Will scalds from boiling water leave scars?

In general, whether scalds from boiling water leave scars depends on specific factors such as the severity of the burn, treatment methods, and individual physical characteristics. If a scald occurs, it is recommended to treat it promptly and correctly, and seek medical attention when necessary. The details are as follows:

If the burn is mild, involving only redness and slight swelling of the skin surface, with no blisters or only small blisters, and if the area is immediately rinsed under running cool water for more than 20 minutes, followed by keeping the wound clean and dry without infection, scarring is usually unlikely. Healthy adults generally have strong skin regeneration ability, and with proper care, the wound typically heals smoothly without leaving noticeable marks.

However, if the burn reaches the dermis layer, resulting in large blisters or broken skin, or if initial treatment is delayed or improper—leading to wound infection or pus formation—scarring is more likely. Infants, elderly individuals, or those with a predisposition to scarring (scar-prone constitutions) have weaker skin healing capacity or are prone to excessive fibrous tissue growth; even moderately severe burns may result in obvious scars or hyperpigmentation.

After a burn, avoid scratching the wound to prevent damage to newly forming skin. Before the wound heals, avoid contact with dirty water, and apply burn ointment as directed by a physician. In terms of diet, reduce intake of spicy and stimulating foods, and consume more protein- and vitamin-rich foods to support skin recovery. If pigmentation occurs after healing, avoid direct sun exposure and use sun protection measures outdoors to help the skin gradually return to its normal color.
