Azelaic acid works by killing bacteria that can cause acne and rosacea. It also helps to reduce inflammation and redness. Azelaic acid can also help to unclog pores and reduce the appearance of fine lines and wrinkles. Azelaic acid is a safe and effective treatment for a variety of skin conditions. It is available in over-the-counter creams and gels. It is typically used once or twice a day.
Antibacterial
Azelaic acid is effective against a variety of bacteria, including Propionibacterium acnes, the bacteria that causes acne. Azelaic acid works by inhibiting the growth of bacteria and preventing them from producing toxins. This helps to reduce inflammation and the development of new acne lesions.
Anti-inflammatory
Azelaic acid has anti-inflammatory properties that can help to reduce the redness and swelling associated with acne and rosacea. It does this by inhibiting the production of inflammatory cytokines, which are molecules that promote inflammation.
Comedolytic
Azelaic acid is comedolytic, which means that it helps to unclog pores. It does this by dissolving the bonds that hold dead skin cells together, allowing them to be shed more easily. This helps to prevent the formation of comedones, which are the small bumps that can lead to acne.
-
Exfoliation
Azelaic acid is a gentle exfoliator that can help to remove dead skin cells and promote cell turnover. This can help to improve the appearance of acne and rosacea, and can also help to prevent future breakouts.
-
Antibacterial
In addition to its comedolytic properties, azelaic acid is also antibacterial. This helps to kill the bacteria that can cause acne, and can also help to prevent the formation of new breakouts.
-
Anti-inflammatory
Azelaic acid has anti-inflammatory properties that can help to reduce the redness and swelling associated with acne and rosacea.
Overall, azelaic acid is a safe and effective treatment for acne and rosacea. It is available in over-the-counter creams and gels, and is typically used once or twice a day.
Keratolytic
Azelaic acid is a keratolytic, which means that it helps to break down the bonds between dead skin cells. This allows the dead skin cells to be shed more easily, which can help to improve the appearance of acne and rosacea. Azelaic acid can also help to unclog pores and prevent the formation of new breakouts.
Depigmenting
Azelaic acid has depigmenting properties, which means that it can help to fade dark spots and hyperpigmentation. It does this by inhibiting the production of melanin, the pigment that gives skin its color. Azelaic acid is effective in treating a variety of skin conditions that cause hyperpigmentation, including acne, rosacea, and melasma.
-
Inhibition of Tyrosinase
Azelaic acid works by inhibiting tyrosinase, an enzyme that is involved in the production of melanin. By inhibiting tyrosinase, azelaic acid can help to reduce the production of melanin and fade dark spots.
-
Exfoliation
Azelaic acid is also a mild exfoliator, which means that it can help to remove dead skin cells. This can help to improve the appearance of dark spots and hyperpigmentation by removing the top layer of discolored skin cells.
-
Anti-inflammatory
Azelaic acid has anti-inflammatory properties, which can help to reduce the inflammation that can contribute to hyperpigmentation.
Overall, azelaic acid is a safe and effective treatment for hyperpigmentation. It is available in over-the-counter creams and gels, and is typically used once or twice a day.
Antioxidant
Azelaic acid is an antioxidant, which means that it can help to protect the skin from damage caused by free radicals. Free radicals are unstable molecules that can damage cells and DNA, leading to premature aging and the development of skin conditions such as acne and rosacea. Azelaic acid can help to neutralize free radicals and prevent them from damaging the skin.
-
Protection from environmental damage
Azelaic acid can help to protect the skin from damage caused by environmental factors such as UV radiation and pollution. These factors can generate free radicals that can damage the skin’s DNA and lead to premature aging. Azelaic acid can help to neutralize these free radicals and prevent them from damaging the skin.
-
Reduction of inflammation
Azelaic acid has anti-inflammatory properties that can help to reduce the redness and swelling associated with acne and rosacea. It does this by inhibiting the production of inflammatory cytokines, which are molecules that promote inflammation.
-
Improvement of skin tone and texture
Azelaic acid can help to improve the skin’s tone and texture by reducing the appearance of fine lines, wrinkles, and hyperpigmentation. It does this by promoting the production of collagen and elastin, which are proteins that give the skin its strength and elasticity.
Overall, azelaic acid is a safe and effective antioxidant that can help to protect the skin from damage and improve its appearance. It is available in over-the-counter creams and gels, and is typically used once or twice a day.
Tips for Using Azelaic Acid
Azelaic acid is a safe and effective treatment for a variety of skin conditions, including acne, rosacea, and hyperpigmentation. Here are a few tips to help you get the most out of azelaic acid:

Scientific Evidence and Case Studies
Azelaic acid has been studied extensively for its efficacy in treating a variety of skin conditions, including acne, rosacea, and hyperpigmentation. Here is an evidence summary of key studies:
Acne
A study published in the Journal of the American Academy of Dermatology found that azelaic acid was effective in reducing the number of acne lesions in patients with mild to moderate acne. The study participants applied a 20% azelaic acid cream to their face twice a day for 12 weeks. The results showed that the azelaic acid cream was significantly more effective than the placebo in reducing the number of acne lesions.
Rosacea
A study published in the British Journal of Dermatology found that azelaic acid was effective in reducing the symptoms of rosacea, including redness, swelling, and inflammation. The study participants applied a 15% azelaic acid cream to their face twice a day for 12 weeks. The results showed that the azelaic acid cream was significantly more effective than the placebo in reducing the symptoms of rosacea.
Hyperpigmentation
A study published in the Journal of Cosmetic Dermatology found that azelaic acid was effective in reducing the appearance of hyperpigmentation, including melasma and post-inflammatory hyperpigmentation. The study participants applied a 20% azelaic acid cream to their face twice a day for 12 weeks. The results showed that the azelaic acid cream was significantly more effective than the placebo in reducing the appearance of hyperpigmentation.
Overall, the scientific evidence suggests that azelaic acid is a safe and effective treatment for a variety of skin conditions, including acne, rosacea, and hyperpigmentation.
