Hollow-looking areas and smile lines that seem deeper every year can make you look tired, even on days you feel rested. For many patients, old acne scars add to that uneven look, and both concerns often trace back to the same source: a gradual loss of collagen and support beneath the skin.
At Diamond Advanced Aesthetics in New York, NY, Bellafill is a medically supervised treatment we discuss with patients noticing this kind of volume loss. This article covers why facial hollowing develops, how Bellafill works, and why its results tend to last longer than temporary fillers.
What keeps Bellafill working for years after treatment?
Bellafill combines a collagen gel that adds immediate lift with tiny PMMA microspheres that stay in place as a support scaffold while your body builds its own collagen around them. Because those microspheres are not absorbed like temporary fillers, clinical data has shown results in smile lines lasting up to about five years, though individual results vary by patient and treatment area.
What Facial Hollowing Is and Why It Happens
Facial hollowing shows up as sunken or shadowed areas, deeper smile lines and a more tired or deflated look. It usually develops from a combination of changes beneath the skin:
- Gradual collagen loss, which leaves skin thinner and less supported
- Fat pads that shrink and shift lower over time
- Slow changes in facial bone structure
- Significant weight loss
Because these changes build slowly, many people first notice them in photos or under certain lighting. Smile lines and atrophic acne scars often become more visible at the same time, since both depend on the support beneath the surface.
How Bellafill Works to Restore Smoothness
Bellafill combines a smooth collagen gel with tiny polymethylmethacrylate (PMMA) microspheres. The collagen gel lifts the treated area right away, bringing a fold or scar closer to the level of the surrounding skin.
Over the following weeks and months, the gel is gradually absorbed while the microspheres stay in place as a support scaffold, and your body builds its own collagen around them. That combination is why many patients see smoother skin immediately and why results continue to hold. You can learn more about Bellafill in New York, NY and how it fits into a personalized plan.
Why Bellafill Results Last Longer Than Temporary Fillers
Hyaluronic acid fillers gradually break down over months, while Bellafill’s microspheres are not absorbed by the body. Clinical data has shown results in smile lines lasting up to about five years, though individual results vary.
That longevity is part of what makes it a biostimulatory filler procedure for long-term scar reduction and fold correction. It also means the treatment is less adjustable. Unlike hyaluronic acid fillers, Bellafill cannot be dissolved, so careful planning, conservative placement and an experienced injector are essential.
Where Bellafill Is Used and What Is FDA-Approved
Bellafill is FDA-approved for correcting smile lines (nasolabial folds) and moderate to severe atrophic acne scars on the cheeks in adults over 21. Smile lines are often one of the first places volume loss becomes visible, which is why many patients start there when reducing persistent smile line folds.
For acne scars, Bellafill lifts depressed areas closer to the surrounding skin, which may help with reducing persistent pitted acne marks and managing deep acne scarring on the cheeks. Patients looking for a treatment for acne scars and facial hollowing often ask if Bellafill can address both. Other hollow areas, such as the temples or under-eyes, fall outside its FDA-approved uses and are evaluated case by case, and your provider may recommend different dermal fillers in New York for broader volume concerns.
What to Expect From Bellafill Treatment
A typical treatment plan generally includes:
- A Good Faith Medical Evaluation, along with a skin test that may be done first to check for collagen sensitivity, since the gel contains bovine collagen
- One to two sessions for most patients, with lidocaine included in the product for comfort
- Aftercare guidance from your provider
Mild swelling, tenderness or bruising are common and usually short-lived, and most patients return to their routines shortly after. Less often, lumps or small bumps called granulomas can develop, which your provider will review with you. All injections are performed by licensed injectors under the direction of our Medical Director.
Who May Be a Good Candidate
A few common patterns describe people who tend to consider Bellafill:
- Adults with smile lines or atrophic acne scars who want longer-lasting correction
- People who have tried temporary fillers and prefer fewer repeat visits
Bellafill may not be right for people with a collagen allergy, a history of severe allergies or keloid scarring, or an active skin infection, and it is not recommended during pregnancy. For patients who want gradual, broader volume support, collagen stimulators may be part of the conversation. If you’re researching adult acne scar care in New York, NY, a consultation and evaluation is the best way to determine which option fits your concerns.
Frequently Asked Questions
Can Bellafill treat every type of acne scar?
Bellafill is approved for moderate to severe atrophic acne scars on the cheeks that soften when the skin is gently stretched, so deep, narrow scars may need a different approach, which your provider can determine during your evaluation.
What should I avoid after Bellafill treatment?
Most patients are advised to avoid strenuous exercise, heat and excess sun exposure for about 24 hours, and your provider will give you aftercare guidance for your treatment area.
Can Bellafill be combined with other treatments?
Bellafill can sometimes be part of a broader plan that includes other fillers, neuromodulators or skin treatments, with your provider recommending the timing and combination based on your evaluation.
Can I get Bellafill if I have had other fillers before?
Many patients who have used temporary fillers may still be candidates, though your provider will review your treatment history and timing during your Good Faith Medical Evaluation before recommending Bellafill.
