Frequently Asked Questions

How long does Benzac take to work?

When applying benzoyl peroxide, it will immediately get to work on treating the visible pimples on your skin’s surface, but it will also start to go to work underneath as well. Because of this, you need to allow 8-12 weeks to see the full effect that Benzac has had on your acne. Escaping the cycle of spots is a commitment. Due to the effects of benzoyl peroxide on your skin, your acne may sometimes appear worse before it gets better — but try not to give up. This is likely to happen in the first two weeks of treatment. Try and remember that once it gets worse it is actually closer to being better.

Can I use Benzac if I have severe acne?

Severe cases of acne may need different treatments so it’s best to consult a GP or dermatologist. If you’re unsure about whether or not your acne is severe, our article Acne and Pimples: Spot the Difference breaks down the different types of acne that exist.

Should I use Benzac if I don’t have acne?

Yes, you can! If you don’t suffer from acne then you can use our cleansers, scrubs and moisturiser products. These products don’t have the active ingredients that are specific to treating mild acne, but are effective for maintaining clear and hydrated skin. See our full line up of complementary skincare products to find out more.

Can I leave Benzac on overnight?

Yes, you can. When you first start using Benzac AC treatment gels it’s recommended that for the first three days, you only leave the treatment on for a couple of hours and wash it off. This ensures that you are getting your skin used to benzoyl peroxide. After three days of no redness, you can then apply Benzac in the evening and leave it on overnight. Make sure that you are applying a moisturiser after the treatment product to prevent any dryness from occurring.

Can I use Benzac if I have sensitive skin?

Everyone is different and so is their skin. When trying a new product, it’s always best to do a patch test first. We recommend that you try applying a little bit of the product on the area behind your ear. This will help determine if you are sensitive to the product and active ingredients before you use it on your face. If you have sensitive skin, we recommend that you consult your healthcare professional.

Can I use Benzac if I have oily skin?

Yes, you can. Benzac is great for oily skin. The unique acrylate copolymer (AC) technology that is found in our Benzac treatment gels works to clear up excess oil (sebum), whilst ensuring that the benzoyl peroxide doesn't dry out your skin completely.

Can I use Benzac if I have dry skin?

Yes, you can. However, it’s important to remember that benzoyl peroxide is naturally drying and can cause your dry skin to become even drier. The best way to combat this is to ensure that you moisturise every time you use a treatment. It’s important that you use a moisturiser that won't clog your pores and boosts your skin's hydration. Our Daily Facial Moisturiser is an amazing product to help you reduce your dry skin and treat your acne. See our line of products designed for dry skin.

I am allergic to benzoyl peroxide. Can I still use Benzac?

All of our treatment products in the Benzac range contain benzoyl peroxide. Unfortunately, if you’re allergic to benzoyl peroxide, you will not be able to use the Benzac treatment products. If you’re unable to use benzoyl peroxide, you can still benefit from our complementary skincare products such as the Benzac Blackheads Facial Scrub or our Daily Facial Moisturiser. See our full line up of complementary skincare products to find out more.

Does Benzac remove dark spots?

The active ingredient in Benzac is benzoyl peroxide, in some cases this can cause slight lightening of your skin if applied to the same area for extended amounts of time. In terms of removing dark spots, that is not what Benzac is for and so we would not recommend using it for dark spot removal.

Is Benzac tested on animals?

We are happy to inform you that all formulations within Benzac have not been tested on animals. However, it is important to understand that the active ingredient found in the Benzac AC range, benzoyl peroxide, has been used extensively in the pharmaceutical industry for over 30 years. During that time, it was mandatory to test human health products on animals and therefore the active ingredient benzoyl peroxide, would have been tested on animals to ensure its safety for use in humans.

Should I use 2.5%, 5% or 10% strength acne gel?

When using benzoyl peroxide, we recommend that you start at 2.5% and build up over time as needed. Do not start at the 5% or 10% formulations. See our full line up of treatment strength options to find out more. 

I’m using Benzac and my skin is drying out. What should I do?

Slight tightness or mild redness may indicate that your skin is adjusting to the active ingredients in Benzac. This is a common occurrence and may last up to two weeks. If you experience dryness while using Benzac, ensure that you are using the Benzac Daily Facial Moisturiser after applying the Benzac AC treatment gels. This will help to reduce the drying nature of benzoyl peroxide on your skin.

What should do if my skin becomes irritated after using Benzac?

Given the nature of benzoyl peroxide, you may experience some minor irritation or dryness. In most cases, this will go away as your skin becomes used to the treatment. If it doesn't, we recommend that you see your GP or dermatologist. A non-comedogenic moisturiser (one that won't clog your pores) is an effective way to help manage any dryness that may occur. See our range of moisturisers to help combat dry and irritated skin.

Can I use the treatment gel by itself or do I need to use the other products at the same time?

It’s important that if you are using a treatment product with an active ingredient, such as benzoyl peroxide, that you are also using a quality cleanser and moisturiser. Get into a routine and apply your cleanser, treatment and moisturiser morning and night for consistency and to help improve your results.

How often should I exfoliate?

Exfoliating is an important part of your acne-fighting skincare routine. We recommend that you treat your skin gently and only exfoliate a maximum of twice a week as doing it more frequently can further irritate and inflame the skin. Get all the facts about exfoliation in our article Should I Exfoliate if I Have Acne-Prone Skin?

Should I be moisturising if I have oily skin?

Use a moisturiser every single day, both morning and night. There are no two ways about it, benzoyl peroxide will dry your skin — even if it tends to be oily. The best way to counteract this is to use a non-comedogenic moisturiser every day. If you're just beginning with your benzoyl peroxide treatment, start using moisturiser now, even before you notice any uncomfortable dryness. See our range of moisturisers to help combat oily skin.

What’s the difference between acne and pimples?

Acne scarring is caused by severe acne, but it can also be caused by picking, popping and/or over exfoliating. Although tempting, do not pick or pop your acne.

The best thing you can do to keep scarring at bay is to effectively treat mild acne early with a therapeutic treatment product, such as our Benzac AC treatment gels. If you are suffering from moderate to severe acne and are concerned about acne scarring, then please seek medical advice from a health professional.
