The official Cos De Baha website identifies Sung Il Park and Jun Won Lee as the brand’s founders. Park initiated the brand by launching products through the US Amazon marketplace and continues to maintain the brand’s US trademark rights.

Cos De Baha was established in 2019 in South Korea. Unlike many established Korean beauty companies that grew through department stores, physical retail, or large cosmetic groups, Cos De Baha’s early expansion was closely tied to online commerce, particularly the US Amazon marketplace. The brand cites Amazon as a critical starting point for its international presence.

This online-first strategy is central to the brand’s identity. Cos De Baha has consistently emphasised the contents of the bottle—specifically the concentration and type of active ingredients—rather than luxury packaging or celebrity-driven marketing. Independent skincare commentary similarly characterises Cos De Baha as a relatively young, digitally native Korean skincare brand built around high-concentration, active-focused products and comparatively low prices. 2

The brand identifies Sung Il Park and Jun Won Lee as its founders. According to the company’s official history, Park was responsible for initiating the product launch on Amazon in the United States.

Current official Korean corporate information lists JAINA Co., Ltd. (주식회사 제이나) as the operating entity, with Jun Won Lee serving as CEO. The registered corporate address is located in Paldal-gu, Suwon, Gyeonggi-do, Republic of Korea.

Cos De Baha states that its products are manufactured in South Korea by a specialised skincare manufacturer with more than 30 years of industry experience.

The core philosophy of Cos De Baha centres on combining high active-ingredient concentrations with straightforward formulations and affordable pricing. The company develops products based on ingredients investigated in scientific literature, aiming to utilise beneficial raw materials while avoiding unnecessary additives and production costs. By reducing expenses in production and distribution, the brand maintains reasonable retail prices. 1

This positions Cos De Baha differently from premium Korean skincare brands; rather than selling a luxury experience, the value proposition is strictly “ingredient-first” skincare. The catalogue includes products explicitly built around specific concentrations of active ingredients, including:

• Azelaic acid
• Niacinamide
• Vitamin C
• Salicylic acid
• Retinol
• Bakuchiol
• Hyaluronic acid
• Peptides
• Ceramides
• Centella asiatica
• Tranexamic acid
• AHA acids

The current catalogue has expanded significantly beyond its original serum-focused identity. 4

A defining characteristic of Cos De Baha is the use of ingredient names and concentrations in product descriptions. Products are marketed around specific formulations such as Niacinamide 10%, Azelaic Acid 10%, Vitamin C 15%, or Salicylic Acid 2%. This naming convention allows ingredient-conscious consumers to easily compare products against other skincare options. 1

The company designs formulas to address specific skin concerns rather than fitting into broad cosmetic categories. The stated objective is to provide targeted solutions for different skin types and issues while keeping routines relatively simple. 1

Serums

Serums form the core of the Cos De Baha identity. The brand offers an extensive range of single- or multi-active serums targeting concerns such as acne, blemishes, excess sebum, hyperpigmentation, uneven skin tone, redness, visible pores, texture irregularities, dehydration, and signs of ageing. Best-known formulations include those featuring azelaic acid, niacinamide, vitamin C, salicylic acid, retinol, and peptides. 1

Toners

Cos De Baha produces treatment-oriented toners centred on ingredients such as niacinamide, azelaic acid, and AHA/BHA compounds. 4

Creams and Moisturisers

The product line has expanded to include creams designed for hydration, barrier support, soothing, and anti-ageing. Current offerings include ceramide-based moisturisers, azelaic acid creams, centella-based products, and peptide creams. Notable examples include the M.A Peptide Cream, which contains Palmitoyl Tripeptide-1, Palmitoyl Tetrapeptide-7, and Acetyl Hexapeptide-8, alongside niacinamide, sodium hyaluronate, and panthenol.

Niacinamide

Niacinamide is one of the most prominent ingredients in the Cos De Baha portfolio. It is used in products addressing uneven skin tone, excess sebum, enlarged pores, and general skin conditioning. The catalogue includes multiple products built around relatively high concentrations of this ingredient. 1

Azelaic Acid

Azelaic acid is a cornerstone of the brand’s range. Cos De Baha offers several azelaic acid products at varying concentrations, including 5%, 10%, 15%, and 20% formulations, depending on the specific product and current lineup. These target blemishes, redness, uneven pigmentation, and overall skin clarity. 3

Vitamin C

The brand produces concentrated vitamin C products, including a 15% pure vitamin C serum listed in its Korean catalogue. The company notes that vitamin C products may naturally yellow due to oxidation and recommends replacing the product if it turns brown. Storage away from heat, humidity, and direct sunlight is advised.

Retinol and Bakuchiol

Anti-ageing products feature combinations of bakuchiol and retinol. The Korean catalogue lists formulations containing 0.15% and 0.02% retinol respectively.

