Frequently asked questions


What is a gene?

Our DNA is composed of a sequence of nucleotides, or repeating units comprised of three basic components: a phosphate group, a pentose sugar (deoxyribose) and a nitrogenous base. Nitrogenous bases are the variable components of the DNA: they are Adenine, Guanine, Cytosine and Thymine and they repeat randomly through the polynucleotide chain. A gene then is a long sequence of DNA containing the informations needed to the development of an individual coded with a triplets code based on the four bases sequence. The genes set constitute each living being genetic heritage.

What is the genome?

The totality of all the genetic information inside the nucleus of our cells

What is a chromosome?

The DNA inside the nucleus is organized in complex three dimensional structures called chromosomes. Man has 46 chromosomes organized into 23 pairs, of which the last one determines an individual sex. The totality of the chromosomes forms the karyotype

What is an SNP?

An SNP (Single karyotype polymorphism or, simply, polymorphism) is a change at the level of a single nitrogenous base of the DNA. About 99,9% of human genome is identical in all individuals, the remainig 0,1% is what differentiates between each other. Most of this variability is caused specifically by the presence of polymorphisms in the DNA. Polymorphisms can influence an organism response to specific environmental conditions and be an indication to predict each individual risk to develop a specific disorder. For example they can influence specific sugars methabolism (lactose, glucose) leading to the tendency to develop food intolerances; change the defense mechanisms against free radicals and oxidative stress; lead to collagen degradation and alter cutaneous elasticity causing premature wrinkles formation, other can lead to the development of specific illness as obesity or cardiovascular pathologies. Therefore knowing single bases alterations is important to predict the risk of developing specific pathologies.


What kind of test is "beauty" by netgenomics?

The beauty genetic test is a non-invasive dna analisys that examines the skin susceptibility to toxic agents, uv rays and inflammation. the test will assess the genetic sensitivity of your skin to those factors that accelerate the aging process. the test results are included in a report that describes the 3 different predisposition levels (high, medium and low).

Where can i buy it and how much does it cost?

The test will be initially available in selected pharmacies for a price of € 265 euros for further information please contact our customer service on 02 4003 1404.

What is the purpouse of the "beauty" genetic test?

We recommend the beauty dna test to customers who wish or need to know the genetic susceptibility of their skin to environmental factors and seek to implement personalized prevention measures based on their genetic profile such as:

  • understand what food is best to avoid to minimize metabolic stress;
  • control their exposure to sunlight;
  • start a preventive care for their skin health;
  • assess their predisposition to the development of melanoma and prevent it.

Are there any other genetic tests available?

Coming soon: a nutrition dna test (to offer advice on dedicated diet programme, food intolerances and needs based on your genetic profile) and a performance test (to help you improve your physical performance and choose the most suitable sport based on your genetic profile ). many others will follow in the future.


How do i do the test?

The explanatory video tutorial is available on our homepage. In addition, the brochure included in the kit explains in details the entire process, from collection to delivery of the test. For further information you can contact our customer service on 02 4003 1404.

What kind of sample does the test require?

A sample of saliva, to be collected with the two buccal swabs included in the kit. Simply rub them on the inside of your cheeks, upper and lower lips and under the tongue for a minimum of 30 seconds. allow the pad to air dry for a few seconds and place it in its test tube.

Why does the kit contain two swabs?

To ensure that the analysis is carried out correctly

Once i collect the sample, how do i store it and how long can be kept before it is delivered?

The sample should be stored in a dry environment, at room temperature (5°c - 25°c), away from heat sources, direct sunlight and open flames. It is recommended to ship the sample or deliver it to your trusted advisor within 4 days of collection

What happens if one or both swabs get damaged?

Please contact our customer service on 02 4003 1404 and state your kit code (placed on the adhesive labels on the qrcode card).

How is the sample sent to the laboratory after collection?

Delivering the sample is quick and easy and you can choose between two different delivery methods:

  1. after registering on the site or using the qrcode found on the sticker and typing the kit identification code, you can book the courier on the website under "easy collection" ( with your selected date and time.
  2. you can deliver the envelope containing the pads and the informed consent sheet to your trusted advisor.

Is the shipping procedure safe?

The shipping procedure is followed and tracked by our customer care so there is no margin of error

How is the dna in the swab analyzed?

The dna is extracted from the mouth wall epithelial cells that ar trapped in the swab. Once extracted it is analyzed with next generation sequencing machines. Next generation sequencing techniques are sequencing methods that enable to identify the exact bases sequence composing the dna. Said techniques enable the parallel sequencing of a great number of samples, speed and greater accuracy in data processing than the previous techniques.


How is the analysis done?

Your dna extracted from the saliva sample is sequenced with innovative illumina sequencing instrumentation. The data obtained are then analyzed using artificial intelligence techniques. The analysis is carried out in our laboratory in italy.

What does the test analyse?

The test examines 52 genetic variants or snps present in genes associated with different aspects of skin physiology and the whole sequence of 2 genes related to melanoma predisposition.

How long does it take and how do i receive the results?

Within 3-4 weeks from receipt of the sample in our laboratory you will be contacted by email and instructed to access your reserved area, where you can download your report in pdf format.

How reliable are the results?

The results produced have an accuracy rate higher than 99%.


Are there any contraindications?


Is the test recommended to everyone? are there any restrictions?

The test is suitable to everyone but has no diagnostic purposes


How are my personal data processed?

Our certified laboratories in italy operate following high safety standard procedures. We treat your personal data in accordance with the principles of privacy, correctness, lawfulness and transparency established by art. 13 of the eu regulation 2016/679. Any personal information will be processed for the sole and exclusive purpose of performing the dna test correctly. Your biological samples and genetic data are subjected to encryption techniques that ensure the highest levels of security and anonymity; they are stored in protected premises and managed by authorized personnel only

Can I send someone else's dna sample without them knowing?

No, it is illegal to treat someone else's dna without permission. The informed consent contains mandatory data and requires the handwritten signature of the person performing the test
