Zeroid (Korean: 제로이드) is a South Korean medical skincare and dermocosmetic brand owned and developed by Neopharm Co., Ltd. The brand specializes in products designed around skin-barrier care, particularly for dry, sensitive, reactive, oily, blemish-prone, and treatment-sensitized skin. Zeroid was launched in March 2002, originally as a moisturizer intended for use in clinics.[2]

The brand’s philosophy is centered on the idea that healthy skin begins with a healthy skin barrier. Its formulations are particularly associated with Neopharm’s proprietary MLE® (Multi-Lamellar Emulsion) technology and Defensamide™, which the company developed to support skin-barrier function and skin defense.[1]

Neopharm itself was established in July 2000, and Zeroid became one of its major skincare brands. Neopharm describes Zeroid as a “Professional Solution for Skin Health.”

Zeroid’s history is closely connected with Neopharm’s research into skin-barrier science.

Neopharm was established in Daejeon, South Korea, in 2000 as a company focused on skin science and related technologies. The company subsequently developed products aimed at sensitive and problematic skin.

2002 — Launch

Zeroid was launched in March 2002 as a moisturizer intended for clinical use. This is important to understanding the brand’s original identity: Zeroid did not begin primarily as a conventional mass-market beauty brand, but as a product associated with dermatological and clinical skincare.[2]

The brand’s name is officially described as being inspired by “zero steroid.” The concept reflects its positioning around non-steroidal skincare and barrier-focused care rather than steroid medication.[1]

Expansion of the product portfolio

Zeroid subsequently expanded beyond its original moisturizer.

• 2010: Zeroid Intensive was launched, targeting severely dry and problematic skin.
• 2012: Zeroid Dermanewal was launched for skincare following dermatological/professional treatments.
• 2014: Zeroid Pimprove was introduced for oily and troubled skin.
• 2014: Zeroid MD received Korean medical-device certification.
• 2019: Zeroid Rootheal was introduced for dry and sensitive scalp care.[1]

The brand has since developed multiple specialized product families covering facial skincare, scalp care, sun protection and certain medical-device products.

Zeroid is not an independent company; it is a brand of Neopharm Co., Ltd.

Neopharm is a South Korean skin-science company headquartered in Daejeon. Its portfolio also includes brands such as ATOPALM and DERMA-B.

Neopharm’s corporate history is particularly relevant to Zeroid because the company has invested heavily in technologies intended to reproduce or support aspects of the skin’s natural barrier structure.

The company’s history includes research into MLE technology, including a 2003 publication concerning the structural properties of MLE in the Journal of Investigative Dermatology.

Zeroid’s central concept can essentially be summarized as:

Healthy skin begins with a healthy skin barrier.

Rather than positioning skincare primarily around cosmetic effects such as whitening, anti-aging or fragrance, Zeroid emphasizes barrier integrity, moisturization, tolerance and skin comfort.[1]

This gives Zeroid a somewhat different identity from many mainstream Korean skincare brands.

Its positioning is closer to the dermatological/medical skincare category:

skin science → barrier technology → targeted formulation → clinical/dermatological use

The brand says its products are developed with dermatological expertise and are intended for sensitive and compromised skin.[1]

According to the brand itself, the name Zeroid was inspired by the phrase:

“zero steroid.”[1]

The name therefore reinforces the brand’s identity as a skincare alternative centered on barrier care rather than steroid-based treatment.

An important distinction, however, is that Zeroid is a skincare brand, not a replacement for prescription dermatological treatment. Products designed for sensitive or problematic skin should not automatically be considered equivalent to medicines prescribed for inflammatory skin diseases.

One of the most important technologies associated with Zeroid is MLE® — Multi-Lamellar Emulsion.

