Hydrocolloid dressings are used to treat uninfected wounds. [6] Dressings may be used, under medical supervision, even where aerobic infection is present; the infection should be treated appropriately. [citation needed] The dressing is applied to a cleaned wound. Hydrocolloid patches are sometimes used on the face for acne.
Timing is important to wound healing. Critically, the timing of wound re-epithelialization can decide the outcome of the healing. [11] If the epithelization of tissue over a denuded area is slow, a scar will form over many weeks, or months; [12] [13] If the epithelization of a wounded area is fast, the healing will result in regeneration.
The 3D polymeric network of hydrogels is highly hydrated with 90-99% water w/w; it is capable of binding many times more water molecules when assembled than in the uncross-linked state. [2] [3] Hydrogel dressings can absorb up to 600 times their initial amount of water, including fluid-based wound exudates.

For instance, in wound healing, P21 has been found to allow mammals to heal spontaneously. It even allows some mammals (like mice) to heal wounds without scars. [5] [6] The LIN28 gene also plays a role in wound healing. It is dormant in most mammals. [7] Also, the proteins MG53 and TGF beta 1 play important roles in wound healing. [8]
Merbromin's best-known use is as a topical antiseptic to treat minor wounds, burns, and scratches. [3] It is also used in the antisepsis of the umbilical cord, [4] and the antisepsis of wounds with inhibited scar formation, such as neuropathic ulcers and diabetic foot sores. [5]

Cauterization (or cauterisation, or cautery) is a medical practice or technique of burning a part of a body to remove or close off a part of it. It destroys some tissue in an attempt to mitigate bleeding and damage, remove an undesired growth, or minimize other potential medical harm, such as infections when antibiotics are unavailable.
