Who qualifies
Hi-Doctor provides online consultations for adult patients dealing with melasma. Qualification depends entirely on clinical assessment by an EU-licensed doctor.

- Eligible conditions: Epidermal, dermal, or mixed melasma patterns that have not responded adequately to standard over-the-counter skincare.
- Required evaluation: You must upload well-lit photographs of the treatment area so the doctor can verify the pigmentation pattern.
- In-person referrals: Severe cystic dermatoses, undiagnosed pigmented lesions, suspicious moles, or conditions requiring systemic oral medications are not treated online and are referred to in-person clinical care.
- Contraindications: Hydroquinone is not prescribed during pregnancy or breastfeeding, or for individuals with known hypersensitivities to phenolic depigmenting agents.
What Hydroquinone actually does
Hydroquinone is a potent topical depigmenting agent that acts as a competitive inhibitor of tyrosinase. Tyrosinase is the rate-limiting enzyme responsible for converting L-tyrosine into melanin inside melanocytes.
By blocking tyrosinase activity, Hydroquinone halts the enzymatic oxidation process and inhibits melanogenesis. Over a typical treatment cycle, existing pigmented keratinocytes shed naturally through cellular turnover, while new, lighter skin cells replace them.
Formulations and clinical approach
Depending on your questionnaire and photo assessment, an EU doctor may prescribe:
- Hydroquinone 4% cream (HQUIN) or gel (Licoforte): Applied thinly at night to affected areas for defined cycles (typically 8 to 12 weeks) rather than indefinite use.
- Compounded melasma formula: A modified Kligman-style topical containing hydroquinone 4% + tretinoin 0.025% + kojic acid 2% + niacinamide 4% to accelerate turnover and enhance penetration.
The mandatory role of photoprotection
Daily broad-spectrum SPF 50+ is not optional; it is the core foundation of treatment. Melasma is directly triggered by UV radiation and high-energy visible (HEV) light. Without daily broad-spectrum sun protection, depigmenting agents will fail. Tinted mineral sunscreens containing iron oxides provide essential protection against visible light that standard chemical filters cannot block. Patients should also note that melasma is chronic and prone to relapse upon sun exposure.
Side effects and when to stop
Most patients tolerate topical hydroquinone well during short, supervised cycles, but transient local reactions can occur during the initial weeks of use.
- Mild, common reactions: Mild erythema, localized dryness, temporary stinging, and superficial peeling. These often stabilize with moisturizer application.
- When to stop: Discontinue use and contact a medical professional immediately if you experience intense burning, swelling, contact dermatitis, or blistering.
- Exogenous ochronosis risk: Unsupervised, continuous use over many months or years can cause exogenous ochronosis—a blue-black tissue discoloration. To prevent this, doctors prescribe hydroquinone in strict, defined cycles with scheduled rest periods.
