What is azelaic acid recommended for?
1. Patients with acne or damaged skin barrier:
Due to improper skin care and treatment methods when treating acne, patients may have damaged skin barrier.
For acne patients who cannot tolerate retinoic acid drugs (such as retinoic acid cream, adapalene gel), azelaic acid is a good choice. Azelaic acid has good safety and tolerance, and the adverse reactions are very mild. Only 1% to 5% of patients will experience mild tingling, slight burning, itching and redness, which generally subside on their own. Moreover, its chemical exfoliation is weak and can also be used on sensitive skin. Azelaic acid has the highest safety level among acne drugs and is a good choice.
2. Patients with more brown and brown acne marks:
In addition to acting on acne, azelaic acid can also effectively lighten brown and brown acne marks. Therefore, it is very suitable for patients with acne and more acne marks. People with darker skin are more likely to form pigmentation, so it is more suitable for acne treatment for this group of people.
3. For patients with acne and rosacea who need long-term treatment:
Azelaic acid is a safe organic acid without the side effects of antibiotic resistance. It can be used for a long time (>6 months) for chronic and recurrent skin diseases such as acne and rosacea. It is not photosensitizing and can be used during the day.
The study found that there was no significant difference in the levels of azelaic acid in plasma and urine before and after topical application of azelaic acid cream on the skin, and it is non-toxic when used topically.
