Kills Acne Bacteria

Erythromycin 4% antibiotic targets and eliminates Cutibacterium acnes, the primary bacteria responsible for inflammatory acne breakouts.

Accelerates Cell Turnover

Tretinoin 0.025% retinoid increases epidermal renewal, shedding dead skin cells faster to keep pores clear and prevent comedone formation.

Unclogs Pores

The keratolytic action of tretinoin loosens and clears existing blackheads and whiteheads, allowing trapped sebum to escape naturally.

Dissolves Excess Oil

The ethanol-based vehicle helps dissolve excess sebum on the skin surface, reducing oiliness and creating a less hospitable environment for bacteria.

02

Safety & compatibility

SAFE
Pregnancy & Breastfeeding

NOT safe during pregnancy or breastfeeding. Tretinoin is a retinoid with documented teratogenic effects in animal studies. Up to 24% of applied tretinoin may be absorbed systemically. Contraindicated for women who are pregnant, planning pregnancy, or nursing.

Fungal Acne (Malassezia) Safe

The formula contains no ferments, fatty acids, esters, or polysorbates. Only 5 ingredients total: erythromycin, tretinoin, ethanol, glycerol, and copolyvidone — all considered safe for fungal acne-prone skin.

Photosensitivity Warning

Tretinoin significantly increases sun sensitivity. Avoid prolonged sun exposure, tanning beds, and sunlamps during treatment. Always wear SPF 30+ sunscreen. Do not apply to sunburned skin.

Initial Purging Phase

Acne may appear to worsen during the first 2–4 weeks. This is a normal sign that the medication is working by pushing existing blockages to the surface. Do not discontinue treatment.

Low Comedogenic Risk

Rated 1/5 for comedogenicity. The alcohol-based solution formula is very unlikely to clog pores. Contains no oils, waxes, or heavy emollients.

Drug Interactions

Do not combine with other topical retinoids (adapalene, isotretinoin), benzoyl peroxide, or additional topical antibiotics (clindamycin) unless directed by a doctor. Avoid harsh exfoliants and peeling agents.

Ingredient breakdown

INGREDIENTS

Erythromycin 4% (40mg/g)Proven

A macrolide antibiotic that has been used in dermatology for decades. It works by inhibiting bacterial protein synthesis, effectively killing Cutibacterium acnes and reducing inflammatory lesion counts.

  • Mechanism: Binds to the 50S ribosomal subunit, blocking bacterial protein synthesis and halting bacterial growth
  • Clinical use: Well-established topical antibiotic for acne with decades of clinical evidence supporting efficacy
  • Absorption: Negligible percutaneous absorption when applied topically, making systemic side effects extremely rare
Long-term antibiotic use may contribute to bacterial resistance. Treatment is typically limited to 9–12 weeks to minimise this risk.

Tretinoin 0.025% (0.25mg/g)Proven

A first-generation retinoid (vitamin A derivative) and the gold standard in topical acne treatment. It increases epidermal cell turnover, prevents comedone formation, and improves overall skin texture and tone.

  • Mechanism: Acts as a keratolytic by markedly increasing cell turnover in the cornified epithelium including follicular ducts
  • Clinical use: FDA-approved for acne since 1971; extensive evidence base spanning over 50 years
  • Anti-aging bonus: Also promotes collagen production and can improve fine lines, hyperpigmentation, and skin texture over time
Contraindicated in pregnancy. Up to 24% total absorption possible. Causes significant photosensitivity — daily sunscreen is mandatory. Initial irritation (redness, peeling, dryness) is expected.

Ethanol 75.2% (vehicle)Vehicle

The primary solvent and vehicle base for the solution. Ethanol dissolves sebum on contact, delivers active ingredients into the skin, and evaporates quickly leaving a clean, matte finish.

  • Function: Solvent, penetration enhancer, and sebum-dissolving agent
  • Note: May cause stinging or burning on application, especially on broken or freshly shaved skin

Glycerol ExcipientMoisturiser

A humectant that attracts and retains moisture in the skin. Included to partially offset the drying effects of ethanol and tretinoin, helping maintain the skin barrier.

  • Function: Draws water to the skin surface, provides mild hydration and helps prevent excessive dryness

Copolyvidone ExcipientStabiliser

A film-forming polymer that helps the active ingredients adhere uniformly to the skin surface and stabilises the formulation for consistent drug delivery.

