Botulinum toxin type A is a purified neurotoxic protein derived from Clostridium botulinum, used in precisely micro-dosed therapeutic injections for the temporary relaxation of facial muscles responsible for dynamic wrinkles and expression lines. It is approved by the Central Drugs Standard Control Organisation (CDSCO) and classified as a Schedule H1 prescription drug in India, dispensed and administered exclusively by qualified medical practitioners.
Botulinum toxin works by blocking the release of acetylcholine at the neuromuscular junction, temporarily inhibiting muscle contraction for a period of three to six months. At Chandru ENT-Derma Care, it is administered by the dermatologist for cosmetic indications including forehead lines, glabellar frown lines (the '11 lines'), periorbital crow's feet, brow lifting and lip lines. It is also used therapeutically for primary axillary hyperhidrosis (excessive sweating), with excellent results.
- Use SPF 50 broad-spectrum sunscreen daily to slow photoageing and collagen degradation.
- Incorporate topical retinoids and peptide-based creams from the late twenties to maintain collagen density.
- Wear prescription spectacles or photochromic sunglasses to reduce squinting, which contributes to crow's feet and glabellar lines.
- Avoid smoking — it accelerates perioral fine lines and overall skin ageing.
Causes of Dynamic Wrinkles & Hyperhidrosis
Dynamic wrinkles are directly caused by repeated muscle contractions over time, compounded by loss of skin elasticity.
Repetitive Facial Muscle Contraction
Years of animated expressions — frowning, squinting, smiling — cause dynamic wrinkles to progressively deepen and eventually become static (present even at rest).
UV Radiation & Photoageing
Chronic sun exposure degrades the dermal collagen and elastin matrix, meaning that even mild muscle contraction creates visible skin folding.
Ageing & Reduced Skin Elasticity
As skin loses its capacity to 'spring back' from muscular movement, dynamic wrinkles become more pronounced and eventually become permanent static lines.
Smoking
Tobacco smoke accelerates collagen degradation and particularly contributes to fine perioral and crow's feet lines.
- Primary HyperhidrosisOveractivity of eccrine sweat glands in the axillae, palms or soles — a common condition in the warm and humid Indian climate. Botulinum toxin is highly effective in reducing excessive sweating in these areas.
About the Treatment
The dermatologist maps the facial musculature and identifies the hyperactive muscles contributing to the patient's specific wrinkle pattern. Micro-dosed injections are placed precisely within or adjacent to each target muscle belly. Results begin to emerge progressively over five to seven days and peak at two weeks. The effect lasts three to six months, after which muscle activity gradually returns to baseline.
Regular maintenance injections every four to six months can progressively train the muscles to contract with less force over time, gradually increasing the interval between treatments. The procedure takes 10–15 minutes and requires no anaesthesia for most patients.
How the Procedure Is Performed
1. Consultation & Facial Analysis
The dermatologist photographs the face at rest and during full expression to map treatment targets. Treatment goals, realistic expectations and any contraindications are discussed.
2. Topical Anaesthesia (Optional)
Ice or topical numbing cream may be applied for patient comfort, though most patients find the procedure well tolerated without anaesthesia.
3. Skin Preparation
Injection sites are cleansed with an antiseptic wipe. Make-up and skincare products are removed from the treatment area.
4. Injection
Using an ultra-fine 30- or 31-gauge needle, small precisely measured volumes of reconstituted botulinum toxin are injected at the pre-mapped sites. The procedure typically takes 10–15 minutes.
- Step 5: Post-Injection AssessmentThe dermatologist reviews the injection pattern and symmetry. Ice is applied briefly to reduce any immediate swelling or bruising.
- Step 6: Two-Week ReviewA follow-up appointment is scheduled at two weeks to assess the clinical result and perform minor adjustments if required.
Possible Side Effects
Botulinum toxin has an excellent safety record when administered by a qualified medical professional in appropriate doses.
Injection-Site Redness & Small Welts
Resolve within 20–30 minutes of the procedure.
Bruising
Resolves within 7–10 days; arnica topical gel may hasten resolution.
Mild Headache
Typically resolves within 24 hours; responds to standard-dose paracetamol.
Brow Heaviness or Asymmetry
Occurs if toxin spreads slightly beyond the intended muscle; self-resolving within 4–6 weeks; minimised by precise injection technique.
- Eyelid Ptosis (Drooping)Less than 1% incidence; caused by unintended spread to the levator palpebrae superioris muscle. Resolves spontaneously within 4–8 weeks. Apraclonidine eye drops may be prescribed to hasten recovery.
- Dry Eye or Increased TearingOccasionally reported with periorbital injections; typically transient.
Aftercare Instructions
Simple aftercare precautions for the first 24 hours maximise results and reduce bruising.
- Do not lie down flat for four hours after the procedure.
- Do not massage, rub or apply pressure to the treated area for 24 hours.
- Avoid vigorous exercise, alcohol consumption, facial massage and heat exposure (saunas, steam rooms) for 24 hours.
- Attend your two-week review appointment for clinical assessment and any minor adjustment.
- Contact the clinic promptly if you experience eyelid drooping, significant facial asymmetry or — in the context of neck injections — any difficulty swallowing.
Who Can Receive This Treatment?
