Skin-Nomad's Take — At a Glance
- 10% Azelaic Acid, 10% Tea Tree Leaf Water, and Kojic Acid for clearer, more even skin
- Three-mechanism approach to active breakouts and post-acne pigmentation simultaneously
- Capsule format; shake to activate before each use
If your skin clears a breakout only to leave a brown mark that outlasts it by months, you are dealing with two problems rather than one. Azelaic Acid is unusual in taking on both from a single molecule, and the PURITO SEOUL Azelaic Acid 10 Kojic Tea Tree Serum runs it at 10%, the concentration the published research sits at. PURITO SEOUL has formulated in Seoul since 2017, building its reputation on short ingredient lists that leave out anything decorative.
Key Benefits
- Azelaic Acid runs three jobs from one molecule: At 10% it inhibits tyrosinase to slow melanin synthesis, suppresses Cutibacterium acnes and the related bacteria behind breakouts, and quiets the inflammatory signalling that leaves skin flushed once a spot has gone. One active covers the breakout, the redness, and the mark, so the formula does not need three separate acids to get there.
- Adding Kojic Acid gives pigment a second block to get past: Kojic Acid at 1,000 ppm inhibits tyrosinase at a different binding site to Azelaic Acid, so the two run in parallel rather than competing for the same target. On marks that have already settled in, two independent blocks on the same enzyme is the difference between slow fading and none.
- What Niacinamide adds works at both ends of the problem: It blocks the transfer of finished melanin into surface skin cells, which is a third and separate brightening route, and it drives ceramide production in the barrier. That second part is what keeps daily acid use from leaving skin tight and reactive.
- Held in capsules, the Tea Tree arrives at full strength: Tea Tree Leaf Water at 10% carries antibacterial activity through the base, while Tea Tree Leaf Oil sits at 50 ppm inside capsules suspended in the serum rather than dissolved into it. It is a small, stable dose of a strong botanical working alongside Azelaic Acid's own bacterial inhibition.
Texture & Finish
A fluid serum carrying the tea tree capsules as fine specks visible through the bottle, which settle out between uses. It layers after cleansing and any toner, under moisturiser and, in the morning, sunscreen.
Ideal For
- Skin types: All skin types, and particularly oily, combination, and breakout-prone skin.
- Skin concerns: Active breakouts, the dark marks left behind after them, persistent redness and flushing, uneven tone, and visible pores.
- Best used by: People who clear a spot in a week and then spend four months watching the mark refuse to go with it will get the most out of treating both as one job.
FAQ
Q: How is this different from a blemish serum built on salicylic acid?
A: Salicylic acid works inside the pore, dissolving the oil and dead cells that block it, and that is the whole of its job. Azelaic Acid is the broader active, reaching the bacteria, the inflammation and the pigment in one application, and the PURITO SEOUL Azelaic Acid 10 Kojic Tea Tree Serum then puts Kojic Acid and Niacinamide behind it on the pigment side alone. The practical difference is that a salicylic serum manages congestion, while this one is also working on what the congestion leaves behind.
Q: Is Azelaic Acid an exfoliating acid like glycolic or salicylic?
A: No, and the name misleads a lot of people. Azelaic Acid works chemically inside the skin, on the enzyme that produces pigment and on the bacteria and inflammation behind breakouts, rather than loosening dead cells at the surface the way an AHA or BHA does. That is why it carries neither the sting nor the added sun sensitivity of an exfoliating acid, and why it sits comfortably in a routine that already has one.
Q: Can I use it in the morning as well as at night?
A: Yes. Azelaic Acid is not photosensitising, so twice-daily use is appropriate, and a morning application sits after cleansing and any toner or essence, under moisturiser and then sunscreen. If your evenings already run a retinoid, keep the two on alternate nights rather than stacking them, because the irritation compounds even where the actives themselves do not conflict.
The spot is the emergency; the mark is the thing you are still looking at six months later.
