What's the difference between BHA and AHA?

BHA is oil-soluble and can penetrate into the pore exfoliating accumulated skin cells that clog pores and can also exfoliate on the surface of skin as well. It is best for skin types prone to blackheads and blemishes. AHAs are water-soluble and exfoliate primarily on the surface of the skin.

They are generally best for sun-damaged skin that is not prone to blemishes. AHA's also have moisturizing properties.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
