The Ordinary AHA 30% + BHA 2% Peeling Solution, Advanced Exfoliating Peel for Brighter Skin
The Ordinary Azelaic Acid Suspension 10%, Formula for Uneven and Blemish-Prone Skin
Introduction
Azelaic acid is one of skincare's most versatile and underappreciated active ingredients, capable of addressing acne, rosacea, post-inflammatory hyperpigmentation, and uneven skin tone simultaneously without the irritation commonly associated with retinol or strong exfoliating acids. Naturally occurring in grains like wheat and barley, it works by inhibiting the enzyme tyrosinase to reduce melanin overproduction, killing acne-causing bacteria, and normalizing the skin cell turnover cycle. For those dealing with multiple skin concerns at once, an azelaic acid serum is one of the most efficient single-product solutions available.
Key Features/Ingredients to Look For
- Concentration Level: Prescription azelaic acid formulas contain 15% to 20%, while over-the-counter serums typically range from 5% to 10%; even lower concentrations provide meaningful brightening and redness-reducing benefits, while higher concentrations deliver faster results for stubborn hyperpigmentation and active acne.
- Formulation Base: Azelaic acid is available in gel, cream, and serum formulations; gels tend to work better for oily and acne-prone skin while cream-based formulas are better for dry or sensitive skin, and choosing the right base ensures the active ingredient is delivered comfortably for consistent daily use.
- Complementary Brightening Actives: Some azelaic acid serums include kojic acid, niacinamide, or vitamin C derivatives that work synergistically to enhance the overall brightening and tone-evening effect, making these combination formulas particularly effective for persistent hyperpigmentation and discoloration.

Final Thoughts
Azelaic acid serum is one of the safest and most effective treatments for anyone dealing with acne, redness, rosacea, or stubborn hyperpigmentation, and its excellent tolerability profile makes it suitable for use during pregnancy when many other active ingredients are restricted. Apply once or twice daily to clean skin before moisturizer, and expect gradual but consistent improvement over four to eight weeks of regular use. Pairing azelaic acid with daily SPF 30 or higher application will maximize its skin-tone-evening effects by preventing new UV-triggered discoloration from forming.
How Azelaic Acid Helps Skin
Azelaic acid is a gentle yet versatile multitasker that suits sensitive and acne-prone skin. It clears breakouts by killing acne-causing bacteria and unclogging pores, fades the post-acne dark marks and melasma that pigmentation treatments target, calms the redness of rosacea, and gently smooths texture, all with little irritation. This rare combination of anti-acne, anti-redness, and brightening benefits makes it a favourite for those juggling breakouts and pigmentation, or for rosacea-prone skin that can’t tolerate harsher actives. It’s also considered safe during pregnancy, unlike retinoids.
How to Use an Azelaic Acid Serum
Azelaic acid typically comes in 10 percent (over-the-counter) to higher prescription strengths. Apply it after cleansing, once or twice daily, and follow with moisturiser. A mild tingling on application is normal and usually settles. It layers well with most ingredients, including niacinamide and hyaluronic acid, and is gentle enough to combine with a careful routine. As always, wear daily SPF, especially since you may be treating pigmentation. Results, clearer skin, fading marks, calmer redness, build gradually over several weeks of consistent use.