Hyaluronic Acid

Hyaluronic acid is utilised across hydration-focused products. The current lineup includes a Pure Hyaluronic 1% / 10,000 ppm Serum, as well as products combining hyaluronic acid with other actives.

Peptides

Peptides are a key component of the anti-ageing range. The M.A Peptide Cream combines multiple peptides with niacinamide, hyaluronic acid, adenosine, panthenol, and caffeine.

Cos De Baha markets itself as a cruelty-free and vegan-friendly brand. The official website states that neither products nor ingredients are tested on animals. The brand also describes its approach as clean beauty, excluding parabens, sulphates, and artificial fragrances while adhering to vegan and cruelty-free principles.

It should be noted that “clean beauty” is not a universally standardised regulatory category; in this context, it represents the brand’s own positioning rather than an independently regulated certification.

Cos De Baha is a Korean-made skincare brand. Products are manufactured in South Korea by a specialised facility with over three decades of industry experience. While the brand belongs to the broader K-beauty industry, its philosophy differs from the minimalist, moisturising, and layering-oriented image often associated with mainstream K-beauty. Instead, Cos De Baha aligns more closely with the active-ingredient and derma-cosmetic segment of Korean skincare.

Ingredient concentration is a primary selling point. The official Korean product catalogue identifies specific strengths, including:

• Vitamin C: 15%
• Niacinamide: 5% (NT toner)
• Bakuchiol + Retinol: Various concentrations
• AHA + BHA: Various concentrations
• Hyaluronic Acid: Seven types in HG cream
• Centella Asiatica: Featured in CG gel cream

The brand periodically reformulates or updates products. In a 2022 announcement, Cos De Baha stated it was updating ingredient notation to international standards and adding detailed information on composite raw materials. During such transitions, products made under old and renewed formulations may temporarily coexist. Consequently, the formula of an older Cos De Baha product may not be identical to the current version.

The visual identity of Cos De Baha is utilitarian and ingredient-focused. Product names frequently incorporate abbreviations and active-ingredient concentrations rather than elaborate marketing titles, reinforcing the position that the formula itself is the primary selling point. The company has implemented packaging and design updates over time, meaning consumers may encounter different bottles or labels for products within the same line.

Although based in South Korea, Cos De Baha has maintained a strong international orientation since its inception. The founder specifically identifies the US Amazon marketplace as a key launch platform. Current websites and catalogues reflect an international-facing business, with official materials describing recognition and distribution in markets including North America, Europe, and Southeast Asia. This e-commerce-oriented development is fundamental to the brand’s growth story.

Cos De Baha occupies a niche between traditional mass-market skincare and premium clinical skincare. Its positioning can be summarised as Korean skincare combined with high active concentrations, simple formulas, and affordable pricing. The brand competes primarily on ingredient transparency, concentration, and price rather than luxury, celebrity endorsement, or elaborate packaging.

This approach appeals to consumers who understand skincare ingredients and select products based on specific concerns—for example, seeking azelaic acid specifically rather than a generic blemish serum.

Cos De Baha has developed a following among ingredient-conscious consumers, particularly those seeking relatively inexpensive products with high percentages of individual actives. Key factors driving this appeal include:

• Relatively high concentrations of recognisable active ingredients
• Broad range of treatment-oriented products
• Korean manufacturing standards
• Accessible pricing
• Straightforward, ingredient-focused marketing
• Extensive serum selection
• Availability through international e-commerce channels

Independent commentary has described the brand as an “Amazon-first” skincare line built around high-concentration, single-active products and affordable pricing. 2

The high-concentration approach requires careful usage. Cos De Baha warns that some products contain potent levels of active ingredients and that users, particularly those with sensitive skin, may experience reactions such as burning or allergies. Higher percentages do not automatically equate to better results for every individual. Active ingredients such as acids, retinoids, and high-strength vitamin C often require appropriate introduction, frequency management, and sun protection. The brand is best viewed as an active-treatment skincare line rather than a collection of gentle everyday moisturisers.

Cos De Baha is a Korean, ingredient-driven skincare company that democratises high-active formulations. Founded in 2019 by Sung Il Park and Jun Won Lee, the brand established an international presence through online commerce and became recognisable for affordable serums containing niacinamide, azelaic acid, vitamin C, salicylic acid, and retinol. 1

The brand’s philosophy involves identifying a skin concern, selecting an associated active ingredient, formulating it at a meaningful concentration, and offering the product at an accessible price. Today, the portfolio has expanded beyond serums to include toners, creams, moisturisers, and complex multi-active formulations. 4 Within the wider K-beauty landscape, Cos De Baha maintains a distinctive position focused on active ingredients, concentrations, functionality, and affordability rather than luxury or lifestyle branding.
