Mediheal (Korean: 메디힐; often stylised as MEDIHEAL) is a South Korean skincare and cosmetics brand best known for its sheet masks, targeted skincare treatments, and dermatologist-inspired “beauty science” positioning. The brand is operated by L&P Cosmetic Co., Ltd., headquartered in Gangseo-gu, Seoul. Launched around 2009, Mediheal has developed from a mask-focused Korean beauty label into an international skincare company with products sold across numerous markets, including Singapore.1

The company’s official website identifies L&P Cosmetic as the operating entity and Kwon Ohseop as CEO.2

Mediheal occupies a distinctive position in the Korean beauty (K-beauty) industry. Rather than initially competing across every cosmetics category, the company concentrated heavily on the facial sheet mask. This focus became one of its primary competitive advantages. The brand’s fundamental proposition was to transform intensive skincare treatments, traditionally associated with clinics or elaborate routines, into affordable, convenient, single-use treatments for home use. The company describes this philosophy as creating an affordable “one-sheet solution” for evolving everyday skincare needs.3

While the brand has since expanded into a broader range of skincare products, masks remain central to its identity.

Founding and early development

The history of Mediheal is closely linked to L&P Cosmetic Co., Ltd., which was established on 22 April 2009. The company was founded by Korean businessman Kwon Ohseop, who possessed prior experience in the cosmetics industry and came from a family with a background in the sector.4

Kwon’s mother, Yoo Im-soon, had established Wangsang Chemicals in 1969, forming part of the corporate lineage behind L&P Cosmetic. Kwon later founded L&P Cosmetic following earlier business experiences, including a venture during the Korean financial crisis era.5

Mediheal’s historical materials describe 2009 as the beginning of its mask revolution. At that time, sheet masks were not yet the ubiquitous K-beauty staple they would later become. Mediheal identified an opportunity to position masks as a practical, regular skincare treatment rather than an occasional novelty or promotional item.6

Timeline clarification

Historical records present slightly different dates regarding the company and brand launch:

• 2009: L&P Cosmetic was established.
• 2009: Development of Mediheal’s mask-focused business began.
• Some corporate materials cite 2011 as the specific brand launch year.
• By the early 2010s, Mediheal was firmly established as L&P Cosmetic’s flagship skincare brand.6

Consequently, 2009 is generally regarded as the inception of the Mediheal/L&P enterprise, while 2011 is sometimes referenced as the milestone for the specific brand launch.

Original business idea

Mediheal’s early strategy was unconventional for its time. In 2009, facial masks were frequently treated as supplementary or novelty items rather than the core of a skincare business. Mediheal instead centred its R&D and marketing on masks, operating on the belief that modern consumers sought skincare that was fast, convenient, targeted, easy to use, affordable, and supported by science.

The sheet mask format suited this concept effectively, delivering a concentrated dose of formulated essence or serum with minimal effort. Mediheal describes this approach as transforming the mask from a novelty into a professional, targeted treatment, which became the foundation of the brand’s identity.

“Beauty Science”

A central branding concept for Mediheal is “Beauty Science.” The company positions itself as a skincare brand combining ingredient research, formulation expertise, dermatology-inspired knowledge, material technology, product testing, and continuous R&D. This distinguishes it from brands that rely primarily on imagery, fragrance, or lifestyle marketing.

Its stated philosophy follows a clear trajectory: identify a skin concern, formulate a targeted solution, and deliver it conveniently to consumers. The company explicitly describes itself as a “beauty science” entity, emphasising the scientific processes behind its product development.7

More recent branding has also adopted the concept of “The Simplified Derma,” reflecting a shift towards simplified, dermatologist-inspired skincare beyond masks alone.8

Sheet masks

Sheet masks are the product category that established Mediheal’s reputation. Instead of producing generic masks, the brand developed formulations around specific skin concerns and active ingredients, including hydration, dryness, skin barrier support, blemishes, calming, brightening, dullness, pores, firmness, and signs of ageing.

The brand has also experimented with various sheet materials, delivery systems, and formats. During its first decade, Mediheal developed more than 250 unique sheet masks, including charcoal masks, acupressure-inspired masks, 3D ampoule masks, two-step treatments, and masks using specialised sheet materials.910

Current international offerings include dozens of mask products across different formats, such as N.M.F., Teatree, Madecassoside, Vitamin C, Ceramide, Collagen, PDRN, Hyaluronic-acid, Retinol, and specialised gel masks.11

Expanded categories

While masks remain the most recognisable products, the modern Mediheal portfolio is considerably broader:

• Toner pads: Pre-soaked pads designed to combine toner application, exfoliation, hydration, or targeted treatment.
• Serums and ampoules: Concentrated skincare products designed to complement mask usage.
• Patches: Targeted treatments including blemish patches and eye patches.
• Cleansers and daily care: Conventional skincare categories for daily maintenance.

The current product catalogue contains more than 100 products across masks, pads, serums, and other skincare categories.12

N.M.F.

N.M.F. (Natural Moisturizing Factor) is one of Mediheal’s most recognisable concepts. Associated primarily with hydration and moisture care, this line helped establish the brand internationally. The N.M.F. Ampoule Mask remains listed among the brand’s flagship and bestselling products.13

Teatree

The Teatree line focuses on skin prone to blemishes or irritation, emphasising calming and moisture balance. Current products include the Teatree Essential Mask Calming Moisture, Teatree pads, and other related treatments.14

Madecassoside

This ingredient-centred line is associated with soothing, barrier repair, and blemish-oriented skincare. Mediheal currently offers Madecassoside masks and modelling-pack products.15

Collagen

The collagen range is positioned around firming and skin elasticity, comprising both collagen masks and gel-mask formats.16

R&D is central to Mediheal’s brand identity. Historically, the company has experimented with both formulation and physical mask construction rather than simply updating packaging. Innovations have included new essence formulations, specialised ingredients, diverse sheet materials, improved adhesion, 3D structures, two-step treatments, charcoal sheets, and concentrated treatment formats.

