Acne Medication Benzoyl Peroxide 5%
Product Description
Rugby Laboratories Acne Medication Benzoyl Peroxide 5% is a no-frills, greaseless treatment gel that delivers a clinical dose of 5% benzoyl peroxide to kill acne-causing bacteria, unclog pores and calm inflammatory breakouts.

β¨ Texture & Feel
Kills Acne Bacteria
5% benzoyl peroxide releases oxygen into pores, destroying the C. acnes bacteria responsible for inflammatory pimples β without breeding antibiotic resistance.
Unclogs & Decongests
Works as a keratolytic to clear out dead skin cells and excess oil, helping to break down whiteheads, blackheads and clogged pores.
Greaseless, Vanishing Formula
The odorless, colorless gel sinks in quickly and leaves a matte finish, making it comfortable for daytime spot-treating under makeup.
Minimalist 7-Ingredient Base
No fragrance, oils, parabens, silicones or sulfates β a stripped-back formula that limits the risk of irritation from unnecessary additives.
π‘οΈ Safety & Compatibility
Topical benzoyl peroxide is widely regarded as one of the lower-risk acne actives in pregnancy because only ~5% is absorbed and it breaks down into benzoic acid. Still classed as use-with-caution β always confirm with your doctor first.
Contains no fatty acids, esters or polysorbates that feed malassezia. Benzoyl peroxide can even help reduce fungal-driven breakouts.
Benzoyl peroxide is a strong oxidizer and will bleach towels, pillowcases, dark clothing and dyed hair. Use white linens and let it dry fully.
Avoid using at the same time as pure vitamin C (L-ascorbic acid) or retinol, which it can oxidize/deactivate. Alternate AM/PM instead.
Can leave skin more reactive and prone to dryness. Daily broad-spectrum SPF is essential while using this product.
Start once daily and build up. Stinging, peeling or redness can occur, especially on sensitive or compromised skin barriers.
π¬ Ingredient Breakdown
π¦ Benzoyl Peroxide 5% Proven
The single active ingredient and the star of this formula. Benzoyl peroxide reduces excess oil, kills acne-causing bacteria and clears dead skin cells, making it highly effective at unclogging pores and tackling inflammatory and cystic acne.
- Mechanism: Releases oxygen inside the pore, creating an environment in which C. acnes bacteria cannot survive.
- No resistance: Unlike topical antibiotics, bacteria do not build resistance to benzoyl peroxide.
- Metabolism: Once absorbed, the body converts it to benzoic acid which is quickly excreted in urine.
𧴠Carbomer <1% Proven
A polymer of acrylic acid whose main role is to create the smooth gel consistency and keep the benzoyl peroxide evenly suspended throughout the product.
- Function: Gel-forming and emulsion-stabilising thickener.
- Typical use level: Most products contain 1% or less, which keeps the texture light and non-piling.
𧲠Disodium EDTA Trace Proven
A chelating agent that neutralizes metal ions in the formula, helping the product stay stable and supporting the action of any preservative system.
- Role: Stabilizer that prevents trace metals from degrading the formula.
- Safety: A salt of edetic acid, recognised as safe in cosmetic use at these levels.
βοΈ Sodium Hydroxide pH Adjuster Proven
Also known as lye, sodium hydroxide is used in tiny amounts purely to adjust the pH of the gel so the benzoyl peroxide stays in its most effective range.
- Function: Buffering / pH balancing agent.
- Safety: Considered safe in the small quantities used here; only concentrated amounts are caustic.
π€ Titanium Dioxide Colorant Promising
Here titanium dioxide acts as a gentle mineral opacifier/colorant that gives the gel its neutral white tone. It is a non-irritating mineral that is well tolerated by sensitive and acne-prone skin.
- Role in this product: Cosmetic colorant rather than a sunscreen dose β do not rely on it for UV protection.
- Skin-friendly: Unlikely to sting or irritate, even on reactive skin.
7 ingredients
Active: Benzoyl Peroxide 5%. Inactive: Carbomer, Disodium EDTA, Laureth-4, Sodium Hydroxide, Titanium Dioxide, Water.
π Where It Fits in Your Routine
Apply to clean, dry skin before heavier creams. Wait a minute for it to absorb, then seal with a moisturizer. In the morning, always finish with SPF.
π How to Use
Cleanse
Wash and gently pat skin completely dry before application.
Apply a Thin Layer
Cover the affected area with a thin layer once daily to start. Build up to 1β3 times daily only if tolerated.
Moisturize
Follow with a fragrance-free moisturizer to offset dryness. Reduce to once a day if peeling occurs.
Protect
Use a broad-spectrum SPF every morning, as the skin can become more sun-sensitive.
π€ Who Is It For?
β Perfect for you if:
- You have oily or combination, acne-prone skin
- You get inflammatory pimples, whiteheads or blackheads
- You want an effective treatment on a tight budget

