Key points
- "Medical grade" is a marketing phrase, not a legal category. UK medicines are prescription-only (POM), pharmacy (P) or general sales list (GSL) (MHRA, classification).
- A product sold as "medical grade" may be a cosmetic, and cosmetics are not licensed medicines (MHRA, Guidance Note 8).
- Several acne treatments can be bought over the counter (BAD, acne leaflet). If acne is not improving, the NHS advises seeing a GP (NHS, Acne).
Skin products are sold with labels such as "medical grade" and "prescription strength". This article explains what those labels mean, how medicines are actually classified in the UK, and when a prescription becomes part of the picture.
Some products can be picked off a shelf, some can only be bought from a pharmacy with a pharmacist present, and some can only be supplied once a prescriber has assessed the person and issued a prescription.
What does "medical grade" skincare mean?
Not every skin product is a medicine. In UK law, a cosmetic is intended mainly for "cleaning them, perfuming them, changing their appearance, protecting them, keeping them in good condition", in relation to the outer parts of the body (MHRA, Guidance Note 8).
MHRA guidance states that "Cosmetic products are not licensed medicinal products and are not intended for the treatment or prevention of any specific adverse condition in humans". The same guidance treats products to treat or prevent spots and acne as medicines.
Phrases such as "medical grade" or "clinical strength" are not among the MHRA's legal categories for medicines (MHRA, classification), so a product carrying one of those phrases may still be a cosmetic.
How are medicines classified in the UK?
The Medicines and Healthcare products Regulatory Agency (MHRA) places medicines into three categories (MHRA, classification):
- Prescription-only medicine (POM): supplied only with a valid prescription issued by an authorised health professional.
- Pharmacy medicine (P): sold without a prescription, but only from a pharmacy and in the presence of a pharmacist.
- General sales list medicine (GSL): available in shops and supermarkets as well as pharmacies.
The MHRA explains that, in part, classification "rests on how much health professional input is needed to diagnose and treat the conditions for which the medicine might be used". It describes the guiding principle as optimising "timely access to effective treatments while reducing the risk of harm from improper use".
Which skin treatments can be bought without a prescription?
Some acne treatments can be bought directly from a pharmacy, while others require a prescription. According to the British Association of Dermatologists, over-the-counter options for mild acne include products containing ingredients such as benzoyl peroxide, azelaic acid and nicotinamide, and pharmacists can advise on whether these may be suitable (BAD, acne leaflet). More persistent, widespread or severe acne may require prescription treatments from a GP or dermatologist.
The NHS also recommends self-care measures such as using non-comedogenic skincare and make-up products and avoiding picking or squeezing spots, which can increase the risk of scarring (NHS, Acne).
“I encourage patients to tell me what treatments they have already tried and how long they have been using them. Acne treatments often take time to work, so understanding what has and hasn't helped allows me to recommend appropriate next steps, whether that's an over-the-counter product or referral to a GP for further assessment.”

When does a prescriber become involved in skin treatment?
Some skin conditions are managed with treatments that are only available on prescription. For rosacea, the NHS notes that the condition cannot be cured, but that treatment from a GP can help control the symptoms (NHS, Rosacea).
A GP may suggest prescription creams and gels applied to the skin, or a course of antibiotics, and may refer to a dermatologist if treatments are not working.
For acne, the NHS advises seeing a GP where self-treatment is not helping, or where spots are deep, painful or causing scars. It notes that a GP may offer treatments only available on prescription, or refer to a dermatologist (NHS, Acne).
How do prescription and over-the-counter skin treatments compare?
The answer depends on the condition and the person. For acne, the NHS describes prescription treatments as stronger than products sold in pharmacies and shops (NHS, Acne). However, the most appropriate option depends on individual circumstances and should be discussed with a clinician.
A prescription-only treatment is not automatically the best option for a given person. Suitability depends on the condition, its severity, medical history and what has already been tried.
How does the prescription route work in the UK?
In the UK, a prescription-only medicine can only be sold or supplied in accordance with a prescription from an appropriate practitioner (HMR 2012, reg 214). That group includes doctors and dentists, and nurses and pharmacists who have trained as prescribers, with some other professions able to prescribe within set limits.
The prescription is then taken to a pharmacy, where the medicine is prepared under the supervision of a pharmacist. Sometimes it is filled at a dispensing doctor's surgery instead (MHRA, classification).
Sometimes there is no suitable licensed medicine available for a patient's specific needs (MHRA, specials guidance). Depending on the circumstances, a prescriber may choose an imported medicine, a manufactured special, or a medicine prepared specifically for that individual by a pharmacy. When a medicine is prepared for a named patient against a prescription, this is often referred to as compounding (Medicines Act 1968, s10). Pharmacies that specialise in this type of personalised medicine are commonly known as compounding pharmacies.
How unlicensed medicines are regulated is explained in our article on personalised skincare.
What happens when standard skin treatment is not working?
When over-the-counter treatments have not helped, the British Association of Dermatologists advises seeing a healthcare professional (BAD, acne leaflet).
“A review will usually look at whether the diagnosis is correct, whether treatments have been used consistently and for long enough to assess their effect, how severe the acne is, and whether a different treatment approach may be more appropriate. Factors such as scarring, side effects and the impact of acne on a person's wellbeing may also be considered.”

Frequently asked questions
Is medical-grade skincare the same as prescription skincare?
No. A product sold as "medical grade" may be a cosmetic (MHRA, Guidance Note 8). Prescription skincare contains a prescription-only medicine.
What does "prescription strength" skincare mean?
"Prescription strength" is a marketing phrase, not a legal term in the UK. The legal category is "prescription-only medicine", one of the three categories the MHRA uses alongside pharmacy and general sales list medicines (MHRA, classification).
Can a dermatologist prescribe skincare?
Yes. A dermatologist is a doctor who specialises in skin conditions, described by the NHS as a skin specialist (NHS, Rosacea). Doctors are among the appropriate practitioners who can prescribe prescription-only medicines in the UK (HMR 2012, reg 214).