Neopharm describes MLE as a technology designed to create a three-dimensional, multilayered structure resembling aspects of the lipid structure of human skin. The purpose is to support the skin barrier and reduce moisture loss.[1]

The technology incorporates Ceramide-9S, which Neopharm identifies as part of its proprietary formulation technology.[1]

In simplified terms:

Traditional moisturizer

→ adds moisturizing ingredients
→ temporarily increases hydration

Barrier-focused MLE formulation

→ attempts to mimic aspects of skin-lipid organization
→ supports the barrier
→ helps retain moisture

That barrier-oriented approach is one of the defining characteristics of Zeroid.

The second major technology associated with Zeroid is Defensamide™.

Neopharm describes Defensamide as a technology that helps support the skin’s natural defense system. The company says it can promote production of antimicrobial peptides (AMPs) and help restrain proliferation of Staphylococcus aureus.

Defensamide also received a Silver award in the Innovation Zone Best Ingredient Award at in-cosmetics in 2011, according to Neopharm’s corporate history and Zeroid’s brand history.

Thus, Zeroid’s technology story can broadly be represented as:

MLE® → barrier structure & moisturization

Defensamide™ → skin defense & resilience

Together, these technologies form much of the scientific identity that Zeroid uses to differentiate itself.

Zeroid has developed a fairly broad portfolio rather than producing only one “hero” moisturizer.

Zeroid Intensive

Target: severely dry and problematic skin.

This is one of Zeroid’s richest moisturizing families. Products include creams, lotions and ointment-creams designed for intensive moisturization.[1]

The Intensive Oint-Cream, for example, combines the brand’s MLE technology with rich emollient ingredients and Defensamide. Zeroid states that the product can be used across age groups, including babies and children.[1]

Zeroid Soothing

Target: dry, sensitive and reactive skin.

The Soothing line is positioned as the relatively gentle, everyday side of the Zeroid portfolio.

Its products include:

• Soothing Cream
• Soothing Lotion
• Foaming Cleanser
• Mild Suncream

The brand describes this range as providing mild care for dry and sensitive skin.[1]

Zeroid Pimprove

Target: oily, blemish-prone and troubled skin.

Pimprove is interesting because it shows that Zeroid’s philosophy isn’t limited to extremely dry skin.

The line includes:

• Pimprove Cream
• Pimprove Gel Cleanser
• Pimprove Toner
• Pimprove SD-Care Gel
• BB Cream

Zeroid positions the line around controlling excess sebum, maintaining oil-water balance and supporting the skin barrier. The brand also states that its products have undergone non-comedogenic testing.[1]

Zeroid Dermanewal

Target: skin that has been sensitized following professional or dermatological treatments.

Dermanewal is essentially Zeroid’s post-procedure/aftercare category.

The brand describes it as a specialized line intended to help care for skin following professional treatment. Products include creams and sun-protection products.[1]

This line reinforces Zeroid’s medical-skincare positioning because its intended context is closer to dermatological aftercare than ordinary beauty skincare.

Zeroid Rootheal

Target: dry and sensitive scalp.

Rootheal expands Zeroid’s barrier-care concept from facial skin to the scalp.

The Korean Zeroid site describes it as a concentrated line for dry and sensitive scalps.

Zeroid Sun Care

Target: sensitive and problem-prone skin requiring UV protection.

Zeroid also has a dedicated sun-care category, although product availability varies by market. The global site lists sun-care products, while the current Korean site identifies Sun Care as part of the brand’s broader portfolio.[1]

An unusual aspect of Zeroid is that its portfolio extends beyond conventional cosmetics.

The Korean Zeroid portfolio includes Zeroid MD, described as an adhesive transparent wound dressing medical device, as well as SURGIANGEL PLUS, described as a topical hydrogel wound dressing intended for wound protection and scar care.

This creates a spectrum:

Cosmetic skincare

→ dermatological skincare

→ post-procedure care

→ medical-device products

That spectrum is one reason Zeroid is more accurately described as a medical skincare/dermocosmetic brand rather than simply a Korean cosmetics brand.

Zeroid’s core customer isn’t necessarily someone looking for the newest trendy cosmetic ingredient.

