Repeated application of rigid collodium to the same spot can cause damage to the skin and actual scarring. Safely remove the dried collodium film by using Collodium Remover and cotton balls. Soak the cotton balls in the remover and wipe at the collodium effect until it peels off gently.
IMPORTANT NOTE: Be careful when using collodium remover to avoid the eyes and mouth. Apply in a well ventilated area. Keep away from open flames, as this product is highly flammable.
