Azelaic Acid: The Active Ingredient for Problematic Skin
Azelaic acid is a multi-talented ingredient frequently recommended in dermatology for rosacea, acne, and melasma. What makes it special: it simultaneously has antibacterial, anti-inflammatory, and brightening effects - without irritating the skin like other acids.
In our range, you'll find azelaic acid in the mesoestetic cosmelan 2 Cream - part of the professional depigmentation program that we use in our cosmetic studio in Cologne for melasma and stubborn pigment spots. The mesoestetic Mesoprotech Melan 130 combines azelaic acid with SPF 130+ for the most intense sun protection after brightening treatments. The ZO Skin Health Retinol + Blemish Complex uses azelaic acid together with retinol to combat blemishes and pigment spots.
Dr. Niels Freitag particularly recommends azelaic acid to clients who are sensitive to salicylic acid or retinol. It has less irritant potential and can still effectively work against blemishes and pigmentation.

Frequently asked questions about azelaic acid
What does azelaic acid help with?
Azelaic acid can help with blemishes (antibacterial effect), hyperpigmentation (inhibits melanin production), redness and rosacea (anti-inflammatory), and acne scars (smoothes skin texture). It is one of the few active ingredients that can address multiple skin problems simultaneously.
Is azelaic acid better tolerated than salicylic acid?
Yes, for most skin types. Azelaic acid is less irritating and less drying. Especially for rosacea-prone skin that reacts sensitively to BHA, azelaic acid is often the better choice. However, for pure pore problems without redness, salicylic acid can be more effective.
Can I use azelaic acid during pregnancy?
Azelaic acid is considered one of the few active ingredients in dermatology that is also classified as safe during pregnancy. Nevertheless, please consult your doctor before introducing new active ingredients during pregnancy.
How long does it take for azelaic acid to work?
First improvements in blemishes after 4-6 weeks. For hyperpigmentation and rosacea, it takes 8-12 weeks for visible results. Azelaic acid is not an instant active ingredient, but it is sustainable and gentle.
Morning or evening to use azelaic acid?
Both are possible. Azelaic acid is not UV-sensitive like retinol. In practice, many customers use it in the evening (along with the rest of their skincare routine) and vitamin C + sunscreen in the morning.
