Biohacking Beauty: Dr Sara on PLIM, Skincare And The Tech She Actually Trusts

A leading doctor at Knightsbridge’s renown Dr Rasha Clinic and ambassador for PLIM, Dr Sara sits exactly where medicine, technology and fintech collide.

PLIM is the ‘buy-now-pay-later’ platform revolutionising how we finance our cosmetic treatments: with 0% interest, instant pre-approval, and a marketplace of over 836 vetted clinics. The idea is that paying for aesthetic treatments shouldn’t be a lump-sum gamble but a planned, long-term investment in your skin.

That philosophy is personal. After developing rosacea herself and treating it with energy-based devices and medical-grade skincare, she understands the emotional weight of skin. “I know what it’s like to feel like you don’t want to leave the house without makeup,” she says.

Scroll on as she shares the devices, diagnostics and tech-powered rituals behind her biohacking beauty routine…

Biohacking Beauty With Dr Sara:

I’m an aesthetic doctor…

With a particular interest in regenerative aesthetics, skin health and holistic wellbeing. After graduating from Kuwait University in 2017, I trained across several medical specialties before pursuing my passion for aesthetics in London. Coming from a family with a strong artistic background, I’ve always been fascinated by the relationship between beauty, proportion and confidence, which naturally led me towards aesthetic medicine.

My journey into aesthetics was inspired by….

For me, it was always a combination of medicine and artistry. I’ve always loved how aesthetic medicine allows you to make subtle changes that can have such a positive impact on someone’s confidence.

It also became very personal when I developed rosacea myself. I went through the process of treating it with energy-based devices and medical-grade skincare, and it completely changed how I felt about my skin. It also gave me a much better understanding of what so many of my patients go through. I know what it’s like to feel like you don’t want to leave the house without makeup, and sometimes all people really want is to feel comfortable in their own skin which definitely influenced the way I practise today.

The platform I find most useful…

I think platforms like PLIM represent an important shift in helping patients access evidence-based treatments and approach aesthetic care as part of a long-term wellness strategy.

At Dr Rasha Clinic, we believe that aesthetics should never exist in isolation. The future of beauty lies in combining advanced treatments with lifestyle optimisation, prevention and longevity medicine. This is where platforms like PLIM are incredibly valuable, as they allow patients to access and plan treatments in a way that supports long-term investment in their health and wellbeing rather than focusing on quick fixes.

 

The gadget I can’t live without is…

I really like my Whoop because it’s completely changed the way I think about sleep. Before, I’d have good days and bad days without really understanding why. Now I can actually see how well I’ve slept and how recovered I am, which helps me plan my day a bit better. I genuinely find health tracking apps useful, particularly those that monitor sleep, recovery and activity levels.

My morning routine is…

Centred around consistency rather than complexity. I start with hydration, take my supplements and prioritise movement whenever possible. From a skincare perspective, I focus on antioxidant protection, skin barrier support and daily SPF. If I can spend some time outdoors in natural light early in the morning, even better.

My evening wind-down ritual…

Sleep is probably the most underrated beauty treatment we have. I try to maintain a consistent bedtime routine, minimise screen exposure in the evening and create a calm environment before sleep. My evening skincare routine focuses on repair and regeneration, using ingredients that support skin renewal overnight.

The treatments that make the biggest difference…

Sleep optimisation has probably had the biggest impact overall. The in-clinic red light devices are much more powerful than at-home masks, so you’re going to see better results, particularly when it comes to reducing inflammation, supporting healing and improving overall skin health. I think home devices are great for maintaining results between treatments, but they don’t replace professional treatments.

I’m a big fan of lymphatic drainage. It can make a real difference to puffiness and circulation, especially after long-haul flights. We have a lot of international patients, and it’s one of the treatments we often recommend after travel to help reduce fluid retention and restore normal lymphatic flow.

The supplements I swear by are…

I always think supplements should be personalised rather than taking lots of products just because they’re trending. I tend to focus on the foundations first, so things like vitamin D, omega-3s, magnesium and making sure I’m getting enough protein.

I’m also a big believer in supporting hair health from within. Our Dr Rasha Hair Supplements contain ingredients like marine collagen, biotin, zinc and a blend of essential vitamins that help support healthy hair growth, improve strength and density, and maintain a healthy scalp. Healthy hair is influenced by so many factors, so I see supplements as part of a broader approach alongside good nutrition, stress management and overall wellbeing.

 

Cold plunges vs infrared saunas…

I think both have their place. Infrared sauna is something I personally enjoy because of the relaxation and recovery benefits. Cold exposure can be beneficial too, but I personally struggle with the cold.

An overhyped beauty trend is…

The idea that one treatment or one device can completely reverse ageing. Healthy ageing requires a combination of treatments, lifestyle optimisation and realistic expectations. There is no single magic solution.

If you could invent a beauty product tomorrow…

I would love to see a genuinely personalised longevity and skin health platform that combines biomarkers, hormonal health, lifestyle data, genetics and advanced skin analysis to create truly bespoke prevention and treatment plans.

The ingredients and skincare I swear by…

Retinoids remain one of the most evidence-based ingredients we have. I also love vitamin C, peptides, growth factors and, of course, SPF. The most effective skincare ingredients are often the ones supported by decades of clinical evidence.

I think we need to be more transparent about…

The difference between strong scientific evidence, emerging evidence and marketing claims. Patients are much more informed now, and they deserve honest conversations about what we know, what we don’t know, and why we’re recommending a particular treatment.

In aesthetics, we also use some treatments off-label, which is actually very common in medicine. That doesn’t necessarily mean they don’t work, it simply means they haven’t been licensed for that specific indication. Often there’s growing clinical experience and published evidence supporting their use, but it’s important that patients understand when something is off-label so they can make an informed decision.

For me, it’s all about transparency. Patients should feel confident that their practitioner is explaining the evidence, discussing the risks and benefits, and recommending treatments based on both clinical research and experience, rather than trends or marketing.

 

When it comes to screen-time…

I think the impact on wellbeing is probably more significant than the direct effect on skin. Increased screen time can negatively affect sleep quality, stress levels and recovery, all of which ultimately influence skin health and ageing.

One incredible wellness practice…

Prioritising sleep and recovery. We often focus on adding more treatments, supplements and devices, but improving sleep quality has had the greatest impact on both my energy levels and overall wellbeing.

If I could give my 18-year-old self one piece of skincare advice would it be…

Wear SPF every day, prioritise your health from the inside out and remember that prevention is always easier than correction.
