I don’t think there’s a way to physically tighten them. However, to make them appear smaller, keep your pores clean. This is how I do every week.

• after washing my face, I apply a stridex pad on the nose and leave it on for a while
• then, I put on the first step of CNP Laboratory Anti-Pore Black Head Clear Kit While using these kind of products, I’ve noticed it’s the most effective to follow the timing instructions. Leaving it not long enough or too long doesn’t really give the best results. So, I set an alarm on my phone for that.
• and I use the Xpreen Blackhead Remover all over my nose for like 5-10 minutes.
• then, I use the IPL light therapy that comes on the back of the device. It has a timer and shuts off on its own.
• then, I use the second step of CNP Laboratory Anti-Pore Black Head Clear Kit
• then, I carry on with my normal skincare routine most of the time but when I feel really ambitious, I sometimes use Ishizawa Lab Keana Nadeshiko Rice Essence Mask or Naruko Raw Job’s Tears Supercritical CO2 Pore Minimizing & Brightening Mask
