11 Skincare Ingredients to Avoid in Indian Weather

5. Synthetic fragrance (Parfum)

Many lotions, sunscreens, and cleansers contain synthetic fragrance to mask base scents. In hot weather, sweat and heat accelerate the chemical breakdown of these fragrances, raising the chance of irritation and allergic contact dermatitis. Fragrance breakdown products can sting sensitive skin and may cause redness or itchy rashes—especially when combined with pollution particles during outdoor commutes. For anyone with sensitive skin or a history of reactions, fragrance-free products are safer during humid seasons and travel to high-heat areas. Even if you tolerate fragrance at home, try fragrance-free sunscreen and face cream when you expect long outdoor exposure. For a gentle alternative, look for products labelled “fragrance-free” or with very low essential-oil content; these reduce the risk of heat-induced irritation while keeping your routine simple and effective.
