The emerge of House of Bratz

House of Bratz is a young cosmetic clinic for injectables and skincare, founded two years ago by Souhayla. Souhayla born in North-Brabant started, at the age of nineteen, with her own beauty salon. Once a month she offered her clients injectable treatments by a cosmetic doctor. Because of Souhayla’s innovative ideas and excellent marketing skills the treatments became a great succes. After a while she decided to make her dream come true and start House of Bratz. She became the figurehead of House of Bratz and ambassador for cosmetic treatments.

In the past two years House of Bratz has grown exponentially and became one of the most known clinics in the Netherlands. House of Bratz receives more than 150 clients a week from all over the country, but also from Belgium, Germany, Luxembourg and even France. Among these clients are numerous VIP’s.

The secret of House of Bratz lies within our passion for the art of cosmetic medicine. Our staff is skilled and extremely motivated to improve every day.

Course instructor

Drs. Coriene J.L.M. Catsman (1989) graduated from the Erasmus Medical University in Rotterdam in 2014. During her study period she was already interested in plastic and cosmetic medicine and after internships in (plastic and reconstructive) surgery she decided
to work at the surgery department, ER and ICU to expand her skills as a clinical doctor. Although the complicated and interesting hospital patients gave here an amazing clinical foundation she missed the personal connection with patients and had the feeling
she couldn’t provide the patients what they desired.

In 2017 Coriene decided to change course and pursue a combined career in both cosmetic medicine and general practice. This gives her the opportunity to provide personalised general and aesthetic care and build a long lasting, trustworthy relation with her patients.

The Art of Bratz

Coriene joined team Bratz in April 2018 and mastered/codeveloped “The Art of Bratz” by listening to the wishes and beauty desires of her clients. The Art of Bratz does not contain one signature look as the perfect look is different for every client. Our method is based on client wishes and desires, facial proportions and of course “Divina Proportione”, the golden ratio. The golden ratio is not new, it has already been used for centuries in art, architecture and mathematics by grandmasters such as Davinci, Fibonnaci and Dalí. Consciously playing with the golden ratio and facial proportions to create a desired classic/natural look or a fashion sensitive fierce look is new. For every desired look and unique client facial features we have a preferred (combination of) technique(s) to create the perfect look.


Everybody can be an injector, it is like the hundredth monkey effect, but only the ones passionate about a clients beauty desires, facial proportions, perfection and imperfections can master the art of creating beauty, “The Art of Bratz”.
