As we age, skin loses elasticity and sags, so not only the face but also the skin on the breasts can sag, leading to breast drooping. Because of this, it is easy to think that skin sagging only happens as you get older.
But did you know that there are main causes of breast sagging that even women in their 20s should be careful about?
Breast sagging in women can occur for various reasons, but if breast sagging appears at a young age, there may be certain causes behind it. Today, let’s look at the main causes of breast sagging that can affect women in their 20s as well.
What causes breast sagging in young women?

There are many causes of breast sagging in women. Among them, for young women in their 20s, the reasons breast sagging appears may include the following. It is a good idea to check whether any of these apply to you.
- Rapid dieting
Many young women may set a rapid weight-loss plan to manage their figure. However, this can affect breast firmness. When weight loss happens quickly, the fatty tissue in the breasts may decrease first, and the skin and Cooper’s ligaments may not adapt to the sudden change, causing them to lose elasticity and become stretched.
- Wearing the wrong bra size
For young women, wearing a bra that is the wrong size can also be a cause. In particular, when wearing a bra that lacks support during exercise, continuous stress is placed on the breast tissue and Cooper’s ligaments, which can lead to breast sagging.
- Genetic factors and skin characteristics
The density of skin tissue and breast tissue can vary depending on genetic influence. Skin elasticity, collagen production ability, and breast tissue density can all be affected by genetic factors. If these factors are weak, breasts may sag earlier even at a young age.
- Lack of exercise
Lastly, there is a lack of exercise. If the chest muscles are weak, they cannot properly support the breast tissue, which lowers skin elasticity and can easily lead to breast sagging.
How to self-check for sagging breasts

So far, we have looked at the causes of breast sagging in young women. Then how can you tell how much your breasts have sagged? It is best to assess the degree of sagging through a medical professional’s diagnosis. But if you want a simple check at home, you can use the following self-check method as a rough reference.
🔍 Simple self-check method
-
Take off your top and stand straight in front of a mirror.
-
With your arms naturally lowered, observe the shape of your breasts from the front and side.
-
Check the relative position of the nipple and the inframammary fold.
🎯 If the nipple is above the inframammary fold, there is no sagging or only a mild degree of sagging.
🎯 If the nipple is at the same height as the inframammary fold: it can be considered stage 1 breast sagging.
🎯 If the nipple is slightly below the inframammary fold: it can be considered stage 2 breast sagging.
💦 If the nipple is significantly below the inframammary fold and points downward: it can be considered stage 3 breast sagging.
Gangnam-gu breast sagging surgery methods

So far, we have looked at the causes of breast sagging and the self-check method for sagging breasts. Surgery for sagging breasts, or breast ptosis, can vary depending on each individual’s degree of sagging, skin elasticity, breast size, and the direction in which they want improvement.
- Periareolar incision
This is a suitable method when the amount of breast volume to be removed is small and there is no need to significantly raise the nipple position. Because the incision is left only around the areola, there is less concern about scarring and recovery time is easier to shorten.
- Vertical incision
This is a suitable method when the breasts are also wide from side to side. It is difficult to move the nipple position, and because the incision does not extend along the inframammary line, there is less concern about scarring.
- Anchor incision
This method is used when a large amount of breast volume needs to be removed and the nipple position must be raised significantly. Compared with other methods, there is more concern about scarring, but effective reduction and shape improvement are possible.
Closing

So far, we have looked at breast surgery methods. Improving sagging breasts requires a customized approach, considering the causes and degree of sagging for each individual. Even after surgery, careful management is necessary to help lower the risk of side effects.
In everyday life, poor posture can place unnecessary strain on the chest muscles and ligaments, so it is good to try to maintain proper posture. In addition, combining this with exercises that strengthen the chest muscles may help prevent breast sagging.
