I'm all for questioning the chemicals we put into and on our bodies, but there's some serious misinformation and ignorant answers here causing all sorts of unnecessary alarm. Before everyone accuses Tarte of trying to give them cancer, step back and take a breath. The Wikipedia referenced by one of the other Sephora members contains only ONE citation to a scientific article and that article says nothing about Lysophosphatidic Acid being a carcinogen.
From looking at research papers I can access without paying for PubMed and (the like), here's my conclusion: Lysophosphatidic Acid is found in animal cells and greatly helps in healing of said cells and the prevention of cell death. But since it causes your cells to heal itself, if the cell is already cancerous, it can help the cancer spread. Lysophosphatidic Acid doesn't give you cancer like asbestos. It's not a mutagen; it's a mitogen. It doesn't change the DNA within your cells, it just encourages cell growth and proliferation. This is both a good thing and bad thing since the more your cells divide, the higher the chances of there being an error. However, exfoliation of skin cells also increases cell turn over. So... scrubbing your face gives you cancer? Think about that for a minute.
On top of that, I see no research on whether Lysophosphatidic Acid can be absorbed through human skin via cosmetics. Whatever the case, it's already in your body, doing things like helping it to heal from wounds and increasing fluid absorption in your intestines.

There is no evidence that lysophosphatidic acid could be absorbed through the skin. I am sure as is a friend of mine who has done copious amounts of cancer research, that it would be safe. However as you note, an alternative could be considered.

Again, a question better suited for tartes customer service team on tartes website. I would think that a carcinogenic ingredient would require a warning label on a product. Considering there is none, probably not the case. I will add, do you know how many ingredients are carcinogens or possible carcinogens? Everything in moderation!
remember - natural doesn't necessarily mean safe: lead and mercury are natural, too, but not safe. and I think that if any of the ingredients actually changed the structure of your skin, the FDA wouldn't allow it in OTC cosmetics. so I really wouldn't worry about the toxicity of any of the ingredients.

Yes, I use to for touch ups and it works very well. Much better than reapplying foundation or powder. I actually have found, though, that since using it, I don't need to touch up that much! It does such a good job with keeping that matte look.

LPA (Lysophosphatidic Acid) exists in human skin and is an essential element in the cell membrane due to its ability to promote healthy epidermis development. Formulation with the ingredient results in a balanced skin barrier and better cell differentiation as well as pore size reduction.

LPA is pretty much a known carcinogen. it is a "signaling" molecule that has been linked to cancer.
"Dysregulation of autotaxin or the LPA receptors can lead to hyperproliferation, which may contribute to oncogenesis and metastasis."
i was disappointed to find this out after assuming that tarte was a wholesome "natural" cosmetics company. i also discovered that this product made me itch because of the LPA in it.
makeup is supposed to enhance your natural beauty, not hinder or alter your body's processes.
tarte, please think about your customers safety and well-being and live up to your "natural" name - don't just be concerned with a products' performance and how exquisite it sounds.
