Lume Deodorant | Outrageously Effective Whole Body Deodorant

It’s time for another honest conversation as we tackle one of women’s many universal truths: under breast sweat—aka underboob sweat, aka SWOOB, aka mountain dew.

If, like me, you sweat buckets under your breasts, girl, know that you’re not alone! Underboob sweat is totally normal, expected, and (here’s the good news) controllable.

Let’s review why it gets so sweaty under the breasts and how Lume makes it easy to deal with underboob sweat.

Why Do We Sweat So Much Under Breasts?

Our bodies are covered in sweat glands to help keep us cool. So, to all my fellow Sweaty Betties out there, feel free to tell your high school friends that, yes, you did indeed stay cool.

The area under the breasts doesn’t have more sweat glands than other areas, but it gets extra sweaty because our breasts create natural skin folds. This is particularly true for those of us who can hold a pencil or really tuck anything under there for safekeeping. Skin-on-skin contact creates heat, triggering the body’s natural thermoregulation system to cool down by sweating.

When you add things like humidity, exercise, tight clothing, or bras that don’t allow airflow, you’ve created the perfect storm for underboob sweat. And that can also lead to underboob sweat smells.

Add hormones to the mix and life events like pregnancy, postpartum, perimenopause, and menopause, and it just gets sweatier.

And what’s more, some of us won the sweaty genetics lottery, and it’s just a nuisance we have to deal with throughout life. If you can relate, you know why I say that gray and light blue shirts have simply been OFF-LIMITS!

There’s no better way to grow the size of sweat marks on clothes than feeling anxious about sweat marks on clothes. It’s rude but true.

The Problem With Sweating Under There

Too much moisture + movement + skin-to-skin contact can create a few problems, some annoying, and some downright uncomfortable.

Moisture—Sweat marks, especially under your boobs are more of a badge of honor when you are at the gym or on a long run, but most of us aren’t really looking to advertise underboob sweat in everyday social situations.

Odor—Sweat leads to odor, that’s just basic science. Bacteria living on our skin consume bodily fluids on our skin and create odor. The odor reaction is the same whether is it in our armpits, underboobs, privates, or feet.

Our bodies have two kinds of sweat glands: apocrine and eccrine. Eccrine sweat is mostly water and unlikely to cause odor. On the other hand, apocrine sweat has a higher pH and includes fat and proteins. Odor causing bacteria LOVE it! Apocrine sweat glands are found in areas like our armpits, genitals, belly buttons, and nipples, which is why these zones are most likely to get smelly.

Irritated Skin—When excessive moisture is trapped between skinfolds and you add friction, the top layer of skin can get rashy and break down. This skin condition is called intertrigo and it causes redness, itching, and, in some cases, inflammation. Bacteria and yeast can really thrive in this environment. Our bras just hold that moisture in, making matters worse.

What’s a Girl To Do About The Girls?

Dress to For Success

You will benefit from whatever you can do to create a better underboob ventilation system. The right bra can play a big role in helping with underboob sweat by improving airflow and reducing friction.

Bras made from breathable, moisture-wicking materials (like cotton, bamboo, or sports fabric) allow air to circulate better, which helps keep the skin under your breasts cool and dry. This is key for preventing sweat buildup.

A bra that fits well and provides support, without being too tight, reduces the amount of skin-to-skin contact, which is one of the main causes of underboob sweat.

Hygiene the Lume Way

If you’ve got the right product, you can control the sweat that is the catalyst for all the other problems. Lume’s got the remedy for boob sweat and odor. Our premium washes, deodorants, and wipes all contain Mandelic Acid - a gentle alpha hydroxy acid that is pH optimized to control odor and support skin.

START IN THE SHOWER

Keep the area under the breasts clean. Lume Acidified Body Wash and Acidified Cleansing Bar are clinically proven to remove odor better than soap, and to control odor for 24 hours. These aren’t just ordinary washes—they’re highly functional and as gentle as water on your skin.

Our washes are clinically proven to brighten dark spots, help fade scars, visually even skin tone, and decrease the appearance of hyperpigmentation.

GET REALLY DRY

The secret to sweat rash prevention is to start off completely dry. Let everything air out a bit after showering. You can even use a hairdryer on a low heat setting to make sure you are nice and dry before applying underboob deodorant.

DEODORANT + SWEAT CONTROL

Lume Whole Body Deodorant plus Sweat Control is clinically proven to control odor and sweat for 72 hours. Start with a pea sized amount and rub in under the breasts—it’s safe to use anywhere you have odor and sweat but wish you didn’t.

You will be noticeably drier when using Lume Deodorant plus Sweat Control, and you’ll love how it rubs in like a lotion with no residue on skin or clothes.

TOUCH UP BETWEEN SHOWERS

Lume Acidified Deodorant Wipes are clinically proven to control odor for 24 hours. Keep them on hand and swipe underboob, under skinfolds, and undercarriage between showers or whenever you need a little refresher. Keep a pack in your gym bag, carry on, or desk drawer and touch up on the go.

Where Else Can You Use Sweat Control?

Pits and underboobs aren’t the only places that get sweaty. Ever notice the hourglass-shaped sweat marks in your underwear? Apply Lume Deodorant plus Sweat Control to thigh folds and under butt cheeks, and you’ll be noticeably drier.

At the end of the day, underboob sweat is a completely natural thing. We all deal with it and there should be no stigma around addressing the topic. So, arm yourself with the right tools and the best practices. And stay cool 4 ever, ladies. Stay cool.
