Many people with dark circles, hollow under-eyes, or a tired look choose to get Under-eye filler for a fresher appearance. However, this treatment requires proper care before and after the procedure. If you're planning to get Under-eye filler , this article will guide you on how to prepare, what to avoid, and how to choose a trusted clinic for the best results.

How to prepare for under-eye fillers and prevent bruising
You can follow your normal daily routine before getting under-eye fillers. However, if you're worried about bruising, it's best to avoid the following:
- Medications: Avoid painkillers, aspirin, and anti-inflammatory drugs (NSAIDs) for 2 weeks before treatment
- Supplements: Stop taking Vitamin E, Vitamin K, fish oil, and Primrose supplements for 2 weeks before treatment
- Alcohol: Avoid drinking alcohol for 24 hours before the procedure
Medications, supplements, and alcohol can increase blood circulation or slow down clotting. If the injection needle touches tiny blood vessels under the skin, it may cause bruising. However, this bruising usually fades on its own within 7-14 days and does not affect the effectiveness of the filler.

Post-treatment care for the best filler results
Under-eye fillers give instant results, but following the correct aftercare will help the filler settle properly and last longer.
- Drink plenty of water: Aim for 8-10 glasses a day—especially for the first 4 weeks after treatment. Fillers contain water-binding properties, so proper hydration helps them integrate smoothly with the skin.
- Avoid pressing or rubbing: Do not massage, press, or squeeze the treated area for one month to allow the filler to settle naturally.
- Avoid high heat exposure: Stay away from saunas, steam rooms, and laser treatments as high temperatures can break down fillers faster. However, you can still enjoy BBQ, hotpot, hair drying, and warm showers as usual.
- Manage discomfort: If you feel slight pain or tightness in your cheeks after the treatment, you can take Paracetamol for relief. These sensations will typically subside within 2-4 weeks.
How long do under-eye fillers last?
Results from Under-eye fillerlast 4-6 months. The filler is made from hyaluronic acid (HA), which retains moisture and hydrates the skin. Over time, it blends naturally with your under-eye area, reducing the appearance of dark circles and hollows while smoothing out fine lines.

How to choose a safe and trustworthy clinic for under-eye fillers
Taking care of yourself is important—but choosing the right clinic for your under-eye filler is even more important. A good clinic ensures both your safety and great results. Here are the key things to look for:
