aoi is a Korean skincare brand. It is made by Red Purple Blue, a company based in Goyang-si, and the brand itself came to market in April 2026.
The brand starts from a question rather than from a range. No two people have the same skin, yet a ready-made set has already decided for the buyer what they need. So every aoi product is built around one concern and one key active, with its concentration printed on the bottle in both per cent and ppm.
The botanical raw material comes from Korean fields: rice, green tea and ginseng. To keep that supply stable the company signed a memorandum with an agricultural corporation in Cheorwon; it covers cultivation, sourcing, quality control, ingredient analysis and product development.
The company does not build on formulations proposed by contract manufacturers. It has its own certified research and development department, whose job is to turn research into patents and proprietary ingredients.

Drop Series
Three concentrated ampoules, each for its own concern. Lumi Drop works on tone and dark spots, Regen Drop on the skin barrier and renewal, Hydra Drop on soothing and holding moisture. They are not sold as a compulsory routine: the buyer takes the one that answers their concern and adds the others as needed. All three are stated to contain no artificial fragrance.
Drop Series
Niacinamide 5% and rice bran water
In Lumi Drop the company states niacinamide 5% (50,000 ppm), rice bran water 41% (411,600 ppm) and the rice ferment filtrate Riferm-NPG 10% (100,000 ppm). The stated action is work on tone and dark spots.
PDRN and ginseng root water
In Regen Drop the company states Sodium DNA 1.5% (15,000 ppm) and ginseng root water 42% (421,400 ppm), together with its own NB-P Complex 1% (10,000 ppm) drawn from molokhia leaf, carrot, borage and yerba mate. The stated action is barrier support and skin renewal.
Hyaluronic acid and camellia sinensis water

Skin irritation testing
For all three products in the Drop series the company supplied results from the Korea Institute of Dermatological Sciences: a twenty-four-hour closed patch test, November 2025, with a skin irritation index of 0.00 for each product.
Korean-grown material and in-house development
The company states that it looks not only at the ingredient itself but at where and how it is grown, and builds relationships with local farms. The memorandum with the agricultural corporation in Cheorwon covers the chain from field to finished product, and the formulations are developed in-house rather than by a contract manufacturer.
- 0,00
The 0.00 mark is the skin irritation index from testing by the Korea Institute of Dermatological Sciences on the three Drop products: a twenty-four-hour closed patch test, November 2025. Everything else is as stated by the company; documents are provided to the buyer on request.
- Concentrated ampoules in dropper bottles
- Three products for three separate concerns: tone, barrier and hydration
- The concentration of the key active printed on the bottle in per cent and in ppm
- Formulations with no artificial fragrance
The brand launched in April 2026 and is now preparing to move beyond Korea. The company has signed a memorandum with an overseas export distributor, filed trademark applications in Australia, Europe and the United States, and is preparing for MoCRA and CPNP requirements. Plans for 2027 include Amazon in the United States and Qoo10 in Japan, along with Cosmoprof North America. Teranova works across Latin and North America and matches the brand to the markets and channels where formulation and concentrations are the first question asked: in Mexico, Brazil and Chile pharmacy retail remains a major channel, and stated percentages read directly there.
