Do you have advice on how to get rid of this spider bite scar? (Photos)

Hidef protocols can help with keloid and hypertrophic scars on the face and body. Surgery is often not needed if lasers are introduced. 
In our office, we combine treatments starting with topical pre-conditioning of the scars with Plato's Scar Serum for hypertrophy and Melarase PM for pigmentation. Fractional RF, laser, and micro fractional RF can help limit scar growth. Kenalog IIT can also help reduce scar thickness.

Spider bites can be brutal in terms of scarring. The entire scar can be excised and the resultant wound closed. This would replace the large circle with a straight line scar but you can never fully eradicate a scar.

At this point, the scar can be excised and you will be left with a straight line.   The straight line will look much better than the circle scar.  I am sorry you were bitten by the spider, but we can make the scar better.
