3-스타 인증마크(3-Star Seal)

3-스타 인증마크(3-Star Seal)는 도포부위의 단기적인 적용 테스트, 또는 이에 대한 대안으로써 도포 예상 부위가 아닌 다른 부위의 피부상태나 피부기능에 대한 장기적인 검사가 이루어진 제품에 부여됩니다. 예시로 페이스크림의 피부 수분 개선 효과를 팔 부위에서 테스트한 것을 들 수 있습니다. 3-스타 인증마크(3-Star Seal)는 단순한 패치 테스트와는 달리 시험 설계가 더 복잡하고 더 큰 중요성을 지닙니다. 제품의 제형 또는 성분에 변동이 없는 경우에만, 본 인증마크(Seal)를 계속해서 사용할 수 있습니다. 해당 인증마크(Seal)가 부여되는 테스트를 진행할 때, 피부 수분, 피부 거칠기, 피부 탄력도와 같은 피부 생리학적 매개변수가 포함될 수 있습니다. 이것은 더 긴 테스트 기간에 걸쳐 수행될 수 있습니다. 이와 같은 방법으로 3-스타 인증마크(3-Star Seal) 조사에 알레르기 유발 가능성에 대한 확인이 포함될 수 있습니다. (반복적인 패치 테스트의 경우 – 4-6주 이상 소요됨)

사용 예상 부위에서의 오픈 패치 테스트 또는 일회성 인체적용시험(예를 들어, 얼굴에 진행하는 페이스 마스크의 내약성 시험)도 더 큰 중요성과 더 많은 적용 기반 테스트 디자인 때문에 3-스타 인증마크(3-Star Seal)를 받을 수 있습니다. 이 시험을 위한 설계는 고객과 긴밀히 협의하여 조정되며, 관련 제품에 맞게 특별히 맞춰집니다.

3-스타 인증마크(3-Star Seal) 테스트 예시:

  • 다른 피부 생리학적 매개변수(피부 수분, 피부 탄력, 피부 장벽 등)를 확인하기 위한 장기간에 걸친 테스트
  • 실제 사용 기간을 초과한 제품에 대한 집중적인 일회성 테스트, 추후 사용 부위에서의 테스트
  • 반복적인 패치 테스트 – 3-스타 보증 인증마크(3-Star-Guarantee-Seal)의 정확한 인정을 위해, 인증 일자는 인증마크에 표기되며, 테스트 설계에 대한 추가 정보는 웹사이트에서 확인하실 수 있습니다.

Disbalance of the microbiome and skin disease

The natural microbiome prevents pathogens from colonizing the skin, and in circumstances where the balance between commensals and pathogens is disturbed, skin disease or even systemic disease can result. A number of relations between microbiome disturbances and skin diseases are known, while others still await elucidation.

  • It is well known that atopic dermatitis and psoriasis are associated with an imbalanced microbiome, reduced microbiome diversity, and often colonization by Staphylococcus aureus.
  • An increase in Demodex mites, as well as disbalance of Staphylococcus epidermidis has been shown to be involved in rosacea.
  • Overgrowth of Malassezia is involved in dandruff, and altered abundance of Cutibacterium and Staphylococcus also appears to be associated with dandruff.

Why microbiome analysis?

Even though the microbiome is considered relatively stable, the skin is exposed to many internal and external influences that can disrupt the balance of the skin microbiome. These include, for example, stress, diet, age, or weather. Some cosmetics and cleansing products can also affect the microbiome. Therefore, ensuring microbiome-friendly properties of products is becoming increasingly important for both consumers and manufacturers.

For products used to improve dysbiosis, such as atopic dermatitis, a positive effect on the microbiome can be scientifically confirmed.

Products for microbiome analysis

  • Almost all products with regular skin contact may have an impact on the natural microbiome and should be analysed regarding their microbiome-friendliness to maintain diversity and composition of the natural microbiome.
  • Products used to alleviate skin diseases such as psoriasis, rosacea, or atopic dermatitis are particularly suitable to confirm positive effects on the microbiome.
  • Examination of the fungal microflora may be useful in conditions such as seborrheic eczema or dandruff.
  • In particular, the effect on the microbiome should be investigated for pre- and postbiotic products.

How we test the microbiome

In the past, predominantly classical microbiological culture methods were used to characterize the skin microbiome. This method under-reports bacteria that cannot be cultured easily, and molecular biology techniques are now the state of the art.

The 16S rRNA gene is used for microbiome studies because it is overall highly conserved among bacterial species. In addition to highly conserved regions, however, 16S rRNA gene sequences also comprise hypervariable regions that can provide species-specific signature sequences useful for bacterial identification. Similarly, the internal transcribed spacer (ITS) region can be used for taxonomic profiling of fungi.

인증마크(Seal)를 위한 4단계

Support of claims of “microbiome friendliness”

Consumers are attracted to cosmetic products that have been designed and confirmed to leave the natural skin microbiome – and thus its protective functions – intact. Microbiome-friendly products are designed to maintain the normal, healthy composition and function of the microbiome. The product ensures that diversity and composition are preserved during use.

With our microbiome test, we support claims of microbiome friendliness such as: microbiome- friendly, gentle on the microbiome, maintains the natural microbiome, preserves the natural biodiversity of the microbiome.

In cases of dysbiosis, e.g. atopic dermatitis, we can support claims like increases the natural biodiversity of the skin or regulates the microbiome.

