Hi!

What I am looking for is a bit confusing...  In some products is listed as an Ingredient, but in other places I find it listed as a Product itself. I even found it as a supplement!! (?!?!?!?)

The only information that I have available is that it helps to lighten skin and apparently it works like magic!

For reference, I have this:

Skin Whitener

SKIN LIGHTENING / ANTI-AGE SPOT

(Bottom of the page)

I don't speak Portuguese, but it reads very similar to Spanish, -which I understand- and so I was able to read about 85-90% of this article:

Dermatologia Estetica: MELASMA  by Dr. Denise Steiner.
(Lot's of information and a mention of Melawhite as an agent in the treatment of Melasma)

Charmzone Cream
  (Lists Melawhite as an Ingredient)

and last, but not least, a soap with Melawhite as an ingredient again!:

Any help would be greatly apreciated!!

Thanks in advance!

Melawhite is listed as an inhibitor of melanin synthesis. This is really easy to do, because anything that looks like tyrosine will do the job. I do not think it is a good idea to keep adding more actives that have the same mode of action. We already have kojic acid, and arbutin.

Also, I do not like at all the composition: leucocyte extract? I can't believe that they are actually using cell lysates. That is so dangerous! There is the chance of introducing viruses, I would not touch anything that has been in contact with live cells.  The "fibroblast conditioned medium" of TNS scares me. This is the kind of stuff that the FDA would not allow in medicines but, because it is a "cosmetic", skin care companies can get away with it.

Go instead for glutathione, magnesium ascorbyl phosphate, etc.

Also, in Melawhite, another example of cheating by the industry. They baptize, and trade name, a very  inexpensive plant polysaccharide, Ceratonia siliqua gum, as Phytaluronate, which sounds (I wonder why?) like awfully expensive sodium hyaluronate/hyaluronic acid. 

Paula Begoun is publishing what she says is the last edition ever of her "don't go to the cosmetic counter..." She is bitter that her efforts to change the cosmetic industry have been for nothing.  I understand her feelings, but why should they change if they can get away with cheating?

Dear Hannah:

Hi!  Thank you for replying so fast!

I apreciate and value your opinion and knowledge! It is not every day that an expert answers my questions! 

I am going to sound really dumb, so please forgive me, I am new to all this and I am hoping to learn new things every day, so bear with me:

What are Cell Lysates? 

When you mention "fibroblast conditioned medium" it makes it sound as something that has to do with embryos.  (Maybe I am WAAAAAAY off!) But what is a fibroblast conditioned medium?

I am so sorry about my ignorance! I will try to read a bit more and inform myself to be up to par with everyone I promise!.

(Maybe going back to school and taking a few Biology and Chemistry classes would do me some good! Even at this age....)

I am going to be looking into Paula Begoun's books so that I can get myself aclimated with some of the terms.

Thank you again for all your help Hannah!! Your help and input is what makes this company such a wonderful place to shop from! It's personalized care that can't be found anywhere else!

Hugs:

A cell lysate is what you get when you break cells. It is really hard to break most plant, and bacterial cells because they have cell walls, but to breal animal cells all you have to do is to add water to them. Because of the lack of cell walls, animal cells will just explode and release their contents. This is why when we use eye drops or nose drops or IV, the salt concentrations is similar to that in our cells, "saline solution".

Fibroblast conditioned medium is a waste product of growing animal cells in a  Petri dish. The cells stick to the bottom of the dish (this is what normal cells will do) and every day or so you remove the old medium (now "conditioned") and add fresh medium with all the nutrients and other stuff those cells need to stay alive and reproduce. If the cells are fibroblasts, a type of cell, then you get fibroblast conditioned medium.
