Radiant" and "brightening" are both meaningless words. Skin can't be radiant -it has no inner light source or source of radioactive isotopes, or any bio-luminescence. Skin does not emit light so therefore "radiant" means nothing and skin can not be more of something it never was at the start.
Brightening is similar. You can brighten your home lighting by switching all your light-bulbs from 40 watts to 60 watts or opening curtains and letting in more light. Again, skin does not emit light so you can't brighten it.
You cna shine a brighter light on your skin and it will look brighter in the same way a room looks brighter under brighter light. Radiant, glowing and brightening are all weasel words that are purely advertising and being used to make you think something is wrong and that a creme or lotion will fix it. Really -you skin isn't radiant or glowing because it's not supposed to glow or radiate light.
If it did you would be radioactive and have a whole bunch of other problems -such as leukemia from radiation poisoning. Radium will make you glow -but it will also kill you! Lightening is the act of changing the color value from dark to light.
Bleaching is removing pigments form something so it is less pigmented and both can be applied to skin. Whether these to things should be used for skin is another story. Bleaching is very harsh and damaging to clothes, hair and skin.
You can't bleach anything without doing some damage. And skin bleaches -since they are so irritating can make the skin turn thicker for protection and make the skin cells produce even more color pigments -again as a protection. So while one or two might make you look lighter for a while -too many will make your skin thick, scarred and dark.
Lighteners are for targeted spot treatments -lighteners are to fix spots with sun damage pigmentation or acne scarring. This isn't for changing race or ethnicity -this is to fix a few particular spots. Some work slightly, others do nothing.
Dermatologists have treatments that work far better than a creme from the drug store -but these have side effects and some can't be used under certain circumstances. You can't change your race or ethnicity through cosmetics or bleaching. Skin pigments are produced according to the messages the cells receive from your genes and no bleach, lotion, oil and cream will ever change the message sent by your genes.
All you are doing with lighteners and bleaches is burning your skin and damaging your skin in the long term. Skin color changing cosmetics is racism at its worst -light skin is in no way superior. And your skin tone is not anything that is under anyone's control: you have the skin color your genes tell you to have and it does not make you or anyone lesser or better than any other color.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
