The nasolabial fold is one of the most common facial wrinkles, often associated with an expression of fatigue or severity. Present in everyone, it tends to deepen gradually with age through skin ageing, volume loss and muscle dynamics. Many patients wonder about the ideal time to intervene : should they wait until the fold is very visible ? Can treatment be preventive ? Is there a recommended age from which treatment becomes appropriate ?
There is no universal answer, because this decision depends less on age than on a precise assessment of each patient's facial structure, anatomy, dynamics and aesthetic objectives. Nasolabial fold treatment forms part of an overall harmonisation approach that considers gradual tissue ageing and the patient's personal expectations.
At what age does the nasolabial fold appear ?
The nasolabial fold lies between the cheek and upper lip, marking the transition between the malar area (cheekbones) and perioral region. It is a static and dynamic fold that deepens through several combined factors : midface fat compartment sagging, reduced dermal density associated with intrinsic ageing, repeated contraction of the upper lip elevator muscles, bone loss in the upper jaw, and ligament and skin laxity.
Although the nasolabial fold can appear from childhood as an expression fold, over the years it becomes a true sign of ageing. At this stage, it reflects a lasting structural change. Treatment must therefore aim to restore missing volume, support lax tissues and soften the transition between different facial areas.
From what age should a nasolabial fold be treated ?
There is no universal age, but in practice initial nasolabial fold treatment is generally considered between 35 and 45, depending on the patient's facial structure, skin quality and lifestyle. Before 35, pronounced folds are rare except in particular cases : a very slim face, hereditary fold, substantial weight loss, excessive sun exposure or premature skin ageing.
The appearance of the nasolabial fold does not depend solely on age. It often indirectly results from malar ptosis – descent of the cheekbones – and gradual volume loss. Rather than focusing on the fold itself, the doctor must therefore analyse the whole face and determine whether restoring cheek or temple volume would be a more consistent, lasting approach.
Can the nasolabial fold be treated preventively ?
Increasing numbers of patients, often from their thirties, seek advice when a nasolabial fold appears. It remains subtle but becomes perceptible in raking light or certain photographs. At this early stage, the aim is not to correct an established wrinkle, but to act preventively to preserve volume harmony and avoid gradual disruption of skin planes.
The approach relies on small injections of lightly cross-linked hyaluronic acid chosen for its suppleness and hydrating capacity, potentially combined with a Skinbooster. The aim is not to fill the fold or change facial structure, but to maintain dermal thickness, stimulate collagen production and slow the development of early signs of ageing.
This treatment requires great precision. Overly pronounced correction risks weighing down the face or freezing its expression. This is why a preventive approach must be entrusted to an experienced doctor capable of performing the procedure accurately and respecting each patient's natural facial structure.
Nasolabial fold treatment between 35 and 45
This is the age range in which nasolabial fold treatment most frequently becomes indicated. The fold becomes more visible, sometimes even at rest, and the face begins to lose a little tone. At this stage, targeted, measured correction restores a rested appearance while respecting natural facial expression.
Treatment generally involves moderately cross-linked hyaluronic acid with good cohesivity. The technique varies according to need : linear retrograde injection with a cannula, or microboluses, depending on fold depth. If cheekbone projection has been lost, subtle midface restoration may also be offered to address overall facial harmony.
Should a nasolabial fold be treated after 50 ?
After fifty, the nasolabial fold most often reflects overall laxity of facial structures. In this context, an isolated injection directly into the fold risks weighing down the area without correcting the actual cause of hollowing. A more structural approach is then required, beginning with restoration of bone and fat support points through non-surgical lifting techniques before considering targeted fold treatment at a later stage.
For these patients, injections are frequently spread across several sessions. This staged progression allows the face to adapt gently and ensures a more balanced, natural and harmonious result.
Why is a consultation essential before treating a nasolabial fold ?
Whatever the age, the treatment decision is made during the initial medical consultation. This must include : three-dimensional facial analysis, assessment of the patient's expectations (prevention, rejuvenation, harmonisation), a study of facial mobility, and presentation of different treatment options with their indications, contraindications, effect durations and costs.
The doctor must also clearly explain that nasolabial fold treatment does not necessarily mean complete disappearance of the fold, but harmonious softening that respects facial movement.
Is biological age more important than actual age ?
The concept of the face's biological age is increasingly valued. It relies on an overall facial assessment (skin, volume, tone, symmetry, expression) and establishes a personalised treatment plan independent of chronological age.
A patient aged 34 may have facial tone loss equivalent to that of a patient aged 45 because of particular genetics, a demanding lifestyle or associated conditions (hormonal disorders, oxidative stress). Conversely, some people retain a perfectly firm face with few signs of ageing until 50.
It is therefore biological age — rather than the patient's actual age — that guides the appropriate time for nasolabial fold treatment.
At what age should a nasolabial fold be treated in women and men ?
The age at which nasolabial fold treatment becomes appropriate also varies with the patient's sex. Compared with men, women generally have thinner skin and smaller bone structure, meaning the nasolabial fold can appear from their thirties. Hormonal fluctuations associated with the menstrual cycle, pregnancy or menopause also directly influence dermal collagen quality.
In men, the dermis is thicker, the facial skeleton larger and subcutaneous tissues denser. Folds therefore often appear later, but can quickly deepen when ageing accelerates (around 45-50). Treatment indications must be adapted to skin type, lifestyle and the aesthetic expectations specific to each sex.
Can a nasolabial fold be treated too early ?
Treating nasolabial folds early, sometimes from twenty-eight or thirty, may be justified in certain situations. However, intervening too early or without a genuine indication carries risks. It can cause localised overfilling if selected volumes do not match a still-young face's anatomy, or unattractive rigidity when the gel is too cross-linked for supple, elastic skin. In some cases, injection can also alter natural facial dynamics by hindering expressions, or encourage psychological dependence in very young patients particularly focused on their image.
In this context, the doctor's role is decisive. They must know when to refuse an unnecessary injection, reassure patients by directing them towards more appropriate care such as skin treatments, preventive measures or lifestyle and dietary advice, and offer injections only when genuinely indicated.
What is the average age for a first nasolabial fold injection ?
According to a retrospective review published in Journal of Cosmetic and Laser Therapy (2020), the average age for a first hyaluronic acid injection into the nasolabial fold is 41,6 in women and 46,3 in men. The study also shows that 22 % of patients start before 35, 47 % between 36 and 45, 31 % after 46.
These figures confirm that aesthetic need is most often felt between 35 and 45, but that a growing proportion of younger patients are motivated by prevention. Other studies, particularly those published in Aesthetic Plastic Surgery, highlight earlier demand in urban populations exposed to social pressure around appearance, with injections sought from the early thirties.
