Nyx Professional Makeup Gotcha Covered Natural Concealer Pencil For All Skins, Medium Olive, 0.04 Ounce

What is the difference between alabaster & porcelain? which is lighter and which undertones does each contain? are these the lightest shades? thanks!!

How light a skin tone is this. I have a fairly olive complexion & want something 2 x my normal skin tone

Is this product any good?

Does this replace their Wonder Pencil they stopped making? Is it the same?
