Salicylic acid versus benzoyl peroxide, which is better against pimples?
Salicylic acid and benzoyl peroxide are two of the most popular over-the-counter (OTC) treatments for acne. Other treatments for acne include prescription medications such as antibiotics and isotretinoin.
Acne is a common skin condition characterized by pimples, blackheads and blackheads. The condition is caused by a combination of factors, including excess sebum production, a clogged pore opening and a bacteria called Cutibacterium acnes.

What are the differences between salicylic acid and benzoyl peroxide?
Salicylic acid
Salicylic acid is a beta-hydroxy acid (BHA) that can cleanse pores and reduce inflammation. It works by removing dead skin cells from the skin and from the pores. This can help open the pores and remove the bacteria Cutibacterium acnes.
Salicylic acid is available in different concentrations, ranging from 0.5% to 20%. The concentration you should use depends on the severity of your acne. For mild acne, a concentration of 0.5% to 2% is sufficient. For moderate to severe acne, a concentration of 2% to 10% may be needed.
Salicylic acid is effective against all types of acne, but it is especially effective against blackheads and blackheads. It can be applied to the affected skin twice a day. Possible side effects of salicylic acid include skin irritation, especially if you have sensitive skin.
Benzoylperioxide
Benzoyl peroxide is an oxidizing agent that can kill the bacteria Cutibacterium acnes. When benzoyl peroxide is applied to the skin, it is converted into benzoic acid and hydrogen peroxide. These substances work together to kill the bacteria that cause acne and reduce sebum production. Benzoyl peroxide can also help open the skin’s pores, making it easier to remove excess sebum and dead skin cells. It also works by removing dead skin cells from the skin.
Benzoyl peroxide is available in different concentrations, ranging from 2.5% to 10%. The concentration you should use depends on the severity of your acne. For mild acne, a concentration of 2.5% to 5% is sufficient. For moderate to severe acne, a concentration of 10% to 12% may be needed.
Benzoyl peroxide is effective against all types of acne, but it is especially effective against blackheads and early pimples. A study shows that benzoyl peroxide 2.5% achieves 21% complete to almost complete improvement in acne after 12 weeks.
It can be applied to the affected skin up to twice a day. Possible side effects of benzoyl peroxide include skin irritation, especially if you have sensitive skin, and it can whiten the skin.

What’s better?
Salicylic acid and benzoyl peroxide are both effective treatments for acne. The best treatment for you depends on the severity of your acne and your skin type.
Salicylic acid
Salicylic acid, a beta-hydroxy acid, is a powerful ally in the fight against mild to moderate acne, especially when it comes to blackheads and blackheads. It helps your skin by deeply cleaning the pores and preventing the accumulation of dead skin cells. This deep cleansing will smooth out your skin texture and, if you use it regularly, you can really notice a difference in how much acne you have. Salicylic acid also has the benefit of being anti-inflammatory, meaning it can help reduce the redness and swelling of acne. This makes it a good choice for anyone with skin that is prone to breakouts.
Benzoylperoxide
It’s a good option for moderate to severe acne, or if you have both blackheads and pimples.
In a 1989 study, 15 people were split into two groups. One group (1) received 2% salicylic acid for the first two weeks and 10% benzoyl peroxide for the next two weeks. The other group (2) first received benzoyl peroxide and then salicylic acid.
After two weeks, the people in the first group had fewer pimples and blackheads than the people in the second group.
After four weeks, the people in the first group who first started with salicylic acid had more blackheads than after the first two weeks. This is probably because salicylic acid is less irritating than benzoyl peroxide. As a result, people are more likely to continue using salicylic acid for longer, even if they get more blackheads.
So benzoylperoxide is more effective against pimples than salicylic acid and can give quick results.
Be careful when using
It is important to use a low concentration of salicylic acid and gradually increase it as necessary. Do not use salicylic acid and benzoyl peroxide in combination with other products that may irritate your skin, such as alcohol-containing products, vitamin A (Retinol or Tretinoin) or peels. Avoid contact with eyes, nose and lips. If you suffer from acne, it is important to consult a skin specialist. The skin specialist can help you find the best treatment for your specific situation.
Breaking news about Benzoyl peroxide March 2024
Breaking news in Time, an independent laboratory, Valisure, has discovered that benzoyl peroxide, a common acne treatment agent, can break down into benzene, a known carcinogen. This degradation is not caused by contamination, but by the chemical instability of benzoyl peroxide itself. Tests showed that many benzoyl peroxide products contain benzene levels that exceed FDA limits, especially at higher temperatures, raising concerns about the long-term safety of these acne treatments.
Benzene is harmful to both the skin and the body because it is a known carcinogen, meaning it can cause cancer. It can be absorbed through the skin and enter the bloodstream, where it can attack the bone marrow and damage blood cells, leading to blood disorders such as leukemia. Long-term or high exposure can also weaken the immune system and strain the liver, reducing the body’s ability to process and excrete other toxins.
Frequently asked questions
For which type of acne is salicylic acid most effective?
Salicylic acid is most effective at treating comedonal acne, such as blackheads and white heads. This is because salicylic acid helps exfoliate the skin and unclog pores by removing dead skin cells.
Can benzoyl peroxide be used for all skin types?
Benzoyl peroxide is powerful in treating acne, but it may be too strong for very sensitive skin types or those with dry skin. It has an antibacterial effect and can dry out the skin, meaning that individuals with sensitive or dry skin should use it with caution and may consider starting with a lower concentration. Generally, 5% is for the face and benzoyl peroxide is 10% for the body. If you experience too much skin irritation from the benzoyl peroxide, skip 1-2 days and give the skin a rest.
How quickly can you expect results when using salicylic acid for acne?
When using salicylic acid, initial improvements in acne can often be seen within a few weeks, although it may take 4 to 6 weeks to notice significant results. Consistent use is important for best results.
Can salicylic acid and benzoyl peroxide be used together in an acne treatment regimen?
Yes, salicylic acid and benzoyl peroxide can be used together in an acne treatment, but it is important to use caution to avoid excessive dryness and irritation. It is often recommended to use them at different times of the day (for example, salicylic acid in the morning and benzoyl peroxide in the evening) or to choose products that contain both ingredients in lower concentrations. It is advisable to consult a dermatologist for tailor-made advice.

Vitamin B5, also known as pantothenic acid, is a water-soluble vitamin that may play a role in reducing acne. Acne is a common skin condition caused by several factors, including hormonal changes, genetics, stress and diet. There is some evidence to suggest that vitamin B5 may help reduce acne. Below we explain how vitamin B5 works and which natural sources of this vitamin are available.
