Note: If you think your daughter has dark complexion and she hasn't passed puberty yet, don't worry. Girls change dramatically as they grow up. Generally after age 18, her skin will gradually become fairer, and it tends to get even lighter in old age.

Why is this? You can't artificially change genetic traits. If she's genetically predisposed to darker skin, you should let nature take its course. Don't use whitening injections or bleaching agents to lighten her skin.

Under normal circumstances, during adolescence, skin that is dark may lighten slightly after the age of 18. As estrogen and progesterone secretion becomes more active, the skin tends to become fairer.

But actually, having darker skin has its benefits—its sun protection function is stronger. People with darker skin are less prone to sunburn but more susceptible to tanning. Therefore, women with darker skin should pay attention to the PA value when choosing sunscreen—it must have a PA rating, which helps prevent tanning.
