Salicylic Acid: What Is It, How It Works, 7 Benefits, & FAQs

For those battling acne or exploring skincare routines, searching for effective ingredients often leads to salicylic acid. This versatile compound has become a staple in many skincare products, popular for its ability to address various skin concerns. If you’re curious about incorporating salicylic acid into your regime, this guide is here to help. Learn about its benefits, usage, and how it stacks up against other treatments.

What is Salicylic Acid?

Salicylic acid is a beta hydroxy acid (BHA) renowned for its exfoliating properties and role in treating acne. Unlike alpha hydroxy acids (AHAs), which are water-soluble, BHAs are oil-soluble, allowing them to penetrate deeper into the pores. This unique property makes salicylic acid effective in breaking down sebum. This oily substance can clog pores and lead to breakouts. By removing this excess oil, salicylic acid helps reduce acne and improve overall skin texture.

How Does Salicylic Acid Work?

Dr Boey explains that salicylic acid works by exfoliating both the surface of the skin and within the pores. This process clears existing blemishes and prevents new ones from forming.

Salicylic acid’s anti-inflammatory properties soothe irritated skin, making it a well-rounded treatment option for acne-prone individuals. Its ability to reduce redness and swelling further enhances its appeal as a skincare ingredient.

7 Benefits of Salicylic Acid for Skincare

Salicylic acid has numerous benefits for the skin, making it a common ingredient in many skincare products. Some of its key benefits include:

1. Acne Treatment

Salicylic acid is a trusted ally in combating acne, particularly in mild to moderate cases. It exfoliates the skin and removes debris, helping to keep pores clear and reduce the occurrence of breakouts. The ingredient’s ability to penetrate deeply into the skin ensures that it addresses the root causes of acne rather than just the symptoms.

Additionally, salicylic acid is effective in diminishing the appearance of acne scars. Accelerating the removal of dead skin cells and promoting new cell growth helps to smooth and improve the skin’s texture, making it a go-to solution for clearer, more even-toned skin.

2. Exfoliation

Exfoliation is crucial in maintaining healthy skin; salicylic acid excels in this area. Promoting the shedding of dead skin cells reveals a fresher, more radiant complexion. Regular use of salicylic acid can significantly increase skin cell turnover rates, resulting in smoother and more even-textured skin. Dr Boey highlights that salicylic acid’s exfoliating properties enhance the absorption of other skincare products, maximising their effectiveness.

3. Blackhead and Whitehead Removal

Salicylic acid effectively treats black and whiteheads by dissolving the material clogging pores. Its oil-soluble nature allows it to penetrate and break down the buildup that causes these comedones. Regular application of salicylic acid can prevent the formation of new blackheads and whiteheads, offering a long-term solution for those struggling with these common skin conditions.

4. Oil Control

Excess oil production often contributes to acne and other skin problems. Salicylic acid helps regulate sebum production, reducing the skin’s oiliness without stripping it of essential moisture. This ingredient minimises shine and reduces the likelihood of clogged pores and subsequent breakouts by keeping oil levels in check. Salicylic acid can be a game-changer in achieving a balanced complexion for oily skin.

5. Anti-inflammatory Properties

Salicylic acid’s anti-inflammatory properties make it a soothing choice for irritated skin. It effectively reduces redness and swelling, relieving those with sensitive or acne-prone skin. By calming inflammation, topical salicylic acid supports the healing process and promotes healthier-looking skin. This quality suits individuals who experience discomfort or skin irritation from other acne treatments.

6. Prevents Future Breakouts

Regular use of salicylic acid can help prevent clogged pores and future acne formation. Maintaining clear pores and regulating oil production creates an environment less conducive to acne development. Incorporating salicylic acid into your skincare routine can lead to fewer breakouts over time, helping you achieve and maintain clearer skin.

7. Hyperpigmentation Reduction

Salicylic acid assists in fading post-inflammatory hyperpigmentation caused by acne. By promoting skin cell turnover and exfoliation, it gradually lightens dark spots and evens out skin tone. This benefit is particularly valuable for individuals with acne scars or discolouration, as it contributes to a more uniform complexion. Salicylic acid’s ability to exfoliate the skin’s surface and within the pores makes it effective in treating acne, reducing the appearance of acne scars and enhancing overall skin texture.

