Why does niacinamide make your skin darker the more you use it?

Niacinamide can really be considered an internet-famous skin care ingredient. Before the overwhelming online promotion of Olay's Little White Bottle, not many people knew about this ingredient. The most widely known effect of niacinamide is whitening, but some people say that the more niacinamide is used, the darker the skin becomes. What’s going on?

Why does niacinamide make your skin darker the more you use it?

If you don't do a good job of sun protection, even if you use niacinamide, your skin color will still become darker based on your previous skin color. No matter what whitening skin care product you use, the speed of whitening is slower than the speed of getting tanned, so if you want to become white, you must use sunscreen.

Niacinamide is a super whitening ingredient. After using niacinamide, your skin can become whiter within about 28 days of skin metabolism cycle. It can promote facial metabolism, reduce the deposition of melanin, and quickly whiten your skin.

Whether you use niacinamide or not, you need to use sunscreen. Even if you don’t use any skin care or whitening products, if you use sunscreen every day, your skin will become whiter after a period of time.

Will my skin become darker if I stop using niacinamide?

After you stop using niacinamide, your skin will not get darker if you protect yourself from the sun. However, if you don’t, your skin will likely oxidize and turn darker after a long time, so daily sun protection and maintenance are very important.

Everyone's skin condition is different. Some people get dark easily, so they should pay more attention to sun protection. Some people are not easily tanned. After using niacinamide to whiten their skin, once they stop using it and do not do a good job of sun protection, they will get dark again in a very short time.

Niacinamide also has an antioxidant effect. Some people's skin is not dark but very yellow. Niacinamide also has a good effect in removing yellowness, but after stopping use, your skin will return to its previous state after a period of time.
