Answer:

Filler injections are a popular aesthetic dermatology method known for quickly improving depressed areas, especially mild pitted scars. For shallow pitted scars on the cheeks and under the chin, as you described, this method can help achieve a fuller and more even skin surface in a short period.

Filling pitted scars involves injecting a dermal filler, typically hyaluronic acid (HA), into the skin layer beneath the scar. When precisely placed, the filler lifts the scar base to align with the surrounding skin, simultaneously enhancing moisture and elasticity, resulting in smoother skin immediately after treatment. Beyond providing an instant filling effect, HA also retains water and stimulates endogenous collagen production.

However, filler effectiveness largely depends on the scar type. This method is most suitable for mild to moderate pitted scars, particularly shallow boxcar scars and rolling scars with a wavy surface. For deep, narrow scars like ice pick scars, fillers typically cannot achieve complete correction and require combination with other techniques, such as TCA cross or microneedle radiofrequency (RF).

Hyaluronic acid fillers are biodegradable within the body. On average, the scar-filling effect can last 6-12 months, depending on individual physiology, injection site, the type of filler used, and post-treatment skincare. To maintain results, repeat injections are necessary as advised by a doctor.

Advantages of filler injections include minimal invasiveness, quick procedure time, and almost no downtime. Patients might experience mild reactions such as swelling, redness, or bruising at the injection site for the first few days. However, this is a medical procedure demanding high skill. Improper execution, incorrect injection depth, or the use of substandard products can lead to complications like lumps, infection, or even vascular occlusion. Therefore, it is crucial to choose a reputable medical facility with a qualified dermatologist or cosmetic dermatologist to ensure safety.

Beyond fillers, doctors may recommend combining them with other technologies, such as laser treatments, microneedle radiofrequency, or subcision, to optimize effectiveness, especially for long-standing scars.
