  intro: "Sun spots fade slowly or not at all. Honest framing first: managing them is a multi-month project, and the only real prevention is the SPF you wear today. The spots that are already there — the flat, tan-to-brown patches driven by cumulative UV exposure — respond to a combination of ingredients that slow melanin production (tranexamic acid, azelaic acid, niacinamide) and gentle exfoliation that speeds surface turnover. The results are real but incremental. Without consistent, daily SPF, any progress stalls. With it, the brightening pair can make a visible difference in three to six months. Below is the full library — what sun spots are, which approaches work, and what the realistic outcome looks like.",
