Braun BT3240 - Beard Trimmer Series 3 & Hair Clippers with Gillette Fusion5 ProGlide Razor

Is a Beard Trimmer and Razor Set Worth It?

If you've ever tried to maintain a neat beard using two separate tools bought at different times, you'll know how frustrating it can be. The beard trimmer and razor set format solves that problem neatly. The Braun BT3240 — part of the trusted Series 3 range — combines a precision beard trimmer, hair clippers, and a Gillette Fusion5 ProGlide razor in one kit, all for £32.99. That's a genuinely practical bundle for men who want a consistent, well-groomed look without spending a fortune or cluttering the bathroom shelf. For anyone exploring men's grooming alongside their wider health routine, you'll find a range of relevant products in our men's health collection too.

Braun has been manufacturing grooming tools for decades, and the BT3240 reflects that experience. The trimmer features 20 adjustable length settings — ranging from 1 mm to 20 mm — so whether you prefer heavy stubble or a close-cropped beard, you can dial in exactly what you need. The Gillette Fusion5 ProGlide razor, included in the kit, is one of the most widely used razors in the UK, known for its five-blade design that reduces drag and helps deliver a smooth finish along the jawline and neck.

How Does the Braun BT3240 Trimmer Work?

The BT3240 operates on a rechargeable lithium-ion battery, delivering up to 45 minutes of cordless runtime from a full charge. The trimmer head uses precision-ground steel blades that self-sharpen over time, maintaining cutting efficiency without the need for blade replacement in normal use. Here's how the key mechanisms work:

• The adjustable comb attachment locks into 20 length positions, giving you 1 mm increments for accurate beard shaping.
• The hair clipper attachment allows you to manage sideburns and longer hair sections without switching devices.
• The Gillette Fusion5 ProGlide razor uses five anti-friction blades with a precision trimmer on the reverse for detailing around the moustache and sideburns.
• The ergonomic grip design reduces hand fatigue during longer grooming sessions.

It's worth noting that the trimmer body is not fully waterproof, so it should be kept away from running water. The razor, however, can be used wet with shaving foam or gel — a combination that works well for men who prefer a wet shave finish on the neck and cheeks.

Who Should Use the Braun BT3240 Grooming Kit?

This kit is designed for adult men who want a versatile, all-in-one grooming solution. It's particularly well suited to:

• Men who maintain a short-to-medium beard and need consistent length control.
• Those who prefer a hybrid grooming routine — trimming with clippers and finishing with a razor.
• Men new to beard grooming who want a straightforward, easy-to-use starter kit.
• Anyone looking for good value without compromising on blade quality.

It's not specifically designed for very coarse or thick hair that may require a more heavy-duty trimmer motor, though most men will find the BT3240 more than adequate for everyday use. If you have a skin condition such as folliculitis or razor bumps, it's worth speaking to a pharmacist or GP before starting a new shaving routine, as blade choice and technique can significantly affect skin health.

Is the Braun BT3240 Suitable for Sensitive Skin?

Men with sensitive skin can generally use the Braun BT3240 trimmer without issue, as the blades glide rather than pull. However, when using the Gillette Fusion5 ProGlide razor — particularly on the neck — it's sensible to apply a shaving gel or foam first to create a protective barrier. Razor bumps and ingrown hairs are more common in men with curly or coarse hair, and using a single-direction shaving technique can help reduce this risk. If you experience persistent skin irritation, our skin care collection includes products that may help soothe post-shave redness and dryness.

This product is a grooming device, not a medicine. However, if you have an underlying skin condition or are taking medicines that affect skin healing, speak to your doctor or pharmacist before changing your shaving routine.

What Is the Braun BT3240 and What Is It Used For?

The Braun BT3240 is a men's grooming kit that combines a Series 3 beard trimmer, hair clippers, and a Gillette Fusion5 ProGlide razor. It is used for trimming and shaping facial hair, maintaining stubble at a consistent length, clipping sideburns and short hair, and achieving a close shave along the jawline and neck. It is a non-medicinal consumer device intended for external use on the face and head only.

