When you are considering botox, many questions come to mind: When does it start working? Will my expressions change? What should I watch for afterwards? Is masseter botox for teeth clenching the same as facial botox?

In this guide, prepared for our clinic in İzmit, we answer the most common questions in plain language. Our approach is to assess your facial anatomy, your health and your expectations together, and to build a plan that suits you.

1. What is botox and what does it do?

The procedure commonly known as "botox" is the injection of a medicine containing botulinum toxin into target muscles. By temporarily reducing the movement of the muscle, it softens the appearance of lines that become visible with expression. Botox itself is one of the brands within this group of medicines. Botox does not affect the volume of the skin. I describe the general approach on the botulinum toxin page.

2. Which lines does frown-line botox affect?

The lines that form when you frown are one of the uses of botulinum toxin. However, deepened lines that are visible even without expression should not be expected to disappear completely. In these lines, softening is seen. Muscle movement and the depth of the line in the skin are assessed together.

3. How is botox done, and does the needle hurt?

First, your face is assessed at rest and while making expressions. Photographs are taken at set angles and kept on record. An anaesthetic cream is then applied to your face. After a waiting period, the appropriate points are identified and the medicine is injected with fine needles. A brief sting or tenderness may be felt.

The medicines you take, previous treatments and health problems should be reported to the physician before the procedure; prescription medicines should not be stopped on your own.

4. What is the difference between botox and filler?

Botox reduces muscle movement. Filler, depending on the product and the area, provides volume or tissue support. That is why a line caused by frowning and a need for volume in the lips are not handled the same way. Which procedure is appropriate is determined by the cause of the appearance. I explain what filler does on the dermal fillers page.

5. Does lip botox replace lip filler?

The procedure known as a "lip flip" can, in selected people, turn the upper lip slightly outwards; it does not add volume to the lip. It does not give the same result as lip filler. Because it affects the muscles around the mouth, it carries risks such as temporary difficulty drinking or speaking. Suitability and the product's approved uses should be assessed by the physician.

6. What is baby botox?

Baby botox is not a separate medicine or a standard treatment name. It is generally used to describe treatments that aim for more limited muscle relaxation. There is no rule that "a lower dose gives everyone a better result". The dose is planned according to muscle strength and the intended effect.

7. How many days does botox take to settle, and what should I expect from the treatment?

The effect does not appear immediately; most people notice the first changes within 3–7 days. A review is usually done about two weeks later; this period may vary with the product and the treated area.

Decisions about an additional dose should not be based on the appearance in the first few days. Rather than taking the result in someone else's photograph as the measure for your own face, compare against your own starting appearance.

8. How long does botox last?

The effect of treatments for facial expression lines usually lasts around 3–4 months. The duration can vary with the product used, the dose, the area and individual response. The effect is not permanent; the timing of repeat treatment is decided together with the physician.

9. What should I watch for after botox?

It is important not to rub or massage the treated area. Avoid applying pressure to the area when putting on make-up. Ask your physician when you can return to intense exercise, and follow the aftercare advice you are given. Most people can return to daily life within a short time.

10. Is botox harmful, and what are the side effects?

Botox is a medical procedure and it is not without risk. Tenderness, redness, swelling or bruising may occur at the injection site. Asymmetry due to unintended muscle effects, or drooping of the brow or eyelid, can also occur.

If you develop difficulty swallowing, speaking or breathing, generalised muscle weakness or signs of a serious allergic reaction, seek emergency care without waiting. These symptoms are not limited to the day of the procedure.

11. What should I do if my eyelid droops after botox?

Inform the physician who performed the treatment. Brow drooping and eyelid drooping are different conditions and need to be distinguished by examination. Do not use eye drops on your own or massage the area. If double vision or reduced vision accompanies it, get assessed without delay.

12. What is masseter botox, and how is it assessed for teeth clenching?

The masseter is one of the jaw muscles that helps with chewing. Botulinum toxin injected into this muscle can reduce the force of contraction. Studies have shown a reduction in the intensity of muscle activity during clenching; this does not mean the cause of the clenching has been removed.

Jaw pain and teeth clenching can have different causes. A dental assessment, a night guard where needed and other approaches should be considered together. It cannot be said to be effective for all jaw joint problems.

13. What should I expect after masseter botox?

The effect on the muscle and the change in facial appearance may not appear at the same pace. Results vary from person to person. Unwanted effects such as temporary weakness in chewing or a change in the smile can develop. If there is a noticeable complaint, inform the physician without waiting for the review date.

14. What determines the price of botox and masseter botox?

The fee can vary with the treated area, the product used, the required dose and the scope of the assessment. Facial botox and masseter treatment require different plans. A single price seen online does not explain the scope of the treatment that is right for you. The need and the plan have to be clear first.

15. Is there a difference between Dysport, Botox and other botox brands?

There are different medicines containing botulinum toxin. Their formulations and dose units are not the same; one brand's unit cannot be considered directly equivalent to another's. As much as the choice of brand, the reliable supply of the product, planning suited to the person and correct technique also matter.

16. Is botox also used for migraine?

Yes, certain botulinum toxin products can be used in suitable patients for the preventive treatment of chronic migraine. It is not appropriate for every headache or type of migraine. Migraine treatment requires a different assessment and protocol from cosmetic facial botox.

17. Can a "botox-effect" cream or serum replace the injection?

The phrase "botox effect" does not mean that a product has the same effect as a botulinum toxin injection. Depending on their ingredients, skincare products can support hydration and surface appearance. They should not be considered equivalent to an injection that targets muscle movement. That is why you should look at a product's ingredients and evidence, not its marketing name.
