Azelaic acid has quickly become one of the most recommended skincare ingredients for people dealing with acne, redness, post acne marks, and uneven skin tone. However, many formulations can feel drying or difficult for sensitive skin to tolerate.

SKIN1004 Madagascar Centella Azelaic Acid 10 Ampoule takes a different approach. Instead of relying solely on azelaic acid, it combines barrier supporting and soothing ingredients to deliver effective treatment while keeping the skin comfortable. The formula contains 10% azelaic acid alongside Madagascan centella, panthenol, allantoin, and hydrating ingredients, making it suitable for beginners and experienced users alike. 

After analysing its formulation, ingredient list, and intended use, it is easy to see why this ampoule has generated excitement within the Korean skincare community.

First Impressions

The ampoule has a lightweight watery gel texture that spreads easily across the skin. Despite containing 10% azelaic acid, it does not feel heavy, sticky, or greasy.

It absorbs quickly and leaves a natural finish without noticeable residue. This makes it comfortable under moisturiser during the evening or underneath sunscreen during the day.

Unlike many stronger treatment serums, it feels more like a calming hydrating ampoule than an intensive acid treatment. I also love how it doesn’t clog my pores.

Key Ingredients

One of the biggest strengths of this serum is its balanced formulation.

10% Azelaic Acid

Azelaic acid is the star ingredient. It helps reduce excess oil production, improve skin texture, minimise congestion, and gradually fade post acne pigmentation.

It also has anti inflammatory properties, making it particularly beneficial for people with redness or blemish prone skin.

Madagascan Centella Asiatica

Centella asiatica is one of SKIN1004’s signature ingredients. It helps calm irritated skin while supporting barrier repair.

This makes the serum much easier to tolerate than many traditional acid treatments.

Panthenol

Panthenol supports hydration and helps reduce irritation. It also strengthens the skin barrier, allowing the skin to recover more efficiently.

Allantoin

Allantoin soothes discomfort while promoting healthier skin recovery. It works particularly well alongside azelaic acid by helping minimise dryness.

Hyaluronic Acid

Sodium hyaluronate provides lightweight hydration that helps prevent tightness after application.

Together, these ingredients create a treatment serum that targets blemishes without compromising skin comfort. 

Performance

The serum focuses on gradual improvement rather than dramatic overnight results.

With consistent use, it helps reduce excess oil, calm redness, improve uneven texture, and fade lingering post acne marks. Clinical testing from the brand also showed improvements in skin turnover, sebum reduction, hydration, and visible skin tone while remaining suitable for acne prone and sensitive skin. 

One aspect that stands out is how comfortable the formula feels. Instead of leaving the skin dry or irritated, it maintains hydration throughout the application.

For people who have previously struggled with stronger exfoliating acids, this gentler approach is likely to be appreciated.

Who Should Use This Ampoule?

This serum is particularly suitable for people experiencing:

• Acne prone skin
• Excess oil production
• Persistent redness
• Post acne pigmentation
• Uneven skin texture
• Sensitive skin beginning azelaic acid
• It also works well for combination skin because of its lightweight consistency.

Those with very dry skin may benefit from pairing it with a richer moisturiser afterwards.

How to Use It

After cleansing and applying toner, use two to three drops across the face before moisturiser.

If you are new to azelaic acid, begin by applying a small amount every second or third evening. Once your skin becomes comfortable, you can gradually increase frequency. Daily sunscreen is recommended when using any active skincare ingredient.

• Contains an effective 10% azelaic acid concentration
• Helps reduce redness and post acne marks
• Supports the skin barrier with centella, panthenol, and allantoin
• Suitable for acne prone and sensitive skin

Cons

• Results require consistent use over several weeks

Is It Worth Buying?

For anyone interested in introducing azelaic acid without sacrificing skin comfort, this ampoule is one of the strongest options currently available.

The combination of treatment ingredients and barrier supporting ingredients creates a balanced formula that feels thoughtfully designed rather than overly aggressive. Instead of focusing only on acne, it addresses multiple concerns including redness, hydration, uneven tone, and skin texture.

It is particularly well suited for people looking to simplify their routine by choosing one multitasking serum instead of several separate treatments.

The Editor’s Thoughts Moving Forward

Many treatment serums promise dramatic results but overlook one important principle. Healthy skin responds best when it feels supported rather than constantly challenged.

SKIN1004 Madagascar Centella Azelaic Acid 10 Ampoule reflects this philosophy well. It combines the proven benefits of azelaic acid with ingredients that actively protect and calm the skin, making it easier to stay consistent over the long term.

Moving forward, this is the type of skincare formulation worth paying attention to. It recognises that effective treatment and barrier care should work together, not compete with each other. For those wanting clearer, calmer, and healthier looking skin, this ampoule earns a place among the more thoughtfully formulated azelaic acid products currently available.
