Wow! Remarkable healing signs!
If you are concerned about acne-like lesions, you may use 2% Hydrogen peroxide, it's harmless and breaks down to water and oxygen. Dilute the stores 3% Hydrogen peroxide with clean, preferably distilled water in ratio: 2 parts HP to 1 part water. It will limit propagation of bacteria around and in the pimples/rash.
Apply with cotton ball and wash your fingers after, because it could sting. It leaves sometimes whitish marks on skin, that disappear after minutes, or nearly right away if you wash under running water.
