The principle of whitening cosmetics

Contrary to what people generally think, whitening cosmetics do not work by breaking down existing melanin to whiten the skin. It is unfortunate that many people misunderstand this and seek out cosmetics that unconditionally whiten the skin, often referred to as "miracle creams."

To choose a safe whitening product, first check if the company has a brand and is well-established. Famous brands are more likely to be safe because they are known to so many people. Furthermore, I believe that the older a company is, the more likely it is that it has improved its technology year after year based on reinvestment and feedback.

Furthermore, if reviews are overwhelmingly positive, it is better to wait and observe the market trends before purchasing. This is because products often contain ingredients that, while effective, can cause side effects. Above all, use approved products. Recently, as the distinction between cosmetics and pharmaceuticals has become blurred, "functional cosmetics"—which possess characteristics of both cosmetics and medicines—are on the rise.

Functional cosmetics are broadly categorized into whitening, anti-wrinkle, and UV protection products. Be sure to check for this, as products can be recognized for their functionality if they contain ingredients certified for efficacy by the Korea Food and Drug Administration or if their efficacy evaluations have been verified.
