In short
- The reference is not the cup size or your age: it is the inframammary fold. Everything is measured by comparing where the nipple is with that crease.
- Grade 1 (mild): the nipple is level with the fold.
- Grade 2 (moderate): the nipple is below the fold, but it is not the lowest part of the breast.
- Grade 3 (severe): the nipple is below the fold and it is the lowest part of the breast, pointing at the floor.
- 🔑 And there is a fourth scenario that is not ptosis: pseudoptosis. The nipple is still level with the fold or above it, but the tissue has fallen below it, with a nipple-to-fold distance that is usually more than 6 centimetres.
- ⚠️ An implant does not lift the nipple. It fills the breast; it does not reposition the nipple-areola complex.
- And the evidence backs that up: in a prospective series of 784 cases, ptosis persisted in 9.5% of the patients after breast surgery.
- 🔴 The grade is determined by measuring, in consultation and standing up. It cannot be self-diagnosed from a photograph.
“My breasts have dropped” describes a feeling, not a diagnosis. In plastic surgery the dropping of the breast —breast ptosis— is measured, has grades and rests on a single anatomical reference: the inframammary fold, the crease where the breast meets the chest wall.
Knowing which grade you are in is not a curiosity. It is what determines whether surgery is needed, which one, and what scar you are going to have.
This page explains how the droop is classified. What the surgery that corrects it does, with which scars, risks and price, is in breast lift without implants in Valencia.
The reference: the inframammary fold
Before the grades it is worth understanding why this line is used and not another.
The inframammary fold is the crease where the breast rests on the chest wall. It is a relatively fixed anatomical structure: it does not rise or fall with your bra size, or with your clothes, or with the posture in the photograph. That is why it works as a stable reference.
What does move with the years, with pregnancies, with breastfeeding and with changes in weight is the contents of the breast and the nipple-areola complex, which descend relative to that line.
⚠️ Two practical consequences. The first: the measuring is done standing up, because lying down the breast shifts and the nipple-to-fold relationship stops meaning anything. The second: a photograph of you is not enough — the real distance from the sternal notch to the nipple and from the nipple to the fold has to be measured.
What is measured at the assessment
The classification by grades is a guide, but the real assessment is done with a tape measure. Three things are measured here:
| What is measured | What it is for |
|---|---|
| Distance from the sternal notch to the nipple | It places the nipple on the chest, not only relative to the fold. It is the measurement that says how far it has to be raised |
| Width of the base of the breast | It defines the real space available, and it determines the technique and —if one is used— the implant |
| Pre-existing asymmetries | There are almost always some, and if they are not measured beforehand, they are put down afterwards to the surgery |
🔑 The third is the one it is most worth knowing exists. The two breasts of the same person are rarely identical, and an asymmetry that was already there shows up much more once you have spent weeks looking at yourself in the mirror. Measuring it and showing it to you before surgery is what avoids that conversation afterwards.
⚠️ All of this is measured standing up: lying down, the breast shifts and the distances stop meaning anything.
The three grades
The classification used all over the world is Regnault’s, and its logic is simple: it looks only at where the nipple is.
| Grade | Where the nipple is |
|---|---|
| 1 — mild | Level with the inframammary fold. |
| 2 — moderate | Below the fold, but not the lowest part of the breast. |
| 3 — severe | Below the fold and it is the lowest part of the breast. |
Translated into what you see in the mirror:
Grade 1. The breast has lost firmness and the upper pole has emptied, but the nipple still faces forwards. It is the grade in which there is most doubt about whether to operate and in which most options fit.
Grade 2. The nipple has crossed the line of the fold. It is usually the moment when clothes stop sitting as they did and when a bra goes from being a choice to being a necessity.
Grade 3. The nipple is the lowest point of the breast and points downwards. It is the grade in which the excess skin is greatest and in which the scar pattern will almost certainly be the most complete one.
Pseudoptosis: when the breast drops but the nipple does not
This is the scenario that causes most confusion in consultation, and it deserves a section of its own because the surgery it needs is a different one.
In pseudoptosis, the nipple is still level with the inframammary fold or above it, but most of the breast has clearly fallen below it. That is: the tissue has gone downwards and the nipple has stayed up, facing forwards or even slightly upwards. It usually comes with a nipple-to-fold distance of more than 6 centimetres.
It is a typical pattern after breastfeeding and after losing weight: the breast empties at the top and the contents gather in the lower pole.
🔑 Why the distinction matters. In a true ptosis the problem is that the nipple has dropped and it has to be raised. In a pseudoptosis the nipple is where it should be and the problem is the distribution of the tissue and the excess skin of the lower pole. Confusing them leads to proposing the wrong operation.
