ROUND LAB Azelaic Acid 12 Soothing Serum — 12% Azelaic for Redness & Blemishes, Hydrating with Hyaluronic Acid

ROUND LAB Azelaic Acid 12 Soothing Serum is a lightweight, hydrating treatment formulated with 12% azelaic acid to help calm redness, reduce the appearance of blemishes, and even skin tone while supporting sensitive skin.

Made in Korea and designed to layer easily into a daily routine, this serum pairs a high-strength azelaic acid with Round Lab’s patented beta-glucan complex and ten types of hyaluronic acid. The result is a focused blemish and discoloration treatment that aims to be effective without overly drying or irritating the skin. Use gradually and follow daytime application with sunscreen.

How quickly will I see improvement in breakouts and dark spots?

Individual results vary, but most users notice reduced inflammation and fewer new breakouts within a few weeks of consistent use. Pigmentation and texture improvements typically take longer and become more evident after several weeks to months of regular application.

• 12% azelaic acid targets acne-causing bacteria and uneven pigmentation.
• Patented beta-glucan helps soothe and reduce visible redness.
• Ten hyaluronic acid variants support hydration to prevent dryness.

Can sensitive skin tolerate a 12% azelaic acid serum?

The formula is designed to balance potency with comfort: the beta-glucan complex and multiple hyaluronic acids cushion the active ingredient to reduce irritation. Start slowly to assess tolerance, using small amounts and increasing frequency only as your skin adapts.

• Begin with 1–2 drops once or twice weekly, then increase gradually.
• Patch-test on a small area before widespread use.
• Discontinue if severe irritation occurs and consult a professional.

How should I layer this serum in my skincare routine?

Apply this serum after cleansing and toning, before heavier moisturizers and oils. Because azelaic acid can leave a slight white cast if over-applied, use a pea-sized amount or the recommended drops and follow with a moisturizer to improve absorption and finish.

• Cleanse, tone, then 1–5 drops of the azelaic serum depending on tolerance.
• Seal with moisturizer; wear SPF every morning after daytime use.
• Avoid combining immediately with strong exfoliants until tolerance builds.

What texture and finish should I expect?

The serum is light, fast-absorbing, and non-greasy, designed for easy layering under other products. It hydrates without heaviness thanks to ten types of hyaluronic acid, leaving a comfortable, slightly matte finish suitable for oily and combination skin.

• Thin, serum-like consistency that absorbs quickly.
• Hydrating yet non-oily thanks to multi-weight hyaluronic acids.
• May show a faint white residue if applied too thickly; use a small amount.
