Same trusted formulas. One bold new identity. Résa·K Skin Science
(formerly Biodermal Skin Tech)
Résa·K Skin Science represents the next evolution of a trusted South African cosmeceutical brand, formerly known as Biodermal Skin Tech. While our name and identity have evolved, our commitment to science-led skincare, uncompromised formulations, and visible results remains unchanged. Founded in 2014, our journey began with a vision to create affordable, professional-grade cosmeceutical skincare that delivers corrective and preventative results across a wide range of skin concerns — including ageing, acne, pigmentation, dehydration, and uneven skin tone. Led by CEO ,Founder and formulator Dr Résa Kahn, a biomedical scientist with over 24 years’ experience in the pharmaceutical and aesthetic industry, the brand is driven by deep scientific expertise and relentless innovation. Résa works closely with renowned Professor Aubrey Parsons and a dedicated research and development team of pharmacists and specialists to formulate advanced skincare solutions that meet international standards. Our formulations combine cutting-edge cosmeceutical technology with high-performance active and natural ingredients, carefully developed to suit the South African climate, which can be particularly harsh on the skin. All products are proudly manufactured in South Africa, cruelty-free, and never tested on animals. Résa·K Skin Science continues the Biodermal Skin Tech legacy — refined, elevated, and future-focused. Same trusted science. One vision.

Considering cosmetic surgery? Plan for your skin’s recovery before the procedure.
We often spend months researching the surgeon, the procedure and the result we want — but what happens to the skin afterwards deserves just as much consideration.
Résa.K Corrective Scar Complex is an advanced topical treatment formulated to support compromised skin and help visibly improve the appearance of scars as the skin repairs and remodels.
With peptides, Centella Asiatica, niacinamide, squalane and AHAs, the formula helps support the skin barrier, maintain hydration and improve the appearance, texture and flexibility of scar tissue over time.
Whether you’re preparing for a facelift, breast surgery, abdominoplasty or another cosmetic procedure, make your scar-care plan part of your recovery conversation.
Considering cosmetic surgery? Corrective Scar Complex should be your next considered purchase.
Always follow your surgeon or medical professional’s instructions regarding when topical scar care can safely begin.

Professional strength. Targeted results. 🔬
No two skins have exactly the same needs — and professional treatment shouldn’t be one-size-fits-all.
The Résa.K Professional Derma Concentrates allow trained skincare professionals to target specific concerns with advanced actives selected according to the skin in front of them:
✨ Derma-Bright — targets uneven tone and supports a brighter-looking complexion
✨ Derma-Tite — peptide-powered support for firmness, elasticity and skin renewal
✨ Derma-H.A.C — intensive hydration and regenerative support for skin that needs restoring
Used within a professional Résa.K treatment protocol, each concentrate allows for a more considered, targeted approach to achieving visible results.
Professional expertise. Intelligent skin science. Personalised care.

One ingredient. Almost every formula. There’s a reason. 🔬
Meet Niacinamide (Vitamin B3) — one of skincare’s most versatile and well-tolerated actives, and a key ingredient across the Résa.K range.
Niacinamide helps to support multiple aspects of healthier-looking skin:
✨ Strengthens and supports the skin barrier
✨ Helps balance excess oil
✨ Refines the appearance of pores
✨ Supports a more even-looking skin tone
✨ Helps soften the appearance of fine lines
✨ Supports overall skin resilience
And because it works beautifully alongside other targeted actives, Niacinamide isn’t treated as a standalone hero at Résa.K. It becomes part of an intelligently formulated regimen, where ingredients work together according to what your skin needs.
One ingredient. Multiple benefits. Smarter skin science.

Skin renewal should be intelligent, not aggressive. ✨
When dullness, uneven texture and visible signs of ageing begin to affect the way your skin looks and feels, sometimes your everyday routine needs the support of a professional treatment.
Résa.K Renu Peel is a professional resurfacing treatment designed to encourage controlled skin renewal — helping to refine the appearance of texture, restore luminosity and reveal a smoother, fresher-looking complexion.
The difference is in the approach: professional peeling isn’t about stripping the skin. It’s about selecting the right peel, at the right strength, for the right skin.
That’s why Renu Peel forms part of the Résa.K professional treatment offering and should be performed by a trained skincare professional, with appropriate homecare supporting the skin before and after treatment.
Renew. Refine. Reveal healthier-looking skin.

What is your skin trying to tell you? 👀
Tightness, dullness, congestion or fine lines aren’t just things to cover up — they can be signs that your skin needs a different kind of support.
💧 Tight & flaky? Think barrier support + hydration.
✨ Dull & uneven? Focus on cell renewal + tone.
🔬 Congested & shiny? Support healthy oil balance without stripping.
🤍 Fine lines & loss of firmness? Look to peptides + targeted renewal.
The key is not adding more products. It’s choosing the right products for what your skin actually needs.
That’s why Résa.K Skin Science takes an intelligent, skin-first approach to building a regimen — supporting hydration, barrier function, inflammation control and renewal for healthier-looking skin over time.
Which one sounds most like your skin right now?
