Browse all skincare products that contain benzoyl peroxide now in our comprehensive DermaDB database

Benzoyl peroxide is a popular ingredient in acne treatments due to its ability to target and eliminate bacteria that causes breakouts.

In addition, niacinamide has anti-inflammatory properties that can help calm redness and irritation, making it suitable for sensitive or acne-prone skin types.

 

How does benzoyl peroxide help improve skin appearance?

When applied to the skin, benzoyl peroxide can cause a mild peeling effect, which can help to unclog pores and reduce the appearance of blackheads and whiteheads. Additionally, it has an exfoliating effect that can help to smooth and improve the texture of the skin. However, benzoyl peroxide can also cause dryness, redness, and irritation, especially when used in high concentrations or on sensitive skin.

 

What is the difference between benzoyl peroxide and retinoids for managing acne?

Benzoyl peroxide and retinoids are both effective in managing acne, but they work in different ways:

• Benzoyl peroxide is an antibacterial agent that helps to kill the bacteria that causes acne. It also helps to reduce inflammation and unclog pores.
• Retinoids, on the other hand, work by increasing cell turnover, which helps to prevent clogged pores and reduce inflammation. They can also help to improve the appearance of acne scars.

While benzoyl peroxide is generally recommended for mild to moderate acne, retinoids are often used for more severe cases.

 

Can I combine benzoyl peroxide with other active ingredients?

Benzoyl peroxide is an oxidising agent and generally can't be used at the same time as many other active ingredients. It will degrade other ingredients if they are sensitive to oxidation, thus rendering them ineffective. Check the list below to find out which ingredients can be used in combination with benzoyl peroxide:

• Benzoyl peroxide + Adapalene = YES
• Benzoyl peroxide + Microsphere Retinoid = MAYBE
• Benzoyl peroxide + Any other retinoid = NO
• Benzoyl peroxide + Vitamin C = NO
• Benzoyl peroxide + Azelaic acid = NO

It may be possible to use benzoyl peroxide and other ingredients at different times of the day - for example benzoyl peroxide in the morning and a retinoid in the evening. However this can increase the risk of skin irritation and dryness so care must be taken when combining these ingredients.

What should I keep in mind when using benzoyl peroxide?

It is important to note that benzoyl peroxide can cause skin irritation, so it is important to use them as directed and to talk to a dermatologist if you experience any negative side effects.

To minimize these side effects, it is recommended to start with a low concentration and gradually increase the frequency of use over time. It is also important to follow up with a moisturizer to help replenish the skin's natural moisture barrier.
