Q. How do cosmetic injections work?
Doctor Answer is medically reviewed by SecondMedic medical review team.
The mechanism of action for cosmetic injections depends on the type of injection being used. Here's how two common types of cosmetic injections work:
1. Botox (Botulinum Toxin) Injections:
- Botox works by temporarily blocking the nerve signals that control muscle contractions. It does this by inhibiting the release of acetylcholine, a neurotransmitter, at the neuromuscular junction.
- When Botox is injected into specific facial muscles, it relaxes those muscles by preventing them from contracting as strongly. This relaxation reduces the appearance of wrinkles and fine lines that are caused by repeated muscle movements.
- The effects of Botox typically become noticeable within a few days to a week after the injection and can last for several months. Eventually, the nerve signals regain their normal function, and the muscle contractions return, necessitating repeat treatments to maintain the results.
2. Dermal Filler Injections:
- Dermal fillers work by adding volume and structure to the treated area. The exact mechanism varies depending on the type of filler used.
- The most common type of dermal fillers are made from hyaluronic acid, a natural substance found in the skin. Hyaluronic acid fillers attract and hold water, which adds volume and hydration to the skin. This can fill in wrinkles, lines, and areas of volume loss.
- Other fillers, like those containing collagen or calcium hydroxylapatite, stimulate the body's own collagen production, which helps to improve skin elasticity and firmness.
- The results of dermal filler injections are immediate, and they can last anywhere from several months to over a year, depending on the specific filler used and the individual's metabolism.
In both cases, the goal of cosmetic injections is to achieve a more youthful and rejuvenated appearance by reducing wrinkles, adding volume, or enhancing specific facial features. The results are temporary and typically require periodic touch-up treatments to maintain the desired look. The specific technique and product used can vary depending on the patient's goals and the expertise of the practitioner. It's essential to consult with a qualified healthcare provider to discuss your individual needs and expectations.

Answered by Secondmedic ExpertDealing with excessive dandruff leading to hair loss can be frustrating, but there are effective ways to address this issue. Here's what you can do:
1. Switch to a Gentle Shampoo: Opt for shampoos specifically designed for dandruff, containing ingredients like ketoconazole, zinc pyrithione, coal tar, or selenium sulfide. Use these shampoos regularly to reduce dandruff buildup.
2. Scalp Massage: Gently massage your scalp while shampooing to help remove flakes and improve blood circulation, which can promote healthier hair growth.
3. Avoid Hot Water: Wash your hair with lukewarm water instead of hot water, as hot water can dry out your scalp and worsen dandruff.
4. Balanced Diet: Ensure you're eating a balanced diet rich in vitamins and minerals essential for healthy hair and scalp, such as omega-3 fatty acids, zinc, and B vitamins.
5. Manage Stress: Stress can exacerbate dandruff problems. Practice stress-relief techniques like meditation, yoga, or regular exercise to help manage stress levels.
6. Apple Cider Vinegar Rinse: Consider using diluted apple cider vinegar as a rinse after shampooing. It can help restore the scalp's pH balance and reduce dandruff.
7. Consult a Dermatologist: If the issue persists despite trying home remedies or over-the-counter solutions, seek advice from a dermatologist. They can provide a personalized treatment plan tailored to your specific scalp condition.
Remember, consistency is key when dealing with dandruff. Give these remedies some time to work, as immediate results might not always occur. It's essential to find what works best for your scalp, so don't get discouraged if you don't see immediate improvements.
Taking care of your scalp health not only addresses dandruff but also aids in reducing hair loss associated with this issue. Feel free to incorporate these tips into your routine and observe how your scalp responds. If the problem persists or worsens, seeking professional guidance is always recommended.
