1.What is Botox?

Botox is a trading name for Botulinum toxin, is a purified protein produced by the clostridium botulinum bacteria. Botox acts by blocking acetylcholine, the chemical which transmits electrical impulses that cause muscle contractions.  It is usually injected, into the face, to “paralyse” the muscles and has a temporary effect on the reduction of fine lines and wrinkles. Botox is a prescription-only medicine, which should only be injected by a suitably qualified health professional or Doctor



2.How is Botox used?

The Botox is injected into the skin using very fine needles. The lines and wrinkles that appear as we become older are actually results of muscle movement over the passage of time. As the skin become less elastic then repeated muscle contractions result in tightened muscles around some areas leaving lines and wrinkle. When Botox is injected into these muscle areas, it blocks the nerve/electrical impulses from reaching that area and, as a result, the muscle relaxes reducing the appearance of line and wrinkles.



3.Does a Botox injection hurt?

As with any needle procedure there can be some discomfort from time to time. A fully experienced and trained Doctor will usually have exceptional needle skills and aim to make the process as comfortable as possible. When the Botox is injected into the skin, there can be a minor stinging sensation that lasts only for a few seconds. Once the injection is complete, there is usually no discomfort. The fact that no local anaesthetic is required suggests only very minor levels of discomfort.



4.Where can Botox be injected?

The most common areas for the use of Botox for assisting with the smoothing of lines and wrinkles to the face, such as Crows feet, frown lines, forehead lines etc. Botox may also be used in other areas of the body yet we currently only retain application to the facial area and underarm area (to assist with the prevention of sweat).



5.How long does the Botox treatment last?

Usually the most noticeable results start to appear over the first 2-3 days. The effects of Botox can vary between clients yet on average it usually last three to five months. Due to the fact that the muscles under the skin start to contract again as the Botox wears off then generally the lines and wrinkles will start to re-appear after this period of time. After several treatments, the effects of Botox may begin to last longer, sometimes up to six to eight months.



6.How safe is Botox?

Clinical use of Botox is the result of more than 100 years of study into botulinum toxin type A. Botox is one of the world's most widely-researched medicines with approximately 2,300 publications in peer-reviewed scientific and medical journals. Botox is currently approved in approximately 85 countries around the world as well as the UK. In the correct hands Botox has been safely and successfully used in both ophthalmology and for wrinkle therapy for many years now. With controlled amounts used for wrinkle therapy then the only possible side effects are temporary and localized to the area of the injection. Below are some minor side effects that can be a result of a Botox procedure.

  • Small area of redness with the treatment localised site lasting 2-3 hours (common)
  • Minor bruising or swelling of treatment localised area (less common)
  • Occasional headache (less common)
  • Temporary droop of eyebrow or eyelid (very rare)
  • Double vision (very rare)


7.What is needed in terms of Aftercare?

Within the first 6 hours after the treatment you should consider the following:-

  • Gently exercise the treatment areas by frowning, smiling, squinting and lifting the eyebrows occasionally - this will optimise your result
  • DO NOT rub, massage or stroke the treatment areas – this can spread the product increasing the risk of complications. Also as the skin has been broken by needles there is a risk of infection
  • AVOID lying flat or bending down excessively
  • AVOID very strenuous physical exercise and activity
  • AVOID alcohol, aspirin and ibuprofen for 24 hours which can increase the risk of stronger bruising and swelling

1.What are Dermal Filler?

Dermal fillers are a collagen material made of synthetic or often natural substances. The fillers are injected into the dermis layer of the skin for the purpose of augmenting soft tissues. Dermal fillers have had a significant rise in their application over the past ten year due to aesthetic reasons, namely they help correct skin conditions which develop as a result of ageing such as creases, folds and wrinkles. Dermal filler can also be used to enhance the lips and cheeks



2.How Dermal Filler work?

Dermal Filler proprietary component is Hyaluronic acid. This is a naturally occurring substance found in humans and animals. It gives the skin its plumpness and as we age it decreases, contributing to the ageing process. It also acts as a humectant which means that it attracts water so can be used to rejuvenate the skin and restore volume. Derma Fillers use a synthetic form of Hyaluronic acid with very low instances of allergic reaction. Dermal filler ultimately act as a ‘plumpling’ agent within the skin. They technically work as replenishment for the natural collagen which has been rendered less effective during the ageing process. Dermal fillers are injected into the skin using fine needles. They can plump-up the area which has received the injection, levelling it with other areas of the skin and making it look plumped out, even and no longer sunken. Ultimately, the plumped up skin looks firmer, young and refreshed.



3.Do Dermal Filler injections hurt?

As with any needle procedure there can be some discomfort from time to time. A fully experienced and trained Doctor will usually have exceptional needle skills and aim to make the process as comfortable as possible. As well as the dermal filler itself containing ‘lidocaine’ (anaesthetic) a topical anaesthetic is also applied to the area of the skin prior to treatment, this gives a numbing effect to the treatment area and greatly reduces any discomfort.



4.Where can Dermal Fillers be injected?

There are various forms of dermal filler, with varying quality, results and price. We look for use the best available products in the market and this is why we only use Juvederm Ultra in all of our applications. We use Juverderm Ultra for Crows feet, frown lines and vertical lip lines to give the ultimate in firm, natural skin re-balancing.



5.How long do Dermal Fillers Last treatment last?

Usually the most balanced results start to appear after the first 48hrs, you can then expect the beneficial effects of the Juverderm Ultra to last for 6-12 months. Obviously being a temporary treatment, patients should make sure to have repeated treatments after the standard period of 12 months.



6.How safe are Dermal Fillers?

There are a few issues and problems with dermal fillers but these are in general very uncommon, even rare in places. Although dermal fillers are regarded as a safe aesthetic procedure, it is worth always consulting your treatment Doctor on the matter, as any possible side effect and possible issue can be resolved with proper technique and professional experience of the aesthetic practitioner/surgeon. If you have any known allergies or you take any medicine or have a condition which makes you more sensitive to the procedure it is very important you consider the risks before having the treatment. Blood thinning medicine such as warfarin can also cause issues during the procedure and should as such be reported to the aesthetic practitioner/surgeon. With a competent Doctor who holds all the personal information needed your dermal fillers treatment should be completely risk free. Some of the most common side affect of the treatment are shown below:-

  • Immediate redness, swelling, burning and itching around the treatment site are COMMON and should settle within the first few hours
  • Bruising and swelling lasting up to 2 weeks are LESS COMMON and should resolve spontaneously
  • Slight blue discolouration of the treatment area is LESS COMMON
  • Cold sores may RARELY erupt following lip augmentation – this should be treated with Zovirax cream from the pharmacy
  • Tissue infection / abcess is RARE and can be treated with antibiotics
  • Granuloma (tissue nodules) are VERY RARE and can be treated with injection of steroid into the affected area
  • Tissue necrosis (sores) is VERY RARE and usually resolves
  • Hypersensitivity / allergy is VERY RARE and can be treated with antihistamines


7.What is needed in terms of Aftercare?
  • AVOID wearing makeup for up to 12 hours.
  • AVOID sun, as well as saunas and steam rooms, for 2 weeks.
  • AVOID any additional forms of treatment in the treated area for the next 7 days
  • DO NOT rub, massage or stroke the treatment areas – this can spread the product increasing the risk of complications and uneven skin balance and as the skin has been broken by needles there is a risk of infection
  • AVOID very strenuous physical exercise and activity
  • AVOID alcohol, aspirin and ibuprofen for 24 hours which can increase the risk of stronger bruising and swelling
