Chafing 101: How to Prevent and Treat It, According to a Dermatologist
What Actually Causes Chafing
Chafing happens when skin repeatedly rubs against skin, fabric, or damp material, breaking down the outer skin barrier and leaving behind raw, stinging, and sometimes burning irritation. It shows up most often on the inner thighs, underarms, bra line, groin, and feet, and it gets worse quickly with heat, sweat, and movement. This is exactly why it becomes such a common complaint in summer.
Left alone, chafed skin does not just stay uncomfortable. Continued friction can lead to:
- Raw, cracked, or bleeding skin
- Scarring or dark spots, also known as post-inflammatory hyperpigmentation
- A higher risk of infection, since chafed skin is compromised skin
- Flares of underlying conditions like eczema or folliculitis
The fix is not complicated: create a barrier between the skin and whatever it is rubbing against before friction has the chance to build.
What to Look for in an Anti-Chafe Product
Not every “anti-chafing” product actually holds up to a full day of movement and sweat. A few ingredients consistently show up in the ones that work:
- Emollients like coconut oil, grapeseed oil, and shea butter, which soften and hydrate the skin
- Occlusives like petrolatum and dimethicone, which physically block friction
- Zinc oxide, a barrier ingredient also found in mineral sunscreen and diaper rash cream
- Soothing extras like aloe, vitamin E, and allantoin, which calm skin that is already irritated
- Fragrance-free formulas, since added fragrance is one of the most common irritants on already-sensitive, friction-prone skin
Texture matters too. A good stick or balm should glide on smoothly and leave a barrier that lasts through sweat, water, and hours of movement, rather than something that rubs off within the hour.
Best Anti-Chafe Sticks and Balms
Body Glide
Body Glide is a long-standing favorite for anyone dealing with chafing during exercise, travel, or simply a hot, humid day. The formula creates a strong, waxy barrier that holds up well even during intense activity.
- Body Glide For Her Anti-Chafe Balm: A thicker, wax-like barrier that is a good fit for bathing suit lines, bra straps, or the back of a shoe. It works well anywhere that needs heavy-duty, long-lasting protection.
- Body Glide Original Anti-Chafe Stick: The unisex original is easy to toss into a gym bag or carry-on. It works well anywhere skin meets skin or fabric, including under running gear.
Megababe
Megababe built its whole brand around solving “taboo” body issues like thigh chafing, and its Thigh Rescue stick is one of the most dermatologist-recommended options available. The formula tends to glide on with a smoother, less waxy feel than some competitors.
- Megababe Thigh Rescue Anti-Chafe Stick: Formulated with grapeseed oil for hydration, along with aloe and vitamin E for soothing. It applies in a deodorant-style stick, making it fast and mess-free for on-the-go reapplication.
Gold Bond
Gold Bond’s Friction Defense Stick is a well-known drugstore option that dermatologists often point to as an affordable, effective alternative to pricier balms.
- Gold Bond Friction Defense Stick: Contains zinc oxide and aloe leaf extract to create a barrier while calming already-irritated skin. It is unscented and non-greasy, so it layers well under clothing.
- Gold Bond Body Powder: A classic option for keeping skin dry in areas prone to sweat-related chafing, such as the groin or underarms.
Quick Tips for Preventing Chafing
- Apply a chafe stick or balm to clean, dry skin before activity starts, not after irritation begins.
- Reapply after swimming, heavy sweating, or several hours of activity.
- Choose moisture-wicking fabrics over cotton for workouts or hot days.
- For already-irritated skin, a plain barrier ointment like petroleum jelly can help it heal while a chafe stick prevents new friction.
When to See a Dermatologist
Most chafing resolves on its own once friction stops and a barrier product is added to the routine. See a dermatologist if the irritation does not improve within a few days, looks infected, or keeps recurring in the same spot despite prevention. Signs of infection may include increasing redness, warmth, swelling, or pus. Recurring irritation can sometimes point to an underlying skin condition that requires a different approach.
