ROUND LAB Azelaic Acid 12 Soothing Serum — 12% azelaic acid, calming beta‑glucan, lightweight hydrating texture

ROUND LAB Azelaic Acid 12 Soothing Serum is a lightweight, 12% azelaic acid facial serum designed to target acne-prone, red, and uneven-toned skin while delivering hydrating support.

This Korean-formulated serum combines a high 12% concentration of azelaic acid with Round Lab’s patented beta-glucan complex and ten types of hyaluronic acid to balance exfoliation, calm irritation, and maintain moisture. The texture absorbs quickly and layers smoothly under moisturizers and sunscreen. Because of the active concentration, application technique matters: small doses build tolerance and reduce surface residue for a seamless finish.

How does this serum help reduce visible breakouts and dark spots?

The core active, azelaic acid at 12%, works on the skin’s surface to support reduction in the appearance of active blemishes and uneven pigmentation. It supports skin turnover and helps refine texture so post-breakout marks and hyperpigmentation look less noticeable over time.

• 12% azelaic acid concentration for targeted blemish and spot care
• Formulation supports visible reduction of acne marks and uneven tone
• Fast-absorbing base that layers with other treatments

Will this serum be too harsh for sensitive or easily irritated skin?

Round Lab pairs the active ingredient with a patented beta-glucan complex aimed at calming redness and minimizing sensitivity, allowing a higher azelaic acid level to be used more comfortably. Start slowly and observe how your skin reacts to build tolerance.

• Patented beta-glucan helps soothe and support the skin barrier
• Recommended gradual introduction: 1–2 times weekly, increasing slowly
• Hydrating hyaluronic acids reduce drying sensations

How should I apply the serum to avoid residue and get the best results?

Because concentrated azelaic acid can leave a slight white cast if overapplied, use a little at first and increase as tolerated. Apply as directed in small increments, then follow with moisturizer and daytime SPF to ensure comfortable wear and protection.

• Begin with 1–2 drops; work up to 3–5 drops as tolerated
• Use only a pea-sized amount if applying across the whole face
• Follow with a moisturizer and always use sunscreen during the day

How does this fit into a routine for oily or layered skincare?

The serum’s lightweight, non-greasy finish and ten types of hyaluronic acid provide hydration without heaviness, making it compatible with oil-control routines or multi-step regimens. It layers well under water-based or cream moisturizers and won’t interfere with most actives when introduced carefully.

• Fast-absorbing texture suitable for oily and combination skin
• Hydration from multiple hyaluronic acid molecules prevents tightness
• Can be integrated with other actives after patch-testing

Who is this for: ROUND LAB Azelaic Acid 12 Soothing Serum is made for people managing frequent breakouts, visible post-acne marks, uneven skin texture, or persistent redness who want a potent yet calming topical option. It suits oily and combination skin types that need targeted blemish care without heavy creams, and it can be adopted by sensitive skin users who introduce it gradually and follow with barrier-supporting products.