Good grooming isn't just about appearance — maintaining clean, well-kept facial hair can also support skin hygiene. Dead skin cells and sebum can accumulate beneath beard hair, and regular trimming helps reduce this build-up. The NHS notes that good personal hygiene, including regular skin cleansing, plays a role in overall skin health. This kit makes it easier to keep your routine consistent without needing multiple separate tools.

What Do You Need to Know Before Using the Braun BT3240?

Before using this grooming kit, please read the following precautions carefully:

• Do not use the trimmer on broken, inflamed, or infected skin.
• Do not use the razor on active acne lesions, open cuts, or areas with eczema or psoriasis flares.
• The trimmer body is not waterproof — keep it away from running water and do not use it in the shower.
• Keep the device out of reach of children.
• Do not attempt to disassemble or repair the device yourself.
• If you have a bleeding disorder or are taking anticoagulant medicines (such as warfarin), take extra care when using the razor to avoid nicks.
• Men with folliculitis, pseudofolliculitis barbae (razor bumps), or rosacea should consult a GP or pharmacist before starting a new shaving routine.

There are no known drug interactions with this device, as it is not a medicinal product. However, if you use topical skin treatments — such as retinoids or steroid creams — on your face, be aware that these can thin the skin and increase sensitivity to blade shaving.

• No known drug interactions (non-medicinal device).
• Topical retinoids may increase skin sensitivity — allow skin to settle before shaving.
• Topical corticosteroids can thin skin over time — use the razor with extra care if applying these to the face.

How Should You Use the Braun BT3240 Correctly?

Using the BT3240 correctly will give you the best results and help protect your skin. Follow these steps for a safe and effective grooming session:

1. Charge the trimmer fully before first use (approximately 8 hours).
2. Select your desired length setting by rotating the adjustment dial on the trimmer body.
3. Begin trimming dry beard hair, moving the trimmer against the direction of hair growth for an even cut.
4. Switch to the hair clipper attachment if you need to manage sideburns or longer sections.
5. Once trimming is complete, apply shaving foam or gel to the areas you wish to shave clean.
6. Use the Gillette Fusion5 ProGlide razor in short, gentle strokes along the jawline and neck.
7. Rinse the razor head under warm water after every few strokes to clear hair and foam.
8. After use, clean the trimmer head with the included brush and wipe the body with a dry cloth.

What Are the Possible Side Effects of Using the Braun BT3240?

As a grooming device rather than a medicine, the BT3240 does not cause systemic side effects. However, improper use — particularly of the razor — can cause localised skin reactions. The NHS provides guidance on managing skin irritation caused by shaving, noting that technique and blade quality both play a significant role.

Common side effects (razor use):

• Mild skin redness or irritation after shaving
• Razor burn, particularly on the neck
• Minor nicks or cuts if the razor is used without lubrication
• Temporary dryness or tightness of the skin post-shave

Less common side effects:

• Ingrown hairs (pseudofolliculitis barbae), more common in men with curly hair
• Folliculitis (inflammation of hair follicles) if the blade is not kept clean
• Contact dermatitis if you are sensitive to nickel (present in some blade alloys)

If you experience persistent redness, swelling, or signs of infection after shaving, stop use and consult your GP or pharmacist. Our hair care collection includes products that may support scalp and facial hair health alongside your grooming routine.

How Should You Store the Braun BT3240?

Proper storage will extend the life of both the trimmer and the razor. Follow these guidelines:

• Store the trimmer in a cool, dry place away from direct sunlight and moisture.
• Do not store in a bathroom cabinet directly above a sink where steam and water splashes are common.
• Keep the Gillette Fusion5 ProGlide razor in its protective cap when not in use to preserve blade sharpness.
• Store the charging cable separately to avoid tangling or damage.
• Keep out of reach of children at all times.
• Do not store in temperatures below 0°C or above 40°C, as this can damage the lithium-ion battery.
