Benzoyl peroxide is a well-known and widely used topical medication in skincare, particularly favored for its effectiveness in treating acne. Here are several key aspects of benzoyl peroxide in skincare:

1. Antibacterial Properties: Benzoyl peroxide is highly effective against Cutibacterium acnes (formerly Propionibacterium acnes), the bacteria that contribute to acne. It works by introducing oxygen into the pores, where this bacteria thrives, as it cannot live in an oxygen-rich environment. This reduces the bacterial count on the skin, thereby decreasing acne outbreaks.

2. Keratolytic Action: It helps to break down keratin, a protein that forms part of the skin structure. This action helps to unclog pores by clearing dead skin cells, excess oil, and other debris that can lead to acne.

3. Comedolytic Effect: Benzoyl peroxide is effective in preventing the formation of comedones (acne lesions), which include both blackheads and whiteheads. This is accomplished through its ability to decrease the cohesiveness of the epithelial cells lining the hair follicles, preventing them from clogging.

4. Anti-inflammatory Properties: Benzoyl peroxide reduces the inflammation associated with acne. It can help lessen the redness and swelling of active acne, providing a more immediate cosmetic benefit while the treatment works to clear the acne long-term.

5. Concentration Variations: It is available in various concentrations, typically ranging from 2.5% to 10%. Lower concentrations are just as effective as higher concentrations but tend to be less irritating to the skin. Choosing the right concentration and formulation (such as lotions, gels, creams, or wash-off products) depends on skin sensitivity and the severity of acne.

6. Potential Side Effects: Common side effects include dryness, redness, peeling, and irritation, particularly when first using the product or if used in higher concentrations. It's important for users to start with lower concentrations and gradually increase as needed, and to always use moisturizers and sun protection to help manage these side effects.

7. Use in Combination Therapies: Often, benzoyl peroxide is used in combination with other acne treatments, such as retinoids or antibiotics, to enhance efficacy and reduce the potential for antibiotic resistance when used with antibacterial agents.

When incorporating benzoyl peroxide into a skincare regimen, it's crucial for users to apply it only to clean, dry skin and to follow application with a non-comedogenic moisturizer to counteract potential drying effects. Furthermore, because benzoyl peroxide can bleach fabrics, users should be cautious with contact between the medication and clothing, towels, or bedding.

Water is a great solvent. It’s neutral and doesn’t provide any strong positive or negative effects. It just helps components to mix better and to transport active components.

Sodium Lauryl Sulfate is a surfactant. It helps cosmetic products to remove all the sebum and dirt from your skin. Water can't dissolve sebum on its own because sebum contains oils. Surfactants help water get into sebum and wash off all the unnecessary stuff from your skin.

The component also helps to form a nice foam. The foam allows to spread the product evenly. which is important for good cleansing.

Cetyl Alcohol is a fatty alcohol. It’s responsible for making your skin soft and improving product thickness. It makes the product easier to apply and feel richer. Though it contains the word “Alcohol” in its title, the component doesn’t belong to harmful alcohols. That’s why a product with this component can still be marked as Alcohol-free. Usually, manufacturers receive this component from coconut or palm oil.

Stearyl Alcohol creates a barrier on the skin's surface lowering the evaporation of water and making it hydrated for a longer time. This barrier helps the skin to recover after deep cleansing. It also makes the skin look smooth. Though it belongs to alcohols, it's a fatty alcohol and it doesn't make your skin dry.

Glyceryl Stearate SE is a nice moisturizing ingredient. It hydrates the upper layers of the skin and fills small wrinkles. In haircare products, it's used for making hair softer.

Glycerin is one of the most outstanding and helpful skincare components. It's used in many skincare products because it works and provides notable results. It's one of the best moisturizers. Molecules of Glycerin can absorb water and deliver it into deep layers of the skin making it hydrated.

Butylene Glycol is a very popular synthetic alcohol. It helps the product to absorb deeper and faster. It is also a solvent for other ingredients. As for the skin benefits, it helps to attract water and helps to make the skin softer.

Methylparaben is an effective preservative. It is a controversial ingredient in terms of safety. In 2006 there was a laboratory test showed that this component can increase the sun sensitivity of the skin cells. That’s why it’s a good idea to use sunscreen after you use this component.
