How it works — get your consultation in 4 steps

Acquiring a prescription treatment for melasma is direct, fully RGPD-compliant, and handled without video calls or waiting rooms.

1. Complete the questionnaire: Answer focused clinical questions regarding your skin type, past hyperpigmentation treatments, and current medical status.
2. Upload clear photographs: Take direct photos of the affected areas in good lighting so the doctor can assess pigment distribution and rule out contraindications.
3. Doctor evaluation: An EU-licensed doctor reviews your case and determines whether a depigmenting regimen is clinically safe for you.
4. Download your REMPE prescription: If approved, your doctor issues a valid REMPE electronic prescription file (PDF) to your secure account and by email within 24 hours.

Who qualifies

Hydroquinone is a regulated, prescription-only medical treatment in Spain and the European Union. Online consultation is suitable for adults managing persistent facial hyperpigmentation who meet clinical safety criteria.

• Eligible candidates: Adults diagnosed with epidermal or mixed melasma, post-inflammatory hyperpigmentation (PIH), or stubborn solar lentigines.
• Mandatory photo review: You must submit clear photos of your skin; Hi-Doctor's doctors evaluate pigment depth and skin barrier condition prior to prescribing.
• Exclusions: Women who are pregnant or breastfeeding cannot use hydroquinone. Anyone with active skin infections, open wounds, or undiagnosed suspicious pigmented lesions will be directed to an in-person clinic.
• Topical scope only: Hi-Doctor only prescribes topical treatments. Oral isotretinoin and severe, nodular, or cystic conditions are strictly referred to in-person care.

What Hydroquinone actually does

Hydroquinone acts as a potent tyrosinase inhibitor. Tyrosinase is the rate-limiting enzyme responsible for converting L-DOPA into melanin inside melanocytes.

By blocking this enzymatic pathway, hydroquinone reduces the production of new pigment while existing epidermal pigment naturally exfoliates away. Because melasma is a chronic, relapsing condition driven by UV exposure and visible light, treatment is prescribed in structured, time-limited courses rather than used indefinitely.

Daily broad-spectrum photoprotection is mandatory. Without strict daily SPF 50+ application—ideally tinted with iron oxides to block visible high-energy light—melanocytes will restimulate and depigmenting therapy will fail.

Side effects and when to stop

Most patients experience mild, manageable skin changes during the initial weeks of therapy as cellular turnover accelerates.

• Expected initial effects: Mild transient erythema, slight peeling, and localised dryness. These can be managed by applying a non-comedogenic moisturiser 20 minutes after application.
• Adverse reactions: Severe burning, intense swelling, blistering, or spreading contact dermatitis.
• Exogenous ochronosis: An extremely rare blue-black pigmentation condition associated with long-term, unmonitored use spanning many consecutive months without cyclical breaks.

If you experience severe irritation, stop application immediately and contact your doctor through your secure Hi-Doctor account inbox.
