The customer is wearing make-up. Can I perform the analysis regardless?

The customers normally have already care products or even make-up or powder applied when they enter a shop. On make-up and powder it is very difficult to take measurements or camera images. If you kopfcleanse the skin, however, it may take up to 2 hours for the skin to regenerate the normal conditions (especially of sebum) completely. Therefore ideally you would perform the measurement on skin cleansed two hours prior to the measurement, but this is practically impossible.

We recommend therefore dabbing the skin with a dry cosmetic tissue at parts where you would like to measure or take images. Remove make-up from the skin but without rubbing. Do not rub, because that would take away the sebum and enhance the micro circulation. Should this not be possible, switch to un-treated skin areas (close to the hair and the ears and under the chin or for melanin content on hands and arms). Relativize, especially with high temperature and high air humidity. In any case you are only taking the momentarily state of the skin with measurements at the point of sale.

The customer has bought a very exclusive product but she/he returns after using it, the measurement results have not improved (worst case: they have worsened).

Skin is a living organ and reacting to several internal and external influences (e.g. state of general health, sleeping habits, diet, stress, alcohol and nicotine consumption, season, climate and many more). There is a variety of reasons for worse measurement results.

It is also possible that the customer is using a very nice skin care product but at the same time aggressive cleansing. Point out that it is important to have a line of products which is aligned to each other.

Make clear that at the POS with so many influences you only determine the current need of the skin.

How can I learn more about the skin?

Buch FloWe can strongly recommend this book "Advanced Skin Analysis" by Florence Barett-Hill a most professional Beauty therapist from New Zealand. It is the book for the skin treatment therapist of the new millennium, taking estheticians on a journey of discovery and revision of their chosen profession.

With a complete update of the anatomy & physiology of the skin, Advanced Skin Analysis shares the relevant discoveries about the skin over the past decade and presents them in an easy to understand, informative manner that links structure and function to various skin conditions.

What is the general difference between devices for the skin type analysis and cosmetic recommendation and the scientific laboratory devices?

The devices for the skin type analysis derive from the scientific measurement methods known for many years and used all over the world for clinical studies and efficacy testing. However, the skin type analysis devices have a less accurate resolution, where they express the sebum content e.g. in "dry", "normal", "oily", the scientific Sebumeter® shows the sebum content in a high precision figure to monitor even smallest changes in the sebum level. The scientific devices possess check calibration tools and facilities and software to support the statistical gathering of data. The skin type analysis instruments are not recommended to use for clinical studies but to increase the sales of cosmetic products and promote certain treatments to the customer.

Which melanin level is normal?

The melanin level is very different from person to person and strongly depending on the ethnical group and the pre-tanning. The measurement is helpful to recommend sunscreen or to compare measurements e.g. before and after a treatment.
