Detailed answer

Yes, hyperpigmentation can occur more frequently in individuals who have sensitivities to certain allergens or substances. Allergens or irritants can trigger an inflammatory response in the skin, leading to the production of excess melanin and subsequent hyperpigmentation. Common allergens that may contribute to hyperpigmentation include fragrances, preservatives, and certain dyes. Additionally, some individuals may develop post-inflammatory hyperpigmentation after an allergic reaction or irritation. It is important to identify and avoid potential triggers to minimize the risk of hyperpigmentation in individuals with sensitivities.
