Skin longevity – a chat with Dr Angeline Yong!

“Skin longevity” is one of those buzzy phrases we’ve been hearing a lot in the beauty world – but what does it actually mean? DR ANGELINE YONG, founder of Angeline Yong Dermatology and SSKINS Medispa, explains the concept and shares her best skincare routine for improving skin longevity and skin barrier repair!

What exactly is skin longevity?

Skin longevity refers to the long-term health, resilience and function of the skin – not just how it looks today, but how well it ages over time. It’s about supporting the skin so it can continue to protect, repair and renew itself as efficiently as possible for longer.

Rather than focusing only on quick fixes or surface-level glow, it looks at the bigger picture: preserving collagen, maintaining a strong skin barrier, reducing cumulative damage from UV exposure and pollution, and keeping inflammation in check. In simple terms, it is about helping skin age better, not just look better temporarily.

How is this approach different from anti-ageing?

Skin longevity is a more holistic and forward-looking approach than traditional anti-ageing. The term “anti-ageing” tends to focus mainly on correcting visible signs of age such as wrinkles, pigmentation, or loss of firmness. Skin longevity, on the other hand, is about preserving how the skin functions over time. In other words, anti-ageing often asks, “How do we make skin look younger?” whereas skin longevity asks, “How do we help skin stay stronger and healthier for longer?” It places greater emphasis on prevention, barrier health, collagen support and reducing chronic inflammation, rather than only treating changes once they appear.

When it comes to improving skin longevity, what matters most – and what matters less than people think?

What matters most are the fundamentals done consistently over time. Daily sun protection is probably the single most important one. That’s because UV exposure is a major driver of collagen breakdown, pigmentation, and premature ageing. A healthy skin barrier also matters greatly, as skin that is chronically irritated or inflamed tends to age less well.

Lifestyle factors are also more important than many people realise. Sleep, stress, nutrition, smoking and overall metabolic health can all influence how skin repairs itself over the years.

What tends to matter less than people think is constantly chasing the newest trend, using too many active ingredients at once, or relying on expensive products without a strong foundation. In fact, over-complicating a skincare routine can sometimes lead to irritation, which works against skin longevity. The goal is not to do everything, but to do the right things consistently.

What are some aesthetic treatments or technologies that support skin longevity?

They are those that focus less on short-term correction and more on improving skin quality, resilience and repair over time. One example is QMR-based technology, such as Corage, which can be relevant from a skin longevity perspective because it is used with the aim of improving skin quality, stability, and barrier support – as healthier and more resilient skin generally tolerates environmental stress better and tends to age more gracefully over time.

Bio-revitalising light- and energy-based treatments, such as Alma’s IPL and near-infrared technologies, can address pigment irregularities and overall skin quality while supporting collagen renewal. Newer technologies such as Alma PrimeX, combining radiofrequency and ultrasound, also have a vital role in supporting firmness through deeper tissue stimulation. They’re useful not because they simply “tighten”, but because they can be incorporated into a broader strategy aimed at building and banking collagen over time.

From a dermatologist’s perspective, what matters most is not any single device, but how different technologies can be selected and combined according to the skin’s needs. In that sense, skin longevity is less about chasing one hero treatment and more about taking a thoughtful, long-term approach.

What about skincare ingredients; what do you personally recommend?

I recommend ingredients with a strong long-term track record for protecting skin health. If I had to narrow it down, sunscreen is still the single most important product category for skin longevity. After that, retinoids are among the most useful because they help support skin renewal and collagen production. Antioxidants, particularly vitamin C, can also be valuable. Meanwhile, barrier-supporting ingredients such as ceramides and hyaluronic acid help keep skin resilient and less prone to chronic irritation.

I also think it is important to remember that the “best” ingredient depends on the individual. So, while there are a few core ingredients I recommend often, the real goal is not to overload the skin, but to build a skincare routine that is evidence-based, sustainable, and suited to the skin’s needs.

Are there any ingredients or treatments you think are overhyped?

In my view, what is often overhyped is the idea that newer is always better. People can become very focused on trendy actives or having many different serums in one skincare routine, when in reality the fundamentals – sunscreen, a healthy skin barrier, and a few evidencebased ingredients used consistently – usually matter far more.

The same applies to treatments. More is not always better. Sometimes the most effective approach is a steady, well-planned one rather than constantly chasing the latest trend.

What’s something you wish more people knew about skin health?

I wish more people understood that healthy skin is not the same as perfect skin. Skin naturally changes with age, environment, hormones and stress. So the goal should not be to chase flawlessness, but to support the skin so it can function well and stay resilient over time.

I also wish more people knew that skin health is built far more by consistency than by intensity. Daily sun protection, a well-supported skin barrier, and a skincare routine appropriate for your skin type usually matter much more than constantly trying new products or doing too much at once. In fact, over-treating the skin is one of the most common ways people unintentionally compromise it.

Dr Yong’s Simple Skin Longevity Skincare Routine

Protection first in the morning: Gentle cleanse (if needed), vitamin C, a moisturiser suited to your skin type, then broadspectrum sunscreen. “If sunscreen is the cornerstone of skin longevity,” she says, “the morning skincare routine is where that foundation is built.”

Repair and renew in the evening: Cleanse thoroughly to remove sunscreen, makeup and pollutants, apply a retinoid (or peptides if your skin is sensitive) then moisturiser to support the skin barrier. For sensitive skin, keep it simple, with more emphasis on hydration and barrier repair than strong active ingredients.
