It's totally normal to feel underwhelmed right after, especially if you have very congested pores. The treatment does remove surface debris, but if you have deep, oxidized blackheads (the hard ones), they might not all come out in one go. The lymphatic drainage and hydration part of the facial can also cause a bit of temporary swelling or plumping, which can actually make pores look larger for a day or two until everything settles. Give it 48–72 hours – your skin is essentially reorganizing itself. Also, make sure you're not using heavy moisturizers right after; stick to lightweight, non-comedogenic products to let the treatment do its work.
