Aw, ang hirap talaga ng insect bite marks na tumatagal, lalo na sa baby's sensitive skin! Honestly, for dark spots from bites, I'd check with your pedia first kasi basta-basta lang hindi safe lahat ng creams for babies, some of my mum friends nag-try ng vitamin E oil or silicone-based scar creams pero kailangan pa rin ng doctor's go-ahead, especially if matagal na ang marks. In the meantime, sunscreen talaga ang life-saver namin to prevent them from getting darker, kaya pati bite marks protected from the sun.
