Is Botox Dangerous? Our Dermal Fillers & Botox Safety Guide
One of the most common questions we get as an aesthetic medical clinic in London is, ‘Is Botox dangerous?’ It’s totally normal to want reassurance if you’re getting an aesthetic treatment for the first time, which is why we ensure our clients undergo a skin consultation before committing to any treatment.
Botox and dermal fillers are widely used in the aesthetic industry and are considered safe. However, they might not be suitable for everyone and can have side effects.
Find out who Botox and dermal fillers may be dangerous for, the side effects, and how to choose a safe clinic in our guide below.

What Are Botox & Dermal Fillers?
Botox and dermal fillers are some of the most popular aesthetic treatments we offer at Hannah London to enhance the face and smooth out any wrinkles.
Both of these treatments are minimally invasive and deliver natural-looking results when administered by our experienced aesthetic practitioners.
Botox works by relaxing the muscles in the face, which can help smooth out any wrinkles and fine lines, such as frown lines and crow’s feet.
Dermal fillers, on the other hand, are designed to restore volume in the face and are made from hyaluronic acid. They can help enhance your features and improve skin hydration.

Is Botox Dangerous?
Botox has been used in medical and aesthetic settings for many years and is considered very safe. In the rare case where botox goes wrong, this is down to inexperienced practitioners or incorrect placement.
Botox can have some mild side effects such as bruising, mild swelling and temporary headaches which disappear quickly.
Are Dermal Fillers Safe?
Dermal fillers are made from hyaluronic acid and are also considered very safe since they are biocompatible with the body and naturally broken down over time.
There can be some risks with dermal fillers if you have vascular complications, but this is a very rare risk and is reduced if you choose a professional aesthetic medical clinic, which is doctor-led, like Hannah London.
Common mild side effects experienced by dermal fillers are mild swelling, bruising, and tenderness after the injection.
Is Botox Safe For Pregnant Women?
Botox is not recommended for pregnant women due to the lack of research on its safety. We recommend that, as medical professionals, you postpone your Botox treatment till after pregnancy and breastfeeding to be on the safe side.
You can however, choose other more natural treatments like hydrafacials when pregnant to help tighten your skin and hydrate it, giving you a pregnancy glow.

Why Choose a Doctor-Led Aesthetic Medical Clinic?
The most important consideration when getting Botox or dermal fillers is the clinic you choose to get them done at.
Choosing a doctor-led aesthetic medical clinic is important so as you know you’re using highly regulated quality products and your practitioner is experienced with facial anatomy. This reduces any potential risks and complications.
At Hannah London, all of our aesthetic treatments are carried out by experienced medical professionals who understand both the science and aesthetic artistry of these treatments.
