Which most hydrating non comedogenic substance for makeup fixing on oily skin wide pores face?

Hydrating substance. Thank you for your question. Unfortunately, your question is not very clear but I believe you are looking for a substance that is hydrating but also non-comedogenic. Glycerin and dimethicone are two noncomedogenic substances that are considered hydrating. There are many others. The second part of your question is unclear, but noncomedogenic substances by definition will not clog or widen pores.
