Precautions for Hyaluronic Acid Injection
Hyaluronic acid (HA) injection is a popular cosmetic procedure used to improve the appearance of the skin. HA is a naturally occurring substance that helps to keep the skin hydrated and elastic. When injected into the skin, HA can help to reduce wrinkles, fine lines, and other signs of aging.
While HA injection is generally safe, there are some potential risks and side effects that you should be aware of before undergoing the procedure. These include:
Bruising and swelling: Bruising and swelling are common side effects of HA injection. They typically subside within a few days.
Infection: Infection is a rare but serious side effect of HA injection. Symptoms of infection include redness, swelling, pain, and fever.
Allergic reaction: Allergic reactions to HA are rare, but they can occur. Symptoms of an allergic reaction include hives, swelling, and difficulty breathing.
Granuloma formation: Granulomas are small, hard lumps that can form at the injection site. They are usually harmless, but they can be unsightly.
Vascular occlusion: Vascular occlusion is a rare but serious complication of HA injection. It occurs when the HA blocks a blood vessel. Symptoms of vascular occlusion include pain, swelling, and discoloration of the skin.
Who Should Not Get Hyaluronic Acid Injections?
HA injection is not suitable for everyone. You should not get HA injections if you have:
Active acne: HA injections can worsen acne.
A history of keloids: Keloids are thick, raised scars that can form at the injection site.
A bleeding disorder: HA injections can increase your risk of bleeding.
An autoimmune disease: Autoimmune diseases can increase your risk of side effects from HA injections.
If you are pregnant or breastfeeding: The safety of HA injections during pregnancy and breastfeeding has not been established.
How to Prepare for Hyaluronic Acid Injection
Before your HA injection, you will need to:
Tell your doctor about your medical history: This includes any allergies, bleeding disorders, or autoimmune diseases.
Avoid taking blood thinners: Blood thinners can increase your risk of bleeding during and after the procedure.
Avoid drinking alcohol: Alcohol can also increase your risk of bleeding.
Bring a friend or family member with you: This person can help you get home safely after the procedure.
What to Expect During Hyaluronic Acid Injection
Your HA injection will be performed in a doctor's office or clinic. The procedure typically takes about 30 minutes to an hour.
During the procedure, your doctor will:
Clean the injection site: Your doctor will clean the injection site with an antiseptic solution.
Inject the HA: Your doctor will inject the HA into the desired areas of your skin.
Massage the injection site: Your doctor will massage the injection site to help the HA spread evenly.
What to Expect After Hyaluronic Acid Injection
After your HA injection, you may experience some bruising, swelling, and tenderness. These side effects typically subside within a few days.
You should avoid touching or rubbing the injection site for 24 hours. You should also avoid strenuous activity for 24 hours.
You will see the results of your HA injection gradually over the next few weeks. The full results of the procedure may take up to two months to appear.
How Long Do Hyaluronic Acid Injections Last?
The results of HA injections typically last for 6 to 12 months. However, the longevity of the results can vary depending on the individual patient.
Factors that can affect the longevity of the results include:
The type of HA used: Some types of HA last longer than others.
The amount of HA injected: The more HA that is injected, the longer the results will last.
The injection technique: The way the HA is injected can affect the longevity of the results.
The patient's age: The older the patient, the shorter the results will last.
The patient's lifestyle: Factors such as smoking and sun exposure can shorten the longevity of the results.
Tips for Extending the Longevity of Hyaluronic Acid Injections
There are a few things you can do to extend the longevity of your HA injections:
Avoid touching or rubbing the injection site: This can help to prevent the HA from breaking down.
Avoid strenuous activity: Strenuous activity can increase blood flow to the injection site, which can break down the HA.
Protect your skin from the sun: Sun exposure can damage the HA and shorten its lifespan.
Moisturize your skin regularly: This can help to keep the HA hydrated and prevent it from breaking down.
Get regular touch-up injections: Touch-up injections can help to maintain the results of your HA injection.