Each microbiome test is part of an application study and can be combined with skin measurements to show the efficacy of the product with respect to the consumer the product is intended for.

The inclusion criteria and the product-specific study design are the first milestones to support your claims!

Your route to the seal of approval in 4 steps

You send us your enquiry. We would be delighted to inform you about our available seals, which can be provided. Depending on the test design we plan the corresponding test methods and define the assessment criteria with you. We develop the most suitable study design for your product based on your preferences, ideas and our requirements.

You confirm the suitable study designs or assessments and send us the required sample quantities and information to go with it. We can then start immediately with the internal risk analysis, specific preparations for the study or assessment, and if necessary the recruitment of test subjects.

We carry out the jointly agreed assessment - perhaps an assessment for using the seal “natural ingredients” - at one of our test sites.

If your product has successfully passedour review stage and assessment, we then send you the assessment report and authorisation to use the appropriate Dermatest® seal. Besides the English version, we would be delighted to provide you with the Dermatest® seal to support sales in the national language of your sales markets as appropriate.

자주 묻는 질문

오리지널 더마테스트 인증마크(Seal)는 테스트 방법의 추적, 소비자의 안전과 제조업체의 보증을 나타냅니다. 테스트 디자인과 연구 유형에 따라, 인증마크는 4가지 등급으로 나뉩니다.

No, the products can also contain natural ingredients made from animals such as honey, bee wax or milk.

In general mineral oil-based raw materials are not prohibited in the products, but they do not count as natural ingredients.

Based on the raw material specification of the certificates of analysis, the quality and composition of the raw materials is checked with a further focus on the use of ingredients of natural origin.

No, the seal guarantees the naturalness of the product, it does not guarantee the climate friendliness.

For the “natural ingredients” label, 95% of the ingredients must be of natural origin. For the “derived natural ingredients” label, 95% of the substances must meet these requirements to at least 50%.

Nanomaterials of natural origin are permitted. If they are not of natural origin, they do not count as natural raw materials.

Nanomaterials are materials whose individual units are between one and one hundred nanometres. They can occur naturally, be by-products of combustion reactions or be produced specifically by technology to fulfil a special function. Due to their small size, nanomaterials can have different physical or chemical properties than larger particles of the same material.

Because palm oil is one of the natural ingredients, it is permitted as an ingredient for certification.

Microplastics are present as contaminants in many food and cosmetic products. Since Dermatest does not test for contaminants but for ingredients, contaminants such as microplastics may be present despite the seal.

The “natural ingredients” seal from Dermatest is an independent and objective seal that tests and guarantees the requirements for natural ingredients as defined by ISO 16128-1 and -2.

Yes, all products with a Dermatest seal are free from animal testing.

ISO 16128-1 and -2 describes a standard that sets an international standard in natural cosmetics. It increases transparency for manufacturers of cosmetic products. A distinction is made between natural, derived natural and organic ingredients.

The packaging material must comply with the requirements of the EU Regulation for Consumer Goods, Regulation (EC) 1935/2004 in conjunction with Regulation (EU) 10/2011 (migration of polymer additives) as well as Regulation (EC) 2023/2006 (Good Manufacturing Practice for Food Contact Materials).

The ingredients are tested by food chemists, dermatologists, allergists and/or biologists.

They are permitted, but do not count as natural ingredients.

Genetically modified plants are plants in which the genetic material has been altered in a way that would not be possible naturally through crossing and/or natural recombination. Through genetic modification plants produce for example particularly high amounts of a certain ingredient or they are pesticide-resistant.

Yes, plant-based raw materials of genetically modified plants are permitted, as these also count as natural ingredients.

Dermatest is certified to ISO 9001 by TÜV Rheinland.

No, these seals test for naturalness and not for the farming methods used

Because natural ingredients can also cause allergies, no guarantee of the compatibility of the products can be given despite the seal.

As Dermatest is an independent dermatological institute, all products must meet the “natural ingredients” or “derived natural ingredients” requirements. Greenwashing is therefore not possible.

Greenwashing refers to companies or institutions that present themselves as particularly environmentally aware and environmentally friendly through ecological projects, PR measures, monetary donations or similar activities, without there being any sufficient basis for this.

The brands awarded the seal contribute to the protection of environmental resources and climate protection.

Preservatives are added to products to inhibit growth of microorganisms such as bacteria, fungi or yeasts.

Preservatives of natural origin are permitted. If they are not of natural origin, they do not count as natural raw materials.

The “natural ingredients” seal from Dermatest guarantees that the requirements for a natural product according to ISO 16128-1 or 2 are met.

After all the necessary documents and test material for the product have been received, the epicutaneous test is carried out in the test person centre after the ingredients have been checked. The focus here is on skin compatibility. If the test is successful permission to use the seal is granted and a study report issued.

The “natural ingredients” or “derived natural ingredients” labels enhance brand perception and increase the seriousness or authenticity of the product, which can have a positive impact on sales volume.

After very strict and detailed assessments, the certified manufacturers can place the logo with the “natural ingredients” or “derived natural ingredients” seal on the approved products.

We do not set a time limit for the use of the seals. However, if something changes in the composition and recipe of the products, a new test must be carried out. According to EU law, the period during which the test was carried out must be indicated on the product packaging, which is why the test month and the test year are stored in the seal.
