TCA (15-25%) is a keratolytic, causing protein coagulation. Non-toxic substance.
When applied to the skin, TCA causes the formation of a frost effect. Depending on the depth of necrosis, the following types of frost effect are distinguished:
- Pink frost: “pointed” - throughout the entire depth of the stratum corneum; “clouds” - granular layer
- White (milky): translucent film - the border of the granular and spinous layer
- White deaf, compact: up to the basement membrane, dermal papillae
- Solid white with a yellowish/greenish tint: up to the reticular layer (there will be a scar in this place).
