Hello. I'm Kim Joo-won, the head director of Melon Plastic Surgery, your breast specialist.

There are times when you feel your upper breasts are sunken when wearing clothes or a bra. This feeling of the upper part of your breasts suddenly disappearing, which you usually took for granted, is often experienced after dieting or childbirth.

Most people only realize the significant impact upper breast volume has on their upper body line after noticing that their upper breast volume has decreased.

Naturally, when the bust line becomes flat, you feel as if your body's balance is broken, which can lead you to seek medical attention.

‘Can exercise refill sunken upper breasts?’‘Are there any improvement methods other than breast surgery?’

Today's topic is upper breast hollowing. We will discuss the causes of upper breast hollowing, exercises that help prevent it, and surgical improvement methods.

Upper Breast Hollowing | Causes and Key Factors

Upper breast hollowing refers to a state where the area above the areola and below the collarbone, i.e., the upper part of the breast, appears sunken or flattened.

Although it is a change that occurs in many women, upper breast hollowing has a considerable impact on appearance. If you usually stick to tight fashion, or enjoy tight tops with baggy bottoms, the visible upper breast hollowing can be quite noticeable.

What are the causes of upper breast hollowing?

Biological causes include aging and weakening of Cooper's ligaments. After the mid-20s, collagen and fat decrease, at which point Cooper's ligaments, which support the breasts, stretch, and the volume in the upper part also gradually diminishes.

Life changes can also be a cause. After pregnancy and childbirth, breasts rapidly enlarge and then rapidly shrink. In this process, the fat layer decreases, often leading to the hollowing of previously full upper breasts.

Rapid weight changes are also a cause of hollowing. The upper body has a higher proportion of enzyme receptors that break down fat.

Have you ever heard people say that when you lose weight, your breasts are the first to go? This is somewhat true. When body weight decreases due to dieting, breast volume also decreases, and the upper breasts, in particular, have a thin fat layer, so even a small loss can make them appear noticeably hollow.

Finally, there can be congenital causes. If you have naturally less breast tissue or a long rib cage, your upper breast volume may appear smaller.

Upper breast hollowing is a natural change that happens to everyone. If you are aware of it and manage it proactively, it is possible to maintain beautiful breasts for a longer period.

Upper Breast Hollowing | Can Exercise Improve It?
‘Can upper breast hollowing be improved with exercise?’‘If exercise can't improve it, are there other methods?’

Exercise can help prevent upper breast hollowing and delay its onset, but it does not achieve complete restoration. Since breasts have a higher proportion of fat and glandular tissue than muscle, even intense exercise will not refill lost volume.

Nevertheless, upper breast exercises contribute to breast elasticity. Exercises like push-ups, dumbbell flyes, and chest presses stimulate the upper pectoralis major muscle, helping to maintain a firm bust line and tighten it if it has sagged.

To maximize the effectiveness of exercise, it is good to wear a functional bra. A sports bra that minimizes breast movement during physical activity is helpful.

An ill-fitting bra can weaken Cooper's ligaments and also cause breast sagging. It is recommended to regularly measure your breast size, including your rib cage.

Exercise helps prevent upper breast hollowing but does not completely stop it. Its significance lies in slowing down the rate of breast hollowing and maintaining elasticity.

Also, consume enough protein and water, and get sufficient sleep. Healthy habits for your body greatly contribute to maintaining breast elasticity.

Upper Breast Hollowing | Surgical Methods for Noticeable Improvement?

If upper breast hollowing does not improve with exercise alone, then surgery can be considered.

When surgery aims to restore upper breast volume, the approach varies depending on the degree of hollowing. If the hollowing is not severe, volume restoration may be possible with implant insertion alone.

On the other hand, if there is moderate to severe hollowing or if the overall glandular tissue is also sagging, a lift procedure (mastopexy) may need to be combined to raise the sagging tissue and correct the upper volume.

The scope of a lift procedure, or breast lift, varies depending on the degree of skin laxity (sagging) and nipple position. For Stage 1 sagging, a lift suitable for minor sagging may be performed. For Stage 2-3 or higher sagging, a lift to improve significant sagging may be necessary.

As with any surgery, sufficient communication with the medical team is paramount for breast surgery. By clearly understanding your condition through dialogue and finding the most appropriate surgical method with your medical team, you can regain a voluminous and beautiful bust line.

Upper Breast Hollowing | Choices for Beautiful Breasts

Upper breast hollowing is a natural process that eventually occurs to everyone. Therefore, it is important to accurately understand your condition and choose the appropriate method.

Exercise helps with prevention and maintaining elasticity, while surgery can provide definite improvement. If there is no change despite consistent exercise, and sagging worsens, it may be time to seek help from a medical professional.

Although hollowing is a natural change, if left unmanaged, both elasticity and volume will gradually decrease. Manage consistently, regularly check your condition, and consult your doctor when you feel that self-care is no longer sufficient.

We will listen attentively to any breast concerns you have and accompany you on your surgical journey.

Thank you.
