Detailed answer

Certain chemicals or ingredients, such as fragrances, preservatives like parabens, and certain exfoliating agents like glycolic acid, can potentially trigger hyperpigmentation in individuals who are sensitive to them. This is because the skin's reaction to these substances can lead to inflammation and increased melanin production, resulting in pigmentation irregularities. It is essential for individuals with sensitive skin or a history of hyperpigmentation to be cautious and avoid using products that contain these potential triggers. Consulting with a dermatologist or skincare professional can help identify specific substances to avoid and recommend suitable alternatives.
