How long will Tianqidan come back to work in vain?

Tianqidan will be dark for a while and come back for nothing.

It is normal to turn black after using Tianqidan. When it turns black, you don't need to worry too much, and it will recover after a while. Because some whitening ingredients contained in Tianqidan may make some people black. At this time, you can still continue to use Tianqidan, and after a period of time, your skin will return to normal color, thus achieving whitening effect.

Tianqidan's skin care products belong to a relatively high-end grade in Korean skin care products. Tianqidan is also one of the post-series skin care products, and it is also the highest-end one.
