1. If you fill your brows in every day (or have regular brow tint) and feel naked without your brow makeup then you are most probably ready for permanent makeup brows!
2. If you feel naked without your lipstick or never leave the house without an eyeliner, then you are ready for permanent lip blush or permanent liner!
What if somebody told me that my brows are too thin/too sparce/too light, and now I think that they may need something done. But I actually never use makeup on them. Should I have permanent makeup brows done?
No, if you don't fill in or tint your brows on a regular basis I do not recommend to go straight for permanent makeup brows, as these will stay on your face for quite some time. I strongly believe that you should be definitely sure that you like the new shape and definition of the new brows.
I would advise you to have HD brows or Henna brows done first, so you can see the new shape and look and decide whether you like it or not. If not, it will wash off within a few days! If yes, then you can consider to have permanent brows done.
My lips don't have defined border/have pale spots and I would like to fix it, but I never actually wear lipstick. Can permanent lip blush help?
Yes, it definitely can! I would use a very natural pigment in this case which would even out the colour and make the border more defined without looking like you have lipstick on.
