What usually changes in the face in this phase
After 40, the change that draws the most attention is not the wrinkle. It is support. The face is still the same one, but the way support is distributed across the thirds of the face starts to shift, and that changes how light falls on it.
Midface
The malar region, the cheekbone area, is where the face usually loses support first. When it deflates and descends, the midface flattens and the under-eye hollow looks deeper, even without any change in the eyelid skin.
Lower third
With the midface sitting lower, the nasolabial fold deepens and the jawline loses definition. It is the classic concern of someone who looks at a profile photo and feels the line of the face is no longer the same.
Skin and texture
The skin becomes a little thinner, produces less collagen and creases more easily. It responds well to care, but it does not restore the support that comes from the deep layers.
Why 40 comes up so often in this conversation
Loss of support usually becomes visible between the ages of 35 and 50. It is not a line crossed on a birthday. It is the moment when several slow changes add up enough for the mirror to show them.
Underneath, three things happen at once. There is gradual bone resorption in areas such as the orbit, the cheekbone and the jaw, so the base everything rests on shrinks. The fat compartments of the face change: some deflate, others descend. And the skin produces less collagen, following movement less well.
The pace of all this is personal. Genetics, sun, sleep, smoking and large weight fluctuations explain why two women aged 42 can be at very different points. The number on the document says little; what the assessment finds says a lot.
What the assessment looks for
The facial assessment does not start with the complaint, it starts with the whole. Using photos and an analysis of the thirds, the goal is to separate what has lost structure from what only looks tired. That distinction is what prevents treating the wrong place.
The diagnosis also takes your moment in life into account: routine, health, what genuinely bothers you and what you do not want changed in your face. Some faces need structure before anything else, and some faces do not need anything yet. If it does not make sense to apply anything that day, nothing is applied.

Which options exist without surgery
Each option works on a different layer, and the choice depends on what the assessment finds:
- Hyaluronic acid: restores structure at the deep support points. It is the option that responds directly to loss of support.
- Botulinum toxin: acts on the muscles of expression, as part of facial planning, not as an isolated procedure.
- Microfocused ultrasound: a technology used when the assessment indicates it, always within a plan.
The indication changes from face to face. Skincare at home still counts, but it does not restore deep structure. If your main concern is the face descending, also read why the face sags and which treatments can help.
How the N3F® Protocol works with this phase
In the N3F® Protocol, the whole face is treated in the same session, with hyaluronic acid only, in three steps and always in this order.
Structural replacement
Structural replacement restores the volume that time took away, at the points that support the face. It is the foundation of the plan.
Repositioning
In repositioning, what has descended regains a higher position. This is the step that demands the most anatomical reading, and it is where the lifting effect comes from.
Enhancement
Enhancement closes the design: the features that have always been yours, slightly more defined, without excess. The natural look comes from that order, not from a finish applied at the end.
What happens after the session
After 40, facial rejuvenation makes more sense as follow-up than as a single event. The path after the restructuring has two milestones: a 60-day follow-up for fine adjustments, with everything settled, and annual maintenance, with about a third of the initial amount, adjusted to your moment.
Because the foundation has already been built, the logic is to work with less product at each visit. This is what Dr. Fred Fortes calls management of aging: planned recurrence instead of one-off decisions taken whenever something bothers you.

Care that still matters at home
No in-office treatment replaces the basics, and the basics weigh more than they seem in this phase:
- Sunscreen every day. Unprotected exposure accelerates photoaging, the most consistent external factor.
- A guided skincare routine, which improves skin quality: texture, glow and the ability to hold water.
- Sleep and alcohol in moderation, because morning puffiness changes how the face reads.
- Avoiding large weight fluctuations, which disorganize the fat compartments of the face.
The assessment takes place at N3F Clinic, in Brooklin, São Paulo, or during periodic appointments in Florianópolis.
