In a recent Instagram post, Dr. Surbhi Balani, a dermatologist and cosmetologist based in Ahmedabad, India, outlined eight common skincare mistakes that can negatively impact skin health. She emphasizes that sunscreen is essential, as UV rays can cause premature aging and skin cancer, even on cloudy days. Dr. Balani warns against using harsh DIY remedies, such as lemon or toothpaste, which can damage the skin. She also advises against relying on unverified viral skincare hacks for serious skin conditions, as these often lack scientific backing. Furthermore, she highlights the importance of applying skincare products beyond the face, particularly to the neck, chest, and hands, which can show signs of aging more quickly. Over-cleansing and using harsh soaps can harm the skin barrier, leading to dryness and breakouts, so gentle cleansing is key. Dr. Balani also cautions against applying active ingredients on damp skin, which can increase irritation, and recommends patting the face dry instead of rubbing it with a towel to minimize inflammation. Lastly, she advises gradually introducing strong skincare actives to build tolerance and avoid irritation.
