When it comes to skincare, you’ve probably heard a lot about azelaic acid and salicylic acid. These two ingredients are often used to treat acne and other skin concerns, but how do they compare? And can you use them together?
In this article, we’ll break down the benefits, differences, and how to incorporate both acids into your skincare routine.
What is Azelaic Acid?
Azelaic acid is a naturally occurring dicarboxylic acid found in grains like wheat, barley, and rye. It’s a multi-functional skincare ingredient used to treat a variety of skin concerns.
In skincare, azelaic acid is prized for its anti-inflammatory, anti-bacterial, and exfoliating properties, making it an effective treatment for acne, rosacea, and pigmentation issues.
Azelaic acid works by:
- Penetrating the skin: It helps unclog pores by gently exfoliating the surface, promoting healthy skin turnover.
- Fighting bacteria: It targets Propionibacterium acnes, the bacteria responsible for acne formation.
- Reducing pigmentation: It inhibits melanin production, helping to lighten dark spots and even out skin tone.
Because of its gentle, yet powerful nature, azelaic acid is often recommended for people with sensitive skin, as it causes fewer side effects than some harsher acids like glycolic or salicylic acid.
Key Benefits of Azelaic Acid
-
Reduces Acne and Rosacea Symptoms: Azelaic acid helps reduce acne breakouts by killing acne-causing bacteria and soothing inflammation. It’s also highly effective in treating rosacea, helping to reduce the redness and bumps associated with this skin condition.
-
Fights Pigmentation Issues: Azelaic acid is particularly beneficial for tackling hyperpigmentation, melasma, and dark spots. It works by inhibiting the production of excess melanin, which helps brighten the skin and fade discoloration over time.
-
Suitable for Sensitive Skin: Unlike stronger exfoliating acids, azelaic acid is gentle on the skin, making it an excellent choice for those with sensitive skin or conditions like rosacea. It helps reduce redness and irritation, providing relief for inflamed skin.
What is Salicylic Acid?
Salicylic acid is a type of beta hydroxy acid (BHA), which is oil-soluble, meaning it can penetrate deep into your skin, specifically targeting the pores. It’s derived from the bark of willow trees and is widely used in skincare products, especially for treating acne and oily skin.
Salicylic acid works by:
- Penetrating pores: Unlike water-soluble acids, salicylic acid can dissolve in oil, allowing it to enter and clear clogged pores filled with excess oil, dirt, and dead skin cells.
- Exfoliating: It exfoliates the skin’s surface by sloughing off dead skin cells, promoting the growth of new skin.
- Reducing inflammation: It has anti-inflammatory properties that help calm the skin and reduce the redness and swelling associated with acne and irritation.
Thanks to its ability to go deep within pores, salicylic acid is a go-to for people with oily and acne-prone skin.
Key Benefits of Salicylic Acid
-
Deeply Penetrates Pores: Salicylic acid is known for its ability to penetrate deep into the pores to clear out excess oil, dirt, and bacteria. This is especially helpful for preventing clogged pores, which are a leading cause of acne and blackheads.
-
Excellent for Blackhead and Acne Prevention: By clearing debris from within the pores, salicylic acid helps prevent blackheads and acne. It targets the root cause of acne by reducing oil buildup and preventing future breakouts.
-
Exfoliates the Skin to Improve Texture: Salicylic acid exfoliates the skin gently but effectively, removing dead skin cells and encouraging cell turnover. This helps to improve skin texture, smooth rough patches, and make the skin look brighter and more even.
How Do Azelaic Acid and Salicylic Acid Work Together?
Comparison of Mechanisms
Azelaic Acid and Salicylic Acid are both powerful skincare ingredients, but they work in different ways to address various skin concerns.
-
Azelaic Acid primarily targets inflammation, pigmentation, and skin tone. It helps reduce redness, calm irritation, and lighten dark spots by inhibiting melanin production. This makes it particularly beneficial for those with rosacea, post-acne pigmentation, and uneven skin tone.
