How it works — get your consultation in 4 steps

Getting evaluated for medical-grade pigment treatment is entirely digital. There are no video calls, waiting rooms, or appointment schedules.

1. Complete the medical questionnaire: Answer focused questions about your skin history, prior treatments, allergies, and general health.
2. Upload clear photographs: Provide well-lit images of the affected areas so the EU-licensed doctor can accurately assess the type and distribution of your pigmentation.
3. Doctor evaluation: A registered doctor reviews your file and clinical images. If treatment is appropriate, they issue a REMPE electronic prescription in under 24 hours.
4. Present your prescription: Download the official REMPE PDF with its verifiable QR code. Present it on your smartphone or as a printed copy at any community pharmacy in Bilbao or throughout Spain.

Who qualifies

Hydroquinone is a prescription-only depigmenting agent indicated for specific epidermal pigment disorders. You may qualify for treatment if you meet the following clinical criteria:

• You have confirmed epidermal melasma, solar lentigines, or post-inflammatory hyperpigmentation.
• You are at least 18 years of age and not currently pregnant or breastfeeding.
• You have no history of hypersensitivity to hydroquinone, sulfites, or topical retinoids.
• You understand that medical management requires daily broad-spectrum photoprotection.

Hi-Doctor provides topical dermatology consultations only. Patients presenting with severe nodular or cystic disease, suspicious pigmented lesions, or conditions requiring oral isotretinoin or systemic antibiotics are referred to in-person specialist care.

What Hydroquinone actually does

Hydroquinone is a competitive inhibitor of tyrosinase, the rate-limiting enzyme responsible for converting L-tyrosine into melanin inside melanocytes. By blocking this pathway, it decreases the synthesis and increases the degradation of melanosomes.

Formulation	Key Actives	Clinical Focus
Hydroquinone 4% Cream	Hydroquinone 4%	Standard monotherapy for localized epidermal melasma.
Hydroquinone 4% Gel	Hydroquinone 4%	Alternative lightweight vehicle suitable for oilier skin types.
Compounded Melasma Formula	Hydroquinone 4% + Tretinoin 0.025% + Kojic Acid 2% + Niacinamide 4%	Synergistic multi-action approach combining tyrosinase inhibition, cellular turnover, and anti-inflammatory action.

Depigmentation is not immediate. Visible lightening typically begins after 4 to 8 weeks of consistent nightly application. Full treatment cycles usually run for 12 to 16 weeks, after which the doctor may recommend a rest period or a maintenance regimen to avoid tachyphylaxis or irritation. Daily use of broad-spectrum SPF 50+ (ideally tinted with iron oxides to block visible light) is mandatory, as UV and visible light trigger instant melanogenesis that reverses clinical progress.

Side effects and when to stop

Most side effects are mild, localized, and occur during the first few weeks of therapy. Common reactions include mild erythema, localized peeling, transient stinging, and temporary dryness.

You should discontinue application and contact a doctor if you experience severe contact dermatitis, intense burning, or swelling. Extended, unsupervised use over many continuous months carries a rare risk of exogenous ochronosis (a blue-black pigmentary change), which is why courses must remain finite and medically supervised.

Why Hi-Doctor vs. walking into a clinic

Booking a private dermatology consultation in Bilbao often takes weeks and can cost upwards of 100 € to 150 € before pharmacy costs. Hi-Doctor streamlines the process to a transparent 40 € one-off consultation.

• No risk: If the doctor assesses your case and determines hydroquinone is not safe or indicated for you, your 40 € fee is refunded in full.
• Spain's official standard: Approved prescriptions use the official REMPE private electronic system. Under Directive 2011/24/EU, cross-border prescriptions containing mandatory fields under Commission Implementing Directive 2012/52/EU can also be presented to pharmacists in other EU countries, who review the prescription and may dispense a locally authorized product.
• Speed: Doctors review questionnaires and, when clinically appropriate, issue prescriptions in under 24 hours.
