चेहरे पर बर्फ का टुकड़ा रगड़ना

Using an ice cube on your face can indeed help reduce puffiness and redness temporarily due to its vasoconstrictive effects — it constricts the blood vessels, which can lessen swelling and calm inflammation, though these effects are usually short-lived. However, applying ice directly to your skin for extended periods can cause numbness or even damage due to cold exposure. It’s best to wrap the ice cube in a soft cloth before using it on your skin to prevent frostbite and irritation. As for the duration, a couple of minutes should suffice, and it’s wise to move around regularly—not focusing on a single spot for too long to avoid overexposure. Doing this once, maybe twice a day, should be safe, but stop if your skin becomes irritated. While rubbing an ice cube can be soothing and help improve circulation, its effects on acne are limited. It might reduce inflammation a bit, but it won’t address underlying causes of acne such as bacterial infections, excess oil production, or clogged pores. Also, the temporary oiliness you’ve noticed could be your skin’s response to the cold; it might produce more oil to cope with this new environmental change. If you have acne, it’s more effective to include a skincare routine with appropriate cleansing, using non-comedogenic products, and maybe incorporating salicylic acid or benzoyl peroxide to target acne directly. If a particular spot is very persistent, it might be wise to consult a dermatologist, as they can offer treatments like topical retinoids or antibiotics if necessary. Different skin types react differently to ice application, so if you notice any discomfort or worsening condition, stop immediately and reassess your routine. Your friend’s concern about suitability for all skin types is valid—it’s always essential to listen to your skin and adjust your regimen accordingly.
