PRETORIA, South Africa – In a landmark move for the local beauty and wellness industry, Pretoria-based medical professional, Dr Juanri Jonck and Somatologist Bernadette Kruger, have officially launched Twenty 4, the country’s first serum-led, medical-grade skincare range produced locally. The launch introduces a new philosophy to the South African market: moving beyond superficial moisturizing to targeted, cellular-level correction with proudly local, scientifically formulated serums.
By Dr Juanri Jonck & Bernadette Kruger, Co-Founders of Twenty 4
As an aesthetic doctor, Dr Juanri Jonck has spent years observing a gap between expensive clinical treatments and the over-the-counter products promising results they rarely deliver. “For years, we had to convince patients to pay premium prices for the best formulations, which often meant they could only afford one serum at a time,” Dr Jonck explains. “We know that combination therapy is key. Bernadette and I decided to formulate the key ingredients with the most clinical evidence and make them available to our patients at an accessible price point. Beautiful skin should not be limited to those with a beautiful budget.”
Twenty 4 disrupts the traditional skincare model by placing serums at the forefront of every regimen – the true powerhouse of any effective routine. Unlike heavy creams that primarily manage the skin’s surface, serums are engineered with low-viscosity, high-concentration active molecules designed to penetrate deeper layers for real, visible change.
The range is built on the medical principle of “coaching” the skin rather than creating dependency. Dr Jonck warns against the “lazy skin” trap, where occlusive products cause the skin’s natural renewal processes to slow down. Twenty 4 serums work in synergy with the skin’s biology, utilizing evidence-based actives to encourage healthy turnover and collagen synthesis from within.
Key highlights of the Twenty 4 launch include:
- First-to-Market Innovation: Twenty 4 is the inaugural serum-led, medical-grade skincare range available in South Africa.
- Proudly Local Production: Formulated and produced in South Africa, the range combines international scientific standards with local expertise.
- Medical-Grade Potency: The formulations utilize pharmaceutical-grade actives at evidence-based concentrations, stabilized for maximum efficacy.
- Empowerment Through Science: The brand focuses on “effective skincare routines” that empower the skin to function optimally, avoiding ingredients that impair intercellular communication.
- Accessible Efficacy: By stripping away unnecessary “filler” ingredients and marketing markups, Twenty 4 makes combination therapy—using multiple targeted serums—financially viable for the average consumer.
“When it comes to ingredients, we look for proven performers: Vitamin C as a collagen co-factor, Retinol as the gold standard for anti-ageing, and Niacinamide to strengthen the barrier and calm inflammation,” says Dr Jonck. “But a one-size-fits-all approach fails. The clinical advantage of Twenty 4 is that these aren’t just products on a shelf; they are part of a scientifically-backed strategy for skin health.”
Dr Jonck emphasises that the most potent serum is rendered useless without daily, broad-spectrum SPF, reinforcing that true skincare is a commitment to science, not just cosmetics.
The Twenty 4 range is now available to the South African public, offering a new paradigm in skincare: medical expertise, local pride, and clinical results without compromise.

The rarest of all things in American life is charm. We spend billions every year manufacturing fake charm that goes under the heading of Public Relations. Without it, America would be grim indeed. – Anita Loos

It doesn\’t matter what word we use, if it has the same content, it will be treated in the same way. There are other words – there\’s \”womanist,\” there\’s \”mujerista,\” there\’s \”women\’s liberationist\” – all mean the same thing and they get the same ridicule. I think we just need to choose what word we feel comfortable with that says women are full human beings, and whatever that word is, it will get a lot of opposition. But it will also attract a lot of support. But this is a revolution, not a Public Relations movement. – Gloria Steinem

When Bernays first started writing about Public Relations, he referred to it as an ‘applied social science’. At the time (around 1920), the concept of social psychology was gaining popularity. And, thanks to his double uncle, the public was starting to accept the idea of psychology more and more. Bernays viewed PR as a way of understanding the attitudes and behaviors of crowds and how to change them. Back then, communication was just one of the ways to achieve that.
