Everyday use and best practices

Tretinoin cream is a topical retinoid used mainly to treat acne. Use it exactly as directed by your prescriber.

Morning vs evening dosing

Tretinoin cream is usually applied in the evening, because it makes the skin more sensitive to sunlight.

To use it correctly, start by thoroughly cleansing your face. Once your skin is clean and dry, a thin layer of the cream should be applied directly to the affected areas.

Taking with or without meals

This is a cream for use on the skin, so it is not affected by meals and there are no dietary restrictions.

Safety priorities

Who should avoid it (MHRA warnings)

Tretinoin should not be used by people with known hypersensitivity to tretinoin or any of its ingredients.

Women who are pregnant or planning to conceive should also avoid it because of the potential risks associated with retinoid use. It should also be avoided on broken or sunburnt skin and in people with a personal or family history of skin cancer.

Activities to limit (driving, work safety)

Patients may experience side effects such as increased skin sensitivity and irritation while using tretinoin. Avoid direct sunlight and sunbeds where possible.

Use a sunscreen during the day to protect against heightened sun sensitivity.

Dosage and adjustments

General regimen (NHS guidance)

It is usual to start with a lower concentration, such as 0.025%, to assess skin tolerance before moving to a stronger one if needed.

Apply a thin layer once daily in the evening, to clean, dry skin, allowing the skin to adapt over time.

Special cases (elderly, comorbidities)

For elderly patients or those with existing health conditions, beginning with the lowest strength is advisable. They require careful monitoring to ensure that the treatment does not exacerbate pre-existing skin conditions, such as eczema or particularly sensitive skin.

These precautions reduce the likelihood of irritation.

What’s inside and how it works

Ingredients overview

Tretinoin, a form of vitamin A, is the active ingredient in tretinoin cream. It speeds up skin cell turnover. The cream also contains excipients that vary by product.

Mechanism basics explained simply

Tretinoin works by unclogging pores and promoting skin cell turnover, which helps to treat and prevent acne lesions. It can also reduce fine lines and improve pigmentation, although these are not licensed uses.

Main indications

Approved uses (MHRA listing)

Topical tretinoin is licensed in the UK for treating acne vulgaris.

Off-label uses in UK clinics

Outside of its primary indications, some dermatologists in the UK prescribe tretinoin cream off-label, for example for photoaging, uneven skin tone and hyperpigmentation.

Interaction warnings

Food interactions

There are no known food or drink interactions with topical tretinoin.

Drug conflicts

Tretinoin can interact unfavourably with other topical products that dry or irritate the skin, such as benzoyl peroxide, salicylic acid, abrasive cleansers and products containing alcohol. Tell your healthcare provider about any unusual side effects, which can also be reported through the Yellow Card scheme.

Alternative choices

For those who experience adverse reactions to tretinoin cream, alternatives are available through the NHS, for example:

• Adapalene: a topical retinoid that is generally considered gentler on the skin.
• Benzoyl peroxide or azelaic acid: non-retinoid topical options for acne.

Regulation snapshot

Tretinoin cream is regulated by the MHRA and is a prescription-only medicine (POM) in the UK, because of its potency and potential side effects.

Frequently asked questions

• Is tretinoin safe for long-term use? Extended use under healthcare supervision is generally safe, but it's wise to have regular check-ups.

• Is tretinoin cream available without a prescription? No – in the UK tretinoin cream is a prescription-only medicine.
