Advantages of filler injections to treat concave scars
Fast, visible results after 1 injection
Fillers immediately fill in the concave areas of the skin, especially effective with shallow concave scars such as rolling or boxcar scars.
For example: After 1 injection session, the cheek area with many concave scars will look significantly flatter and smoother, helping you feel more confident right away.
Simple procedure, less painful, no need for long recovery
The procedure only takes about 30-60 minutes, you can go home the same day.
There may only be slight swelling or bruising at the injection site, which will disappear within 2-3 days.
Quick beauty before an important event
If you have a wedding, photo shoot or important event, fillers help improve your skin quickly without having to wait long. Unlike lasers or microneedling that require recovery, fillers are very convenient for the “last minute”.
Can be combined with other therapies to optimize effectiveness
For example: With long-standing deep scars, the doctor can combine filler injection with subcision technique (cutting the bottom of the scar) or fractional laser to soften fibrous tissue and increase collagen regeneration.

Disadvantages of filler injections to treat concave scars
The effect is not permanent, the filler gradually dissolves after 6-12 months
The HA filler is gradually absorbed by the body, you need to re-inject periodically if you want to maintain smooth skin.
For example: You inject filler to fill concave scars in January, by October-December the skin area will start to show concave scars again.
Not effective for all types of concave scars
Ice pick scars (needle scars, very small and deep) are often difficult to completely fill with filler, requiring other specialized methods. If the filler is injected in the wrong layer, the filler can create roughness, making the skin uneven.
Requires a highly skilled doctor to avoid dangerous complications
Injecting filler requires placing the needle in the right layer under the skin, avoiding blood vessels to avoid blockage or skin necrosis. If injected incorrectly, it can cause clumping, filler displacement, or severe inflammation and swelling.
The cost is quite high and requires periodic injections
A filler injection to treat concave scars can cost from 5-15 million VND depending on the area and type of filler. If you want to maintain long-term effectiveness, you will need to spend more money on subsequent injections.
Risks of using fake fillers or injections at an unreliable facility
Using fillers of unknown origin can cause allergies, infections, or other serious complications. You need to choose a clinic, a doctor with a practice license, and use genuine fillers with safety certification.

So can filler injections treat all types of acne scars?
Not necessarily. The effectiveness depends on the type of scar and the extent of skin damage:
- Most effective for shallow acne scars with soft edges and a round base like rolling scars or mild boxcar scars.
- Less effective for ice pick scars (deep and narrow needle-shaped scars), because these scars are often deep under the skin, making it difficult for fillers to reach accurately.
- Areas of skin with contracted scars and long-standing fibrotic tissue may need to combine other methods such as subcision (cutting the bottom of the scar), laser, or PRP for better results.
How long does the effect last?
- Usually lasts from 6 to 12 months, depending on the type of filler and each person’s constitution.
- After this time, the filler will gradually dissolve, and if you want to maintain the results, you need to re-inject periodically.
