It’s easy to compare Vitamin A serums by looking at the ingredient list, known as the INCI list. It can show you which ingredients are present and, broadly, where they sit within the formula. But it doesn't always show what makes one formula meaningfully different from another.
It doesn't tell you how sophisticated the formula is. It doesn't tell you how well a retinoid has been protected against instability, how it’s delivered into the skin, or which supporting ingredients help make it perform at its best.
That is why we think Total Repair DNA Serum deserves a closer look, because it’s not your ordinary Vitamin A serum.
Let's start with the retinoid. Total Repair DNA Serum contains retinal (retinaldehyde), one of the most advanced forms of Vitamin A used in skincare. You may already know that a Vitamin A serum is one of the most important things you can do for your skin, but what you might not know is why retinal takes your retinoid game up a level.
Retinal is at the centre of the formula, but it isn't the only reason this serum stands apart.
This is a multi-technology night treatment that brings together encapsulated retinal, Juveleven™, vegan Epidermal Growth Factors, antioxidant defence and hydration support in one carefully considered formula.
This is what makes Total Repair DNA Serum one of the most sophisticated formulas in the Aesthetics Rx® range. What sets it apart isn't just what's in the bottle. It's how the formula has been created, how the retinal is delivered, and how the supporting ingredients help the skin look smoother, firmer, more refined and visibly radiant.
Why the retinal delivery system matters
Retinal is one of the most exciting forms of Vitamin A used in skincare because it sits one conversion step away from retinoic acid, the active form the skin can use.
Retinol, one of the most widely used forms of Vitamin A, must first convert to retinal, which then converts to retinoic acid. Retinal places us one step closer to the form recognised by the skin, which is one of the reasons it is so highly regarded in advanced skincare. But with retinal, the challenge is not only choosing the ingredient. It's keeping it stable, protecting it within the formula and ensuring it is delivered effectively.
Like all retinoids, retinal is sensitive to light, oxygen and formulation conditions, which means the delivery system matters. In Total Repair DNA Serum, the retinal is encapsulated to help protect the active, so it doesn't easily degrade within the formula.
Once applied, that same delivery system supports the gradual, controlled release of retinal into the skin.
This is important because a high-performance Vitamin A serum should not be measured by how reactive it feels on your skin. Instead, true performance comes from how the active is stabilised, delivered and supported within the formula. The aim is to deliver visible renewal benefits while supporting a more comfortable experience for the skin.
For Total Repair DNA Serum, the advanced retinal delivery technology is a key part of what makes the formula so sophisticated. It isn't just retinal on an ingredient list. It’s retinal stabilised, protected and delivered in a way that supports visible results with a more considered approach to skin comfort.
This encapsulated retinal technology also has the clinical results to support its performance.
In a clinically controlled study, 30 women aged 35 to 60 used a gel formulated with 5% of the encapsulated retinal material over 56 days. Results showed up to a 67% improvement in firmness, up to a 69% improvement in elasticity and an 18% reduction in wrinkles. Every participant showed a measurable improvement in firmness, with no adverse effects recorded across the study group.
With results like these, the appeal of the encapsulated retinal technology is undeniable. Retinal drives the formula's visible renewal benefits, while its broader repair focus is where two hero ingredients, Juveleven™ and Epidermal Growth Factors come in.
How Juveleven™ supports the skin's natural repair pathways
Juveleven™, is a biomimetic peptide known on the ingredient list as Acetyl Hexapeptide-51 Amide.
Peptides are often spoken about in skincare as firming or smoothing ingredients, but not all peptides work in the same way. Juveleven™ has been developed to support the skin's natural response to stress and the visible effects of environmental ageing.
Every day, skin is exposed to factors such as UV light, pollution and oxidative stress. Over time, these stressors can contribute to visible changes in the skin, including uneven tone, loss of radiance, roughness and the appearance of fine lines.
Juveleven™ helps support the skin's own repair pathways, including the processes involved in responding to environmental stress. This makes it a clever partner for retinal, because while retinal supports visible renewal, Juveleven™ helps reinforce the broader repair-focused purpose of the formula.
In Total Repair DNA Serum, this peptide is part of what takes the product beyond a traditional Vitamin A serum. It helps shift the formula from a single-active approach into something more complete: a night treatment designed to support renewal, resilience and the look of healthier skin over time.
What are vegan Epidermal Growth Factors?
This is where the formula's biotechnology credentials really shine.
Total Repair DNA Serum contains vegan Epidermal Growth Factors, also known in this formula as Bio-Placenta.
Despite the name, Bio-Placenta does not contain human or animal placenta. It’s a biotechnology-derived active created through a controlled fermentation process, making it a vegan ingredient designed for advanced skin support.
Growth factors are naturally occurring proteins that help cells communicate. In skincare, Epidermal Growth Factors are used to support the appearance of smoother, firmer and more resilient skin, particularly when the skin is showing visible signs of environmental ageing or fatigue.
The vegan growth factor complex used in Total Repair DNA Serum contains five different growth factors, including EGF, IGF-1, acidic FGF, basic FGF and VEGF, along with amino acids and vitamins.
Yes, we know, that's a lot of letters, but stay with us. What matters is that these growth factors help support the skin's communication and renewal processes, adding to the formula's overnight recovery focus and helping skin look more refreshed, replenished and visibly renewed.
Vegan Epidermal Growth Factors add another layer to the formula by supporting the look of skin regeneration, firmness and smoothness.
For a night serum, that combination matters. Overnight is when the skin is naturally focused on repair and recovery, so Total Repair DNA Serum has been built to support that rhythm with a more complete, multi-pathway approach.
Why hydration and antioxidant support matter in a retinal serum
While the active ingredients in Total Repair DNA Serum give it hero status, this unique formula is made even better by the ingredients that support it. Together, they create a high-performance night serum designed to support visible renewal, comfort and skin resilience.
Among those supporting ingredients are hyaluronic acid, sea buckthorn oil, Lipochroman™* and microalgae.
Hyaluronic acid helps attract and hold water in the skin, supporting a smoother, more supple appearance. In Total Repair DNA Serum, both high and low molecular weight forms are used to support immediate and longer-lasting hydration.
Sea buckthorn oil brings nourishing fatty acids and antioxidant support, helping to condition the skin and support comfort within the formula.
Lipochroman™ is a powerful antioxidant molecule used to help defend against the visible effects of pollution and oxidative stress. This matters because environmental stress doesn’t only affect the skin during the day. Supporting the skin overnight helps reinforce the formula's broader repair and recovery focus.
Microalgae and polysaccharide ingredients add another layer, helping to support the appearance of tighter, firmer and smoother-looking skin.
Together, these ingredients support hydration, comfort, antioxidant defence and visible firmness, helping keep the skin calm, balanced and protected while the hero active ingredients get to work.

When you're ready for more from your Vitamin A serum
If you've been using the same Vitamin A serum for a while, changing to something different can feel like a big step. We all tend to stick with what we know, particularly when a product has become a familiar part of our routine. So, switching should feel worthwhile.
Total Repair DNA Serum is an excellent choice when you're ready for more from your Vitamin A routine. It's designed to deliver visible renewal for a smoother, more refined appearance. It also supports visible firmness, a more even tone and renewed radiance, while helping maintain hydration, comfort and resilience.
This is where Total Repair DNA Serum earns its place. Its high-performance retinal doesn't sit in isolation. The delivery system and supporting ingredients have all been selected to broaden what this Vitamin A serum can offer.
Total Repair DNA Serum offers a genuine advance in Vitamin A technology, combining sophisticated retinal delivery with a complete formula designed for visible results and long-term skin resilience.
