Let's be real, we all want healthy, glowing, and spotless skin, and there is no dearth of advice on the same. However, sometimes, these advices get a bit overwhelming. Face serums, hydrating creams, acids, and whatnot—there is always a constant nudge to "invest in" certain products and practices. On the other hand, there is little information available on practices that shouldn't be followed. Cosmetic Surgeon Dr Geeta Grewal lists 5 red flags when it comes to skincare, which can lead to irritation, dryness, and even premature ageing if not attended to. Red Flag #1: The Sunscreen SkipWe know, we know. Applying sunscreen every day can feel like a chore. But trust us, it's a non-negotiable for healthy skin. Think of it as your skin's best friend, protecting it from those harmful UV rays that cause wrinkles, sunspots, and even skin cancer.The American Academy of Dermatology recommends using a broad-spectrum sunscreen with an SPF of 30 or higher every single day, rain or shine. And don't forget to reapply every two hours, especially after swimming or sweating.Red Flag #2: Exfoliation OverloadExfoliating is like a deep clean for your skin, helping to remove dead cells and reveal that fresh, glowing layer underneath. But going overboard can be a major skin saboteur. Scrubbing too hard can irritate your skin, leading to dryness, redness, and even tiny micro-tears.Instead of harsh physical scrubs, consider gentler chemical exfoliants like AHAs (alpha-hydroxy acids) or BHAs (beta-hydroxy acids). These work their magic by gently dissolving dead skin cells, promoting cell turnover without all the friction.Red Flag #3: The Wrong Products for Your SkinUsing the wrong products for your skin type is like wearing the wrong shoes – uncomfortable and potentially damaging. If you have oily skin, slathering on heavy creams can clog your pores and lead to breakouts. On the other hand, if you have dry skin, using harsh, stripping cleansers can leave your skin feeling tight and irritated.The key is to know your skin and choose products that are specifically designed for your unique needs. If you're unsure, don't hesitate to consult with a dermatologist or esthetician for personalized advice.Red Flag #4: Makeup Removal MishapsLeaving makeup on overnight is a major skincare sin. Think of it as letting your skin suffocate under a layer of dirt, oil, and bacteria. This can lead to clogged pores, breakouts, and even premature ageing.Make sure to remove your makeup thoroughly every night using a gentle cleanser or makeup remover. Double cleanse if you're wearing heavy makeup, and follow up with a toner to balance your skin.Red Flag #5: DehydrationDrinking enough water is crucial for overall health, and that includes your skin! When you're dehydrated, your skin can look dull, dry, and prone to wrinkles. Plus, dehydration can actually increase oil production, which can lead to breakouts.Aim for at least eight glasses of water a day, and don't forget to include hydrating foods like fruits and vegetables in your diet.
