Tretinoin in Spain (Retirides, Treclinac): Uses

Tretinoin is the prescription retinoid cream or gel used for acne and, off-label, for sun-damaged skin. In the UK and the US it is known as Retin-A. In Spain it is sold as Retirides (tretinoin alone) and, combined with the antibiotic clindamycin, as Treclinac. Every tretinoin product in Spain needs a prescription: a pharmacy cannot sell it over the counter, whatever you were told abroad.

Dr. Pedro Yelamo Vera is a GP licensed in Spain (Colegiado No. 484814280).

For a medical emergency, call 112 or go to the nearest local emergency department. Do not wait for a video consultation or an online reply.

What is tretinoin used for?

• Acne with blackheads, whiteheads and small inflamed spots. It is a first-line treatment in European and US acne guidelines, alone or with benzoyl peroxide or an antibiotic.
• Keeping acne away after a course of oral treatment, because it stops pores blocking again.
• Photo-ageing (fine lines, rough texture, sun spots). This use is well studied but is off-label in Spain, so the doctor decides case by case.
• Some pigmentation problems, under a dermatologist, often in a combined cream.

Tretinoin is the only retinoid of this group with a strong evidence base for wrinkles. It works slowly: acne usually improves after eight to twelve weeks, and the skin benefits in photo-ageing take months of steady use.

Retirides, Treclinac, Retin-A: which name is which?

Name	What it is	Where you see it
Retin-A	Tretinoin cream or gel	US, historically the UK
Retirides	Tretinoin cream	Spain (prescription)
Treclinac	Clindamycin + tretinoin gel	Spain (prescription); Treclin in the UK, Ziana or Veltin in the US
Retinol, retinal, retinyl	Cosmetic vitamin A forms, much weaker	Shops and pharmacies, no prescription
Isotretinoin	Oral capsule for severe acne	Spain (prescription, dermatology)

Treclinac adds clindamycin, an antibiotic, for acne with inflamed spots. Because of antibiotic resistance it is used for limited periods and never as the only treatment for years.

Is tretinoin prescription-only in Spain?

Yes. Retirides and Treclinac are medicamentos sujetos a prescripción médica. A Spanish pharmacy dispenses them against a Spanish prescription, including a private electronic one. Websites that ship "tretinoin cream" without a prescription are selling outside the law, and the product is not checked. You can confirm the status of each presentation on the AEMPS CIMA database.

A GP can assess acne by video and, where clinically appropriate, prescribe a topical retinoid. Severe, scarring or cystic acne is referred to dermatology. Our acne page explains how that works.

How is tretinoin used safely?

• Apply a small amount at night to clean, dry skin, as the leaflet or your doctor says. More does not work faster; it only irritates.
• Expect dryness, redness and peeling in the first weeks. Your doctor may tell you to start gradually and build up as the skin gets used to it. Acne can look worse before it gets better.
• Use a plain moisturiser. Avoid scrubs, strong acids and alcohol-based toners at the same time.
• Sunscreen every morning, SPF 30 or higher, and a hat in strong sun. Tretinoin makes skin burn far more easily. This matters in Spain all year, not only in summer.
• Keep it away from the eyes, nostrils, lips and any broken skin. Do not use it after waxing.
• If you stop, the benefit fades over months: it is a long-term treatment.

Who should not use tretinoin?

• Pregnancy, trying to conceive, or breastfeeding. Oral retinoids cause severe birth defects. Only tiny amounts of tretinoin pass through the skin, but the leaflet and most doctors advise against it; there are safer acne options in pregnancy.
• Eczema or very sensitive, damaged or sunburnt skin, until it has healed.
• Known allergy to tretinoin or to the ingredients of the cream.
• People who cannot avoid strong sun or sunbeds.

Tretinoin or isotretinoin: what is the difference?

They sound alike and both are retinoids, but they are different medicines. Tretinoin goes on the skin and treats mild to moderate acne and sun damage. Isotretinoin is a capsule taken by mouth for severe or scarring acne, prescribed by a dermatologist with blood tests and strict pregnancy prevention. One does not replace the other. We explain the capsule in our isotretinoin guide.

Side effects and when to see a doctor

Dry, red, peeling or stinging skin is expected at first and usually settles. See a doctor if:

• the skin is raw, swollen, blistered or very painful;
• you get a rash beyond the treated area, or swelling of the face or lips (stop and seek care);
• acne has not improved after three months of correct use;
• you become pregnant while using it (stop and tell your doctor; there is no need for alarm, but a review is sensible).

Talking it through with a doctor by video

Dr. Yelamo is a GP licensed in Spain. He sees adults, children and pregnant patients by video, every day from 07:30 to 20:30 (Spain time). In the visit he will:

• Look at your skin on camera and ask how long the acne has been there and what you have tried.
• Ask about pregnancy plans, sun exposure and other skin products.
• Explain whether tretinoin, a combination gel or another treatment fits, and how to start it gently.
• Refer severe or scarring acne to a dermatologist.

He does not promise any test or prescription before the visit. Where clinically appropriate, following a genuine evaluation. Treatment and prescriptions are issued solely at the doctor's discretion based on evidence-based clinical guidelines.

A prescription is never guaranteed: it is issued only where clinically appropriate after a genuine evaluation, as a private electronic prescription under Spanish law. This service is for urgent, non-emergency care. In an emergency, call 112.

See how the Urgent Care video visit works. It lasts 15 minutes and costs €50.
