In Hong Kong, many people facing the troubles of acne hope to find quick and effective solutions. Recently, many netizens have inquired about using azelaic acid to treat red acne scars, only to find numerous negative reviews online. Today, we will delve into the actual efficacy of azelaic acid and clarify some common misconceptions.
First, azelaic acid is not, as some YouTubers claim, the culprit behind skin allergies or worsened red scars. In fact, azelaic acid is a widely recognized dermatological medication primarily used to treat acne and related skin issues. Its benefits can be summarized in three aspects: anti-inflammatory, reducing keratin buildup, and antibacterial effects.
The anti-inflammatory effect of azelaic acid is notably significant, as it inhibits tumor necrosis factor (TNF) and reduces inflammatory responses, thus alleviating skin redness. During acne inflammation, the body produces peroxides, which can harm normal tissue, while azelaic acid effectively cleanses these peroxides to prevent further damage.
Moreover, azelaic acid helps reduce the excessive buildup of the stratum corneum, as acne formation is often associated with keratin buildup, bacterial growth, and androgens. By controlling these factors, the occurrence of comedones will naturally decrease. With prolonged use of azelaic acid, it can positively impact acne improvement.
Regarding the red acne scars mentioned by some users, these scars typically result from excessive blood vessel proliferation related to chronic inflammation. If the underlying problem—namely, the acne itself—is not addressed, the condition of the red scars cannot improve. Using azelaic acid will not worsen red scars; rather, it is an important step in treating acne.
If you hear someone say that azelaic acid will cause red scars to reappear, this is completely a misunderstanding. Compared to other treatment medications, azelaic acid has fewer side effects; any temporary redness experienced is related to the skin’s adaptation and usually improves within one to two weeks after use. Once the skin gradually adapts, it can be continuously used to achieve optimal effects.
Azelaic acid is suitable for individuals with mild to moderate acne and can be combined with other acne medications to enhance treatment effects. However, if significant redness occurs due to severe cystic acne, considering treatments like pulse dye laser therapy is also a valid option to effectively improve redness and boost self-confidence.
It is important to emphasize that the process of eliminating red scars requires patience. It is recommended to use azelaic acid regularly according to medical advice. Consistency is key to seeing noticeable changes. Though it takes time for red acne scars to fade, ongoing treatment is definitely worthwhile.
