Who qualifies

Hydroquinone is a potent, medical-grade depigmenting agent prescribed exclusively for melasma within Hi-Doctor's dermatology pathway. Eligibility is assessed individually by the prescribing physician based on your clinical profile.

• Eligible candidates: Adults presenting with facial melasma (epidermal, dermal, or mixed pattern) that has not responded adequately to over-the-counter skincare.
• Contraindications: Pregnant or breastfeeding individuals, active acute inflammation, broken skin, eczema flares, or known hypersensitivity to hydroquinone or sulphites.
• Topical scope: Hi-Doctor provides topical dermatology treatments only. Severe, nodular, or scarring conditions, as well as cases requiring oral therapies, are referred to in-person care.

What Hydroquinone actually does

Hydroquinone works by inhibiting tyrosinase, the rate-limiting enzyme responsible for melanin synthesis in melanocytes. By blocking tyrosinase, it halts new pigment production while existing melanin sheds naturally with epidermal turnover.

Depending on clinical assessment, our doctors may prescribe branded Hydroquinone 4% cream (such as HQUIN), Hydroquinone 4% gel (such as Licoforte), or a compounded melasma formula containing hydroquinone 4%, tretinoin 0.025%, kojic acid 2%, and niacinamide 4%. Noticeable lightening typically begins between weeks 4 and 8, with peak efficacy observed around week 12 of a structured cycle.

Daily application of broad-spectrum SPF 50+ is mandatory throughout treatment. Melasma is heavily activated by ultraviolet and visible light; without strict daily photoprotection (ideally tinted formulations with iron oxides), depigmentation therapies fail, and melasma relapses.

Side effects and when to stop

While effective, hydroquinone requires strict medical supervision to prevent adverse reactions and long-term complications.

• Mild, expected effects: Transient erythema (redness), localized dryness, mild burning, and superficial peeling during the first 2 to 3 weeks.
• When to pause and report: Severe swelling, intense burning, blistering, or spreading dermatitis. Contact the medical team via your patient account if these occur.
• Exogenous ochronosis risk: Prolonged, continuous use without breaks can cause paradoxically dark blue-black pigmentation. For this reason, treatment is restricted to defined courses rather than indefinite use.