Its primary audience includes people looking for:

• Sensitive-skin products
• Dry or severely dry skin care
• Skin-barrier support
• Minimal-irritation skincare
• Oily/problem-skin products
• Post-treatment skincare
• Sensitive-scalp care
• Dermatologist-oriented skincare

The brand specifically organizes its products according to different skin conditions rather than using a single universal product range.[1]

A major part of Zeroid’s identity is its connection with hospitals and dermatology clinics in South Korea.

The Korean brand describes Zeroid as a medical skincare brand whose products are available through hospitals and clinics nationwide.[1]

This is significant from a branding perspective.

Zeroid’s positioning is approximately:

Korean skincare

• dermatological research

• barrier science

• clinic distribution

• specialized skin concerns

rather than:

K-beauty trends + cosmetics + influencer marketing

That distinction explains why Zeroid often has a more clinical-looking identity than typical Korean skincare brands.

Zeroid emphasizes products designed with sensitive skin in mind.

Its Korean brand materials state that its products have undergone skin-irritation testing, and the brand emphasizes confidence in its formulations.[1]

However, it is worth making a distinction between:

“suitable/designed for sensitive skin”

and

“guaranteed not to cause irritation.”

Even products formulated for sensitive skin can cause reactions in individual users.

So Zeroid’s sensitive-skin positioning should be understood as a formulation and testing philosophy, rather than a guarantee that every product will work for every person.

Zeroid began as a Korean clinic-oriented brand but subsequently expanded internationally.

The current global Zeroid site states that the brand is available in 18+ export markets, while its earlier brand history reported exports to 12 countries by 2020.[1]

International availability and the exact product lineup vary by country.

This is important because someone looking at Zeroid in Korea may encounter a substantially broader portfolio than someone purchasing the brand in another market.

Within the broader Korean skincare industry, Zeroid occupies a relatively distinctive niche.

A simplified comparison would be:

Zeroid therefore sits closer conceptually to brands such as dermatological/cosmeceutical skincare than to trend-driven K-beauty.

Its strongest differentiator is not simply “being Korean”; it is the combination of Neopharm’s proprietary technology, barrier-focused formulation, and clinical/medical positioning.

From a brand-analysis perspective, Zeroid’s strongest assets are:

1. Clear scientific identity

MLE® and Defensamide™ give the brand proprietary technologies around which it can build its identity.[1]

2. Strong specialization

Zeroid isn’t trying to solve every beauty problem. Its strongest territory is skin barrier + sensitive/problematic skin.

3. Medical credibility

Its origins in clinic use and its continuing presence in Korean hospitals and clinics reinforce its professional positioning.

4. Broad skin-condition coverage

The brand has dedicated solutions for dry, sensitive, oily, troubled, post-procedure and scalp concerns.

5. Long history

Zeroid has been operating since 2002, giving it more than two decades of development in the medical-skincare category.[1]

If reduced to one sentence:

Zeroid is a Korean medical-skincare brand built around the science of maintaining and restoring the skin barrier.

Its competitive identity comes from the intersection of:

Dermatology

↓
Skin-barrier science

↓
MLE®

↓
Defensamide™

↓
Sensitive/problem skin

↓
Clinic-oriented skincare

That is essentially the “DNA” of the brand.

[1]

Zeroid is best understood as a Korean dermocosmetic/medical-skincare brand rather than a conventional K-beauty brand.

Its foundation is Neopharm’s skin-science research, and its signature technologies are MLE® and Defensamide™. The brand began with a clinic-use moisturizer in 2002 and gradually developed into a multi-category portfolio covering severe dryness, sensitive skin, oily/problem skin, post-procedure care, scalp care, sun protection and medical-device products.

The brand’s central proposition is straightforward:

Protect the skin barrier → maintain moisture → improve skin resilience → support healthier-looking skin.

That makes Zeroid particularly relevant to consumers who prioritize skin tolerance, barrier care and dermatological credibility over trend-driven skincare.
