Benzoyl Peroxide vs Salicylic Acid: Which One Is Best For Acne?

Salicylic acid and benzoyl peroxide represent two common acne remedies. However, the debate between benzoyl peroxide vs salicylic acid comes down to the type of acne you're dealing with:

  • Benzoyl peroxide targets acne-causing bacteria and is most effective against red, inflamed acne and whiteheads.
  • Salicylic acid aids exfoliation to eliminate dead cells that congest pores, making it useful for rough, bumpy breakouts with minimal redness.


    In this article, we’ll discuss salicylic acid and benzoyl peroxide acne treatments, explaining how these ingredients combat acne, their potential side effects, and when to opt for one over the other.


    Benzoyl Peroxide vs Salicylic Acid: What’s the Difference?

    Benzoyl Peroxide's Acne-Clearing Mechanism


    Benzoyl peroxide is a quintessential topical treatment for acne. It works in two primary ways to clear breakouts:

    1. Diminishing acne-causing bacteria on the skin.
    2. Eliminating excess oil and dead skin cells from pores.

    Considered the most effective over-the-counter (OTC) acne treatment ingredient, benzoyl peroxide is a staple in numerous OTC products, ranging from cleansing bars and liquids to astringents, deodorant wipes, creams, gels, lotions, and masks. Typically used once or twice daily, benzoyl peroxide may take four to six weeks to manifest its effects.


    Salicylic Acid's Approach to Acne Treatment


    Salicylic acid works somewhat differently from benzoyl peroxide. As a beta hydroxy acid, it accelerates cell turnover rates, facilitating exfoliation. By aiding in the shedding of dead cells, salicylic acid helps prevent their accumulation within pores.

    Salicylic acid is present in numerous over-the-counter products and formulations, including cream, gel, liquid, lotion, medicated wipes or pads, ointment, and patches. Additionally, it's a sought-after ingredient for chemical peels performed at salons, skin spas, or dermatology clinics.

    Given their distinct mechanisms of action, benzoyl peroxide vs salicylic acid may offer better outcomes for specific types of acne.


    Benzoyl Peroxide

    Benzoyl peroxide proves advantageous for individuals experiencing:

    • Blackheads
    • Whiteheads
    • Red or inflamed acne
    • Back acne

    If you're dealing with papules and pustules—essentially, typical zits and whiteheads—benzoyl peroxide emerges as an excellent choice. Its effectiveness as a bacteria reducer makes it particularly beneficial for red and inflamed acne.


    Salicylic Acid

    Salicylic acid, on the other hand, is typically recommended for:

    • Comedonal acne (characterized by a bumpy texture without many red pimples)
    • Blackheads
    • Clogged pores
    • Hormonal acne

    Additionally, salicylic acid is often the first-line treatment for:

    • Young tweens experiencing the onset of acne breakouts
    • Individuals with sensitive skin or sensitivity to benzoyl peroxide


    Salicylic Acid vs Benzoyl Peroxide: Side Effects and Risks

    Both benzoyl peroxide and salicylic acid can induce irritation and slight stinging, particularly when initially used. While benzoyl peroxide side effects are generally mild, those of salicylic acid can vary from mild to severe.


    Side Effects and Risks of Benzoyl Peroxide

    Common side effects of benzoyl peroxide include:

    • Dry skin
    • Sensation of warmth
    • Flaking or peeling skin
    • Itching
    • Tingling
    • Slight stinging

    In some cases, more serious side effects may arise. Contact your healthcare provider if you experience any of the following:

    • Blistering skin
    • Burning sensation
    • Rash
    • Redness
    • Swelling


    Side Effects and Risks of Salicylic Acid

    Topical salicylic acid can lead to side effects ranging from mild to severe. Mild side effects that typically resolve include:

    • Skin irritation

    However, serious side effects may require medical attention. Contact your healthcare provider if you see any of the following:


    • Confusion
    • Diarrhea
    • Dizziness
    • Extreme tiredness or weakness
    • Rapid breathing
    • Headache
    • Hearing loss
    • Ringing or buzzing in the ears
    • Nausea
    • Vomiting


    Is It Possible to Use Benzoyl Peroxide and Salicylic Acid Together?

    There's no need to choose between one ingredient or the other. In fact, using both benzoyl peroxide and salicylic acid concurrently can enhance effectiveness.

    Numerous over-the-counter (OTC) products incorporate both benzoyl peroxide and salicylic acid. For instance, you might opt for a cleanser containing salicylic acid and then use a benzoyl peroxide lotion.

    It's important to note that the potential side effects of both benzoyl peroxide and salicylic acid are similar, including dryness, peeling, and irritation. Combining them may heighten the likelihood of experiencing these side effects, so consider reducing usage if you notice excessive dryness or irritation.


    Final Words

    The choice between benzoyl peroxide vs salicylic acid for acne treatment depends on understanding the nature of your breakouts. While benzoyl peroxide targets acne-causing bacteria and is ideal for red, inflamed acne and whiteheads, salicylic acid aids in exfoliation, making it suitable for rough and bumpy breakouts.