β Frequently Asked Questions
Topical benzoyl peroxide is generally considered one of the lower-risk acne treatments during pregnancy and breastfeeding, since only around 5% is absorbed and it is rapidly broken down into benzoic acid. That said, human data is limited, so it is still labelled use-with-caution. Always check with your doctor or dermatologist before using it while pregnant or nursing, and avoid applying it to the chest area before feeding.
Yes. The formula contains no fatty acids, esters, oils or polysorbates that feed malassezia yeast, so it is considered fungal-acne safe. Benzoyl peroxide can even help reduce fungal-driven breakouts thanks to its oxidizing, antimicrobial action.
Use them at separate times rather than layering simultaneously. Benzoyl peroxide can oxidize and reduce the effectiveness of pure vitamin C (L-ascorbic acid) and plain retinol if applied together, so use one in the morning and the other at night. It pairs more comfortably with adapalene and can be alternated with AHA/BHA exfoliants, but combining strong actives at once raises the risk of irritation β introduce slowly.
It performs best on oily, combination and acne-prone skin that experiences inflammatory pimples, whiteheads and blackheads. Dry and sensitive skin types can still use it but should apply it sparingly, less often, and pair it with a richer moisturizer to manage dryness.
Many people notice active pimples calming within the first 1β2 weeks, with clearer texture by around week 4. Dermatologists generally say benzoyl peroxide reaches its full anti-acne effect after about 8β12 weeks of consistent daily use, so stick with it before judging results.
Apply it to clean, dry skin after cleansing (and toner, if you use one) and before your moisturizer. Wait about a minute for it to absorb, then seal with a fragrance-free moisturizer. In the morning, always finish with a broad-spectrum SPF.
No. With a comedogenic rating of around 1 out of 5, an oil-free base and no pore-clogging ingredients, it is considered low-risk for clogging pores. Benzoyl peroxide actually helps clear out the dead skin cells and oil that lead to clogged pores in the first place.
Treat it as good for up to about 12 months after opening, but benzoyl peroxide naturally loses strength over time. For the most reliable results, use it within a few months of opening, always honor the printed expiry date, and store it somewhere cool and dark.
Verdict: Rugby Laboratories Acne Medication Benzoyl Peroxide 5% is a hard-working, no-nonsense acne treatment that delivers a clinical 5% dose of benzoyl peroxide in a clean, fragrance-free, fungal-acne-safe gel β at a fraction of the price of premium brands. It can be drying and the tube is small, but for oily and acne-prone skin on a budget, it offers excellent value and proven results. Pair it with a good moisturizer and daily SPF, and it earns a confident recommendation.

Understanding Simple Alcohols
Alcohol ingredients are widely used in cosmetics and come in different types. For the most part alcohols are not problematic at all. However one type of alcohols, simple alcohols can be quite drying to the skin because it evaporates very quickly. This can cause irritation which can also lead to other skin complications. These alcohols should never be used alone on your skin, but combined with other cosmetic ingredients, they are normally without issue. However, for some people with sensitive and easily irritable skin, avoiding products with these simple alcohols may be beneficial.

