Correct pectus excavatum
without surgery.
You know the routine. The shirt that stays on. The arms crossed in photos. The only fix anyone offered was a metal bar or learning to live with it. There is a third way, used in hospitals for twenty years, and you can do it at home.

- Dry the chest completely. Cool room, bone-dry skin. Wipe the chest and dry it fully, with no oil, lotion or sweat, because damp skin under the rim raises fluid pockets.
- Center the bell over the dent. Lie back. Center it over the deepest point, hose toward the top of the breastbone, rim on the firm edge of the dent, sides pressed in gently.
- Pump it to max. Squeeze until no more air comes out (300 millibar), then hold 255 to 300. A hard pull is normal; pain that stays or skin that breaks means stop and see a doctor.
- Hold until the dome sits level. Watch through the clear dome until the whole surface sits level, about 30 minutes for a moderate chest. Holding longer only adds bruising.
- Release the valve, then lift. Open the valve and let the pressure equalize before the bell comes off. Never pull it off under suction.
- A red ring is normal. A ring of redness that settles inside the hour is normal, and so is bruising over the following weeks. A dark, black bruise means stop and see a doctor.
- Gel over the whole ring. Spread the sodium hyaluronate hydrogel over the whole ring while the skin is warm. It cools and hydrates the skin the bell just worked, so it stays calm and ready for tomorrow's session.
- Brace on within a minute. Shoulder straps first, then pull the waist straps snug. The session lifted the breastbone, and the brace holds it there for the other 23 hours.
Why it works
The cartilage, the muscles that pull the breastbone back, and what the hospital studies measured.
Read the scienceNot everyone qualifies. You’ll know in 60 seconds.
It works on a chest that still moves, a mild to moderate dent that lifts under suction. Age changes how long it takes, not whether it works; the Swiss series’ oldest patient was 61 (Basel cohort). For a deep, rigid dent it is the wrong tool, and we would rather say so now than take your money.

The bell isn’t why people fail. Stopping is.
In a 115-patient study, people with structure and someone checking on them kept going 83% of the time, against 58% alone (Haje et al., 2021). Not a better device. Someone watching. So every bell ships with the method written down and a person who did this checking on you.
Sized to you, checked twice.
Checked by a person before it ships.

Yours the moment you finish the quiz.
Guidance and support, free.
A plan and check-ins every 2 to 3 weeks.
The brace, optional add-on.
Holds the position between sessions.
The gel, optional add-on.
So your skin never stops the routine.

What the surgery involves.
A metal bar behind the sternum, two to three years, then a second operation to take it out. $40,000 to $80,000. It is a real option, and for some chests the right one. For a chest that still moves, there is a way to find out first.

Built by someone who did it.
Tomas Titus had pectus excavatum. He spent close to a year in the research first: every pectus study, the vacuum bell papers, the surgical literature, the biology of cartilage, the physics of a seal. Then he built one routine for speed and ran it on himself, filmed every morning. A one-inch dent to nearly flat in four and a half months, where published cohorts take 12 to 24. That routine is the guide, and he still answers every message.
What the evidence shows.
of studied patients improved significantly (Basel cohort, about 140 patients).
adherence with structured support (Haje et al., 2021).
patients in peer-reviewed research on the therapy (27 studies; Sesia et al., 2025).
Each dot is 10 patients.

Can Exercise Fix Pectus Excavatum?
No exercise moves the breastbone on its own. One exercise helps keep it where a vacuum bell puts it.

Questions people ask before they start.
Does it hurt?
Expect firm pressure, not pain, and temporary marks in the first weeks. Stop signals, every time: pain that stays after the bell comes off, skin that breaks rather than marks, or fluid pockets; pause use and see a doctor.
How many hours a day?
Twice a day from day one, morning and evening, at least 3 to 4 hours apart. Each session runs until the surface under the dome sits level, capped at 30 minutes, never longer.
Will it come back?
The bell lifts the breastbone into position in one session and the brace keeps it there the other 23 hours, so the cartilage learns the position over months. Long-term follow-up data is limited, which is why the protocol includes monthly progress reads and every order carries the 90-day money-back guarantee.
Is there an age limit?
No. Age changes how long it takes, not whether it works. Children and adolescents respond fastest because their cartilage is softer, and the oldest patient in the Swiss series was 61 (Basel cohort).
What if it does not work for me?
