Are you worried about forehead wrinkles or crow’s feet around your eyes? Don’t worry—Botox is the “key” to instantly restoring a youthful look without surgery. In this guide, NP SPA explores every aspect of this treatment, from how it works and recommended dosages to expert tips for achieving the best possible results.
What is botox & How does it work?
The nature of botox
Botox, scientifically known as Botulinum Toxin Type A, is a purified protein derived from the bacterium Clostridium Botulinum. It may sound complicated, but all you need to know is it has been FDA-approved and widely used in medical aesthetics for many years.
How it reduces wrinkles
Facial wrinkles are divided into two types: dynamic wrinkles (caused by expressions) and static wrinkles (visible even at rest). It works by blocking signals from nerves to the muscles that create dynamic wrinkles. Once the targeted muscles relax, the skin becomes smoother, reducing the appearance of lines and folds.

Benefits of botox
Botox delivers more than just wrinkle reduction—it offers a range of aesthetic and medical advantages.
Aesthetic benefits
- Effective wrinkle reduction: Smooths forehead lines, frown lines (between the eyebrows), and crow’s feet.
- Facial slimming: Injected into the masseter muscles, Botox reduces jaw size, creating a natural V-line face without surgery.
- Brow lift: A small dose can lift the eyebrows slightly, opening up the eyes and creating a more youthful look.
- Facial contouring: Enhances overall facial balance and rejuvenation.
Medical benefits
- Hyperhidrosis treatment: Temporarily reduces excessive sweating in the underarms, palms, or soles.
- Migraine relief: FDA-approved for treating chronic migraines, helping to reduce frequency and intensity.
- Muscle spasm control: Used in conditions such as eyelid spasms and other involuntary muscle contractions.
Key advantages
- Non-Invasive: A quick procedure with no recovery time needed.
- Rapid Results: Noticeable improvements within 3-7 days.
- Safe When Done Right: Highly safe when performed by trained professionals using authentic products.
Botox dosage & common injection sites
The dosage and injection sites for Botox depend on the treatment’s purpose (aesthetic or medical) and the targeted area. Below is a breakdown of typical dosages and sites.
Botox dosage by area
Dosage varies based on wrinkle depth, muscle strength, gender (men may need higher doses), and individual factors. Typical dosages include:
- Forehead: 10–30 units – smooths horizontal lines.
- Glabellar lines (between brows): 20–40 units – reduces deep frown lines.
- Crow’s feet: 5–15 units per side – softens lines when smiling.
- Jawline slimming: 20–50 units per side – reduces masseter muscles for a V-line face.
- Brow lift: 2–5 units – creates a subtle lifting effect.

Botox is versatile, used for both beauty and medical purposes. Common sites include:

- Forehead: Smooths horizontal lines.

Note: A qualified specialist must determine the exact dosage and injection sites after assessing your skin and muscles to ensure safety and effectiveness.

Botox procedure and aftercare
A successful treatment relies on a professional procedure and proper aftercare to maximize results and minimize risks.
Standard botox procedure
The procedure is quick (10-30 minutes) and performed in a medical spa or clinic. Steps include:
- Consultation: A doctor assesses your wrinkles, muscle strength, and goals to determine the ideal dosage and injection sites.
- Dosage planning: The doctor calculates the precise Botox units needed.
- Cleansing and numbing: The treatment area is cleaned and sterilized to prevent infection. A mild numbing cream may be applied, though discomfort is minimal.
- Injection: Using a fine needle, the doctor injects Botox into pre-marked sites. The process takes about 15 minutes.
- Aftercare instructions: The doctor provides guidance to optimize results and avoid complications.
Pre- and post-care tips
Follow these guidelines to ensure the best outcome and avoid side effects:
Within 4-6 hours after injection:
- Avoid lying down or bending over: Prevents skin from spreading to unintended areas.
- Don’t touch or massage: Avoid rubbing or pressing the treated area to keep Botox in place.
- Skip vigorous exercise: Avoid activities that increase blood flow (e.g., running, yoga, weightlifting).
- Gentle facial movements: Light expressions (e.g., frowning, smiling) may help Botox settle, as advised by your doctor.
Within 24-48 hours after injection:
- Avoid heat: Skip saunas, hot showers, or prolonged sun exposure, as heat can reduce effectiveness.
- No skincare treatments: Avoid chemical peels, lasers, or other treatments in the injected area.
- Limit alcohol and smoking: These can increase bruising or affect results.
- Avoid blood thinners: Unless necessary, avoid aspirin, ibuprofen, vitamin E, or fish oil to reduce bruising risk.
Long-term care:
- Track results: Effects appear within 3-7 days, peaking at 1-2 weeks. Contact your doctor if results aren’t as expected.
- Protect your skin: Use SPF 30+ sunscreen to maintain results.
- Schedule maintenance: Lasts 3-6 months, depending on your body. Follow up with injections as recommended.
