In short
To fade post-acne dark marks and sun pigmentation in Bangladesh, combine Niacinamide (5–10%) or Tranexamic Acid in the morning with daily broad-spectrum sunscreen, and use Alpha Arbutin or a gentle AHA exfoliant 2–3 nights a week. Sunscreen is essential; without SPF, UV radiation darkens melanin faster than any active can lighten it.

Post-inflammatory hyperpigmentation (PIH) and sun-induced melasma are the two most common skin complaints in Bangladesh. Because South Asian skin produces melanin readily in response to inflammation and heat, aggressive bleaching creams with harmful hydroquinone or steroids can permanently damage the skin. The safe, scientifically proven approach targets melanin production gently over 8–12 weeks.

The Cardinal Rule: No Sunscreen = No Progress
Melanin production is a natural biological response to UV radiation. Even five minutes of sun exposure without sunscreen can trigger melanocytes to deposit new pigment, reversing weeks of serum treatment. Wear SPF 50 every single morning, indoors and outdoors.
