3 Things Dr. Byron Would Never Do

In the fast-paced world of aesthetic treatments, it’s easy to get caught up in trends and quick fixes. But at nüseoul, we take a different approach, one rooted in Korean beauty principles, where the focus is on prevention, skin health, and natural-looking results over time. We believe in making smart, considered decisions that work with your face, not against it.

That’s why we asked our in-house doctor, Dr. Byron, to share the top three things he would never do to his own face. With his background in ophthalmology, microsurgery, and advanced facial anatomy, not to mention his training with the British Aesthetics Academy, his insights reflect the safety-first, long-view

philosophy that defines Korean aesthetic medicine.

First, who is Dr. Byron?

Before we get into the list, let’s talk credentials. Dr. Byron is not just a trained injector. He’s a GMC-licensed ophthalmologist with five years of microsurgical training in the NHS, including specialisation in oculoplastics, the intricate structures around the eyes. He trained and works at Moorfields and Western Eye Hospitals, two of the most prestigious eye hospitals in the world.

Why does that matter in aesthetics?

Because injectables are not just cosmetic, they’re medical. When you’re working millimetres away from major arteries, nerves, and the eyes themselves, precision isn’t optional. It’s essential.

Add to that Dr. Byron’s training with the British Aesthetics Academy, and his background in photography (giving him a finely tuned eye for facial balance and natural results), and you have a practitioner who approaches your face with both clinical insight and aesthetic sensibility.

So when he says there are things he won’t do, either for himself or for his patients, we listen.

1. Skip SPF, even once

Twins (natural age 61) with significant difference in sun exposure. Twin B (B) had approximately 10 hours per week greater sun exposure than twin A (A). Twin A had a body mass index 2.7 points higher than that of twin B. The perceived age difference was 11.25 years.

If you’ve ever rolled your eyes at another reminder to wear sunscreen… we get it. It’s not a glamorous step. It doesn’t give you instant results. It doesn’t come in a chic syringe. But according to Dr. Byron, it’s the single most important thing you can do for your skin.

“Every patient I see wants to preserve or improve their skin. Yet many of them still skip SPF,” he says. “The truth is, no treatment, no laser, no injectable, no miracle cream, can undo the damage caused by long-term UV exposure.”

UVA rays, the kind responsible for premature ageing, are present year-round and can pass through clouds and windows. They break down collagen, trigger pigmentation, and contribute to fine lines, sagging, and uneven texture, often before we even realise it.

And from a medical perspective, the stakes are even higher. UV exposure is a known risk factor for skin cancers, including basal cell carcinoma and squamous cell carcinoma, which often occur on the eyelids and around the eyes, areas Dr. Byron has treated firsthand in his ophthalmology practice.

“I’ve seen the long-term effects of sun damage under a microscope. It’s not just about looks, it’s about cellular health. If you do one thing for your face, make it sunscreen.”

Dr. Byron’s SPF habits:

He uses SPF 50 or higher every morning, 365 days a year.
Reapplies mid-day when outdoors or near windows.
Prefers Korean sunscreens for their elegant, lightweight feel and superior wear under makeup.

2. Get under-eye filler

Dark circles. Tired eyes. Hollow tear troughs. It’s no wonder under-eye filler has become one of the most requested treatments in aesthetic clinics. And while it can deliver dramatic improvements when done carefully, Dr. Byron himself wouldn’t ever get it.

“The under-eye area is one of the most anatomically dangerous zones to inject,” he explains. “Even with perfect technique and the right product, there’s a risk of severe complications, including blindness.”

This isn’t scaremongering, it’s a real, medically documented risk. The infraorbital artery, which runs beneath the eye, shares a common arterial system with the eye. If filler is accidentally injected into this network, it can block blood flow to the retina. The result? Sudden, irreversible vision loss.

As an ophthalmologist, Dr. Byron has treated patients with vascular occlusions, including those caused by cosmetic procedures. And the truth is, once vision is gone, there’s no reversing it.

Beyond the risk factor, under-eye filler also comes with aesthetic downsides. The skin in that area is incredibly thin, making it prone to Tyndall effect (a bluish discolouration), puffiness, and migration over time.

“In many cases, I can achieve better and safer results with skin boosters or polynucleotides,” says Dr. Byron. “These improve the quality of the skin itself, rather than just adding volume.”

Better alternatives for tired eyes:

Polynucleotides: A regenerative treatment that strengthens the skin barrier and boosts hydration.
Targeted skincare: Brightening serums, peptides, and retinoids can improve pigment and texture over time.
Lifestyle support: Iron levels, sleep hygiene, hydration, and stress all play a role in under-eye appearance.

3. Get nose filler

Nose filler, also known as the “liquid nose job”, has become a social media favourite for its ability to straighten bridges and lift tips without surgery. But for Dr. Byron, it’s a hard no.

“Of all the places you could inject filler, the nose is one of the most high-risk. I would never do it on myself.”

The reason? Again, it comes down to vascular anatomy. The nose is home to several arteries that connect directly to the ophthalmic and facial circulations. If filler enters one of these vessels, it can travel backward and block blood supply to the eye or brain.

This can lead to blindness, skin necrosis, or, in extremely rare cases, stroke.

“In ophthalmology, I’ve seen what happens when those arteries are compromised,” says Dr. Byron. “It’s not worth the risk, especially when there are safer ways to achieve facial balance.”

There’s also the issue of filler migration and unpredictable outcomes over time. The nose is a dynamic structure, meaning that even small changes in pressure, facial movement, or filler breakdown can distort results.

If you’re unhappy with your nose:

Consider surgical rhinoplasty for structural, lasting changes.
Use cheek or chin filler to enhance facial harmony without touching the nose itself.

A different kind of aesthetics

Korean aesthetics, where beauty is subtle, skin-first, and rooted in balance. We focus on gentle, gradual enhancements that preserve your natural structure and respect the complexity of the face, because the best results don’t shout; they whisper.

With doctors like Dr. Byron, whose expertise bridges both Eastern and Western medical disciplines, we’re committed to delivering care that is as precise as it is thoughtful. If you’re curious about what aesthetic treatments can look like when safety, science, and harmony are the priority, we’d love to welcome you.
