What is Hydroquinone?
❗ Prescription drug — Rx from a dermatologist required. Do not self-administer
Strongly inhibits melanin synthesis, but long-term use carries the risk of ochronosis (paradoxical darkening). Must be used under medical supervision.
Caution
Do not use continuously for more than 12 weeks. Use only under a dermatologist's supervision.
Main causes & characteristics of Hydroquinone
Hydroquinone is known to work by inhibiting the activity of tyrosinase, an enzyme involved in melanin synthesis. However, prolonged or high-concentration use has been associated with reported risks of side effects such as ochronosis (paradoxical pigmentation), and for this reason it is classified and regulated as a prescription medication.
Managing Hydroquinone
Hydroquinone is a prescription-only ingredient and must be used exclusively under the care and prescription of a dermatologist; self-purchase and self-administration are not recommended. The duration of use, concentration, and any accompanying ingredients should be determined by a qualified physician. If irritation or discoloration occurs, use should be discontinued immediately and consulting a dermatologist is strongly recommended.
