Usage Note: Salicylic acid can cause dryness or peeling, so it’s important to follow up with moisturizing products. It is also best to avoid using it in combination with highly potent ingredients like high-concentration retinoids.
Benzoyl Peroxide
Function: Benzoyl peroxide is a powerful antibacterial agent that works by penetrating the pores and killing the acne-causing bacteria (P. acnes). It also helps to reduce oil production in the skin and has mild exfoliating properties, promoting the renewal of the skin’s surface.
Suitable for: Ideal for moderate to severe acne, particularly for pustular or cystic acne. It is very effective at controlling oil and treating active acne.
Usage Note: Benzoyl peroxide can cause dryness, peeling, or irritation, especially when first introduced into a skincare routine. It’s recommended to start with a lower concentration and gradually increase the frequency of use, while also using a good moisturizer.
Tea Tree Oil
Function: Tea tree oil is a natural antibacterial and anti-inflammatory ingredient that effectively kills acne-causing bacteria (such as P. acnes). It also reduces inflammation, easing the redness and pain associated with acne and promoting faster healing. Tea tree oil can help control excess oil production, preventing further clogging of pores.
Suitable for: Great for mild to moderate acne, especially for those with sensitive skin or those who prefer natural ingredients. It’s also suitable for oily skin.
Usage Note: Tea tree oil can be potent and may cause irritation if applied directly to the skin. It’s recommended to dilute it with a carrier oil or incorporate it into products designed for topical application to avoid adverse reactions.
Retinoids (Vitamin A Derivatives)
Function: Retinoids (such as retinol or tretinoin) are Vitamin A derivatives that promote skin cell turnover and regulate sebum production. They work by speeding up the skin’s natural exfoliation process, preventing clogged pores, and reducing acne. Retinoids also help improve skin texture and can be effective in reducing acne scars over time.
Suitable for: Ideal for oily and acne-prone skin, particularly for those with clogged pores or comedonal acne (blackheads and whiteheads). Long-term use can improve overall skin texture.
Usage Note: Retinoids can cause dryness, irritation, or peeling, especially during the initial stages of use. It is important to start slowly and use them primarily at night, followed by a good moisturizer. Sunscreen is a must during the day as retinoids increase skin sensitivity to sunlight.
Anti-inflammatory Ingredients
Allantoin
Function: Allantoin is a soothing and anti-inflammatory ingredient that promotes skin healing and regeneration. It works by stimulating the growth of healthy skin cells and soothing irritated or inflamed skin. Allantoin helps to calm the redness and swelling associated with acne while also improving the skin’s moisture retention, which is important for reducing irritation during acne treatment.

Additionally, it promotes wound healing, which helps to reduce scarring and hyperpigmentation associated with acne.
Suitable for: Ideal for oily, acne-prone skin, especially for those dealing with cystic acne or inflammation. Zinc is often used to manage both active acne and post-acne scars.
Usage Note: Zinc is usually well-tolerated by all skin types. Topical products containing zinc, such as zinc oxide, are typically used in acne treatments. It can be found in both spot treatments and daily skincare formulations.
Antibacterial Ingredients
Sulfur
Function: Sulfur is a natural antibacterial and keratolytic ingredient, meaning it helps to prevent acne by reducing the growth of acne-causing bacteria (such as Propionibacterium acnes or P. acnes). It also helps to exfoliate the skin by removing dead skin cells and excess oil, which can clog pores and contribute to breakouts. Sulfur is particularly effective in treating acne that is caused by bacterial infections and in reducing inflammation.
Suitable for: Best for acne-prone skin, particularly those with oily skin and mild to moderate acne. It is also effective for those with sensitive skin, as it is a gentler alternative to harsher chemical treatments.
Usage Note: Sulfur can cause dryness or irritation, especially in higher concentrations, so it’s essential to follow up with a good moisturizer. It’s often found in acne spot treatments, masks, or cleansers.
Chlorhexidine
Function: Chlorhexidine is a broad-spectrum antiseptic and antibacterial agent that works by disrupting the bacterial cell membrane, killing bacteria, and preventing infection. It is highly effective against a variety of bacteria, including the bacteria responsible for acne. Chlorhexidine is commonly used in medical-grade acne treatments and as a skin disinfectant. It also helps to reduce the risk of secondary infections in inflamed acne lesions.
Suitable for: Suitable for individuals with moderate to severe acne, especially when acne lesions become infected or prone to bacterial overgrowth. It is often used in hospital settings or clinical skincare treatments.
Usage Note: Chlorhexidine can be drying or irritating if overused, so it should be used carefully in acne treatments. It’s typically applied topically in low concentrations and in products like cleansers or toners.
Tea Tree Oil
Function: Tea tree oil is a natural antibacterial and antifungal ingredient derived from the leaves of the Melaleuca alternifolia plant. It is well known for its ability to kill acne-causing bacteria (P. acnes), while also reducing inflammation and promoting healing of inflamed acne. Tea tree oil is gentle compared to synthetic antibacterial agents and has soothing properties that make it a popular choice for mild to moderate acne.
Suitable for: Suitable for oily and acne-prone skin, especially for those who prefer natural or plant-based ingredients. It’s ideal for mild to moderate acne and works well in preventing new breakouts.
