-chemistry sources, not a full INCI list.
Fragrance: The brand's ingredient list (matched on Sephora's own page) and its official fragrance FAQ show no fragrance. Sephora's page also carries a line saying it contains less than one percent synthetic fragrance, which conflicts with those and which we could not reconcile (checked 2026-10-07).
| Ingredient | What it is | What it does for skin |
|---|---|---|
| Niacinamide | A form of vitamin B3, one of the most studied ingredients in cosmetic dermatology. | Strengthens the skin barrier by boosting ceramide production, helps even out tone by limiting pigment transfer to skin cells, and can reduce the look of enlarged pores. |
| Adenosine | A compound naturally present in skin cells, used in skincare as an anti-aging active. | Recognized by South Korea's MFDS as a functional anti-wrinkle ingredient at 0.04% concentration, based on clinical studies showing measurable fine-line improvement; a real but modest effect, not a retinoid substitute. |
| Centella asiatica extract | A plant extract, also called Cica or tiger grass, long used in traditional medicine for wound healing. | Calms redness and irritation and supports the skin barrier; some preclinical and limited clinical research suggests it may also support collagen production, though more rigorous long-term studies are still needed to confirm this. |
| PDRN (sodium DNA) | Polydeoxyribonucleotide, DNA fragments commonly derived from salmon, used in Korean regenerative skincare. | Studied for supporting collagen production and tissue repair; a newer ingredient category with a shorter independent track record than long-established actives. |
| Ceramide NP | One specific, well-studied type of ceramide used in skincare formulas. | Reinforces the skin barrier and helps it retain moisture, the same core ceramide function. |
| Beta-glucan | A polysaccharide often derived from oats or yeast. | A soothing, hydrating ingredient studied for calming sensitive skin and supporting the barrier. |
