Vitamin C and Azelaic Acid

There seems to be a lot of conflicting information regarding which actives can and can’t be used together, and I’m interested in discussing this further. I’m prompted to explore this because I’m considering introducing azelaic acid into my morning routine, which currently includes washing with water, using vitamin C, moisturizing, and applying SPF. I’m contemplating adding azelaic acid after the vitamin C, allowing 15-30 minutes for my pH to balance out. However, I’ve heard conflicting advice about whether they can be used together. This leads me to ask: which actives are safe to use together, and which ones should be avoided?

There is a lot of uncertainty about combining skincare components, but azelaic acid and vitamin C are certainly compatible! They actually work well together: vitamin C brightens and protects your skin, while azelaic acid treats acne and uneven skin tone.

The idea is to apply vitamin C first (which is lighter) and wait 15-30 minutes before applying azelaic acid. This allows your skin time to adjust to each product.

Navigating the world of skincare actives can indeed be confusing due to conflicting information. Generally, it’s essential to consider the compatibility of actives to ensure they work effectively without causing irritation or adverse reactions. In your case, incorporating azelaic acid into your morning routine after vitamin C can be safe and effective, as long as you allow sufficient time for each product to absorb and the pH to stabilize. Azelaic acid is known for its anti-inflammatory and anti-bacterial properties, making it a suitable complement to vitamin C’s antioxidant benefits. However, it’s essential to monitor your skin’s response and adjust the frequency or order of application if any irritation occurs. When combining actives, it’s generally safe to pair ingredients with similar pH levels or complementary functions, such as vitamin C and niacinamide or hyaluronic acid and moisturizers. Conversely, some actives, like retinoids and exfoliating acids, may be too harsh to use together or require staggered application to prevent overexfoliation or irritation. Overall, it’s crucial to listen to your skin’s needs, gradually introduce new products, and consult with a dermatologist or skincare professional for personalized advice.
