1. What is Botox?
Botox is the brand name most people recognise, but in medical aesthetics, it refers to Botulinum Toxin Type A. This is a purified protein that temporarily relaxes muscles when injected in very small, controlled doses.
In aesthetic practice, we use it to soften lines and wrinkles that appear when we frown, smile, or raise our eyebrows. Unlike skincare creams that work on the surface, Botox works at a deeper level, targeting the muscle activity that contributes to visible ageing.

How does Botox work?
Botox works by interrupting the communication between nerves and muscles. Normally, nerves release a chemical messenger called acetylcholine, which tells muscles to contract. Botox blocks this signal, so the treated muscle relaxes.
Because the muscle is no longer contracting as strongly, the overlying skin looks smoother, and dynamic lines become less noticeable. Patients often describe the effect as looking “rested” or “refreshed” rather than dramatically different.
The treatment is temporary. On average, results last between 3–6 months, after which muscle activity gradually returns. For many patients, regular treatments help maintain a consistent, natural result over time.

What areas can Botox treat?
Botox is most commonly used on the upper face, but its applications go beyond wrinkle reduction. In aesthetics, it can be used for:
Advanced techniques al1so allow Botox to be used for:
This versatility makes Botox one of the most valuable tools for any aesthetic practitioner, offering both cosmetic and therapeutic benefits when applied safely and correctly.
- Forehead lines – horizontal lines that appear when raising the eyebrows
- Glabellar lines – frown lines between the eyebrows
- Crow’s feet – lines radiating from the outer corners of the eyes
Advanced techniques al1so allow Botox to be used for:
- Brow lifting - creating a subtle lift of the eyebrows for a fresher look
- Masseter reduction - slimming the lower face by relaxing the jaw muscles
- Neck bands - softening vertical lines in the neck (platysmal bands)
- Gummy smile correction - reducing excessive gum show when smiling
- Medical concerns - including hyperhidrosis (excessive sweating), bruxism (teeth grinding), and chronic migraines
This versatility makes Botox one of the most valuable tools for any aesthetic practitioner, offering both cosmetic and therapeutic benefits when applied safely and correctly.
2. What are Dermal Fillers?
Dermal fillers are injectable gels used to restore or add volume beneath the skin. Most modern fillers are made of hyaluronic acid (HA), a substance found naturally in our skin that helps maintain moisture and elasticity. Because hyaluronic acid attracts water, it not only fills space but also improves skin hydration and texture.
In aesthetics, dermal fillers are often described as “volumisers” because they can replace age-related volume loss, reshape features, and enhance natural contours. Unlike Botox, which relaxes muscles to smooth lines, dermal fillers work by physically adding structure and support beneath the skin.

How do dermal fillers work?
Dermal fillers are injected into carefully selected layers of the skin or deeper tissues, depending on the treatment area. Once placed, they can:
The results are visible immediately after treatment, which makes fillers especially appealing to patients. Depending on the product used and the area treated, results can last 6 to 18 months before the body gradually breaks down the filler.
- Plump and smooth wrinkles or folds that appear when skin loses elasticity
- Replace lost volume in areas like the cheeks or temples, restoring youthful balance
- Define and contour facial features such as the jawline, chin, or nose
- Enhance lips by adding shape, volume, or hydration
- Rejuvenate the skin through the hydrating effect of hyaluronic acid

What areas can dermal fillers treat?
Dermal fillers are versatile and can be used in many parts of the face. Common treatment areas include:
In skilled hands, fillers can also be used in advanced procedures, such as non-surgical rhinoplasty (liquid nose job) or full-face rejuvenation, where multiple areas are treated for a balanced, natural look.
- Lips – enhancing volume, shape, or hydration
- Cheeks – restoring fullness or creating contour
- Jawline and chin – improving balance and definition
- Nasolabial folds – softening the lines from nose to mouth
- Tear troughs – reducing hollowing under the eyes
