The cream includes UV filters, and that matters for this type of product because sunlight can make darkened areas stand out more and appear more persistent. In that sense, the UV-filter element supports the cosmetic goal of a more even-looking tone by reducing additional UV impact on the area where the cream is applied.
However, the provided product information does not specify an SPF rating, water resistance or the level of UVA/UVB protection. For that reason, it is safest not to treat it as a complete replacement for a dedicated sunscreen when the skin will be exposed to strong sun, prolonged outdoor activity, sweating or swimming.
If the treated area is usually covered by clothing, the UV filters may be a useful extra layer within your daily body-care routine. If the area is exposed, combine the cream with practical sun protection: avoid intense midday sun when possible, cover the area with clothing, and use a sunscreen product appropriate for the level of exposure. This is especially important because repeated UV exposure can make uneven pigmentation look darker even when a brightening cream is used consistently.
For best cosmetic results, think of brightening care and sun protection as working together. The cream can help target the appearance of uneven tone, while limiting UV exposure helps prevent the contrast from becoming more noticeable.
