Common Pitfalls
Translation Traps (for Russian speakers)
- Avoid literal translation as 'депигментация' is a direct medical loanword and is correct. Confusion may arise with 'обесцвечивание', which is broader and can refer to objects, not just biological pigment loss.
- Do not confuse with 'депиляция' (hair removal).
Common Mistakes
- Misspelling as 'depigmentization' or 'depigmenation'.
- Using it as a verb (the verb is 'depigment').
- Confusing with 'hypopigmentation' (reduced, not complete loss of pigment).

FAQ
Frequently Asked Questions
No. Albinism is a genetic condition present from birth causing a lack of melanin production. Depigmentation is the process or result of losing existing pigment and can be acquired later in life (e.g., from vitiligo, injury, or chemicals).
It depends on the cause. Depigmentation from some inflammatory conditions may be temporary, while loss from vitiligo or certain chemical burns is often permanent. Repigmentation treatments exist but are not always successful.
The process itself is not directly harmful, but the loss of skin pigment increases the risk of sunburn and skin cancer due to loss of melanin's protective function. The underlying cause may require medical attention.
Depigmentation refers to a complete loss of pigment, resulting in white skin or hair. Hypopigmentation is a partial loss, resulting in a lighter but not completely white area.