  • Function: Binder and film-forming agent ensuring even distribution and prolonged contact of actives with the skin

5 ingredients

Erythromycin (4% w/w), Tretinoin (0.025% w/w), Ethanol, Glycerol, Copolyvidone.

How to use

HOW TO USE
1

Cleanse Your Face

Wash the affected area with a gentle, non-irritating cleanser. Pat skin completely dry with a clean towel — do not rub. Wait 1–2 minutes to ensure skin is fully dry before application.

2

Prepare the Applicator

Press the screw cap onto the foam pad until you hear a "click." Gently invert the bottle several times so the solution soaks into the applicator pad evenly.

3

Apply to Affected Areas

Glide the foam applicator over affected skin areas using gentle, even strokes to apply a thin coat. Avoid the eye area, nostrils, lips, and any broken or sunburned skin. Avoid skin folds where product can accumulate.

4

Wash Hands & Wait

Wash your hands thoroughly after application. Allow 5–10 minutes for the solution to fully absorb and dry before applying moisturiser, serums, or makeup. The applicator closes automatically after use.

5

Continue for 9–12 Weeks

Apply once or twice daily as directed by your doctor. Be consistent — results may not be visible for several weeks. If irritation occurs, reduce frequency to once daily or every other day until skin adjusts.

06

Skin type compatibility

SKIN TYPES
Oily Skin
Excellent

Ideal match. The alcohol base dissolves excess sebum and the matte finish controls shine. Specifically indicated for acne associated with very oily skin.

Combination Skin
Good

Works well on oily T-zone. Apply mainly to acne-prone areas and avoid drier cheeks if they become irritated. Follow with a lightweight moisturiser on dry zones.

Normal Skin
Good

Effective for treating active breakouts. The drying effect of ethanol is manageable with a good moisturiser. Start with once-daily application.

Dry Skin
Moderate

The alcohol base and tretinoin can intensify dryness and peeling. Use sparingly, start every other day, and always follow with a rich moisturiser. Monitor for excessive irritation.

Sensitive Skin
Moderate

High ethanol content (75%) may cause stinging, redness, and irritation. Start with every-other-day use and build tolerance gradually. Patch test first.

Acne-Prone Skin
Excellent

Purpose-built for acne. Dual-action formula tackles bacteria and clogged pores simultaneously. Very low comedogenic risk (1/5). Fungal acne safe.

Budget-friendly alternatives (dupes)

DUPES
82% Match
Zineryt Solution (Erythromycin 4% + Zinc Acetate)
~£10–15
Budget Pick

Same erythromycin antibiotic base but replaces tretinoin with zinc acetate for skin protection. Less irritating and pregnancy-safe, but lacks the retinoid's pore-unclogging and anti-aging benefits. Best for those who cannot tolerate tretinoin.

65% Match
Adapalene Gel 0.1%
~£12–18
Budget Pick

A third-generation retinoid (adapalene) without antibiotic. Less irritating than tretinoin and more photostable, but does not directly target acne bacteria. Available over-the-counter in some countries. Good for purely comedonal acne.

60% Match
Benzoyl Peroxide Gel IP 2.5%
~£8–10
Budget Pick

An over-the-counter antibacterial gel that kills acne bacteria through oxidation without causing antibiotic resistance. No retinoid component, so lacks pore-clearing and anti-aging benefits. More suitable for mild inflammatory acne.

Frequently asked questions

FAQ

No. Aknemycin Plus contains tretinoin, a retinoid that is contraindicated during pregnancy and breastfeeding. High oral doses of tretinoin are teratogenic in animals, and up to 24% of topically applied tretinoin may be absorbed systemically. Women who are pregnant, planning to become pregnant, or breastfeeding must not use this product. Speak to your doctor about pregnancy-safe alternatives such as Zineryt (erythromycin + zinc) or azelaic acid (Skinoren).

Yes. Aknemycin Plus has an exceptionally clean, minimal formula with only 5 ingredients: erythromycin, tretinoin, ethanol, glycerol, and copolyvidone. It contains no fermented ingredients, fatty acids, fatty alcohols, esters, or polysorbates that could feed Malassezia yeast. This makes it one of the more fungal acne-friendly prescription acne treatments available.

