Why smile lines deepen
Smile lines deepen mainly because the cheek above them loses support. The nasolabial fold is the boundary where the cheek meets the upper lip. When the cheek is full and well supported, that boundary is a soft crease. When cheek volume drops, tissue slides forward and down onto the boundary, and the crease turns into a deep fold.
Anatomy research explains why. In a cadaver study of facial fat compartments, Rohrich and Pessa showed that the nasolabial fat is a discrete compartment and that the cheek fat above it is made of three separate compartments. Those compartments change at different rates with age, so the cheek does not deflate evenly and shearing between them adds to the fold.
Bone matters as well. A review of aging changes in the facial skeleton found that the midface skeleton, particularly the upper jaw beside the nose, tends to resorb with age. Less bone under the cheek means less scaffolding for the soft tissue above the fold.
Signs it is a cheek problem, not just a line
Many men who ask about their smile lines are really seeing cheek deflation. These clues point that way:
- The fold is deep at rest, not only when you smile.
- The cheekbones look flatter than they did in photos from ten years ago.
- A shadow runs from the side of the nose toward the corner of the mouth.
- Pressing the cheek gently upward and outward in the mirror makes the fold soften noticeably.
- Under-eye hollows or early jowls have appeared at the same time.
If the fold barely changes when you lift the cheek, the crease itself is the main problem and treatment can focus there. Related patterns are covered on our pages about hollow under-eyes and jowls.
Causes beyond age
Age sets the pace, but other factors speed it up:
- Weight loss, especially large or rapid loss, which empties the cheek compartments
- Sun exposure, which breaks down collagen and thins the skin
- Smoking, which damages collagen and blood supply to the skin
- Genetics and bone structure, since a flatter midface shows folds earlier
- Endurance training at very low body fat, which can leave the face looking gaunt
Men who have lost a lot of weight on semaglutide or tirzepatide often notice deeper folds within months. Our page on facial volume loss after GLP-1 weight loss covers that situation.
How the fold is assessed
Assessment looks at the whole midface, not just the crease. The nurse injector studies your face at rest, smiling and talking, from the front and both sides, and checks cheek projection, skin thickness and how the fold responds when the cheek is supported.
You will be asked about blood thinners, fish oil and other supplements that raise bruising risk, previous filler, cold sores, autoimmune conditions and allergies. Photos are taken so changes can be judged fairly at follow-up.
Some findings change the plan. An active skin infection or cold sore near the mouth means waiting until it clears. A history of severe allergic reactions, a bleeding disorder or recent facial surgery is discussed before any product is chosen, and in some cases filler is not the right step at all. Men who grow a mustache or beard should mention how they wear it, since facial hair changes how much of the fold shows day to day.
Treatment order: cheek support, then the fold
The approach that avoids an overfilled look treats the cause first. Filling a deep fold on its own can push the upper lip area forward and make the lower face look heavy, which tends to look less natural on men.
| Step | Product | Purpose |
|---|---|---|
| 1. Cheek support | VOLUMA XC, placed deep on the cheekbone | Lifts and supports the tissue that was sliding onto the fold |
| 2. Reassess | No product | See how much of the fold remains once the cheek is supported |
| 3. Fold refinement | A small amount of RADIESSE or a softer hyaluronic filler | Softens the remaining crease without bulk |
The products have FDA approvals that match these roles. VOLUMA XC was approved in 2013 for deep injection to correct age-related volume loss in the midface. RADIESSE was approved in 2006 for moderate to severe facial wrinkles and folds, such as nasolabial folds.
Durability depends on the product and the area. The American Academy of Dermatology gives typical ranges of 4 to 12 months for hyaluronic acid gels and 6 months to 1 year for calcium hydroxylapatite, and longevity also shifts with the area treated and your own metabolism. Plan on maintenance rather than a one-time fix.
Reversibility differs. Hyaluronic acid fillers such as JUVÉDERM and VOLUMA can be dissolved with hyaluronidase if needed, while RADIESSE cannot. Our answer on whether dermal filler can be dissolved explains when that matters. For deeper detail, see cheek filler for men, nasolabial fold filler and our comparison of JUVÉDERM and RADIESSE.
Emergency signs after filler
The skin beside the nose has a rich blood supply, which is why careful technique matters here. The FDA lists unintended injection into a blood vessel as the most serious filler risk, with possible tissue death, vision problems and stroke.
Call 911 or go to the ER for any vision change, severe pain out of proportion to a normal injection, skin on the nose, lip or cheek that turns pale, blotchy or dark, facial droop, or trouble breathing with swelling of the lips or tongue. Ordinary swelling and small bruises are expected and fade over several days.
How Ultimate Male treats smile lines
Ultimate Male treats smile lines through a consultation at our San Gabriel or Downey clinic, booked after a free 10-minute phone call. Aesthetic nurses Sabrina Sher and Paul Pham plan the cheek-first approach with you and show you in the mirror where each product would go.
Because cheek support alone can soften the fold noticeably, the plan often starts there and adds fold treatment only if a crease remains. Product amounts are decided face to face rather than quoted in advance. Treatment with dermal fillers is direct-pay, and CareCredit, Prosper Healthcare Lending and Afterpay offer ways to finance it. Smile-line filler is cosmetic, so it is generally not an FSA or HSA expense.
