Who qualifies

To safely get Tretinoin online, patients must meet defined medical criteria. Tretinoin 0.05% cream is a prescription-only retinoid formulated for topical application to treat photoageing and skin texture irregularities.

Please note that Hi-Doctor provides consultations and prescriptions for topical dermatology only. Systemic oral retinoids and severe skin diseases require an in-person dermatology visit.

What Tretinoin actually does

Tretinoin (all-trans retinoic acid) is the gold standard topical retinoid with decades of clinical evidence in treating photoageing. Unlike over-the-counter cosmetic retinols that must be converted by the skin, Tretinoin directly binds to nuclear retinoic acid receptors (RARs).

Tretinoin accelerates epidermal keratinocyte turnover and directly stimulates type I procollagen synthesis in the dermal extracellular matrix.

Because cellular remodelling happens gradually, clinical results develop across a predictable timeline:

  • Weeks 2–6 (Retinisation): The skin adapts. Mild flaking, dryness, and temporary redness are common as turnover accelerates.
  • Week 12: Improvement in surface texture, reduced roughness, and more uniform skin tone become visible.
  • Months 6–12: Dermal collagen synthesis yields visible softening of fine lines and improved skin elasticity.

Because Tretinoin increases sensitivity to ultraviolet radiation, applying broad-spectrum daily SPF 50 sunscreen is mandatory throughout treatment.

Side effects and when to stop

Most patients experience mild retinisation during the first month. Managing this involves applying a pea-sized amount at night to completely dry skin, starting 2 to 3 nights per week, and layering with a bland moisturiser.

Common and expected effects include mild peeling, tightness, and transient stinging. However, you should stop treatment and seek medical advice if you experience:

  • Severe burning, blistering, or extensive facial swelling.
  • Signs of allergic contact dermatitis or spreading rash.
  • Unexpected pregnancy (treatment must be ceased immediately).

Under EU Directive 2011/24/EU and Commission Implementing Directive 2012/52/EU, cross-border prescriptions containing mandatory prescriber and patient data can be presented at community pharmacies across EU member states. In Spain, pharmacists validate the electronic prescription QR code directly through the national private prescription verification platform. Outside Spain, pharmacists review the PDF details and may dispense an equivalent authorised medication, though dispensing discretion remains with the dispensing pharmacist.

Tretinoin works on a scale of months, not weeks.

Fill in the questionnaire and upload photos. An EU-licensed doctor decides whether tretinoin 0.05% is clinically appropriate and sets out a realistic build-up schedule and the daily SPF it requires. Valid electronic prescription in under 24 hours when approved; the €40 fee is refunded in full when it is not.
