Abstract: The present invention relates to an optional attachment type functional heating patch for skin condition improvement with a stretch marks and soreness prevention function, which actively improves use efficiency and wear convenience by adopting a structure that can be directly attached to or detached from clothes including underwear or skin, more fundamentally solves soreness or other foreign body sensations or rejections due to its self-preheating or exothermic structural properties, and further maximizes skin condition improvement efficiency by combining nutrients that can be delivered to the dermis of the skin. The optional attachment type functional heating patch comprises: a pad layer (10) of a set size that is placed in close contact with the local area by retaining a set elastic force to correspond to the curvature of an object; a care layer (20) for inducing the prevention and improvement of skin diseases due to skin absorption or skin irritation of a skin-improving agent applied on one or both sides of the pad layer or filled therein; and an adhesive layer (30) formed on one side or both sides of the pad layer to induce attachment to the object. Accordingly, the optional attachment type functional heating patch is configured to be directly attached to or detached from the clothing including underwear or the skin.
