Non surgical nose job. Can I use a pore strip?

As long as your nasal tip is not sensitive, you could consider extractions by an aesthetician, or perhaps a strip as you suggest. The filler was placed deep to your nasal skin and should not be affected by a skin treatment. Hope this helps! Sincerely, Dr. Joseph

Hi Thuy.  You should probably check with your injector to be sure, but most of us would say no worries, gently cleanse the skin and use whatever topical treatments you would like, as long as you don't push the contour in.  Always massage away from the face and/or up and down the length of the nose when possible.  When you apply the pore strip, pinch it on evenly from both sides and then lift it off symmetrically to assure none of the filler can shift.
The filler will amalgam with your tissue over the next few weeks and then you can do whatever yo want for your nose without worries.
Clean it up and enjoy your new nose contour!  If you love it, consider using Bellafill to make the correction last years next time!
Hope that helps!
Best, Z
