Does Onion Remove Scars?
No, onion doesn't remove scars, but onion extract shows promise in reducing the appearance of scars. While it won't erase scars completely, studies suggest it can improve their texture and color.
Onion extract, particularly containing quercetin (a powerful antioxidant), possesses anti-inflammatory and healing properties. This makes it a popular ingredient in topical scar treatments. Many studies, as cited below, have explored its effectiveness in reducing the appearance of various scars including hypertrophic and keloid scars. These studies have indicated varied success with some showing statistically insignificant improvement in scar height, but positive effects on other aspects of scar appearance. The mechanism of action involves a combination of anti-inflammatory and wound-healing properties.
- Improved Appearance: Several studies indicate that onion extract can improve the overall appearance of scars, reducing redness and potentially improving texture. However, the degree of improvement varies depending on the scar type and individual response.
- Not a Cure-All: It's crucial to understand that onion extract is not a miracle cure. It won't completely eliminate scars, but it may lessen their visibility.
- Topical Application: Onion extract is typically used topically, often in gels or creams, combined sometimes with other beneficial ingredients like aloe vera.
Supporting Evidence:
- Studies: Research (like those found in PubMed and other reputable medical journals) shows that onion extract gels have been used for over 60 years in scar treatment. While results vary, improvements in scar appearance have been reported. However, some studies note its statistical ineffectiveness in improving scar height.
- Mechanism: The beneficial effects are attributed to the presence of quercetin, an antioxidant known for its anti-inflammatory and wound-healing properties.
- Commercial Products: The presence of onion extract in commercially available scar gels further highlights its use in scar management.
It's important to note that individual results may vary, and consulting a dermatologist is recommended before using any topical scar treatment, including those containing onion extract.
