My toddler got scratched on the face 3 weeks ago by a cat, there deep cuts how long do the scars take to heal? they are still pink and i'm worrying

Scarring: Sunlight can cause darkening of the scar tissue. If you are going outside be sure to apply high quality sunscreen to the skin for protection. Applying vit e gel will also aid in healing. Due to the depth of the scratches there may be some permanent scarring.

See Dr.: Should see physician.Sometimes significant infections can occur from cat scratches and need antibiotic treatment.Cat-scratch can present as tender, swollen lymph nodes near the site of bite or scratch or on the neck,and usually limited to one side.Condition referred to as regional lymphadenopathy and occurs1–3 week after inoculation.Common usually benign infectious disease by Bartonella bacteria

6 months to a year: This kind of scratch will take six months to a year to heal. This pink tissue is the new healing skin, it is very sensitive. Be sure to protect it with suncreen. In about six months you will have an idea of the final scar. Eventually the pinkness will fade and around a year you can see what it will look like finally. It will grow with the baby as she grows.
