Henry, who also notes that it "works a bit faster than salicylic acid," taking up to four weeks to show results. "Benzoyl peroxide is especially good for more inflammatory acne that is usually colonized by bacteria," says Dr. Karp, while salicylic acid does its best work on blackheads and whiteheads.
If you have blackheads and whiteheads, salicylic acid alone should work well to clear out your pores. If your acne tends to be inflammatory, such as papules and pustules, opt for benzoyl peroxide to stop outbreaks at the source. For sensitive skin, start with salicylic acid, since it's less likely to cause irritation.
The bottom line
Benzoyl peroxide and salicylic acid work differently, but they can both be helpful in treating acne. While current research supports benzoyl peroxide's effectiveness, salicylic acid may cause less side effects. You can use these two OTC medications together or separately.
Research on the chemical differences between these two acne-fighting agents has shown that salicylic acid opens the pores and has a bit of a sloughing, exfoliating effect. However, benzoyl peroxide is superior for treating acne because it has an anti-microbial effect and a better antioxidant effect.
Your treatment plan could include salicylic acid and benzoyl peroxide at the same time, but it is best to space them out to decrease your risk for peeling, redness, dermatitis and drying. Doctors suggests switching between products every night, or using one in the AM and the other in the night.
How can I slot benzoyl peroxide into my routine? “I usually recommend that it's used in the morning – with the use of a retinoid, such as tretinoin at night, which will help increase the absorption of BPO,” says Dr Sam. For the best results though, you should also look at your wider skincare routine.
By using a salicylic acid enriched wash after cleansing the skin of any remaining makeup, you are helping to rid the skin of any dead skin cell build-up allowing any nourishing products applied afterwards to absorb quicker into the lower layers of the skin and show results quicker.
1 If you're just beginning with your benzoyl peroxide treatment, start using moisturizer now, even before you notice any uncomfortable dryness. You may be able to stave off the worst of it.

For acne prone or oily people, this hydration “tricks” oil glands into making less oil. Products containing Niacinamide are fantastic to pair with dehydrating ingredients like benzoyl peroxide, salicylic acid, or retinols to balance the skin.
Yes, you can use benzoyl peroxide and niacinamide at the same time. In fact, many experts suggest teaming highly potent and drying ingredients, such as benzoyl peroxide with hydrating ones, such as niacinamide. With benzoyl peroxide penetrating further into the skin, it can sometimes cause some irritation and dryness.
Apply a small amount of the medication, gently rub into the area, and then shave. If you are using a cream, foam, lotion, or gel, apply it to the affected area as directed, usually once or twice a day. Before applying each dose, gently wash the affected area with a mild cleanser, then pat dry.

Often found spot treatments and acne-focused skincare products, benzoyl peroxide is generally okay to use either in the morning or night, with one exception. "Benzoyl peroxide can be used during the daytime, but is often combined into formulations with other acne-fighting retinoids.
If you use a product containing benzoyl peroxide, it is best to wait until this product has been fully absorbed before applying a serum and/or moisturiser. Benzoyl peroxide works best when it has the chance to absorb into the skin first. This only takes a few seconds.
Consider any medicines and skin care products you already use. Some may make your skin more sensitive, such as prescription retinoid creams or products containing retinol or benzoyl peroxide. Exfoliating while using these products can trigger acne breakouts or excessive dryness.
It works by penetrating and dislodging the gunk (sebum) in your pores, so that it's no longer trapped — resulting in a lower chance of triggering an acne breakout." When you combine salicylic with a moisturizer, you're essentially chemically exfoliating your skin while also giving it the hydration it needs to avoid—you ...
