There is a ton of research supporting the benefits of azelaic acid and the effects it can have on the skin. Although it is still one of the lesser-known acids, it has surged in popularity in recent years and many of us have realized that this powerful ingredient is what we are missing from our daily skincare routines.
On the other hand, BHAs, especially salicylic acid, have become a key ingredient in the fight against problem skin. It is well known for its efficacy and effectiveness in fighting pimples, blemishes, and acne. This can come with some side effects such as dry skin, itching, and mild irritation.
If you are a little confused about these ingredients and don’t know if they are a good fit for your daily routine, here is a quick summary.

Now that you’ve had a brief look at these ingredients, let’s take a closer look at whether or not you can mix them.
Can BHAs and Azelaic Acid be used together?
Yes, BHAs and Azelaic Acid are considered safe to use together. To avoid unwanted skin reactions, it’s best not to layer them. The perfect combination of these powerful ingredients can combat a variety of skin concerns, such as breakouts, blemishes, uneven skin tone, signs of aging, and dull complexion. Try to use the ingredients and leave enough time between applications, such as B. 30 minutes, to ensure that the pH of the skin can balance and stabilize again. Mixing can cause irritation, increased sensitivity, rashes, and redness.

What shouldn’t be mixed with BHAs?
There are some ingredients that should not be mixed with BHAs, for example: B, Salicylic Acid.
- Do not mix with AHAs – Using too many acids can cause the skin to over-exfoliate, often stripping it of important sebum. If the skin barrier does not have the right amount of sebum, it will produce too much sebum, leading to more breakouts, spots, and acne.
- Do not mix with retinol – Both ingredients are very potent and should not be used together as this can cause serious side effects and skin irritation.
- Do not mix niacinamide with AHAs and BHAs as the different pH levels can cause redness, for example niacinamide has a pH of 5-7. This can cause the acids to not work as effectively and not achieve their effects.
Can Azelaic Acid and Salicylic Acid be mixed?
No, you should not mix azelaic acid and salicylic acid as this can increase the chances of skin irritation. This is because azelaic acid works on the outer layer of the skin, while salicylic acid can penetrate deeper into the skin. This can lead to too much irritation on the face, causing itching, redness, sun sensitivity, and general discomfort.
If you want to use azelaic acid and salicylic acid in your skincare routine, it is best to apply them alternately to the skin. You can use each active ingredient in your evening routine, or you can use azelaic acid in the morning and salicylic acid in the evening. Be sure to apply an SPF of 30 or higher every day to protect your skin from UV rays.
Is Azelaic Acid an AHA or BHA?
Surprisingly, it is neither an AHA nor a BHA. It occurs naturally in the skin and is derived from grains such as wheat, rye, and barley. This form of yeast is used in many skincare products. Azelaic acid still provides similar results and has a positive impact on the skin by removing dead skin cells, clearing impurities from the complexion, and providing an overall improved effect.
Where to Use Azelaic Acid Daily?
If your skin has developed a tolerance to azelaic acid, you can use some azelaic acid-rich products in your daily routine. The most popular formulas are cleansers and exfoliating toners. These products are best for first introducing azelaic acid into your routine because they rinse away from the skin, preventing over-irritation. Using a serum with hyaluronic acid after a cleanser or toner can combat dryness and lock moisture into the skin, keeping it hydrated and comfortable.
Can I use azelaic acid on wet skin?
Not really, as the amount of azelaic acid in formulas like serums and creams usually requires a prescription, and applying it to wet skin can actually cause skin irritation.
