Spider veins, or thread veins, are caused by the dilation of small blood vessels near the skin’s surface.

Factors contributing to their development include genetic predisposition, hormonal changes (such as during pregnancy or menopause), and prolonged exposure to sun or extreme temperatures.

Other risk factors include prolonged standing or sitting, obesity, and ageing, which weaken the vessel walls and valves. Spider veins are often seen on the legs and face and are generally harmless but can be a cosmetic concern.

Maintaining a healthy lifestyle, managing weight, and protecting your skin from sun damage can help reduce the risk of developing spider veins.

We offer a range of treatment options for varicose veins, including VenaSeal™ – the most up-to-date method of treating varicose veins that causes less pain and allows you to get back to normal almost immediately, without the hassle of wearing bandages or compression stockings.

Get in touch with our friendly team, and we’ll help you find the right varicose vein treatment.

We have an exciting new addition to the clinic - Visia skin analysis. 

We’ve had a growing focus in the clinic on skin quality and skin health over the years with more and more investment in lasers and devices that improve skin quality as the foundation of what we do in aesthetic medicine. 

The Visia is a great tool for helping us to analyse the skin and track progress of treatments over time. As well as doing a thorough analysis of all the components of sun damage and skin health, it also gives us an estimate of our ’true age’, which is a reflection of the condition of our skin compared with average for our age. 

This is one of my own analysis images. It got my ’true age’ pretty much spot on with my chronological age, which is perhaps surprising given that I spent most of the 90s lying under a sun bed. What was interesting is that I scored really well on superficial pigment and redness, which is consistent with the fact that I love BBL and have a treatment a few times per year. I scored less well on deeper pigment and texture issues, which I guess is consistent with the fact that I’ve not had a Halo laser for nearly 4 years now. So I guess I will be booking another Halo for myself very soon!!!

We're offering the Visia skin analysis free as part of our laser consultation process. If you're interested in laser treatment, come in for a consultation with Dr Sharon and you’ll have your analysis done as part of planning your treatment strategy. 

You’ll also be scanned again after your course of treatment so we can track your progress. 

What do you think of this new addition to the practice?
Laser eye rejuvenation! Thank you to our lovely patient for allowing us to share her photos, just one week after her laser eyelid rejuvenation. 

Crepe skin, loose skin, wrinkles are all common signs of ageing around the eye which do not respond well to surgery. The optimal treatment for these problems is laser resurfacing - which is exactly what this patient had. 

We’ve been performing these treatments in the clinic for several years, although I’ve recently modified the technique to achieve incredible results with less downtime.

What do you think?
With darker evenings and  fewer social engagements, January is a great time to think about treatments which benefit from a little down time or those that will deliver their best results by spring. 

Here’s Dr Darren with his top recommendations for treatments to have over the winter months, including Sofwave, HALO, full-field resurfacing and varicose vein treatment, all of which will deliver beautiful results in time for the weather getting better and social calendars filling up! 

Which treatments are you planning?
Another year, another round of incredible transformations from our team at McKeown Medical! 

Eye bags banished, jowls lifted, skin refined, veins gone. Thank you so much to all of our patients who have allowed us to share their photos with you and thank you to our incredible team who work so hard to take care of every patient who trusts us with their care. 

Here’s to 2026 and another year of incredible transformations!
