Is Blistex MedPlus the Right Lip Balm with SPF for You?

 

Dry, cracked, or sore lips are surprisingly common — and often underestimated. Whether it's cold winter winds, central heating, or prolonged sun exposure, your lips can take a real battering throughout the year. The NHS notes that the skin on your lips is thinner and more delicate than the rest of your face, making it especially vulnerable to environmental damage. That's where a lip balm with SPF like Blistex MedPlus Lip Repair comes in. It combines soothing, moisturising ingredients with SPF15 sun protection, giving your lips both immediate comfort and longer-term defence.

Available from our skin care range at Cured Pharmacy for just £2.49, Blistex MedPlus is a trusted over-the-counter option that's been used for years to manage chapped and sun-damaged lips. It's compact, easy to carry, and requires no prescription.

 

How Does Blistex MedPlus Lip Repair Actually Work?

 

Blistex MedPlus works through a multi-ingredient approach, targeting dryness, irritation, and UV exposure simultaneously. Here's how its key components contribute:

  • Dimethicone — a silicone-based emollient that forms a breathable barrier on the lip surface, locking in moisture and preventing further water loss.
  • Allantoin — a well-established skin-conditioning agent that promotes cell renewal and soothes irritated tissue.
  • Camphor and Menthol — provide a mild cooling sensation that temporarily relieves discomfort and tightness associated with chapped lips.
  • SPF15 UV filters — help protect against both UVA and UVB radiation, which can worsen dryness and contribute to long-term lip damage.

Together, these ingredients address the root causes of lip discomfort rather than simply masking symptoms. The emollient base softens and smooths, while the active components work to calm and protect.

 

Who Is Blistex MedPlus Lip Repair Suitable For?

 

This product is designed for adults and older children who experience dry, chapped, or sun-exposed lips. It's particularly useful if you spend time outdoors, live in a dry or cold climate, or find your lips frequently cracking during seasonal changes. People who wear lip cosmetics regularly may also benefit, as makeup can sometimes strip natural moisture from the lip surface.

  • Adults with chronically dry or chapped lips
  • People who spend extended time outdoors in sun or wind
  • Those recovering from mild lip irritation or peeling
  • Anyone wanting daily UV protection for their lips alongside moisturisation

Soothing Action Yes — cooling and calming Moisturising only
Price (approx.) £2.49 £1.50–£3.00

 

Is Blistex MedPlus Safe to Store and Use Long-Term?

 

Blistex MedPlus should be stored below 25°C, away from direct sunlight and heat sources. Keeping it in a bag or pocket is fine for everyday use, but avoid leaving it in a hot car or on a sunny windowsill, as heat can alter the texture and reduce the effectiveness of the UV filters. Check the expiry date printed on the packaging before use — using an expired lip balm with SPF may mean the sun protection is no longer reliable.

If you have a known allergy to any of the listed ingredients — particularly fragrances, menthol, or camphor — review the full ingredient list carefully before applying. As a lip balm with SPF, this product is intended for external use on the lips only. Avoid contact with the eyes. If you are pregnant, breastfeeding, or have a skin condition affecting your lips, speak to your pharmacist before use. You can also browse our wider range of creams and ointments for other topical skin care options.

This product is a medicine. Speak to your doctor or pharmacist before using if you have an underlying medical condition or are taking other medicines.

Specifications of Blistex MedPlus Lip Repair Lip Balm with SPF15

 

What Is Blistex MedPlus Lip Repair and What Is It Used For?

 

Blistex MedPlus Lip Repair is a topically applied lip balm formulated to treat and prevent dryness, chapping, and discomfort of the lips. It contains a blend of emollient and skin-conditioning ingredients alongside SPF15 sun protection filters. It is used to relieve the symptoms of dry, cracked, or irritated lips caused by cold weather, wind, low humidity, sun exposure, or habitual lip licking. The NHS advises that protecting lips from UV radiation is important, as the skin on the lips has very little natural melanin and is therefore more susceptible to sun damage than other areas of the face.

This product is available over the counter without a prescription and is suitable for everyday use as part of a lip care routine. It is not intended to treat cold sores, infections, or any underlying dermatological condition without appropriate medical guidance.

 

What Do You Need to Know Before Using Blistex MedPlus?

