My face is getting darker n I've tried all products in d market. I was thinking it was due to FIJK flusher I was taking. I've even mixed serum to my body cream,tried bleaching creams but to no avail. I feel I'm beginning to loose my coolness. I don't really have a wonder shape but a perfect face anyone can ever think of. Now I'm freaking out I'm losing it

Several factors contribute to this,
For instance: sun. Yes,too much exposure to the sun for a prolonged period of time may darken your skin.

Genetics. If you are black (negroid), sooner or later,you will look like most of us.think of obama.groing up he was so light skinned.but eventually his African heritage had to show.
Just saying that the darkening of your face is bound to happen.

If i was you, i would stay away from any bleaching lotion/cream.those products are very bad.they create more pigmentation problems in the long run.

Just accept your natural beauty. Think of Genevieve nnaji,she is ebonic dark,but wow is she beautiful.
Equating light skin with beauty is not the healthiest philosophy. Just love your skin,whether fair,brown,red,yellow or black.

I worry becos it makes me appear dull.

use a face lotion that contains SPF, Ambi comes to mind, but there are lots more. you also have to consider if your skin is normal, oily or dry before choosing. also try as much as you can to stay out of the sun,at least unnecessary. you can use fade cream at night after washing your face. you should notice a difference in a few weeks unless there is some medication that is causing it.
