From the Guidelines
Benzoyl peroxide cleansers (2.5-5%) are the most effective soap option for acne-prone skin, as they kill acne-causing bacteria and reduce inflammation, according to the latest guidelines from the Journal of the American Academy of Dermatology 1. When it comes to managing acne, the choice of soap is crucial.
- Benzoyl peroxide cleansers are strongly recommended due to their ability to target the root cause of acne, which is the overgrowth of Propionibacterium acnes (P. acnes) bacteria in the pores.
- Salicylic acid cleansers (1-2%) are also a good option, as they exfoliate the skin, unclog pores, and reduce oil production, making them an excellent choice for those with blackheads and whiteheads.
- Gentle, fragrance-free cleansers from brands like CeraVe, Cetaphil, or La Roche-Posay are suitable for sensitive acne-prone skin, as they are less likely to irritate the skin and cause further inflammation. It's essential to use these products correctly, washing your face twice daily with lukewarm water, gently massaging the cleanser in circular motions for about 30 seconds, then rinsing thoroughly and patting dry.
- Avoid harsh soaps, heavily fragranced products, and alcohol-based cleansers, as they can strip the skin's natural oils and worsen acne, as stated in the guidelines 1. Consistency is key, and it may take 4-6 weeks to see significant improvement.
- Complementing your cleansing routine with non-comedogenic moisturizers and sunscreen can help maintain skin health while treating acne, reducing the risk of scarring and hyperpigmentation.

From the Research
Best Soap for Acne-Prone Skin
To determine the best soap for acne-prone skin, it's essential to consider the ingredients and their effects on acne.
- Benzoyl peroxide is a widely used topical agent for acne, with potent antibacterial and mild anti-inflammatory and comedolytic effects 4.
- A study found that benzoyl peroxide in a 10% urea vehicle gel or cream and cleanser was effective and well-tolerated for the treatment of symptoms related to acne vulgaris 5.
- Moisturizers can also contribute to improving signs and symptoms of acne, with many containing anti-inflammatory properties, such as salicylic acid, benzoyl peroxide, and retinol 6.
- A neglected aspect in the management of acne is degreasing the skin, which can be achieved by washing with a soap like Neutrogena acne cleansing soap, followed by the application of a benzoyl peroxide preparation 7.
- A three-step acne system containing solubilized benzoyl peroxide was found to be an effective antibiotic-free acne treatment, with comparable reductions in inflammatory lesions and significantly greater reductions in noninflammatory lesions compared to benzoyl peroxide/clindamycin 8.
Key Ingredients to Look for in a Soap for Acne-Prone Skin
- Benzoyl peroxide: effective against acne due to its antibacterial and anti-inflammatory properties 4, 5, 8.
- Urea: helps to moisturize the skin and enhance the efficacy of benzoyl peroxide 5.
- Salicylic acid: found in some moisturizers and acne treatments, with anti-inflammatory properties 6.
- Dimethicone and/or glycerin: commonly found in moisturizers for their moisturizing properties 6.
Considerations for Choosing a Soap for Acne-Prone Skin
- Look for a soap that contains benzoyl peroxide, as it is a widely used and effective ingredient against acne 4, 5, 8.
- Consider a soap that also contains urea, as it can help to moisturize the skin and enhance the efficacy of benzoyl peroxide 5.
- Be aware of other ingredients that may be beneficial for acne-prone skin, such as salicylic acid and dimethicone/glycerin 6.
