Sutricon, opinions and questions

What's better for an 18 month baby, Contractubex gel or Sutricon gel? A scar after removing stitches near the mouth.

Good morning. A week ago I scalded myself with boiling water, after about 3 days small blisters with liquid formed, which spontaneously burst. The skin is red and dry. Itches a little. In the place where there were no blisters, the skin is brown. Will it peel off and regenerate or will there be a scar?

What can be improved scar? Unfortunately, I used Sutricon ointment too early and the scar became convex. How can this be reversed?

Is it possible to apply arnica ointment on scars immediately after removing stitches?

Good morning, Please and hint, the child has had smallpox, his scabs are now falling off and in some places he has red marks after the scabs. They are not convex or concave, just a red mark. Are these scars and is it smeared with something? How so, what. We have sutrucion gel at home or will I be suitable?
