Azelaic Acid

Pros

• Effective at reducing redness and managing rosacea symptoms
• Helps control and prevent cystic and fungal acne
• Fades post-acne red marks and hyperpigmentation
• Improves overall skin texture and pore appearance
• Pairs well with other actives like tretinoin or adapalene for many users

Cons

• Commonly causes an itching or stinging sensation during application
• Can lead to skin purging in the initial weeks
• High concentrations (15%+) can be too harsh for sensitive skin
• Risk of skin barrier damage if used twice daily immediately without acclimation
• May show no results for some users even after long-term use

Caveats

• One user reported the acid stripped the protective coating off their eyeglasses where the lenses touched their cheeks
• Should only be introduced once the skin barrier is healthy and hydrated
• Prescription versions (like 15% gel) are often significantly more potent and irritating than 10% OTC options

Best for

• Individuals with rosacea or persistent facial redness
• Treating cystic acne and fading red post-acne marks
• Users looking for a gentle chemical exfoliant that targets texture

Avoid if

• You currently have a compromised or dehydrated skin barrier
• You are unwilling to tolerate temporary itching or stinging sensations
• You prefer immediate results, as it often requires several weeks to months to show efficacy
