Applying a few drops of castor oil under the arms before bedtime has become a trending beauty hack on social media, claimed to reduce dark spots, eliminate odor, and soften the skin. According to TV9 Bangla, while many netizens praise this practice for its skin benefits, medical experts caution about its potential risks and proper usage.
Castor oil is rich in fatty acids, particularly ricinoleic acid, and vitamin E, making it a heavy moisturizer. The underarm skin is very sensitive, and castor oil can help alleviate dryness, deeply hydrate, and soften this delicate area. Its antioxidant and anti-inflammatory properties may help remove dead skin cells and reduce dark patches gradually, as well as soothe irritation caused by shaving or waxing.
However, castor oil is thick and comedogenic, meaning it can clog pores. Since the underarms have many sweat glands, leaving castor oil on overnight might lead to clogged follicles, causing acne, rashes, or folliculitis. People with sensitive skin might also experience allergic reactions such as itching or redness.
Contrary to popular belief, castor oil does not directly eliminate underarm odor because odor is caused by bacteria, and the oil lacks antibacterial or deodorant properties. Experts recommend precautions if one chooses to use castor oil on underarms: test a small amount on the inner elbow for 24 hours to check for allergies, dilute the thick oil with a few drops of coconut or almond oil, and rather than leaving it overnight, massage it gently 20-30 minutes before showering and then wash it off.
Why this matters
Underarm care is essential not only for aesthetic reasons but also for hygiene and skin health. Popular beauty trends can offer benefits but may also pose risks if not used properly. Understanding the science behind such remedies helps consumers make informed decisions and avoid skin problems.
In summary, while castor oil underarm application can moisturize and potentially lighten dark patches, it should be used cautiously and not as a substitute for deodorants or antibacterial products. Proper patch testing and moderation are key to reaping benefits while minimizing side effects.
