Doctor Mi!
"Our skin is not just a protective barrier – it's a dynamic, living organ that stays with us throughout our entire lives."
In this interview, Dr. Rehbein shares the brand's philosophy, her favorite products, professional insights, and the challenges of modern skincare innovation.
The Philosophy
What was your vision for DOCTOR MI!?
"To create skincare products that not only rely on scientific findings but are also tailored to the individual needs of every client in my practice. I wanted to build a brand known for both exceptional effectiveness and gentle tolerability. My goal was to develop products that genuinely help clients—designed to nourish and enhance various skin types so everyone can feel comfortable and beautiful in their skin."
What sets DOCTOR MI! apart from other anti-aging brands?
"DOCTOR MI! combines dermatological expertise with personalized skincare solutions. With years of experience, I know what truly matters for effective skincare. Our products use high-quality, scientifically proven ingredients and advanced technologies like TECMi!® Deep Technology, offering skincare that is both powerful and gentle, even for sensitive skin."
Which scientific principles are most important to you in product development?
"The skin is a complex organ, which is why we focus on the synergy of highly concentrated active ingredients. Our formulations are designed to support cellular processes, strengthen the skin barrier, and boost the skin's natural regeneration."
Focus: Anti-Aging
What are the biggest myths surrounding anti-aging and skincare?
"One common myth is that anti-aging products provide immediate results. Effective skincare requires consistency and patience. Moreover, UV protection and proper hydration are often overlooked, yet they are the foundation of any anti-aging routine."
Which ingredients are most effective in combating skin aging?
"Retinol and vitamin C are two of the most powerful ingredients. Retinol promotes cell renewal and boosts collagen production, while vitamin C neutralizes free radicals as an antioxidant and brightens the complexion. Hyaluronic acid is also essential for providing hydration and plumping the skin."
About Routines and More
What does a daily skincare routine for maintaining youthful skin look like?
"An ideal routine includes at least three steps: cleansing, protection, and regeneration. In the morning, I recommend gentle cleansing, an antioxidant serum, a moisturizer, and sunscreen. In the evening, cleanse thoroughly and apply regenerative ingredients like retinol and peptides."
What habits accelerate skin aging?
"Major risk factors include UV exposure, smoking, and chronic stress. Insufficient skincare, poor diet, and lack of sleep also significantly speed up the aging process."
How can someone determine the right routine for their skin?
"The key is to understand your skin's needs. A professional skin analysis can help identify the right products. Pay attention to how your skin responds—it often gives clues about what it requires."
What does your personal skincare routine look like?
"In summer, I opt for lighter textures, antioxidants, and high SPF. In winter, I prioritize intensive hydration and barrier protection to guard my skin against the cold and dry indoor air. Retinol remains a year-round essential in my routine."
Science, Innovation, and the Future
How important are scientific studies and research in your product development?
"Our products are based on scientifically sound findings, with effectiveness and tolerability as our top priorities. We integrate the latest research with cutting-edge technology to ensure that our formulations are both effective and tailored to individual skin needs."
What new technologies or trends in anti-aging excite you?
"AI is playing an increasingly significant role, especially in personalized skincare. Algorithms can analyze skin needs and provide tailored product recommendations. Micro-needling and biomimetic ingredients are also exciting areas of innovation."
What challenges do you face in formulating highly effective products?
"The greatest challenge is finding the balance between effectiveness and skin compatibility. High concentrations of active ingredients can cause irritation, so it's essential to formulate them for maximum effectiveness while being gentle on the skin."
Now It Gets Personal!
What is your favorite product and why?
"My favorite is SUPER RED, our Overnight Refining Treatment. It combines highly concentrated, encapsulated retinol with our unique TECMi!® Deep Technology, delivering deep-acting results overnight. It leaves the skin smooth, radiant, and even-toned; it's suitable even for the most sensitive and rosacea-prone skin. A true power product!"
How do you define "beautiful skin," and how can it be maintained long-term?
"Beautiful skin is healthy, even, and radiant. To maintain it long-term, consistent care is essential, along with a healthy lifestyle and protection from external factors like UV radiation."
Do you automatically notice people’s skin conditions when you meet them?
"Of course, I notice skin right away because it reveals so much about a person’s overall health. However, I don’t judge it critically—I see it as a reflection of personal habits and lifestyle."
What does "skin health" mean to you beyond the anti-aging aspect?
"Skin health means an intact barrier, well-hydrated complexion, and the absence of inflammation or irritation. It’s about supporting the skin’s natural balance."
Looking Ahead
What can we expect from DOCTOR MI! in the future?
"We are continuously working on innovative, high-performance formulations and enhancing the personalization of our products. This fall we'll also be introducing a completely new product line. Looking ahead to 2026, we plan to relaunch our existing products with fresh designs and improved concepts—focusing on true innovation rather than chasing every trend."
How do you see the skincare industry evolving over the next decade?
"The skincare industry will become more personalized and technology-driven. Consumers increasingly demand tailored products that meet their specific skin needs. Sustainability and science will play a crucial role."
What is your key message for those investing in skincare?
"Our skin is more than just an outer layer—it’s a living organ that accompanies us throughout our lives. Investing in its health pays off in the long run. Quality, consistency, and proper protection are key to beautiful, healthy skin. Sometimes, it’s the small daily choices that make the biggest difference in helping us feel comfortable in our skin."
