The GoodSweat journal
Sweat is good. Ditch the cover-up.
A field guide for people who want less underarm theater: sweat-positive science, deodorant residue, and cosmetic ingredient literacy.
Three pillars
Start with the right frame.
01
Sweat Is Good
Sweat is normal physiology, not a personal failure. Learn the difference between cooling, stress, and the skin chemistry around odor.
02
Leave The Layer Behind
Sticks, sprays, fragrance cover-ups, laundry shadows, and the daily residue people were taught to accept.
03
Octenidine + odor-binding minerals
A plain-English ingredient desk: Octenidine HCl, zinc glycinate, and what a rinse-off underarm cleanser can say responsibly.
First reads
Where to start.
Start here if you want the GoodSweat point of view in order: founder essays, category maps, sweat literacy, ingredient history, and the practical body notes around underarms.
Six years without deodorant
A founder essay on moving underarm care into the shower and leaving the stick behind.
Antiperspirant vs. deodorant vs. underarm cleanser
Three categories, three jobs: sweat reduction, cover-up, and rinse-off underarm care.
What is Octenidine?
The molecule, cosmetic cleanser context, and responsible product language.
Eccrine vs. apocrine sweat glands
A clear map of cooling sweat, stress signals, and why underarms behave differently.
The hot tub
The messy, human start of underarm care that moved into the shower.
Octenidine vs. chlorhexidine
Two different molecules, different histories, and why product context matters.
Why octenidine became familiar in Europe
European pharmacy shelves, public records, and ingredient labels made the name familiar.
Why stress sweat feels different
Different body signals, different glands, and a calmer way to read nervous underarm sweat.
Babies sweat. Underarm odor usually comes later.
Baby sweat, puberty chemistry, and why familiar underarm odor usually arrives later.
I quit deodorant six years ago
What changed, what stayed normal, and why underarm care moved into the shower.
A calmer first deodorant talk
A practical way to explain kids' first body odor without making the body the problem.
Why gym shirts smell worse than bodies
Fabric, sweat, oils, laundry history, and the shirt side of the odor loop.
Whole-body deodorant and odor anxiety
Why a booming category says as much about smell anxiety as it does about scent.
The underarm microclimate
Warmth, folds, fabric, glands, and the little weather system under a shirt.
How sweat becomes underarm odor
The underarm chemistry that turns quiet secretions into noticeable odor.
Fragrance fatigue and underarm care
When fresh gets too loud, shared air and underarm care need a quieter routine.
Extreme heat is changing your shower routine
Hotter days, useful sweat, fabric timing, and the cleaner reset after heat.
ABCC11, earwax, and underarm odor
Gene variation can explain odor precursors without ranking bodies or routines.
What sweat actually does
Sweat cools the body. Detox is mostly organ work, not sauna theater.
Sensitive underarms are still skin
Underarms are folds, friction, fragrance, shaving, fabric, and skin first.
What happens between shower and shirt
The tiny timing window where clean skin, fabric, residue, and scent meet.
Perimenopause night sweats and the morning shower
Heat at night, a practical reset by day, and no moral cleanup story.
After the cold plunge
Bathhouses, contrast therapy, and the quieter ritual of heat, cool, rinse, rest.
Hyperhidrosis, sweat volume, and odor
Excessive sweating, clinician-side options, and why volume and odor need different tools.
Armpit hair and odor, explained
Hair is normal. It can still change moisture, residue, and how easily skin rinses clean.
When reapplying deodorant stops helping
Reapplying can help in a pinch. Clean skin still starts with a rinse.
How garlic relates to body odor
Food can nudge body scent. Breath, skin, underarms, and shirts need different care.
One molecule, one mineral
Octenidine HCl and Zinc Glycinate, kept in cosmetic cleanser context.
Why stress sweat starts in your hands
Heat sweat starts at your scalp; stress sweat goes straight for your palms, soles, and underarms. Why nerves pick those spots first.
The point
Less cover-up. More body literacy.
GoodSweat is building a cleaner underarm category, one article at a time: respect sweat, name the cover-up, and explain the tools without turning the bathroom into a lab.
