Smile line injection (filler or botox) is one of the modern cosmetic methods, helping to fill wrinkles, rejuvenate the face and bring a fresh, radiant appearance. However, to achieve the highest aesthetic effect and maintain long-term results, post-injection care – especially diet – plays a very important role. Many seemingly harmless foods can make fillers difficult to shape, cause inflammation or slow down the recovery process. So what to avoid after smile line injection? Let’s find out with HBIO Clinic in the article!

Top 5 foods to avoid after smile line injection

What to avoid after smile line injection is always a concern for many women, below are 5 foods you should avoid:

1. Sticky rice (sticky rice, banh chung, sweet rice pudding …)

Foods made from sticky rice are hot, easily cause swelling and inflammation in the injection area. In addition, sticky rice also prolongs the healing process, making the filler injection area more susceptible to bruising. Therefore, you should avoid it completely for at least 1–2 weeks after your smile line injections.

2. Chicken and Beef

Chicken and beef are rich in protein, and while they are healthy, they can easily cause dark or raised scars at the injection site. Some people also experience itching and discomfort after eating these two types of food.
It’s best to avoid them initially so that the skin can recover faster and have a more even tone.

3. Seafood (shrimp, crab, fish, squid, etc.)

Seafood is a food group that easily causes allergies in many people. When the body is recovering after filler injections, seafood can stimulate an inflammatory reaction, causing swelling, redness, or itching at the injection site. Those with sensitive skin should especially avoid it to minimize risks.

4. Water spinach

Water spinach contains substances that stimulate excessive collagen production, making the injected area prone to keloid scarring or asymmetry. This vegetable should be absolutely avoided not only after filler injections but also in most other beauty treatments or dermatological surgeries.

5. Alcohol, stimulants, and spicy foods

Alcohol, coffee, carbonated soft drinks, and spicy foods all cause blood vessels to dilate, increasing the risk of bruising and bleeding under the skin. At the same time, fillers are harder to stabilize and are more easily rejected, affecting the aesthetic results.

What Foods Should You Eat After Getting Smile Line Injections?

What should you eat after getting smile line injections to both improve your health and help your skin recover quickly? Here are some food groups recommended by experts:

1. Foods Rich in Vitamin C

Vitamin C plays a crucial role in stimulating the body to produce natural collagen – the main factor that helps skin become firm and elastic. After smile line injections, supplementing with foods rich in vitamin C such as oranges, tangerines, grapefruits, kiwis, strawberries, or bell peppers will help heal tissues faster and reduce bruising and swelling in the injection area. Not only that, vitamin C also helps boost the immune system, limiting the risk of infection during the recovery process.

2. Foods Rich in Easily Digestible Protein

Protein is an essential building block for regenerating and restoring skin cells after injections. Instead of eating fatty red meat that can easily cause inflammation, you should prioritize easily digestible protein sources such as chicken, fish, eggs, tofu, yogurt, or fresh cheese. These foods provide energy and help regenerate skin tissue quickly without burdening the digestive system, thus helping the body stay healthier during the healing process.

3. Green vegetables and fruits rich in fiber

Green vegetables and fresh fruits not only supplement vitamins and minerals but also provide plenty of fiber essential for the digestive system. After injections into smile lines, maintaining a healthy digestive system will help the body absorb nutrients better, thereby increasing the effectiveness of recovery. Some vegetables such as broccoli, carrots, spinach combined with fruits like apples, pears, bananas… are ideal choices to detoxify the body, prevent constipation, and help skin look healthy and radiant.

4. Foods rich in omega-3

Omega-3 is a type of unsaturated fatty acid known for its anti-inflammatory properties and ability to support skin regeneration. After injecting fillers for smile lines, you should supplement foods rich in omega-3 such as salmon, mackerel, herring, chia seeds, flax seeds or walnuts. They not only help reduce swelling, redness and bruising but also improve skin moisture and elasticity, helping to maintain aesthetic results longer.

5. Foods rich in zinc and vitamin E

Zinc and vitamin E are both nutrients that support cell regeneration, heal damage and protect the skin from free radical attacks. You can add almonds, cashews, pumpkin seeds, whole grains or spinach to your daily menu. These foods will help strengthen the immune system, shorten recovery time after injection and give you healthy, youthful skin.

6. Drink enough water and natural smoothies

Water plays an important role in purifying the body, maintaining skin moisture and supporting nutrient transport. After smile line injection, you should drink 1.5 – 2 liters of water per day to keep your skin supple, limit dryness and support rapid healing. In addition, juices or smoothies from fresh vegetables and fruits such as oranges, pineapples, carrots, celery or watermelon are also great sources of vitamins and minerals for the body.

Laugh line filler injection is one of the modern cosmetic methods, helping to reduce wrinkles, improve sagging and bring a youthful, radiant appearance. To achieve optimal results, this process is usually performed in the following steps:

Step 1: Examination and consultation

First, the doctor will conduct a general examination of the face, assess the level of smile line folds as well as the skin structure. From there, the doctor will come up with a personalized treatment plan: the appropriate filler type, the amount of filler to inject, and the expected results. This is an important step for you to understand the entire process and have realistic expectations.

Step 2: Prepare the injection area

Once the plan is agreed upon, the injection area will be thoroughly cleaned to ensure sterility. The doctor often uses anesthetic cream or a light anesthetic injection to minimize discomfort. Careful preparation helps you feel secure and comfortable throughout the procedure.

Step 3: Proceed with filler injection

The doctor uses a specialized needle or cannula (blunt needle) to inject the filler into the correct position of the smile line. This process only takes about 15-30 minutes, is gentle and quick. Most customers only feel a slight numbness, completely within the tolerance range.