It is generally not recommended to combine Aknemycin Plus with other active ingredients without your doctor's guidance. Since it already contains tretinoin (a retinoid), adding additional retinol, retinoids, AHA (glycolic/lactic acid), BHA (salicylic acid), or vitamin C can significantly increase irritation, peeling, and sensitivity. If you wish to use these ingredients, ask your prescriber about alternating schedules or using them on different nights. Do not use benzoyl peroxide products simultaneously as they can deactivate the formula.

Aknemycin Plus is specifically indicated for acne associated with very oily skin. The alcohol-based solution dissolves excess sebum and leaves a matte finish, making it ideal for oily and combination skin types. It can work for normal skin with good moisturiser support. Those with dry or sensitive skin may find the ethanol base too drying and should consider gel-based alternatives like Treclin or Epiduo, which tend to be better tolerated.

Most users begin to see meaningful improvement after 4–6 weeks of consistent use. However, it is normal for acne to initially worsen during the first 2–4 weeks (the "purging" phase) as tretinoin increases cell turnover and brings underlying blockages to the surface. Do not be discouraged by this — it is a sign the treatment is working. Full results are typically achieved by weeks 9–12. Consistency is crucial: do not stop treatment prematurely during the purge phase.

Apply Aknemycin Plus as the first step after cleansing and drying your skin. The correct order is: (1) gentle cleanser, (2) pat dry completely, (3) apply Aknemycin Plus to affected areas, (4) wait 5–10 minutes for absorption, (5) apply moisturiser, (6) sunscreen in the morning. Do not apply other topical products before Aknemycin Plus, as they can create a barrier that reduces absorption of the active ingredients.

No. Aknemycin Plus has a comedogenic rating of 1/5 (very low). The alcohol-based solution contains no oils, waxes, silicones, or heavy emollients. In fact, it actively works to unclog pores through the keratolytic action of tretinoin and by dissolving sebum with its ethanol base. It is one of the least likely acne treatments to cause additional pore congestion.

Aknemycin Plus should be used within the prescribed treatment course of 9–12 weeks. Always check the expiry date printed on the outer carton. Store below 30°C and keep in the original carton to protect from light. Do not use past the expiry date. Dispose of unused product at your local pharmacy — do not pour down the drain or throw in household waste.

— Skincarisma verdict
4.0 / 5 ★★★★☆

Verdict: Aknemycin Plus is a well-formulated, clinically proven prescription acne treatment that combines the antibacterial power of erythromycin with the gold-standard retinoid tretinoin in an ultra-minimal 5-ingredient formula. It excels for oily, acne-prone skin and is one of the few prescription acne treatments that is also fungal acne safe. The alcohol-based solution is not for everyone — sensitive and dry skin types may struggle with the initial irritation — and the purging phase requires patience. But for those who can tolerate it, Aknemycin Plus delivers meaningful clearing of comedonal and inflammatory acne within 9–12 weeks, with the added bonus of tretinoin's skin-resurfacing benefits. A solid choice as a second-line topical when OTC treatments have fallen short.

lightbulb What are Notable Effects & Ingredients?

Ever used a product that promised a certain effect but provided no results? It might not have contained any notable ingredients that could have been responsible for that promised effect. It doesn't matter what the marketing or packaging «promises» it can do, if it doesn't contain anything that can help - then the likelihood of it helping is low.

We help you identify key notable ingredients that have been shown to help with effects such as acne-fighting, brightening, UV-protection, wound healing & anti-aging to help you achieve your skincare goals smarter. Please note that different notable ingredients have varying levels of research behind them, some are extremely well proven yet some have mixed research in their efficacy.

question
lightbulb What is the Ingredient Safety Breakdown?

Ingredient Safety Breakdown refers to the percentage % of ingredients in different risk categories as classified by EWG (Environment Working Group) if they are available. There are almost endless cosmetic ingredients and they are one of the few organisations globally that have assigned ratings to a lot of the more commonly used ingredients which is why we reference them.

muscle Pro Tip Alert!

EWG is seen by many to be more on the alarmist side in their assignment of health ratings resulting in rating ingredients as riskier than they actually are. We recommend using this a reference point rather than a strict guide of ingredient safety and to always do further research if into ingredients that you may find suspect.