-
Salicylic Acid, on the other hand, works by targeting pore congestion, acne, and oil control. It penetrates deep into the pores to break down oil and debris, preventing blackheads, acne, and clogged pores. It also provides gentle exfoliation to help improve skin texture.
Can They Be Used Together?
Yes, azelaic acid and salicylic acid can be used together in a skincare routine, but it’s essential to follow some guidelines for safe and effective use.
Safe Use: Layering Methods
If you want to use both acids together, consider these approaches:
-
Morning vs. Night: One effective method is to use azelaic acid in the morning and salicylic acid at night. This way, both acids can work on different skin concerns without overwhelming your skin.
-
Alternate Days: If you have sensitive skin or if you’re new to these ingredients, you may want to alternate them on different days. For example, use azelaic acid on Mondays, Wednesdays, and Fridays, and salicylic acid on Tuesdays, Thursdays, and Saturdays.
Potential Benefits: Complementary Effects
When used correctly, azelaic acid and salicylic acid can complement each other and work synergistically. Here’s how:
-
Acne Control: Azelaic acid helps reduce the inflammation caused by acne, while salicylic acid clears out clogged pores and prevents future breakouts.
-
Improved Skin Texture: Azelaic acid evens out skin tone and lightens pigmentation, while salicylic acid exfoliates and improves skin texture, resulting in smoother and clearer skin overall.
Caution: Over-Exfoliation Risks
While these acids are both beneficial, overuse can lead to skin irritation. Both ingredients exfoliate the skin, so using them too often or in high concentrations can cause excessive dryness, redness, and peeling. To avoid this:
-
Start Slowly: Begin by using these acids a few times a week and gradually increase the frequency as your skin builds tolerance.
-
Moisturize Well: Always follow up with a good moisturizer to help keep your skin hydrated and prevent irritation.
Benefits of Using Azelaic Acid and Salicylic Acid Together
Clearer Skin:
When used together, azelaic acid and salicylic acid work in harmony to target key factors that contribute to skin imperfections:
- Azelaic acid helps calm inflammation and reduce redness, making it excellent for soothing acne-prone or rosacea-affected skin.
- Salicylic acid deeply cleanses the pores, clearing away excess oil and debris, which helps prevent future breakouts.
By combining these two, you get the benefit of a dual-action approach to clearer skin: azelaic acid works on reducing irritation and preventing new blemishes, while salicylic acid keeps pores clear and free from clogs.
Targets Multiple Concerns:
One of the major benefits of combining azelaic acid and salicylic acid is their ability to address several skin concerns at once:
- Acne: Both acids help treat acne, but in different ways. Salicylic acid prevents new breakouts by keeping pores unclogged, while azelaic acid reduces the inflammation and redness that can result from acne.
- Pigmentation: Azelaic acid helps fade dark spots and hyperpigmentation caused by acne or sun exposure, providing a more even skin tone.
- Redness: Azelaic acid is great for calming inflammation, making it ideal for reducing redness and irritation.
- Clogged Pores: Salicylic acid acts deep within the pores, breaking down oils and dead skin cells that contribute to blackheads and breakouts.
This makes the combination especially effective for multi-tasking on a range of skin issues. Whether it’s acne scars, hyperpigmentation, or active breakouts, using both acids can help provide comprehensive skincare.
Maximized Results:
Using azelaic acid and salicylic acid together can provide maximized results for a variety of skin types, from oily to sensitive:
- For Oily Skin: The deep-cleansing properties of salicylic acid are perfect for controlling excess oil production, while azelaic acid helps reduce acne-related inflammation, offering a balanced treatment approach.
- For Acne-Prone Skin: Both acids target acne, but in different ways. Salicylic acid prevents future breakouts, while azelaic acid helps reduce the severity of existing acne and minimize scarring.
- For Sensitive Skin: While both acids are generally well-tolerated, azelaic acid is especially soothing for sensitive skin. By using it alongside salicylic acid in alternating doses, sensitive skin types can benefit without overloading the skin.
When combined, these two ingredients offer a well-rounded treatment plan for various skin concerns and skin types, delivering balanced care that maximizes results.
