What are lymecycline and benzoyl peroxide gel?
Lymecycline is an oral antibiotic that reduces acne-causing bacteria and inflammation.
Benzoyl peroxide gel is an effective, prescription-only treatment for acne (also branded as acnecide). Wherever you get breakouts, spread a thin layer of gel to break down blackheads and whiteheads, reduce sebum (surface oil) and clear out dead cells. Benzoyl peroxide works to kill bacteria and reduce inflammation.
Used together as a combination, lymecycline and benzoyl peroxide (or lymecycline and Acnecide) can be effective in clearing existing spots and preventing new ones. Complete an acne assessment and your GP or our clinicians can advise you on the right acne combination for your skin.
How do I take Lymecycline and apply Benzoyl Peroxide gel?
Lymecycline
Take one daily lymecycline tablet, ideally in the morning. Sit or stand while swallowing it, with plenty of water. Avoid lying down for at least 30 minutes so it’s less likely to irritate your stomach.
Benzoyl peroxide gel
Wash your skin with a mild cleanser
Pat dry and wait 15 minutes
Put a pea‑sized amount of ge on your finger
Cover the whole affected area with a thin layer
Let it dry before you use moisturiser or put on make‑up
Wash your hands again
Use benzoyl peroxide gel in the morning and evening, remembering to add a (non-oily) sunscreen of at least SPF30 afterwards and try to avoid sunlight. If you have sensitive skin, start with one nightly gel application before trying to include the second in your routine.
If you notice redness, try using benzoyl peroxide every other night and build back up gradually to applying twice a day. To get the best results, don’t wash off benzoyl peroxide gel. Leave it overnight on your skin, to unclog pores and fight bacteria that cause breakouts.
How do lymecycline and benzoyl peroxide gel work?
Lymecycline reduces the amount of acne-causing bacteria on your skin and calms inflammation.
Benzoyl peroxide breaks down on contact with your skin, releasing oxygen and benzoic acid:
Oxygen attacks the blocked pores where bacteria like to grow. Fewer germs means calmer, less active spots and faster clear ups.
Benzoic acid acts as a mild exfoliant, loosening the mix of dead cells and oil that can form blackheads and whiteheads. It also dries excess oil, so pores are less likely to get clogged with a build up of oil and dead skin.
Combining the two increases the chance of getting smoother, less inflamed skin by tackling different acne triggers at the same time.
Is this combination acne treatment effective?
It usually takes about 6 weeks before oral antibiotics like lymecycline show noticeable improvement.
Benzoyl peroxide is an established, effective treatment for reducing inflammatory spots by around a third. Most users see calmer skin and fewer new spots after 4 weeks. You should keep going for 12 weeks before you judge the full results. Over time you can expect lower inflammation, smoother skin texture and fewer new breakouts.
Are there any possible side effects from lymecycline or benzoyl peroxide gel?
Lymecycline may make skin more sensitive to sunlight, so follow a good sun protection routine. Apply daily sun block (non oily, fragrance-free) and keep out of the sun when it’s most intense. You should also avoid sun beds.
Other possible side effects include nausea, upset stomach or diarrhoea. Always let your doctor or clinician know if you get severe or persistent symptoms.
Benzoyl peroxide
As benzoyl peroxide gel gets to work you may experience dryness, peeling or mild burning early on. You have the option to step down to one application a day if this happens, and try to moisturise after the gel dries.
Let the gel dry fully so you don’t bleach your hair or fabrics like clothes, towels and bedding. It’s not common to get severe redness or swelling. If you do, stop using benzoyl peroxide straight away and speak to your doctor or clinician.
Benzoyl peroxide can increase your sensitivity to sunlight, so it’s even more important to follow a good sun protection routine. Apply daily sun block (non oily, fragrance-free) and keep out of the sun when it’s most intense. You should also avoid sun beds.
Full details on use and safety are in the lymecycline and benzoyl peroxide patient information leaflets.
Acne treatments
Frequently asked questions
Lymecycline or benzoyl peroxide gel are not recommended treatments if you’re pregnant, breastfeeding or trying for a baby. Ask your doctor or our clinicians about safer alternatives.
Lymecycline
Lymecycline can interact with other medicines you’re taking at the same time, making it less effective or more potent. These include other antibiotics and:
Indigestion remedies (antacids)
Warfarin, a medicine that helps prevent blood clots
Medicines containing aluminium, bismuth, calcium, iron, kaolin, magnesium or zinc
Quinapril, a medication for high blood pressure or heart failure
Acne medicines like isotretinoin that contain vitamin A
Tablets like furosemide that make you urinate more (diuretics)
Epilepsy medications such as phenytoin or carbamazepine
Iron supplements
Supplements that contain aluminium, bismuth, calcium, magnesium or zinc
Benzoyl peroxide gel
You should not take Isotretinoin alongside benzoyl peroxide, and avoid layering strong retinoids, high‑strength salicylic acid or alcohol‑rich toners at the same time. The combination can irritate your skin. Oral medicines are often used alongside gels, which are designed to work only on the surface of your skin.
Always let your doctor or our clinicians know about all medications you're taking or using, especially those for other skin conditions like eczema.
If lymecycline and benzoyl peroxide gel aren’t suitable for you, there are alternatives:
Other topical treatments such as azelaic acid gel.
Other oral antibiotics combined with topical treatments.
If you’re a woman, hormonal acne treatments include co‑cyprindiol.
Lifestyle tweaks like a balanced diet, gentle skincare and avoiding heavy make‑up.
A dermatologist can recommend isotretinoin for severe, stubborn acne.
Light therapy and chemical peels may be more effective than medication in some cases.
Getting stubborn whiteheads, blackheads or cysts removed using special tools could improve how your skin looks short term, but can also scar it.
Your GP or our clinicians can advise you on the best acne treatment for clearer, healthier looking skin.
