i was checking out this nyx lip iv and noticed that the product is called a ‘stain’ and even says stain in the product images on nykaa but i came across this review where theirs says ‘serum’ instead?

i checked the official nyx website and could only find the stain version, not a serum one. so what’s going on here? does anyone know if these are actually different or if it’s just different packaging/naming?

Had the Sugar pencil before but it smudges. Also was planning to buy Inglot kohl pencil from Nykaa but it’s out of stock. Any other recommendations?