Understanding Silicones
If you've ever used a skincare, makeup or beauty product that's made your skin look and feel smoother tempoarily - it's likely contained Silicone. They are a popular class of ingredients found in cosmetics due to their smooth, soft, easy-to-spread and smooth properties that help creates an artificial layer/barrier on top of skin or hair (commonly found in conditioners).
For the same reasons they are popularly used, they are also commonly avoided. Anecdotally, many individuals have reported that Silicones cause/excerbate breakouts, irritation, cause a feeling of skin being unable to breathe, cause clumping of cosmetic products and find it difficult to wash off. As a result, those who find them problematic are avoiding them and increasingly, cosmetic companies are avoiding them as well.
If you have had bad experiences with Silicones in the past, or suspect they are problematic then look out for the tick on the Silicone-free label.
Disclaimer
The Silicone-free label only includes the most common Silicone ingredients that have indentified been reported by individuals that could potentially cause issues.
These include: Amodimethicone, Behenoxy Dimethicone, Bis-Aminopropyl Dimethicone, Cetearyl Methicone, Cetyl Dimethicone, Cyclomethicone, Cyclopentasiloxane, Dimethicone, Dimethicone Copolyol, Dimethiconol, Methicone, Phenyl Trimethicone, Phenyl Trimethicone, Stearoxy Dimethicone, Stearyl Dimethicone, Trimethylsilylamodimethicone.

EU Allergen-Free
EU Allergen-Free
Understanding the Identified Contact Allergens
The EU's Scientific Committee on Consumer Safety (SCCS) has identified and established 26 cosmetic ingredients that are likely contact allergens (potential to cause skin allergies) as demonstrated in clinical or epidemiological studies. The EU's SCCS have recommend cosmetic companies to disclose them on the labels if used and in cases where the concentration exceeds 0.001% in leave-on products and 0.01% in rinse-off products, then they must be labelled.
Look out for the tick on the EU-Allergen free label to know your cosmetic is free from any of the 26 identified cosmetic ingredients.
For more information regarding the EU's Scientific Committee on Consumer Safety, please visit their official website.
Disclaimer
The EU Allergen Free label is for the 26 ingredients identified by the EU SCCS and products will be only flagged if a suspected ingredient is on it's ingredient list. It is possible for cosmetics to contain one of the suspect ingredients without it appearing on the ingredient list due to it not reaching the concentration threshold to disclose it and cosmetic manufacturers choice to not disclose it.
Also note, the EU Allergen Free label is not personalized for your own allergies you may have and it does not constitute as medical advice.

Fungal Acne (Molassezia) Safe
Understanding Fungal Acne (Pityrosporum Folliculitis/Malassezia Folliculitis)
Pityrosporum Folliculitis/Malassezia folliculitis or simply known as Fungal Acne is a persistent acne-like condition that commonly responds poorly to traditional acne-treating methods. Unlike most cases of Acne where bacteria is the culprit, Fungi is the culprit of Fungal Acne (Hence the name!). There are certain classes & groups of ingredients that have been shown to promote and feed the growth of the Fungal Acne, Fungi such as fatty acids, oils, esters, polysorbates and fermented ingredients.
For more information regarding Fungal Acne, please visit Simple Skincare Science (f.c) - #3 of our Recommend Skincare Resources for an amazing comprehensive guide!
Please Read: How to use the Fungal Acne (Malassezia) Label
At SkinCarisma, we've done our best to identify as many ingredients as possible but note the fungal-free label may not be 100% accurate due to the complexconditions and combination of ingredients that malezzeria can thrive on.
Additionally, products that may contain ingredients that have shown to feed Malassezia may not neccessarily exacerbate the condition due to concentration of ingredient used in the product, this information is simply not available on the products.
As a result, please note this is only an experimental label that can be best used to possible identify problematic products you have used in the past. It is in no way a perfect identifier nor a predictor in whether or not it will exacerbate or cause fungal acne. It will continue to be worked on as more information and research comes to light.
If you find any ingredients you believe should be included, please email us at snails@skincarisma.com.
Disclaimer
Due to the lack of substantial research into this area it is very likely there are other ingredients and class/groups of ingredients that could feed Fungal Acne which have not been indentified.
The Fungal-Safe label does not constitute as medical advice. For your specific case, always consult your medical professiona such as dermatologist, physician, pharmacist, or health care provider - please read our medical disclaimer for more information.
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 Β«promisesΒ» 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.
Pro Tip Alert!
Just because a product doesn't contain any notable ingredients doesn't mean it's bad. And a product with notable ingredients (or even many) doesn't necessarily guarantee the efficacy of the product performing these effects either. There are other factors such as ingredient quality, concentration and formulation that will ultimately determine this.
Be smart and use this as just a starting point for you to make more informed and smarter choices and compare it with reviews to see if the product is right for you

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.
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.
