We sit down with Dr. Marko Lens, founder of Zelens, to explore the fascinating journey that bridges his childhood passion for botanicals with his pioneering work in science and skincare formulation.

Dr. Lens dives into Zelens’ hybrid approach, which strategically balances high-tech actives with natural extracts, while also shedding light on why topical Vitamin D is crucial for skin health and barrier repair. Read the conversation now!

    Can you share a bit about your journey and what inspired your work in science and skincare formulation?

    My lifelong passion for botanicals and formulations began at a young age, under the instruction of my grandmother, who would create her own bespoke skincare remedies with oils and plant extracts.

    I was absolutely fascinated with the world of plants. This interest deepened when I was given a two-volume encyclopaedia of herbs which I committed to memory. This treasured possession inspired a childhood of alchemical experiment and sparked lifelong passion for nature’s botanicals. While my passion for skincare and product formulation was ignited as a child, it was while studying for my PhD in Oxford that I cemented my professional interest in science and skincare. It was here that I came to understand how skin cancer and skin ageing share a common pathway.

    While researching the role of topical antioxidants in skin cancer, I explored whether topically applied antioxidants could slow down premature skin ageing. This realisation served to become the first step in a career of research, product formulation, and in-clinic treatments that straddle the distance between pharmaceutical and cosmetic.

    Known for combining biotechnology with botanicals, how do you ensure this balance in your formulations, and what benefits does it offer?

    We are a hybrid skincare brand, which means we combine high-tech ingredients with botanicals. Our formulas always contain multiple ingredients that work together in synergy. The balance of ingredients is essential, and only multiple testing can lead to the final formulations with a well-balanced combination of high-tech active ingredients and botanicals.

    Why is Vitamin D a crucial ingredient in skincare, and how does it benefit the skin beyond its role in bone health?

    Vitamin D is a very important element because it protects the immune system of the skin, offers antimicrobial protection, and helps repair the barrier function. Also, latest research showed that Vitamin D promotes keratinocyte (type of skin cell) proliferation, which is very important in the skin renewal process.

    Many are aware of sun exposure as a source of Vitamin D. How does topical application compare in effectiveness and safety?

    Zelens was a pioneer in the use of provitamin D3 in skincare in early 2014. Topical application of vitamin D helps repair the skin barrier and protects the skin from environmental factors while supporting the normal skin renewal process. We did extensive studies showing the important topical role of provitamin D3. One of the “must-haves” in skincare should be Zelens Power D. The beauty of this product is not only the performance but the fact that you can add a few drops of it to any skincare regime you are using and do not want to interrupt.

    Could you tell us a little about Zelens’ Vitamin D formulas and how they deliver effectively?

    Power D contains a high amount of provitamin D3 in an ester-based formulation. We are using liposomes as the delivery system to help the delivery of provitamin D3. In Provitamin D3 Fortifying Mist and Emulsion D, we are using vitamin D encapsulated in cyclodextrins, which are helping with the delivery of vitamin D. So, as you can see, it is a rather pharmaceutical approach in the delivery of provitamin D3 for topical, cosmetic use. I am very proud of our technology.

    What makes Power D different from Emulsion D in terms of formulation and skin benefits?

    Power D is a concentrated serum containing a high amount of provitamin D3. Also, it contains natural provitamin D3 sources from mushrooms and lichen. It is an ester-based formulation that provides instant moisture and replenished lipids, which are crucial in the repair of the barrier. Emulsion D is an essential moisturiser that contains a significantly lower amount of provitamin D but is still important to promote skin renewal and help protect the skin while providing moisture.