 

Before applying Blistex MedPlus, check the full ingredient list for any known allergens. The following contraindications and warnings apply:

  • Do not use if you are allergic to any of the listed ingredients, including menthol, camphor, or fragrance components.
  • Avoid applying to broken, infected, or severely inflamed lip skin without first seeking medical advice.
  • Do not use on children under 12 without pharmacist guidance.
  • Avoid contact with the eyes — if contact occurs, rinse thoroughly with water.
  • If you are pregnant or breastfeeding, consult your GP or pharmacist before use.
  • Do not use as a substitute for prescribed treatments if your lips are affected by a diagnosed skin condition.

Regarding drug interactions, no clinically significant interactions have been identified for topically applied lip balm products of this type. However:

  • If you are using any prescribed topical treatments on or near your lips, apply Blistex MedPlus separately and allow adequate time between applications.
  • Avoid combining with other camphor- or menthol-containing products on the same area simultaneously.

 

How Should You Apply Blistex MedPlus Correctly?

 

Using Blistex MedPlus correctly ensures you get the most from both its moisturising and sun-protective properties. Follow these steps:

  1. Ensure your lips are clean and dry before application.
  2. Remove the cap and apply the balm directly to your lips using the tip of the stick.
  3. Cover the entire lip surface, including the corners of the mouth.
  4. Reapply as needed throughout the day — particularly before going outdoors, after eating, or after drinking.
  5. For sun protection, reapply at least every two hours during prolonged sun exposure, as recommended by the NHS for all SPF products.
Indication Age Group Dose Frequency
Dry / chapped lips Adults & children 12+ Apply a thin, even layer As needed throughout the day
Sun protection (lips) Adults & children 12+ Apply generously before exposure Every 2 hours during sun exposure
Preventative daily use Adults Apply a thin layer Morning and evening

 

What Are the Possible Side Effects of Blistex MedPlus?

 

Side effects from Blistex MedPlus are uncommon when used as directed. However, as with any topical product containing active ingredients, some individuals may experience a reaction. If you are exploring other topical options for skin concerns, our skin care collection includes a range of alternatives.

Common side effects:

  • Mild tingling or cooling sensation upon application (due to menthol and camphor — usually transient)
  • Temporary redness at the application site
  • Slight dryness if overused in some individuals

Less common side effects:

  • Allergic contact dermatitis — presenting as itching, swelling, or a rash around the lips
  • Increased sensitivity or burning sensation in those with pre-existing lip conditions
  • Rarely, photosensitivity reactions in individuals sensitive to UV filter ingredients

If you experience any signs of a serious allergic reaction — including swelling of the lips, face, or throat, difficulty breathing, or severe skin reactions — stop use immediately and seek urgent medical attention.

 

How Should You Store Blistex MedPlus Lip Repair?

 

Correct storage helps maintain the product's effectiveness, particularly the integrity of the SPF filters. Follow these guidelines:

  • Store below 25°C in a cool, dry place.
  • Keep away from direct sunlight and heat sources such as radiators or car dashboards.
  • Replace the cap firmly after each use to prevent contamination and drying out.
  • Do not share the product with others to avoid cross-contamination.
  • Keep out of reach and sight of young children.
  • Do not use after the expiry date printed on the packaging — expired SPF products may not provide adequate UV protection.

For general guidance on sun protection and skin care, the NHS provides helpful advice on protecting your skin from UV damage year-round. If you have concerns about a skin condition affecting your lips or face, consider speaking to your GP or browsing our creams and ointments section for additional topical options.

Frequently Asked Questions

Where can I buy Blistex MedPlus lip balm with SPF15 online in the UK?

You can buy Blistex MedPlus lip balm with SPF15 directly from Cured Pharmacy online for just £2.49, with no prescription required. It is dispatched quickly and discreetly to your door. Simply add it to your basket and select your preferred delivery option at checkout.

How does Blistex MedPlus lip balm work in the body?

Blistex MedPlus works topically — it does not enter the bloodstream in any meaningful way. Dimethicone creates a protective barrier on the lip surface to lock in moisture, while allantoin soothes and supports skin cell renewal. The SPF15 UV filters absorb and reflect ultraviolet radiation before it can damage the delicate lip tissue.

How do I use Blistex MedPlus lip balm step by step?

Start with clean, dry lips and apply the balm directly from the stick, covering the entire lip surface including the corners. Reapply as often as needed throughout the day, especially before going outdoors or after eating and drinking. For sun protection, reapply every two hours during prolonged outdoor exposure.

