Post Inflammatory Hyperpigmentation

The study aims to evaluate the efficacy of a facial sunscreen under two experimental conditions-untinted and tinted-in improving facial spots (melasma and solar lentigines/post-inflammatory hyperpigmentation) after 8 weeks of product use under normal conditions by adult participants.

The goal of this clinical trial is to evaluate whether the use of dermocosmetics containing Bioceramides and Niacinamide can improve post-inflammatory hyperpigmentation and promote positive impacts on self-esteem and quality of life in Brazilian Black women with facial hyperpigmentation (Fitzpatrick skin types IV to VI). The main questions it aims to answer are: * Does the treatment improve hyperpigmentation severity as measured by HASI and IGA scores? * Does the treatment improve participants' self-esteem and quality of life as assessed by MELASQoL and DLQI questionnaires? Participants will: * Use a standardized skincare routine including cleanser (0.2% Bioceramides), moisturizer (2% Niacinamide + 1% Bioceramides), serum (5% Niacinamide + 3% Bioceramides), and SPF 30 sunscreen for 12 weeks. * Attend study visits at baseline, week 6, and week 12. * Undergo standardized facial photography and clinical assessments by specialists at baseline, week 6, and week 12. * Complete questionnaires related to self-esteem and quality of life at baseline, week 6, and week 12.