Side Effects of Salicylic Acid

While salicylic acid offers numerous benefits, it’s essential to be aware of potential side effects. Some individuals may experience dryness, peeling, or redness, especially when using high concentrations or applying the product too frequently. Those with sensitive skin types should approach salicylic acid cautiously, as it may irritate. It’s advisable to start with lower concentrations and gradually increase usage to minimise adverse reactions.

Who is Suitable to Use Salicylic Acid?

Salicylic acid suits individuals with oily or acne-prone skin and those seeking exfoliation and oil control. Its ability to penetrate deeply into pores makes it effective in reducing breakouts and controlling sebum production. However, it’s essential to consider your skin type and sensitivity before incorporating it into your routine. Those with dry or sensitive skin may benefit from using salicylic acid sparingly or in combination with moisturising products to mitigate potential dryness.

Additionally, salicylic acid can be beneficial in treating acne scars as it helps to exfoliate the skin, promoting the fading of scars over time. Pregnant or breastfeeding individuals should consult a professional before using salicylic acid, as it may not be recommended in certain situations.

How to Use Salicylic Acid in Your Skincare Routine

Incorporating salicylic acid into your skincare routine requires careful consideration of concentration levels and application frequency. Here’s a step-by-step guide to help you with your topical salicylic acid preparations:

1. Cleanse your face with a gentle cleanser to remove impurities and prepare your skin.
2. Apply a salicylic acid product (such as a toner or serum) to the affected areas. Start with a low concentration (0.5%-2%) and gradually increase as needed.
3. Follow up with a moisturiser to maintain hydration and prevent dryness.
4. Use sunscreen daily to protect your skin from UV damage, especially if using salicylic acid in the morning.

Avoid using salicylic acid with other exfoliants or acne treatments to prevent irritation. It’s best to apply it once daily, preferably at night, to give your skin time to adjust.

Salicylic Acid vs. Other Acne Treatments

Treatment	Function	Suitable For
Salicylic Acid	Exfoliates, unclogs pores, reduces oil	Mild-moderate acne, oily skin
Benzoyl Peroxide	Kills bacteria, reduces inflammation	Moderate-severe acne
Glycolic Acid	Exfoliates, improves skin texture	Dull, uneven skin tone

Prescription vs. Over-the-Counter Salicylic Acid

Salicylic acid is available in both over-the-counter (OTC) and prescription forms. OTC products typically contain up to 2% concentration, making them suitable for mild to moderate acne. Prescription options may offer higher concentrations for more severe cases, but they should be used under the guidance of a professional.

If you need help deciding which option is right for you, consider consulting Dr. Justin Boey, the medical director of the SOZO Aesthetic Clinic, for personalised advice regarding your skincare needs.

Is Salicylic Acid OK to Use Every Day?

Salicylic acid can be used daily, especially in lower concentrations. However, monitoring your skin’s response and adjusting usage if you experience irritation is important. Using it every other day may suit those with sensitive skin.

When to Stop Using Salicylic Acid?

If you notice excessive dryness, peeling, or irritation, consider reducing the frequency of use or temporarily discontinuing salicylic acid. It’s crucial to listen to your skin and provide it with the care it needs to maintain a healthy balance.

Why Am I Getting More Pimples After Using Salicylic Acid?

Experiencing an initial increase in breakouts after starting salicylic acid is common. This phenomenon, known as purging, occurs as the acid accelerates the shedding of dead skin cells and clears out congested pores. With continued use, this should subside, leading to improved skin clarity.

Conclusion

Salicylic acid is a valuable addition to any skincare routine, offering benefits ranging from acne treatment to hyperpigmentation reduction. By understanding its properties and how to use it effectively, you can unlock its potential for clearer, healthier skin. If you’re considering adding salicylic acid to your regimen, take the time to explore its benefits and consult with professionals for personalised guidance.
