Inverted Nipples - What Options Are There to Correct Hollow Nipples?

When the nipples point inward instead of naturally protruding, it can be unsettling - in everyday life, in intimate moments, while breastfeeding, in how you feel about your own body. So-called inverted nipples, or retracted nipples, are not uncommon. They occur in varying degrees and can affect women of any age. Some of these breast malformations are congenital, others only appear later in life.

What matters is this: today there are safe, modern, and individually tailored ways to correct inverted nipples - with an eye toward naturalness, sensitivity, and a result that feels right for you. At BRST in Zurich, we combine thorough diagnostics with gentle corrections to achieve a naturally protruding, natural-looking nipple. Arrange a personal appointment and let us guide you with care.

What are inverted nipples?

Inverted nipples refers to one or both nipples (mamillae) being retracted, either not protruding outward at all or only temporarily. Many women experience this breast malformation primarily as an aesthetic concern; depending on severity, functional aspects can also play a role, such as difficulty breastfeeding or recurring local irritation. In particularly pronounced cases, this is also referred to as "hollow nipples".

Inverted nipples should be distinguished from flat nipples. With flat nipples, the nipple does not project beyond the areola. This is considered a variant of the normal shape and should not be confused with inverted or hollow nipples, where the nipple is actually pulled inward.

Inverted and hollow nipples: grades and differences

Inverted nipples present in three typical grades:

• Grade 1: In mild cases, the nipple temporarily protrudes with cold, touch, or gentle traction, then retracts again afterward.
• Grade 2: Moderate retraction can be manually drawn out, but it doesn't stay in place.
• Grade 3: With a hollow nipple, the nipple remains permanently inverted and barely responds even to stimulation.

Which grade applies is determined during an examination, and this forms the basis for the recommendation of conservative or surgical steps.

Causes: why do inverted nipples develop?

Several factors can play a role in the development of inverted nipples. The most common cause is an anatomical characteristic.

• Congenital characteristics of the milk ducts and connective tissue Shortened milk ducts or taut connective tissue strands are often present, pulling the nipple inward. This anatomical variant is often present since puberty and is usually medically harmless - but depending on its severity, it can be perceived as aesthetically bothersome.
• Hormonal phases: puberty, pregnancy, menopause Hormonal changes affect tissue elasticity and glandular volume. As a result, a previously mild retraction can become more pronounced or become visible for the first time. Many changes during these phases are reversible - a specialist assessment provides clarity.
• Inverted nipples with age With increasing age, tissue tension decreases, connective tissue becomes firmer or thinner, and the nipple can shift further inward. This development is common, but should be evaluated if it appears newly and without an identifiable cause.
• Scars and scarring after inflammation or procedures Local inflammation, abscesses, or previous surgeries can lead to scars that pull the nipple inward. In such cases, a targeted, gentle correction can help release the tension and reshape the nipple stably outward.
• Functional causes related to breastfeeding and care During breastfeeding, irritation, minor injuries, or recurring inflammation can change the tissue. Good care and early treatment of any issues help prevent scarring; where retraction already exists, we advise on sensible options.
• Trauma, pressure, or piercings Less commonly, external factors such as repeated pressure, injuries, or piercings trigger changes in the connective tissue that pull the nipple inward. An individual medical history helps identify such triggers and plan the appropriate treatment.
• Rare conditions - warning signs with newly occurring retraction If a previously normal nipple suddenly retracts without a clear reason, this should be medically assessed. Rare causes such as inflammatory processes or - very rarely - breast-gland-related conditions must be reliably ruled out.

Is breastfeeding possible with inverted nipples?

Breastfeeding is often possible with mildly inverted nipples, especially when flat nipples predominate and the nipple protrudes with stimulation. Good breastfeeding preparation, guidance from a lactation consultant, and, if needed, nipple shields that make latching easier can all help.

With pronounced hollow nipples, breastfeeding is more difficult, because the baby has a harder time latching onto the nipple. In these cases, a targeted correction - conservative or surgical - can improve the starting point. An individual assessment before a planned pregnancy is important, so that options and limitations can be discussed realistically.

Do inverted nipples also occur in men?

Inverted nipples can also occur in men, caused by shortened connective tissue strands. In most cases, it is purely a cosmetic matter, though occasionally irritation or inflammation can occur, as secretions can build up in the retracted area. A small, targeted correction is possible for men as well, and is planned based on symptoms and the wish for a more harmonious appearance.

Can I correct inverted nipples myself?

If inverted nipples appear for the first time or change suddenly, this should first be assessed by a doctor. This allows us to rule out rare but relevant causes and to assess which conservative steps make sense.

• Nipple shields (shells) worn under clothing Flat plastic shells apply gentle, even pressure to the areola and can gradually train the nipple outward. These are best suited for mild retractions and need to be worn regularly over several weeks. Expectation: often improvement, but not always permanent.
• Suction devices/niplettes for temporary negative pressure Small devices create brief suction and draw the nipple outward. With consistent use, the effect can stabilise, though the relapse rate varies depending on severity. Skin care and breaks are important to avoid irritation.
• Manual techniques and gentle massage Regular, careful stretching at the junction of the nipple and areola can make the tissue more supple. Benefits and limitations vary individually; care, hygiene, and patience are key. Pain, redness, or cracked skin are a signal to stop.
• Nipple shields as support for latching Nipple shields can make suckling easier when the baby has difficulty grasping the nipple. They do not permanently correct the retraction, but they improve function during breastfeeding. A lactation consultation helps with correct use.
• Piercing for inverted nipples A horizontally placed piercing can mechanically "fix" the nipple in its everted position, making it harder for it to retract. Advantages include immediate visibility and a potentially stabilising effect; risks include infection, irritation, pressure pain, and scarring. This option should only be considered after professional assessment, in a hygienically impeccable studio, and with close follow-up care.
• Taping/protective caps for short-term stabilisation Soft caps or skin-friendly adhesive strips can temporarily support the everted nipple. This is suitable as a transitional solution, but does not replace permanent therapy. Skin tolerance and regular changing are important.

When does treatment for inverted nipples make sense?

What matters most is how much this affects you personally - regardless of how pronounced the retraction appears from the outside. If you feel unsettled by how it looks, have trouble breastfeeding, or experience recurring irritation, a correction of inverted nipples can make sense.

Together, we review conservative options and discuss whether and when a surgical correction is medically sensible, safe, and realistic. A small, targeted procedure can release the structures pulling the nipple inward and shape it into a permanently everted position - with a discreet incision and clear information about sensitivity and breastfeeding ability.

Modern treatment options for hollow nipples

If the retraction is moderate to severe, or conservative measures don't lead to a stable result, we recommend a surgical correction. The goal is a natural shape with sensitivity preserved as much as possible.

We gently release the structures pulling the nipple inward through a small, discreet incision. Depending on your individual situation, a technique can be chosen that preserves the milk ducts as much as possible, to maintain breastfeeding ability. The procedure is usually performed on an outpatient basis under local anaesthesia or a short sedation, and recovery is typically quick.

Short-term protective caps stabilise the new position; swelling and bruising subside within the first few days. We advise individually on activity, taking a break from sport, and scar care, so the result stays stable over the long term.