How often should I apply Blistex MedPlus during the day?

There is no strict limit on how many times you can apply Blistex MedPlus — use it whenever your lips feel dry or uncomfortable. For sun protection specifically, the NHS recommends reapplying SPF products at least every two hours when outdoors. Most people find applying it three to five times daily is sufficient for everyday lip care.

Can children use Blistex MedPlus lip balm?

Blistex MedPlus is generally considered suitable for adults and children aged 12 and over. For younger children, it is advisable to speak to a pharmacist before use, as ingredients such as menthol and camphor may not be appropriate for very young children. Always keep the product out of reach of infants and toddlers.

What are the side effects of Blistex MedPlus lip balm?

Most people tolerate Blistex MedPlus well, though a mild tingling or cooling sensation is common on first application due to the menthol and camphor content. Less commonly, some individuals may experience redness, itching, or signs of allergic contact dermatitis around the lips. If you develop swelling, a rash, or difficulty breathing, stop use immediately and seek medical advice.

Is Blistex MedPlus suitable for use during pregnancy?

Blistex MedPlus is applied topically to the lips and systemic absorption is considered minimal, but if you are pregnant or breastfeeding it is always sensible to check with your GP or pharmacist before starting any new product. This is particularly relevant if you have sensitive skin or known ingredient allergies. Your pharmacist can advise on the most appropriate lip care option for you during pregnancy.

What are the alternatives to Blistex MedPlus lip balm?

Alternatives include other medicated lip balms such as Carmex Classic, as well as plain emollient options like Vaseline Lip Therapy. The key advantage of Blistex MedPlus over many alternatives is its combination of medicated soothing ingredients and SPF15 protection in a single product. You can explore further options in our skin care collection at Cured Pharmacy.

Does Blistex MedPlus protect against both UVA and UVB rays?

Yes, Blistex MedPlus contains SPF15 UV filters that provide protection against both UVA and UVB radiation. UVB rays are primarily responsible for sunburn, while UVA rays penetrate more deeply and contribute to longer-term skin ageing and damage. Using a lip balm with SPF daily — even in winter — is a sensible habit, as UV radiation is present year-round in the UK.

Can I wear Blistex MedPlus under lipstick or lip gloss?

Yes, Blistex MedPlus can be used as a base layer under lipstick or lip gloss. Apply it first, allow a moment for it to settle, and then apply your lip cosmetic on top. Bear in mind that applying other products over the top may reduce the effective SPF protection, so reapplication may be needed if sun protection is a priority.

How long does one Blistex MedPlus lip balm stick last?

The duration depends on how frequently you apply it, but most users find a single stick lasts several weeks with regular daily use. Storing it correctly — away from heat and with the cap replaced after each use — helps prevent the product from drying out prematurely. Check the expiry date on the packaging and replace the product if it has passed.

What happens if I accidentally swallow some Blistex MedPlus?

Small incidental amounts ingested during normal lip use are unlikely to cause harm in adults. However, if a child swallows a significant quantity, contact NHS 111 or your nearest A&E for advice. Keep the product packaging to hand so medical staff can identify the ingredients quickly.

Can I use Blistex MedPlus on a cold sore?

Blistex MedPlus is not formulated to treat cold sores, which are caused by the herpes simplex virus and require antiviral treatment such as aciclovir cream. Applying a shared lip balm stick to an active cold sore could also risk spreading the virus. If you have a cold sore, speak to your pharmacist about appropriate antiviral treatments available over the counter.

Is there any research supporting the ingredients in Blistex MedPlus?

Yes — allantoin is a well-documented skin-conditioning agent with published evidence supporting its role in promoting epidermal cell renewal and soothing irritated skin. Dimethicone is widely recognised as an effective emollient and barrier-forming ingredient in dermatology. SPF15 UV filters are regulated and tested under EU and UK cosmetic regulations to ensure they provide the stated level of sun protection.

How should I store Blistex MedPlus lip balm to keep it effective?

Store Blistex MedPlus below 25°C in a cool, dry place away from direct sunlight and heat sources. Avoid leaving it in a hot car or on a sunny windowsill, as heat can degrade the UV filters and alter the texture of the balm. Always replace the cap firmly after use and check the expiry date before applying. You can find more topical skin care products in our creams and ointments section.

How Should You Use Blistex MedPlus Lip Repair?

