Prescription retinoid guide · 2025

Understand tretinoin for acne and anti-ageing – before you start a prescription.

Tretinoin is a prescription-only retinoid. It can transform acne and sun-damage – but only when used correctly, under medical supervision. This page explains the basics, compares common ways to get treatment, and shows you gentler over-the-counter alternatives.

See the difference between tretinoin, over-the-counter retinol and adapalene.
Compare in-person dermatologists, GPs and online dermatology services.
Learn why a slow, barrier-friendly start matters more than the highest strength.

Nothing here is personal medical advice. The goal is to help you ask better questions when you speak with your own doctor or dermatologist – and to avoid random, unregulated tretinoin from the internet.

Ways to access tretinoin – side by side

This table compares routes to treatment, not specific brands. Regulations and availability vary by country. Always follow the rules where you live and work with a licensed prescriber.

	Route	Best for	What you get	Pros	Watch-outs
View option	In-person dermatologist visit Gold standard	Severe, scarring, unclear cases	Face-to-face exam + prescription if appropriate	Highest accuracy, broadest treatment options, proper follow-up. Ideal for painful, scarring acne or when you’re not sure it’s “just acne”.	Cost, wait times and travel. Can feel like a big step for milder breakouts.
View option	Online dermatology services Most convenient	Mild–moderate acne or photo-ageing	Photo review + Rx if suitable	No waiting room, fast digital follow-up, refills handled online. Often bundled with a simple routine (cleanser, moisturiser, sunscreen).	Not ideal for very severe, rapidly worsening or medically complex skin problems.
View option	GP / family doctor Good first step	General acne with other health questions	Whole-person review + possible referral	Knows your medical history, can adjust other medications and order blood tests or referrals when needed.	Some GPs prescribe tretinoin directly, others prefer a dermatologist to supervise treatment.
Compare retinol at Retynol.com	Over-the-counter retinoids Gentler alternative · Retynol.com	Mild acne, early fine lines, “test the waters”	Cosmetic retinol · retinal · OTC adapalene	Easier to access and often easier to tolerate. Good step if you want vitamin A benefits but are not ready for a full prescription journey yet.	Not equivalent to tretinoin for more severe acne. Don’t delay seeing a doctor if you have scarring, pain or deep nodules.

Not sure you’re ready for prescription tretinoin?

Many people want to start gentler, with over-the-counter retinol or retinal, before moving up to prescription tretinoin. That’s where Retynol.com comes in.

Who is retinol a better fit for?

You have mild acne, early fine lines or uneven texture – not severe disease.
You want to see how your skin handles vitamin A before a prescription.
You prefer a slower, barrier-friendly approach with less initial irritation.

If your skin is scarring, painful or affecting your mental health, skip straight to a doctor. Prescription care matters more than finding the “perfect” cosmetic cream.

How tretinoin actually works

Tretinoin is an active form of vitamin A that binds directly to receptors in skin cells. Over time it can:

Unclog pores and reduce formation of blackheads and whiteheads.
Improve fine lines and rough texture by speeding up cell turnover.
Even out tone when combined with consistent daily sunscreen.

Results are measured in months, not days. The early phase often brings more dryness and visible breakouts while deeper clogs surface – this is why support products (moisturiser, SPF) matter so much.

Safety basics your doctor considers

Pregnancy, breastfeeding or planning pregnancy.
History of eczema, rosacea or very sensitive skin.
Other prescription medications for skin, mood or immune conditions.
How much time you spend in strong sunlight and how you use sunscreen.

Always share a full list of creams, gels, peels and supplements you already use – including “natural” products – so your prescriber can avoid risky combinations.

Tretinoin FAQ

How long until I see results?

For acne, many dermatologists quote around 8–12 weeks for clearer patterns to show up, and several months for photo-ageing changes. This can feel slow, especially if the first weeks look worse.

Is tretinoin stronger than retinol?

Yes. Tretinoin is far more potent than cosmetic retinol, which is why it’s prescription-only in many countries and used at much lower percentages (for example 0.025–0.1%). Retinol and retinal can still be very useful – see Retynol.com for a structured look at those options.

Can I buy tretinoin online without a prescription?

In many places, buying prescription tretinoin without a proper medical consultation is illegal and risky. Products from unregulated sites may be fake, contaminated or too strong. Your skin and long-term health are worth a legitimate prescription.

What if tretinoin feels too strong for me?

Talk to your prescriber first – sometimes a lower strength or reduced frequency is enough. If you decide that prescription tretinoin is not for you right now, over-the-counter retinol can be a reasonable alternative. Again, Retynol.com can help you choose a sensible gentler product.
