Background

Syntaxin-4, a member of the Qa sensitive factor attachment protein receptor (SNARE) syntaxin family has been implicated in fusion events at the plasma membrane in a number of cells in the immune system. This protein enables sphingomyelin phosphodiesterase activator activity, and is active in glutamatergic synapse and postsynapse. Study demonstrates that syntaxin-4 plays a critical role in the secretion of IgE from plasma cells and sheds some light on the mechanisms by which these cells constitutively traffic vesicles to the surface for secretion. Together with STXB3 and VAMP2, it may also play a role in docking/fusion of intracellular GLUT4-containing vesicles with the cell surface in adipocytes and in docking of synaptic vesicles at presynaptic active zones (By similarity).

Just an OKAY Moisturizer, That's it.
I think this is a good moisturizer, as far as anything else it claims such as an even skin tone, I wouldn’t agree. I used the bottle and didn’t notice any changes in my skin and blemish appearance. It’s not too thick and it’s not greasy. I will say I had a successful run with brightening my inner thighs. I added this to the mix, and for some reason, I began chafing leaving Little bumps in my inner thighs that turned into 50-60 dark spots 😭 I’ve never had a problem with chafing or dark spots from bumps in my inner thighs before. I’m not sure if it because I was using it in conjunction with something else it caused issues. I would recommend it as a lotion, but that’s it.

Must Have Beauty Product
This one of my favorite and must have beauty products. Works so quickly for chapped lips and just keeping my lips soft every day. The formula isn’t sticky at all and you can really feel how hydrating and nourishing it is

Amazing product but star down on price
I desperately needed a healing lip balm for my perpetually chapped and scarred lips, and at first was skeptical that this was nothing but a glorified aquaphor, which works well enough for me but I was curious about better treatments. After some weeks of regular use, my lips feel incredible. I am sold. I only wish two things: that it was a smidgen cheaper, and that there was a version with SPF so I could have one to wear out during the day and have it’s magic working all the time.
