In daily life, we often use various personal care products, but are these truly necessities? Not necessarily!
Expensive moisturizers. Dr. Rebecca Kazzin of Johns Hopkins University states that no studies prove more expensive moisturizers are inherently superior. She recommends standard moisturizers containing retinol or antioxidants with SPF 30+ for effective anti-wrinkle and skin care.
Cold prevention medications. Dr. Milos notes that studies on vitamin C's effectiveness against colds have yet to reach definitive conclusions. Mayo Clinic research indicates certain nasal sprays may impair the sense of smell. Experts emphasize that thorough, frequent handwashing remains the key to preventing colds.
Vaginal douches. The American College of Obstetricians and Gynecologists (ACOG) states that the vagina has a self-cleaning mechanism. Vaginal douching is not only unnecessary but can disrupt the vaginal pH balance, increasing the risk of infection. Experts advise seeking a gynecological examination promptly if abnormal discharge or odor occurs.
Mouthwash. Except for those with oral conditions like xerostomia, healthy individuals need not use deodorizing mouthwash. Experts advise brushing twice daily and flossing to prevent bad breath. Persistent halitosis may signal gingivitis, cavities, or even diabetes.
Facial toners.Dr. Patricia Farris, Professor of Dermatology at Tulane University School of Medicine, states that most people can restore skin pH without toners. She recommends using neutral cleansers or unscented regular soap to remove skin oils. Vitamin supplements. Dr. Milros asserts that healthy individuals need no extra vitamins, and indiscriminate supplementation is harmful rather than beneficial. Experts advise balanced diets rich in fruits and vegetables.
