This is a guide to filler compiled by Dr. Choi Byeong-geun of SHINE U Clinic Konkuk (3 minutes' walk from Konkuk Univ. Station, Exit 1).
Filler is a procedure that adds volume to desired areas without surgery, making it relatively accessible. However, even if it seems simple, post-procedure care determines the results. We have organized precautions by item for safe and satisfactory results.
Why is aftercare important?
Hyaluronic acid filler is relatively low-risk because if you don't like the shape, it can be dissolved and adjusted. Nevertheless, care until it settles determines the shape.
The shape that settles can vary depending on how you manage it immediately after the procedure.
Do not touch the treated area
Applying strong pressure to the injected area can deform its shape. It takes time for it to settle, so please observe the following:
- Do not press or massage with your hands.
- Avoid sleeping face down.
- Avoid excessive exercise for a while.
- For nose filler, refrain from wearing glasses or sunglasses.
Avoid high-temperature environments for one week
Filler is sensitive to temperature, so it is recommended to avoid high-temperature places such as saunas, jjimjilbangs (Korean bathhouses), and hot yoga for one week after the procedure.
No alcohol or smoking for one week
Alcohol and tobacco can cause inflammation, so please avoid them for one week. If your immunity decreases due to lack of sleep or overwork, the likelihood of a reaction may increase, so managing your condition is also important.
Ask when you're confused about filler aftercare
Bruising and swelling are natural processes
Bruising or swelling may occur after the procedure. Swelling usually subsides within 1-2 days but may last longer in some cases, and bruising occurs when the needle touches a blood vessel and takes time to disappear.
A blunt-tipped cannula is mainly used to reduce bruising, but the recovery may vary from person to person.
Things to check before the procedure
- Confirm that genuine products and the correct amount are used.
- Choose a filler suitable for the area and skin type.
- Have the procedure performed by experienced medical staff.
Each type of filler has different duration and characteristics. If performed excessively, inflammation may occur, so it is important to inject accurately at the appropriate depth.
Conclusion
As this is a cosmetic procedure, thorough prior consultation about your preferred shape and areas of concern is essential for satisfactory results. Results may vary from person to person, so please proceed after careful consultation.
