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, 12% azelaic acid treatment designed to calm redness, address blemishes, and even skin tone while delivering hydrating support.

This Korean-formulated serum combines a high concentration of azelaic acid with a patented beta-glucan complex and ten varieties of hyaluronic acid to balance effectiveness and tolerance. It targets the appearance of active breakouts, dark spots, and uneven texture while keeping skin comfortable and hydrated. The texture absorbs quickly, layers well under moisturizer and sunscreen, and is intended to be introduced gradually into routines to minimize irritation.

How quickly will I notice changes in breakouts and dark spots?

Visible improvements depend on your skin and consistency. Many users observe reduced redness and fewer active lesions within a few weeks, while hyperpigmentation and texture changes commonly require several weeks to months of regular use.

• Start with 1–2 drops once or twice weekly, increasing slowly.
• Consistent nightly or daily use usually shows clearer skin over time.
• Combine with sunscreen to protect fading spots during daytime.

Is this safe for sensitive or reactive skin?

ROUND LAB pairs 12% azelaic acid with a patented beta-glucan complex to help soothe sensitivity and support the skin barrier. Introduce the serum gradually and monitor for stinging or irritation; the formula aims to be effective while reducing harshness.

• Use small amounts at first to assess tolerance.
• Beta-glucan helps calm visible redness and discomfort.
• Avoid mixing with strong exfoliants or retinoids without guidance.

How should I layer this serum within my skincare routine?

Apply the serum after cleansing and toning, before heavier creams and oils. Because it contains high azelaic acid, a pea-sized amount or 1–2 drops is usually enough; follow with moisturizer and broad-spectrum sunscreen during the day.

• Cleanse and tone, then apply 1–5 drops of the serum depending on tolerance.
• Follow with hydrating moisturizer to minimize potential white cast.
• Use sunscreen daily to protect treated areas and support pigment improvement.

Will the serum leave a white residue or alter makeup?

At higher amounts the concentrated formula can leave a faint white cast, so use sparingly and blend well. Layering a moisturizer or allowing full absorption typically prevents visible residue and ensures a smooth base for makeup.

• Apply a pea-sized amount for face coverage to avoid white cast.
• Allow a moment to absorb before applying moisturizer or makeup.
• Reduce product quantity if you notice any visible film on skin.

Who this is for: ROUND LAB Azelaic Acid 12 Soothing Serum is suited for people dealing with frequent breakouts, uneven tone, or post-acne discoloration who want a potent yet considerate approach. It’s a fit for oily to combination skin types and those with sensitive or reactive skin seeking targeted blemish care, provided they introduce the product gradually and use sunscreen during daytime routines.