Blistex MedPlus is straightforward to use, but applying it correctly makes a real difference to how well it works. Always start with clean, dry lips to ensure the ingredients can absorb and form an effective barrier without interference from food, drink, or other products.

Avoid licking your lips after application, as this removes the product and can worsen dryness over time. If you are using any other topical treatments near your lips, allow adequate time between applications.

What Is the Correct Dose of Blistex MedPlus?

There is no fixed "dose" for a topical lip balm in the same way as an oral medicine, but applying a thin, even layer is sufficient for most purposes. Applying more than needed does not increase effectiveness and may feel uncomfortable.

When Is the Best Time to Use Blistex MedPlus?

For everyday lip care, applying Blistex MedPlus in the morning and before bed is a good habit. Morning application ensures your lips are protected and moisturised before you head outdoors, while an evening application allows the emollient ingredients to work overnight when your lips naturally lose moisture.

For sun protection specifically, apply generously at least 15 minutes before going outside and reapply every two hours during prolonged exposure — or more frequently if you have been eating, drinking, or swimming. Don't forget that UV radiation is present even on overcast days in the UK.

How Long Can You Use Blistex MedPlus For?

Blistex MedPlus can be used as part of your daily lip care routine on an ongoing basis. There is no recommended maximum duration for use in healthy adults. However, if your lips do not improve after a couple of weeks of regular use, or if they worsen, it is worth speaking to your pharmacist or GP to rule out an underlying skin condition.

Do not use the product beyond its printed expiry date, as the SPF filters may no longer provide reliable protection after this point. If you notice any change in texture, smell, or colour, discontinue use and replace the product.

Do not exceed the recommended dose. If in doubt, speak to your pharmacist.

Great product

It’s a great medicated balm for chapped lips. My go to in the winter time.

What Are the Most Common Side Effects of Blistex MedPlus?

Blistex MedPlus is well tolerated by most people when used as directed. The most frequently reported experience is a mild tingling or cooling sensation immediately after application, which is caused by the menthol and camphor content. This is expected and usually fades within a minute or two.

  • Mild tingling or cooling sensation on application
  • Temporary redness at the application site
  • Slight tightness if applied in very large amounts

What Are the Less Common Side Effects of Blistex MedPlus?

A small number of people may experience reactions that go beyond the expected cooling sensation. These are less common but worth being aware of, particularly if you have a history of sensitive skin or ingredient allergies.

  • Itching or burning sensation around the lips
  • Localised redness or swelling that persists after application
  • Dry or flaking skin around the lip border
  • Allergic contact dermatitis — a delayed reaction causing a rash, blistering, or crusting

If you notice any of these symptoms, stop using the product and allow the area to settle. You may wish to speak to your pharmacist about patch testing or identifying the specific ingredient causing the reaction.

What Are the Serious Side Effects of Blistex MedPlus?

Serious side effects from a topically applied lip balm are rare but not impossible. The most significant concern is a systemic allergic reaction, also known as anaphylaxis, which can occur in individuals with severe sensitivities to specific ingredients such as fragrance components or UV filters.

  • Swelling of the lips, face, tongue, or throat
  • Difficulty breathing or swallowing
  • Widespread skin rash or hives beyond the application area
  • Dizziness or feeling faint

These symptoms require immediate medical attention. Call 999 or go to your nearest A&E if you experience any of the above after using this product.

What Should You Do If You Experience Side Effects of Blistex MedPlus?

For mild side effects such as tingling or temporary redness, simply stop applying the product and allow the area to recover. Rinsing the lips gently with cool water can help ease discomfort. If symptoms persist for more than 24 hours or worsen, contact your pharmacist or GP.

For suspected allergic reactions, discontinue use immediately and seek medical advice. Keep the product packaging so that healthcare professionals can review the full ingredient list. You can report suspected adverse reactions to the MHRA via the Yellow Card scheme at yellowcard.mhra.gov.uk.

Can Blistex MedPlus Interact With Other Medicines or Products?

No clinically significant drug interactions have been identified for Blistex MedPlus when used as directed on the lips. However, if you are using prescribed topical treatments on or near your lips — such as aciclovir cream for cold sores or a corticosteroid for a lip dermatitis — apply them separately and allow time between applications to avoid diluting either product's effectiveness. Avoid combining with other camphor- or menthol-containing topical products on the same area at the same time, as this may increase the risk of local irritation.

If you are concerned about any side effects, contact your pharmacist or GP immediately.
