Beta hydroxy acids (BHAs) are a type of exfoliating acid that can be used to improve the appearance of the skin. They are oil-soluble, meaning they can penetrate the pores and dissolve dead skin cells and excess oil. BHAs are often used to treat acne, oily skin, and other skin conditions.

Salicylic acid is the most common BHA. It is available in a variety of over-the-counter (OTC) and prescription products, including cleansers, toners, serums, and moisturizers. Salicylic acid can be used on all skin types, but it is especially beneficial for oily and acne-prone skin.

BHAs work by dissolving the bonds that hold dead skin cells together. This allows the dead skin cells to be washed away, revealing smoother, brighter skin. BHAs can also help to reduce inflammation and redness, and they can unclog pores.

  1. Understanding Benzoyl Peroxide

Benzoyl peroxide is an organic compound that has been used as an acne treatment for several decades. It works by introducing oxygen into the pores, effectively killing acne-causing bacteria (Propionibacterium acnes) and reducing inflammation. Additionally, benzoyl peroxide helps to unclog pores and prevent the formation of new acne lesions.

  1. Benefits of Benzoyl Peroxide

a. Antibacterial properties: Benzoyl peroxide effectively targets and kills acne-causing bacteria, helping to reduce the severity and duration of acne breakouts.

b. Exfoliating action: By promoting the shedding of dead skin cells, benzoyl peroxide helps unclog pores and prevent the formation of new blemishes.

c. Anti-inflammatory effects: Benzoyl peroxide can reduce redness and inflammation associated with acne, helping to improve the overall appearance of the skin.

  1. Practical Applications for Estheticians

a. Product selection: Benzoyl peroxide is available in various concentrations, typically ranging from 2.5% to 10%. For most clients, a lower concentration (2.5% or 5%) is sufficient to achieve desired results without causing excessive irritation. Recommend products that are specifically formulated for acne-prone skin and contain benzoyl peroxide as an active ingredient.

b. Proper usage: Instruct clients to apply a thin layer of benzoyl peroxide to clean, dry skin once or twice daily, as needed. It is essential to start with a lower frequency of application and gradually increase as the skin adjusts to the treatment. Encourage clients to be patient, as it may take several weeks to see significant improvements.

c. Moisturizing and sun protection: Benzoyl peroxide can be drying to the skin, so it is crucial for clients to use a non-comedogenic moisturizer daily. Additionally, benzoyl peroxide can increase sun sensitivity, making it essential to wear a broad-spectrum sunscreen with an SPF of at least 30 during the day.

d. Monitoring and adjusting treatment: Regularly assess your client’s skin condition and response to benzoyl peroxide treatment. If excessive irritation or dryness occurs, consider reducing the frequency of application or switching to a lower concentration product.

BHAs are generally safe for most people to use. However, they can cause some side effects, such as dryness, irritation, and peeling. If you experience any of these side effects, you may need to reduce the frequency of use or switch to a different product.

Here are some additional tips for beauty professionals and estheticians who want to help their clients with BHAs:

  • Start with a low concentration of BHA and gradually increase the concentration as needed.
  • Apply BHA to clean, dry skin.
  • Avoid using BHA on open wounds or irritated skin.
  • Use sunscreen when using BHA, as it can make your skin more sensitive to the sun.
  • If you experience any side effects, such as dryness, irritation, or peeling, reduce the frequency of use or switch to a different product.
