A non-sterile, biodegradable, synthetic (e.g., cyanoacrylate) substance intended to be applied over a superficial wound to set and form a barrier to reduce skin exposure to external contaminants. Sometimes referred to as a liquid bandage, it is normally available [non-prescription] over-the-counter (OTC) and may be intended as an alternative to a conventional skin-cover adhesive strip. After application, this device cannot be reused.
