Curious about breast enlargement pumps? We don’t blame you – these wonky-looking contraptions are among the safest, most effective breast enhancement methods there is. Plus, they come with the additional perk of being totally, completely non-hormone-affecting.

So if you’ve been wanting to try natural breast enhancement but don’t want to mess with your hormones – breast enlargement pumps provide a safe, side-effect-free, and effective option.

Here’s a brief overview on the most frequently asked questions about breast enlargement pumps.

How do breast enlargement pumps work?

Breast enlargement pumps operate through a process called tension-induced tissue growth. The concept is simple: By applying a gentle suction to the breast tissue, you’re essentially pulling your breasts. This stretching of the skin and tissue, when applied with even pressure and over time, stimulates new tissue growth causing your breasts to enlarge.

All breast enlargement pumps use the method of tension-induced tissue growth but the technology differs slightly from one to the other. The Brava system works by applying a gentle 3-dimensional pull to place the breasts under tension while the Noogleberry allows you to control how much pressure your apply to your breasts and for how long.

Both Brava and Noogleberry are sustained-tension systems, meaning that the suction pressure is applied to your breasts and sustained. Bosom Beauty, on the other hand, uses a sustain-and-release technology that automatically pulls and then releases your breasts throughout the entire session. Allegedly, this technique is 4 times more effective than systems that just sustained-tension methods since the motion increases blood flow and reduces the time it takes to get results.

At the same time, Bosom Beauty’s tension is pretty darn powerful and new users can find it painful. The varying technologies used by the different breast enlargement pumps and how they suit you is something you’ll want to take into consideration before you choose one

Are breast enlargement pumps safe?

There are a whole bunch of breast enlargement pumps on the market and many of them are simply not well-made. We don’t recommend these – and advise you to stay away from them – since shoddily made pumps can damage breast tissue and vessels, causing more harm than good.

As for the breast pumps we do recommend, if you use them as advised – they are perfectly safe. And by “using them as advised,” we mean not putting more tension on your breasts than is needed. This is not a risk you have to worry about with electric breast pumps like BRAVA – which is very safe and even doctor-recommended – and Bosom Beauty since the machine controls the amount of suction pressure on your breasts.

For manual, hand-operated devices like Noogleberry, however, you are in control and you need to be careful about how much suction power you’re giving your breasts.

Never pump so much that your breasts turn purple or feel like they’re going to “pop.” Aim to pump just enough so that you feel a pulling suction on your breasts and then keep that pressure constant.

How much growth can you get from using breast enlargement pumps?

It depends on the pump you’re using as well as how much you use it and how long you use it. Most of them average from between an increase of 1 to 2 cup sizes. Specifically, Brava users range between a ½ cup to 2 cup sizes of lasting growth. Bosom Beauty promises 1 to 2 cup sizes of permanent growth. And Noogleberry is also around 1 to 2 cups.

However, there is a lot of flexibility with breast enlargement pumps and that’s part of the reason we love them so much. Many users have gone beyond the 2-cup size increase with long-term use. And some users even combine one or two of the pumps to maximize gain.

Because these pumps enlarge breasts by applying constant, steady pressure – the results you get simply come down to how much and how long you use it. Again, in the end – how much growth you get from breast enlargement pumps really depends on how much time you’re willing to put in on a regular basis and for how long you’re willing to do that for.
