11 Sensitive Skin Care Dos and Don'ts for India

4. Patch Test New Products — Do a 48–72 hour patch test; Don’t skip this step when adding actives

Do: Test any new product on a small skin area—behind the ear or on the inner forearm—then observe for 48–72 hours for redness, itching, or delayed rashes. This is the simplest way to spot sensitivities before they become full-face reactions. Keep a short log: product name, date applied, and any signs observed. This habit is especially helpful in India where seasonal allergies and pollution can make the skin more reactive, and where packaging or ingredient listings may vary between brands.
