TOSOWOONG Azelaic Acid 10% Face Serum — 33 ml, Redness Soothing & Niacinamide Hydrating Treatment

Designed for sensitive and acne-prone skin, this Korean-formulated serum blends 10% azelaic acid with niacinamide, hyaluronic acid, ceramide, and Centella Asiatica to target visible redness, texture irregularities, and excess oil without heavy, pore-clogging ingredients. The formula uses a naturally derived green tint instead of synthetic colorants and comes in a 33 ml (1.11 fl. oz.) dropper bottle for easy, controlled application.

How does this serum help reduce facial redness and rosacea-prone flare-ups?

Azelaic acid at 10% works as a multi-purpose ingredient to visibly soothe and even out skin tone when used consistently. Supportive botanicals and barrier-strengthening lipids help minimize irritation and help the skin recover a calmer appearance.

• 10% azelaic acid to target visible redness and uneven tone.
• Centella Asiatica to comfort irritated skin and reduce discomfort.
• Ceramide to support and restore the skin’s moisture barrier.
• Lightweight texture suitable for layering under moisturizers and sunscreen.

Will this serum help with blemishes and oily, breakout-prone skin?

The combination of azelaic acid and niacinamide helps regulate oiliness and smooth rough texture, supporting fewer noticeable breakouts over time. It’s formulated to assist in clarifying the complexion while remaining non-comedogenic.

• Niacinamide to balance sebum production and refine skin texture.
• Azelaic acid to reduce the look of existing blemishes and prevent new ones.
• Hyaluronic acid adds hydration without heaviness.
• Recommended for gradual introduction to reduce irritation risk.

How should I introduce and use the serum in my routine?

Start slowly—especially if your skin is sensitive—then increase frequency as tolerated. Apply to clean, dry skin and follow with moisturizer and sunscreen in the morning.

• Begin with 1–2 drops nightly; build up to 4–5 drops as tolerated.
• Use after cleansing and toning, before heavier creams or oils.
• Always wear SPF during daytime use to protect treated skin.
• Perform a patch test before full-face application if you have reactive skin.

Is this serum gentle enough for sensitive skin?

Formulated and clinically tested for low irritation, the serum aims to be suitable for many sensitive skin types when introduced carefully. Users with very reactive skin should still patch-test and increase use gradually to confirm tolerance.

• Clinically tested for low irritation.
• Plant-derived natural green hue—no artificial coloring agents.
• Minimal, supportive ingredient list to reduce potential irritants.
• Patch testing recommended before regular application.

Who this is for: This serum is intended for people with redness-prone, acne-prone, or uneven skin tone who want a targeted topical option that blends azelaic acid potency with calming and hydrating support. It’s suitable for those seeking a lightweight, everyday treatment that can be layered into both morning and evening routines—provided SPF protection is used during daytime—and for anyone who prefers formulations without synthetic colorants. If you have severe or persistent rosacea or very reactive skin, consult a dermatologist before starting a concentrated active such as 10% azelaic acid.