Having created over 250 different sheet-mask concepts and formulations in its first decade, Mediheal helped transform the sheet mask into a versatile product platform rather than a single product type.9

Growth in South Korea

Mediheal’s rise coincided with the rapid expansion of K-beauty. As Korean consumers increasingly sought affordable, ingredient-focused skincare, the local retail ecosystem provided brands like Mediheal access to a substantial consumer base.

The brand became particularly associated with Olive Young, South Korea’s major health and beauty retail chain. Company data indicates that Mediheal masks achieved the top cumulative sales position among masks at Olive Young from 2011 through 2024/2025.17 This retail exposure was significant, as Olive Young evolved into a key distribution and trend-setting channel for modern K-beauty, operating more than 1,380 stores as of December 2025.18

International expansion

Mediheal subsequently expanded outside South Korea into markets including China, Hong Kong, Japan, Singapore, the United States, Taiwan, Malaysia, Australia, and Canada.19 The brand benefited from the global popularity of K-beauty during the 2010s, when Korean skincare concepts such as multi-step routines, sheet masks, essences, and targeted ingredients gained international traction.

The United States emerged as a particularly important market. By 2025, Mediheal reported reaching 3.1 billion mask packs sold globally and had grown to approximately 240 employees.19 More recent communications state that sheet masks had reached more than 3.1 billion cumulative units across more than 44 countries by 2025.20

Business model

Mediheal’s business model can be summarised as: Science → targeted skincare concern → accessible treatment → mass distribution. The company operates between several traditionally distinct segments:

• It is not purely a luxury cosmetics brand, as products are designed for frequent, accessible use.
• It is not purely a pharmaceutical or dermatological company; despite its “derma” positioning, it is fundamentally a cosmetics and skincare business.
• It is no longer purely a sheet-mask company, having expanded into pads, serums, patches, cleansers, and other skincare.

This combination allows Mediheal to retain its original identity while broadening its addressable market.

Brand identity themes

Mediheal’s identity is defined by several key themes:

1. Accessible professional skincare: Making clinic-associated treatments available for home use.
2. Ingredient-led formulation: Organising products around recognisable ingredients such as tea tree, hyaluronic acid, collagen, vitamin C, ceramides, madecassoside, retinol, and PDRN.
3. Targeted solutions: Structuring products around specific skin concerns rather than generic claims.
4. Convenience: Leveraging the inherent ease of the sheet mask format (open, apply, wait, remove).
5. Scientific credibility: Emphasising dermatology, R&D, and formulation to maintain a clinical identity distinct from traditional cosmetic brands.21

Mediheal played a significant role in normalising the sheet mask as an everyday skincare product. Prior to the global K-beauty boom, sheet masks were not necessarily a daily staple in Western skincare routines. Mediheal popularised the model where one mask equals one concentrated skincare treatment.

This concept proved highly compatible with social media and modern beauty retail due to the products’ visual recognisability, affordability relative to professional treatments, ease of demonstration, and wide availability. Consequently, Mediheal became strongly associated with the global K-beauty sheet-mask phenomenon.

Corporate structure

Mediheal is a brand of L&P Cosmetic Co., Ltd. The official website lists the headquarters at 516 Gonghang-daero, Gangseo-gu, Seoul, Republic of Korea, and identifies Kwon Ohseop as CEO.22 Trademark records confirm L&P Cosmetic Co., Ltd. as the holder of the MEDIHEAL trademark.25

Social responsibility

Corporate social responsibility forms part of the company’s narrative. L&P/Mediheal’s history connects to the business legacy of founder Kwon Ohseop’s mother, Yoo Im-soon, and the company describes philanthropy as integral to its management philosophy. Notably, Kwon reportedly donated 14.4 billion Korean won to Korea University, his alma mater, alongside other community development activities.23

• 1969: Yoo Im-soon establishes Wangsang Chemicals, creating the corporate lineage behind L&P Cosmetic.24
• 2009: L&P Cosmetic is established on 22 April; Mediheal begins its mask-focused skincare journey.25
• 2010: The company registers a utility-model patent for a two-step facial mask.26
• 2011: Mediheal becomes established as a major branded product and expands through Korean beauty retail, including Olive Young.27
• 2012–2013: Expansion through Korean duty-free retailers and broader international distribution begins, covering markets such as the United States, Japan, Singapore, Australia, and Canada.
• 2010s: Mediheal becomes increasingly associated with the global rise of K-beauty and sheet masks.
• 2020s: The brand expands beyond conventional sheet masks into pads, serums, patches, gel masks, and other skincare formats.28
• 2025: Mediheal reports more than 3.1 billion mask packs sold globally and approximately 240 employees.19
• 2025–2026: The brand increasingly presents itself as a broader derma-skincare and beauty-science company rather than solely a sheet-mask manufacturer.28

Mediheal’s significance in the cosmetics industry stems less from being the first to manufacture sheet masks and more from transforming the sheet mask into a scalable, recognisable skincare category. Its strategy combined Korean skincare culture, ingredient-focused formulations, targeted skin concerns, affordable single-use treatments, and aggressive retail distribution.

This combination aligned effectively with the global K-beauty boom, resulting in a brand that has sold billions of masks worldwide and become one of the most recognisable Korean skincare names internationally.29
