I believe the answer is:

rubber

I'm a little stuck... Click here to teach me more about this clue!

This clue might be a double definition.

'look buffer' is the first definition.
'rubber' can be an answer for 'buffer' (I've seen this before). I'm not certain of the 'look' bit.

'latex' is the second definition.
(rubber is a kind of latex)

'in' acts as a link.

Can you help me to learn more?

(Other definitions for rubber that I've seen before include "Match of three successive games at bridge" , "Masseur - series of bridge games" , "in the stationery cupboard?" , "Elastic substance; set of bridge games" , "Boring, obsessive type" .)
