Immediately following your microneedling session your skin will appear pink and flushed. This redness subsides by the next day (although it can last a day or two more depending on the microneedle penetration depth and the number of overlapping passes used on the treatment area), but microneedling is best done as an after-work procedure. In addition to the redness, you may also have some mild swelling and a feeling of tightness across the treated areas.