How to Layer Azelaic Acid and Salicylic Acid
When to Use Them:
Knowing when to apply azelaic acid and salicylic acid in your skincare routine is essential to avoid irritation and maximize their benefits. Here’s how you can incorporate both into your day:
-
Azelaic Acid in the Morning: Azelaic acid is generally well-tolerated and can be used in the morning. It works well as a gentle skin tone corrector, reducing redness and pigmentation. It also protects the skin by calming inflammation throughout the day.
-
Salicylic Acid in the Evening: Salicylic acid is best used at night. Since it’s an exfoliant and works deeply within the pores to clear out dirt and excess oil, nighttime application ensures your skin isn’t exposed to environmental pollutants or UV rays that could irritate exfoliated skin. This allows the skin to fully absorb its benefits and recover overnight.
Layering Tips:
When layering active ingredients like azelaic acid and salicylic acid, the general rule of thumb is to apply the lightest formulation first, and then layer thicker products afterward. Here’s how to do it:
- Start with a Cleanser: Choose a gentle, non-stripping cleanser to prepare the skin.
- Azelaic Acid First: If using both ingredients in the same routine, apply azelaic acid first because it usually comes in a lighter gel or serum form. Let it absorb for a few minutes.
- Salicylic Acid Next: If you’re applying salicylic acid in the evening, it often comes in a toner, gel, or liquid form, which is typically lighter than creams. Apply it after azelaic acid if you’re layering both on the same occasion.
- Finish with Moisturizer: After both active ingredients are absorbed, apply a moisturizer to keep the skin hydrated and prevent dryness or irritation.
Concentration Recommendations:
When first introducing azelaic acid and salicylic acid into your routine, it’s important to start with lower concentrations to avoid overwhelming your skin:
-
Azelaic Acid: Start with a 10% concentration (common in over-the-counter products) and monitor your skin’s response. If your skin tolerates it well, you can move up to 15%-20% formulations.
-
Salicylic Acid: Begin with a 1%-2% concentration (typically found in toners or serums) to prevent over-exfoliation and irritation. As your skin adjusts, you can increase the frequency or opt for products with higher concentrations if needed.
Which Acid Is Right for Your Skin Type?
Azelaic Acid:
Azelaic acid is a gentle yet effective active ingredient that works well for skin types that are more sensitive. Here’s why:
-
Sensitive Skin: Azelaic acid is often recommended for sensitive skin because it’s less likely to cause irritation compared to other exfoliating acids. It helps calm inflammation and reduces redness, making it suitable for skin prone to sensitivity.
-
Dry Skin: If your skin tends to be on the drier side, azelaic acid can be a great choice as it doesn’t strip moisture from the skin. It also helps promote a more even skin tone without exacerbating dryness.
-
Rosacea-Prone Skin: Azelaic acid is widely used for treating rosacea due to its anti-inflammatory properties. It helps reduce redness, bumps, and visible blood vessels, making it an ideal solution for those with rosacea symptoms.
Salicylic Acid:
Salicylic acid works wonders for oily or acne-prone skin types because of its unique properties:
-
Oily Skin: Salicylic acid is a lipophilic acid, which means it penetrates deep into the pores to dissolve excess oils and clear out blockages. This makes it ideal for oily skin types that tend to experience clogged pores and breakouts.
-
Acne-Prone Skin: Salicylic acid is a go-to ingredient for acne treatment due to its exfoliating and clearing properties. It helps reduce acne lesions and prevent future breakouts by keeping pores clear of oil and dead skin cells.
-
Congested Skin: If your skin tends to feel congested or has blackheads, salicylic acid is effective in deep-cleansing pores, improving texture, and helping to unclog pores.
Conclusion
In summary, both azelaic acid and salicylic acid offer distinct benefits for different skin concerns. Azelaic acid is perfect for reducing inflammation, redness, and pigmentation, while salicylic acid excels at clearing pores and preventing acne. By understanding your skin type and needs, you can use both acids effectively to achieve clearer, more even skin.
