ROUND LAB Azelaic Acid 12 Soothing Serum 1.01 fl oz — 12% Azelaic, Beta-Glucan & 10 Hyaluronic Acids

ROUND LAB Azelaic Acid 12 Soothing Serum is a lightweight facial serum that combines 12% azelaic acid with patented beta-glucan and 10 kinds of hyaluronic acid to help reduce the appearance of breakouts, redness, and uneven tone while supporting hydrated, calm skin.

This serum pairs a high-strength azelaic acid concentration with hydrating and soothing actives to address blemish-prone, discolored, or irritated skin. The formula aims to visibly diminish the look of active breakouts, post-acne marks, and redness while maintaining a skin-friendly texture that layers well under moisturizers and sunscreen. Because of the potency, application guidance and gradual build-up are recommended to get results without unnecessary irritation.

How does the 12% azelaic acid help my skin?

Azelaic acid at this concentration works as a targeted topical treatment to visibly reduce the look of active acne, diffuse redness, and even out hyperpigmentation. It’s suitable for areas where breakouts and post-inflammatory dark spots are common, and it supports smoother skin texture with regular use.

• 12% azelaic acid concentration for focused topical support
• Formulated to address active breakouts and visible post-acne marks
• Helps refine uneven texture for a more uniform-looking complexion

Will this serum be too harsh for sensitive or reactive skin?

ROUND LAB pairs the azelaic acid with a patented beta-glucan complex designed to reduce the look of redness and help minimize sensitivity. Starting slowly—low frequency and small amounts—lets skin acclimate while the beta-glucan helps maintain barrier comfort.

• Patented beta-glucan to soothe and support sensitive skin
• Begin with 1–2 drops once or twice weekly, then increase gradually
• Recommended layering with a moisturizer to reduce potential irritation

How does the texture and hydration profile feel on skin?

The serum is formulated for a fast-absorbing, non-greasy finish, boosted by ten types of hyaluronic acid to deliver multi-depth hydration. This lightweight feel makes it easy to layer under other skincare or makeup without piling or heavy residue.

• Contains 10 kinds of hyaluronic acid for multi-layer hydration
• Lightweight, fast-absorbing texture suitable for oily to combination skin
• Designed to layer smoothly under moisturizer and sunscreen

Are there any application tips or visible side effects I should know about?

Because the azelaic acid level is relatively high, using too much product can leave a slight white cast. Follow the recommended dosing and always use sunscreen during daytime to protect treated skin. Gradual introduction helps you monitor tolerance and reduce the chance of irritation.

• Use a pea-sized amount or 1–2 drops to start; increase up to 5 drops as needed
• Start 1–2 times per week, then build frequency to daily if tolerated
• Apply moisturizer or sunscreen over the serum; sunscreen is essential for daytime use

Who is this for: This serum is best for people with blemish-prone or uneven-toned skin who want a targeted topical solution that pairs a high-concentration active with soothing and hydrating support. It’s particularly useful for adults dealing with persistent breakouts, lingering post-acne discoloration, or those seeking a lightweight, layered treatment within a routine. If you have extremely reactive or compromised skin, introduce it slowly and consider patch-testing or consulting a skincare professional first.
