About Us
Beauty is a matter of responsibility.
Welcome to Kosmetikinstitut Expert
In an industry often driven by quick trends and loud promises, we have chosen a different path: one of substance.
When it comes to your face – your eyebrows, your lips, your skin – there is no room for experiments. Permanent make-up and aesthetic facial treatments are a matter of trust. They require more than just technical skill; they demand a deep understanding of proportions, an uncompromising quality awareness, and the courage to be honest.
That's what we stand for. Since 2013.
🏛️ A foundation that lasts: Our history
When Kosmetikstudio Expert was founded in 2013 in the center of Berlin, the vision was clear: To create a place where craftsmanship stands above hype.
Berlin is fast-paced. But true quality takes time and consistency. What began as a specialized studio has developed over more than a decade into one of the premier addresses for sophisticated pigmentation and skincare in the capital.
We didn't follow the current – we shaped it.
Our existence over this long period is no coincidence, but the result of consistent work towards perfection.
Olga Keller
Pioneering spirit meets state-certified expertise
Behind the quality of Kosmetikstudio Expert stands Olga Keller. She is not just the owner, she is the soul and benchmark of every treatment.
As a state-certified cosmetician, she possesses a medical and dermatological foundation that has become rare in today's "quick-beauty" world.
This routine cannot be replaced – it is the difference between a "good" and a perfect, natural result.

📜 Expertise you can see – and feel
A certificate on the wall is quickly hung. For us, however, continuing education means something different: It is the respect for you and your trust.
The number of diplomas and certificates that Olga Keller has acquired over the years would literally barely fit on a single wall. But we don't display them to impress. We use this knowledge to ensure that every step is precise.
Whether the latest techniques in pigmentation or advanced methods of skin improvement like microneedling and cold plasma – we are constantly learning so that you can relax.
We don't work on an assembly line. We work on your self-confidence.
💎 Our Philosophy: Results over revenue
Our consultation is different. It is honest.
We believe that the best treatment is always the one that suits you – your facial architecture, your skin type, and your lifestyle. This also means that we decline a treatment if we are convinced that it will not achieve the desired, harmonious result.
We only offer what has been proven to work and is safe.
No cookie-cutter approach. Every face is unique and is treated as such.
Our goal is not for people to see that something was done, but for you to simply look better.
🌍 Trust that knows no boundaries
Quality spreads by word of mouth – often far beyond the city limits of Berlin. We are proud that clients regularly travel not only from other German cities, but also from abroad, to be treated exclusively by Olga Keller.
Our regular clientele also includes numerous well-known personalities and decision-makers from politics. They all appreciate not only the uncompromisingly natural result, but above all one thing: our absolute discretion and anonymity.
Those in the spotlight don't leave their face to chance – and that's exactly why they trust us.
With us, your beauty is a private matter.
🛡️ Quality you can touch
Trust is based on transparency. That's why we make no secret of what we work with and how we calculate.
Safety through "Made in Germany"
Pigments: We work exclusively with certified pigments of German manufacture. They are free of heavy metals (such as nickel), iron oxide-free, and dermatologically tested. This guarantees not only the highest compatibility, but also color stability – so that your eyebrows don't turn reddish or bluish even after years.
CNC Cosmetic Active Ingredient Cosmetics
Care: For our apparatus-based facial treatments, we rely on the medically-based active ingredient cosmetics from CNC Cosmetic. We use these products because they deliver visible results and are subject to the strictest quality controls.
Your retreat in Berlin-Mitte
Our studio is centrally located on Heinrich-Heine-Straße, in close proximity to Alexanderplatz. We have deliberately created a place that is easily accessible to you, but offers an oasis of calm inside.
Out here, the city noise stays behind – inside, only your relaxation matters.
Honest prices for honest craftsmanship
Premium to us doesn't mean "overpriced", but "worth its price".
Our pricing is fair, transparent, and loyal. You pay for years of expertise, hygienic safety at clinical level, and high-quality materials. There are no hidden costs with us – you invest in a result that brings you joy every day.
