When the skin heals from chicken pox, it usually creates too much or too little collagen in one spot. This often results to uneven skin tone. Further, the scars left behind are products of excess irritation and damage caused by physical trauma.
Again, picking or popping the blisters can result to permanent scarring. Chicken pox scars usually look like pitted scars that are caused by inflammatory acne. The scars may either be superficial or deep and measures more than 3mm in diameter.
