Why does weight loss influence nasolabial folds ?
The nasolabial fold is not strictly a wrinkle. It is a structural fold at the junction of the cheek's fat compartments (particularly the medial malar compartment) and the perioral region. With age or certain morphological factors, this line becomes more visible, deeper or even permanent. Its depth results from several mechanisms : skin density loss associated with intrinsic and extrinsic ageing, gradual midface tissue sagging, reduced bone support and subcutaneous fat, and repeated contraction of certain facial muscles.
Fat plays a central role in this process because it shapes facial volume. Any substantial weight change alters its distribution and visibly affects the nasolabial fold.
Does weight loss deepen nasolabial folds ?
Contrary to what might be expected, losing weight does not always rejuvenate the face. Substantial weight loss, even when desired and beneficial to general health, can age certain facial areas, particularly the temples, cheeks, dark circles and nasolabial folds.
Fat tissue is lost throughout the body. Superficial and deep facial fat compartments are also affected. Their reduction causes loss of cheekbone fullness, more prominent bony contours and collapse of tissues that supported the upper fold.
Midface volume loss therefore mechanically causes vertical sagging which, without good skin elasticity, accentuates the nasolabial fold. The face looks hollower and more drawn, and the fold becomes more visible, particularly when the skin fails to retract appropriately with weight loss.
Can weight loss reduce nasolabial folds ?
In some situations, moderate weight loss can positively affect the nasolabial fold. This mainly concerns young patients with skin that remains firm and toned, whose faces were initially very round. Reduced cheek fat then redefines contours, reduces pressure on the fold and consequently makes it less visible.
However, these cases remain exceptional. In most clinical situations, weight loss instead accentuates skin laxity, makes wrinkles more visible and removes the softness of facial curves, compromising overall aesthetic balance.
Does age influence the effect of weight loss on nasolabial folds ?
The patient's age decisively influences the effect of weight loss on the nasolabial fold. From 40, skin begins losing its natural elasticity. Its capacity to retract after weight loss declines markedly. In a patient aged 50 or 60, even moderate weight loss can therefore cause soft tissue laxity, increased wrinkles and more pronounced nasolabial folds and marionette lines.
More than weight itself, skin quality and the face's ability to retain volume determine how the nasolabial fold responds to weight loss. Young, thick, well-vascularised skin can adapt. Mature, thin or sun-damaged skin adapts less well and may reveal more wrinkles than before weight loss.
How can the face be preserved during weight loss ?
To limit the aesthetic impact of weight loss on the nasolabial fold, a gradual approach is recommended to give the skin time to adapt. Good internal and skin hydration is essential, as is sufficient protein and micronutrient intake, necessary for collagen production. An appropriate skincare routine incorporating ingredients such as retinol, peptides and antioxidants also preserves skin quality. Finally, in some cases, supportive gentle technologies such as radiofrequency, HIFU or mesotherapy may be considered to maintain skin tone throughout weight loss.
How can nasolabial folds be corrected after substantial weight loss ?
After substantial weight loss, particularly following bariatric surgery, facial changes are sometimes striking. The nasolabial fold can deepen quickly. When this causes significant distress, targeted aesthetic correction may be considered.
In this context, aesthetic correction may be considered. It is not limited to directly filling the fold, as this could weigh down features or produce an unnatural result. The doctor first restores missing volume, particularly in the cheekbones, then gradually refines treatment. This overall, consistent approach produces a harmonious result respecting each patient's facial structure.
Do weight fluctuations worsen nasolabial folds ?
Repeated weight fluctuations — typical of yo-yo dieting — are particularly damaging to facial structures. During each slimming phase, tissues partially retract ; with each weight regain, fat is redeposited, sometimes asymmetrically or unevenly. This alters facial architecture, causes chronic skin laxity and reduces natural volume definition. Nasolabial folds become more visible not only because skin sags, but because it gradually loses tissue memory. Over time, these fluctuations affect facial dynamics far more than stable excess weight, making fold correction more complex and less durable.
What do studies say about weight loss and nasolabial folds ?
Some studies have examined the relationship between fat mass and signs of facial ageing. An article published in Plastic and Reconstructive Surgery (2015) demonstrates that female patients losing more than 10 % of their initial weight after 45 show clearly accentuated nasolabial folds, cheek folds and jawline laxity. The study concludes that facial fat loss contributes to signs of ageing alongside collagen loss. Another publication in The Journal of the American Academy of Dermatology (2019) highlights that patients with naturally rounder faces retain a youthful appearance for longer. These data confirm that weight loss, although metabolically beneficial, must be accompanied by consideration of its aesthetic facial consequences, particularly for nasolabial folds.
