An effective combination prescribed for mild to moderate acne. Lymecycline and adapalene gel work together to kill acne-causing bacteria while gently clearing blocked pores, blackheads and whiteheads.

  • Antibiotic tablets paired with a topical retinoid gel

  • Take a tablet each morning, apply gel in the evening

What are Lymecycline and Adapalene gel?

Lymecycline is an oral antibiotic that reduces acne-causing bacteria and inflammation.

Adapalene gel (also branded as Differin) is a topical retinoid (exfoliant) that’s also antibacterial. It helps remove dead skin, reduces inflammation, and helps control how much oil your skin’s making. 

Used together as a combination, lymecycline and adapalene gel (or lymecycline and Differin) can be effective in clearing existing spots and preventing new ones. Your GP or our clinicians can advise you on the right acne combination for your skin.

How do I take Lymecycline and apply Adapalene gel?

LymecyclineTake 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.

Adapalene gel

  1. Wash your face using a gentle, non-abrasive cleanser and pat dry.

  2. Wait 20-30 minutes until your skin is completely dry (applying to damp skin can increase irritation).

  3. Use a pea-sized amount of gel to cover your entire face (or affected areas).

  4. Gently spread the gel in a thin layer. Using more won’t make it more effective and could increase your risk of side effects.

  5. If skin feels tight or dry, wait a few minutes until the gel has absorbed, then apply a fragrance-free moisturiser labelled ‘non‑comedogenic’ (they’re not as likely to block pores).

  6. Leave the thin layer of gel on your skin overnight to work while you sleep.

How do Lymecycline and Adapalene gel work?

Lymecycline reduces the amount of acne-causing bacteria on your skin and calms inflammation. 

Adapalene gel is a retinoid that works to both clear current breakouts and help prevent new acne forming, by:

  1. Stimulating skin cell renewal within pores, helping to prevent clogging

  2. Reducing inflammation in existing breakouts

  3. Treating both inflammatory (red, painful pimples) and non-inflammatory acne (blackheads and whiteheads)

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.

Your doctor or clinician may recommend you keep using adapalene even after your skin clears to help prevent acne coming back. 

Are there any possible side effects from lymecycline or adapalene 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. 

Most adapalene gel side effects are mild and temporary. Typical effects include mild redness or discomfort, dryness, peeling and slight burning or stinging. Less common reactions are contact dermatitis or an acne flare-up. 

Seek immediate medical help if you get severe irritation or signs of allergy (difficulty breathing, severe rash, swelling). 

Adapalene can also increase your sensitivity to sunlight. 

Full details on use and safety are in the lymecycline and adapalene gel patient information leaflets.

Frequently asked questions

Lymecycline or adapalene 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

Adapalene gel

You can use other topical acne treatments alongside adapalene (such as benzoyl peroxide) but you should do it at a different time of day:

  • Apply other acne products in the morning

  • Use adapalene at night

  • Avoid using other retinoids (tretinoin, isotretinoin, tazarotene) at the same time as adapalene, as these may increase skin irritation

Always let your doctor or clinician know about all medications you're taking or using, especially those for other skin conditions like eczema.


If lymecycline and adapalene gel aren’t suitable for you, there are alternatives:

  • Other topical treatments such as benzoyl peroxide or azelaic acid.

  • 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.
