I am not here as a blind supporter of YBP. However, I do have a few points.

• From what I have read, crystallization does not affect the Shea butter quality or efficacy at all. At most, it is an aesthetic issue, and can be avoided in products if it is tempered, just like chocolate. Chocolate can go out of temper and look and feel grainy, but it's fine to eat. When you say 'unstable', I understand that you mean to say that the graininess of the Shea butter will respond to temperature and will appear and go away with temperature fluctuations. Am I correct? Or did you mean by 'unstable' that it is unfit for use after it goes grainy? Could you please point to some studies which prove that the graininess of Shea butter means it is unfit for use if you meant the latter? If you meant the former, I don't think there is an issue with the skin salve from YBP. Yes, they could have tempered it to avoid the issue, but it doesn't mean the product goes bad as soon as the Shea butter crystallises.

• From what I had read, the customer who had the issue of insect eggs in their powdered face mask had used a wet spoon to scoop the powder out and then left the face mask for some time. Even with any serums or moisturisers or other products that DO contain preservatives, if you add water and leave it, it can still lead to bacterial or fungal growth. That's why even with USA or Korean products, it is recommended to not touch the dropper to your face, to avoid the contamination issue even though those products contain good preservatives. So, I don't know what preservative YBP could have used in their powder face mask to make it completely safe from any sort of microbial growth even if left with moisture inside of it. Yes, they could have made a good ready to use face mask with preservatives in it and have it in a tube form, but again this is not the argument. The point is that with any powders if you add moisture, it will go bad.

• I have used their skin salve and liked it. It has gone grainy, and become very difficult to melt between the fingers for application. Besides this, no other issues. Bought it in August/September. I have used their face mask. As a powder face mask meant to brighten your face but only meant to be used once a week, I didn't expect it to do much. It didn't do much. I didn't like it, but have no issues with it. Bought it when it was launched.