Why an implant does not lift the nipple
It is the question asked most often —“wouldn’t implants alone be enough for me?”— and the answer deserves to be explained, not dismissed.
An implant adds volume. It fills the breast, gives some projection back to the upper pole and, in a mild ptosis, can give the impression of having lifted because it tightens the skin from inside. What it does not do is move the nipple-areola complex: if the nipple was below the fold, it will still be below the fold, only on a larger breast.
And there is a figure that backs this up. In a prospective evaluation of 784 procedures published in 2013, ptosis persisted after surgery in 9.5% of the cases. It is the complication that appears when volume is added without correcting the position.
⚠️ That said, this page does not decide for you. Whether an implant suits you, whether a lift on its own suits you or whether both do depends on how much volume you are missing, how much skin is left over and what you want, and it is set out in the corresponding section of the guide to breast lift without implants. All that is explained here is why the grade of ptosis is not corrected with volume.
What the grade does NOT decide
For the sake of precision, three things that tend to be put down to the grade of ptosis and do not depend on it:
It does not decide whether you need implants. That depends on the volume you have and the volume you want, not on how far the breast has dropped. You can have a grade 3 and need no implant at all.
It does not decide your final cup size. A breast lift repositions the tissue; it does not remove it. If there is excess volume as well, the procedure that applies is a different one —it is in breast lift or breast reduction?—.
It is not a question of age. Ptosis is associated with ageing, with large breasts, with weight loss, with pregnancy and with hormonal changes, but there is no age at which it is “due”. There are grade 2s at thirty and firm breasts at sixty.
And does the grade change over time?
Yes, and in one direction only. The skin goes on losing elasticity, gravity goes on acting and every pregnancy, every period of breastfeeding and every large swing in weight leaves its mark.
That does not mean there is any hurry to have surgery. It means two more useful things:
- That the grade you have today is not the one you will have in ten years’ time, and it is worth bearing in mind when deciding when.
- That surgery does not freeze the clock either: recurrence of ptosis is among the described complications of the procedure. It is dealt with in second breast lift.
🔑 And this practice’s answer to “should I have surgery now?” is clear: there is no grade beyond which not waiting is recommended. Ptosis is never an emergency. The surgery is done for aesthetic reasons or because of discomfort, and neither of the two carries any risk to life, so the moment is yours to choose.
⚠️ Be wary of anyone who tells you otherwise. That the grade advances with the years is a piece of information for deciding when, not a reason to hurry you — and haste, in surgery you choose to have, is a poor adviser.

Frequently asked questions
How do I know what grade of ptosis I have?
By comparing, standing up, where your nipple is relative to the inframammary fold: level with it is grade 1; below it but not the lowest part of the breast, grade 2; below it and the lowest part, grade 3. The reliable measurement is done in consultation, not from a photograph.
When is a breast considered to have dropped?
When the nipple has reached or passed the line of the inframammary fold. Above that line one does not speak of ptosis, even if the breast has lost firmness.
What is pseudoptosis?
A breast in which the nipple is still level with the fold or above it, but the tissue has fallen below it, with a nipple-to-fold distance that is usually more than 6 centimetres. It is common after breastfeeding and after weight loss, and it is not corrected in the same way as a true ptosis.
Would implants be enough for me instead of a lift?
An implant adds volume but does not reposition the nipple. In a prospective series of 784 procedures, ptosis persisted after surgery in 9.5% of the cases. Whether one, the other or both suit you is decided by the volume you are missing and the skin left over, not by the grade.
At what age is it best to have a lift?
There is no recommended age. Ptosis is associated with age, with pregnancy, with breastfeeding, with changes in weight and with the size of the breast, but the grade does not go by years: what is assessed is your anatomy, not your date of birth.
Will a lift take me down a cup size?
That is not its aim: it repositions the volume that is there, it does not remove it. If there is excess volume as well, the procedure indicated is a different one.
Can the areola be reduced in the same operation?
The areola falls within the design of the lift, so its size is adjusted in the same procedure. How much and how is part of the individual plan.
Will my breasts drop again afterwards?
The result is not permanent: recurrence of ptosis is among the described complications. The skin goes on ageing, and weight, a pregnancy or breastfeeding can change it.

Book your consultation
If you have come here looking for which grade you are in, the home check is a single one: standing up and facing the mirror, look at whether your nipple is above, level with or below the crease where the breast rests on your chest. That places you.
What that check does not tell you is what you need, because that also depends on the volume you have, the skin left over and what you want to achieve. For that, measuring is needed.
