Here is Denica. I can't see anything healthy about that difference, even if it likely partially done in photoshop and lighting. This is what is being advertising it to young women and just another push of White women as a universal standard of feminine beauty that is globally damaging and maiming. If you look at any skin bleaching advertising, it's all equated with being pretty, clean, or - for the Unilever product - "fair and lovely".
No bleaching product is safe. There is no all over concealer or lightening equivalent to fake tan. These are dangerous. Look up videos on it and you can see documentaries on what many are calling an epidemic of the problems these products do, particularly to the young women Denica's products are aimed at.
I had my hair bleached blonde throughout my chilhood to help me pass as White along with being kept inside once I reached a certain age. My mother sent me a photo album of all my childhood pictures and it's heartwrenching because while there are no photos of the hours in the chair or the talks about 'protecting my complexion', you can see all my parent's effort to portray this perfect image step-by-step until they had perfected it in my middle school years. It was never discussed in terms of race, it was always "but you look so good blonde" and how much nicer people will be if I didn't get too dark. I remember my father rebelling against that when I was in high school and started going tanning to bring out his skin colour better after years of using creams. The amount of internalized hate that I am still digging out of is enormous, let alone the damage to my scalp, hair, skin, and the potential connection to that and my other health ailments (none of the products are meant to go on kids, but they're often used on them).
And this is with a White mother who didn't know my light skinned father's racial heritage (because his family will never talk about it because they pass as White to protect themselves in a very racist part of the US much like many others, I still only have fragments at 28) - she just doesn't like how I looked dark and genuinely thought I needed and looked better lighter like the rest of the family - she still tells me how nice I would look if I went blonde again, and I wear headcaps now. My sister still bleaches her hair and tells everyone how amazing her "tan" is because to her being anything other than White would mean she would have to face all the bullshit that I've gone through and she's happier and has all the support in all the Euro-fragments and none in anything else.
It's a lot more complicated that what one singer does to her skin, there is a whole system that takes the promotion and representation of this standard of beauty and tells the rest of us that they were rather we maimed ourselves and people maimed/allow their children to be maimed than represented us as we are. When Lupita Nyong'o talked about a young woman choosing not bleach her skin because of her, there is a lot going on there, most of which is a victory for the health and well being of all of us if we could all be represented and seen as beautiful for who we are rather than "pretty...for a dark girl" that seems to be the best some representation can get.
