Folds trap sweat and moisture, so moms stress keeping the area dry; many heal it with Sudocrem, Siloderm, B4 Nappi, Dermadew or coconut oil, but recurring fold rashes can be eczema and several were diagnosed and prescribed creams by a doctor.
⚠️ Caution:If a fold rash keeps coming back despite drying and creams, or spreads to other folds (behind the knees, elbows), see a doctor - it may be eczema or fungal and need a prescribed cream; avoid powders and steroid creams (like Valbet or Candid B) except on medical advice.
Parents get worried and discouraged when a fold rash that cream healed before suddenly won't respond, fearing something more serious. The community reassures that trapped sweat is the usual culprit and keeping folds dry plus a barrier cream usually works, while honestly noting that persistent fold rashes are often mild eczema - common in the first year and very manageable with a doctor's prescribed cream.
Here's what moms in our community shared based on their own experience.
Sudocrem applied for a few days healed it for one baby; Siloderm also worked, and some use Siloderm first then B4 Nappi.
Dermadew diaper rash cream worked well on a daughter's neck rash.
Apply coconut oil and keep the area diaper/fold-free and dry as much as possible.
Use a prescribed medicated powder like Candid (not random powder) - takes 2-3 days.
Vaseline petroleum jelly worked specifically for irritated underarm/skin folds in a young baby.
It can simply be sweat trapped in the folds, which need to be kept dry.
If it's from milk dribbling, Lactocalamine helped.
Recurring fold rashes were diagnosed as eczema by a pediatric dermatologist (common until age 1) - keep the area dry, apply a prescribed cream like Atogla or Valbet, and don't use powders as they can aggravate it.
