Effective bug repellant for baby? Pati mabilis na pamalis ng scar and dark marks due to insect bites

I've tried contra bug of unilove and gone away lotion of tiny buds pero ganon pa din, may kumakagat kay baby na insect and nakakafrustrate kasi sobrang alaga naman namin pero ganon pa din talaga. Nagkakapeklat pa 🥺