Usage Note: Tea tree oil is potent and should be diluted before use to avoid irritation. It’s often used in cleansers, spot treatments, and face masks. Make sure to patch test to avoid allergic reactions.
Moisturizing and Reparative Ingredients
Hyaluronic Acid
Function: Hyaluronic acid is a powerful humectant, meaning it attracts and retains moisture from the environment into the skin. It helps to hydrate the skin without clogging pores, making it ideal for acne-prone and oily skin. By providing deep hydration, hyaluronic acid can support the skin’s natural barrier and reduce the irritation or dryness that may occur from acne treatments (such as those with salicylic acid or benzoyl peroxide). It also promotes skin elasticity and helps to maintain a plump, youthful appearance.
Suitable for: Ideal for all skin types, especially oily and acne-prone skin. It’s particularly useful for maintaining moisture balance in acne treatments that can lead to dryness.
Usage Note: Hyaluronic acid is generally safe and well-tolerated by most skin types. It can be used in both morning and evening skincare routines and is often found in serums, moisturizers, and toners. Ensure to apply it on slightly damp skin to lock in moisture effectively.
Ceramides
Function: Ceramides are lipid molecules naturally found in the skin’s outermost layer (the stratum corneum). They play a crucial role in maintaining the skin’s barrier function by preventing moisture loss and protecting against external irritants, including acne-causing bacteria. Ceramides help restore and repair the skin’s protective barrier, which can become compromised due to acne treatments or skin conditions. This makes them an excellent ingredient for calming dry, irritated skin and promoting overall skin health.
Suitable for: Ideal for acne-prone skin, particularly for individuals who experience dryness, irritation, or a weakened skin barrier due to acne medications. They are also great for sensitive skin.
Usage Note: Ceramides are gentle and suitable for daily use in all types of acne treatments. Look for products like moisturizers, serums, and cleansers that contain ceramides to help strengthen and repair the skin’s barrier.
Collagen
Function: Collagen is a structural protein in the skin that provides firmness, elasticity, and strength. Although collagen itself does not penetrate the skin deeply, it can still help improve the appearance of the skin by promoting the regeneration of skin cells, which is especially beneficial for repairing the damage caused by acne or acne scars. Collagen helps to improve skin texture and tone, as well as enhance overall skin hydration, which can contribute to reducing the appearance of acne scars and fine lines.
Suitable for: Suitable for acne-prone skin, especially for individuals with post-acne scars or uneven skin texture. It’s ideal for those seeking to promote skin repair and firmness after acne lesions have healed.
Usage Note: While collagen in skincare products doesn’t directly increase collagen levels in the skin, it can support overall skin health and the healing process. Collagen can be found in serums, creams, and masks. Topical collagen provides surface hydration and enhances the appearance of smooth, plump skin.
Key Points in Designing Acne Treatment Skincare Formulas
1. Selection and Combination of Ingredients: Choosing the right active ingredients is critical in the formulation process. It’s essential to address various causes of acne, such as excess sebum production, clogged pores, bacterial infection, and inflammation.
Closed Comedones:
Key Ingredients: Incorporate keratolytic agents such as Salicylic Acid and Alpha Hydroxy Acids (AHAs).
Purpose: These ingredients help dissolve excess keratin and exfoliate dead skin cells, unclogging pores and preventing new comedones from forming.
Inflammatory Acne:
Key Ingredients: Use anti-inflammatory and antibacterial agents such as Licorice Extract and Tea Tree Oil.
Purpose: These ingredients reduce redness, swelling, and bacterial activity, calming inflamed acne and promoting faster healing.
Post-Acne Marks (PIH):
Key Ingredients: Include brightening agents like Niacinamide and Vitamin C.
Purpose: These ingredients help fade hyperpigmentation, improve skin tone, and promote an even complexion by accelerating skin renewal.
2. pH Balance: The pH of acne products should be appropriate, ideally between 4.5 and 5.5. A high pH may irritate the skin and cause dryness, while a low pH can compromise the skin barrier. Ingredients like salicylic acid require this pH range to function effectively while minimizing irritation.
3. Lightweight Texture
Acne-prone skin is often oily, so the texture of the formula should be lightweight and non-greasy. Common lightweight formulations include:
Water-based Formulas: Provide hydration without adding oil.
Gel Textures: Control oil production and are suitable for oily or acne-prone skin.
Light Emulsions: Contain minimal oil for hydration without clogging pores.
4. Avoid Irritating Ingredients
Some ingredients may aggravate acne-prone skin by causing irritation or inflammation. Avoid:
Alcohol: Although it disinfects, it excessively dries the skin, disrupts the skin barrier, and can worsen acne.
Artificial Fragrances and Dyes: May trigger allergies or irritation.
Harsh Exfoliating Agents: Such as abrasive scrubs, which may exacerbate inflammation.
5. Time-release Technology: For potentially irritating active ingredients (e.g., salicylic acid, benzoyl peroxide, retinoids), time-release or gradual release technology can reduce skin irritation. This allows active ingredients to penetrate slowly, minimizing discomfort while maintaining efficacy.
6. Multi-functional Design: Acne products should not only address surface issues but also focus on deep repair and long-term effects. Ingredients with combined benefits, such as anti-inflammation, oil control, antibacterial, and skin barrier repair, can work synergistically to deliver optimal treatment results.
