Mind full Meditation
Depending on what method of meditation you are practicing there are different options.

If you are practicing Samatha (tranquility) meditation, simply return back attention to whatever primary meditation object you have chosen, e.g. the belly or entrance to the nostrils.

If you are practicing Vipassana (insight) meditation, observe the tingling feeling and note it as "feeling, feeling" or "tingling, tingling", while keeping attention on the phenomena. Note it 2-3 times and then return attention to the feeling of the rising and falling of the abdomen (primary object).

In Samatha meditation one is gently shifting attention away from all other phenomena except the breath.

In Vipassana meditation one is changing object according to whatever arises at the sense doors.

For more info on how to meditate I would suggest Ven. Yuttadhammo's booklet and video series on how to meditate (Vipassana meditation).
