Aiyoh, panau memang annoying lah, especially when it spreads to arms and tummy! Honestly, a few of us mums tried various creams from pharmacy, but panau is tricky because it comes back if you don't keep the area dry and cool, so make sure you're not sweating too much in that area, wear loose cotton clothes when you can, and dry properly after shower. Best to check with your doctor or dermatologist to confirm it's panau and get the right treatment, because if it's something else it won't work meh, and they can give you something stronger if the over-the-counter stuff isn't cutting it.
