1
Use this medicine once or twice daily as advised by your doctor. Start with once daily if your skin is sensitive.

If your skin becomes dry, apply a gentle, non-comedogenic moisturizer after washing.
5
Avoid using other harsh skin products, such as scrubs or alcohol-based toners, while using this medicine.
6
Protect your skin from excessive sun exposure. Use a broad-spectrum sunscreen when going outdoors.

🔬 How This Medicine Works (Pharmacology)

Pharmacokinetics

AbsorptionAzelaic acid is poorly absorbed through intact skin. When applied topically, only a small fraction (approximately 4% of the applied dose) is absorbed systemically. The soap formulation is rinsed off, which further limits absorption.
DistributionNot established from the available information. Because systemic absorption is minimal, distribution to body tissues is not clinically significant.
Protein BindingNot established from the available information. Azelaic acid is approximately 20-25% bound to plasma proteins when it reaches the bloodstream, but this is not clinically relevant for topical use.
MetabolismNot established from the available information. Azelaic acid is not significantly metabolized in the skin. Any absorbed azelaic acid is excreted unchanged in the urine.
Half-LifeNot established from the available information. The elimination half-life of azelaic acid after topical application is not well defined because systemic absorption is minimal.
ExcretionNot established from the available information. Any azelaic acid that is absorbed is excreted unchanged in the urine.
BioavailabilityNot established from the available information. The bioavailability of azelaic acid from this soap formulation is expected to be very low due to poor skin penetration and rinsing off.
Onset of ActionImprovement in acne may be noticed after a few weeks of regular use. The full benefit may take 4 to 8 weeks.
Peak Plasma TimeNot established from the available information. Plasma levels are negligible after topical application.
Duration of ActionThe effect of each use lasts until the next washing, as the product is rinsed off. Continuous use is needed to maintain benefit.

How It Works

This medicine works through the action of azelaic acid, which has several effects on the skin. It reduces the growth of Cutibacterium acnes, the bacterium that plays a key role in acne. It also helps to normalize the shedding of skin cells inside hair follicles, preventing them from becoming blocked and forming blackheads and whiteheads. Additionally, azelaic acid has mild anti-inflammatory properties that help to calm redness and swelling around acne spots. The soap base helps to cleanse the skin, removing excess oil and dirt that can contribute to acne.

Mechanism Steps

1
Antibacterial action: Azelaic acid penetrates the skin and reduces the growth of Cutibacterium acnes by disrupting the bacterial cell wall and inhibiting protein synthesis.
2
Normalization of keratinization: It helps to regulate the shedding of dead skin cells inside hair follicles, preventing the formation of comedones (blackheads and whiteheads).
3
Anti-inflammatory effect: Azelaic acid reduces the production of inflammatory substances in the skin, which helps to decrease redness and swelling around acne lesions.
4
Cleansing action: The soap base removes excess oil, dirt, and dead skin cells from the surface of the skin, complementing the effects of azelaic acid.
