Silverx (silver sulfadiazine) is a standard, appropriate cream for a burn like this, and from your photo, these look like small, superficial blisters that are already settling without any sign of infection.
Next Steps
Keep using it as you have been, leave the blisters intact rather than popping them, and cover the area loosely so it doesn't catch on clothing. Wash your hands before each application.
Health Tips
See a doctor if the area turns more red, swollen or warm, starts oozing, or you develop fever, since that would mean a secondary infection needing different treatment.
