oh yes, no regrets, all done for me. Initially it was vanity, now becoming more a necessity as eyesight/accuracy not as good as they once were. Great without makeup, great with makeup when required.
I had mine first done several years ago by someone who worked for private healthcare mainly tattooing cancer/chemo patients with eyebrows, eye liner and nipples - I knew I was in good hands. She took a long time measuring my brows minutely, following my natural brow line, drawing them then showing me how they would look - yikes.
I've had them touched up over the years, this person also does chemo/cancer face and nipples and covers scars - the tattoos do fade and how long depends on your body.
Areas numbed, you feel pressure (you are lying on bed/chair). easy aftercare.
When healed your brows will start to look as intended. I'm red /salt/pepper hair, blue eyes, pale skin and was terrified I would end up with the startled look so many people end up with. But the practitioner listened to me and kept saying they will look as you described you wanted them - My description was not dark, I want a natural taupe type shade and more definition than colour. And they are - love them. Eye liner too, only black and you can hardly see the line - but the overall look is eye definition - love them.
As my eyelashes are fair, I have them dyed regularly, when first done the combination of eye liner plus dark lashes looks great (in my opinion).
Now mid 70's and will get my tatts touched up if I feel the need again

"Micro-pigmentation is a refined variation of cosmetic tattooing in which hypoallergenic, pharmaceutical grade pigments are introduced into the skin in order to create a shadow of colour that mimics the most perfectly applied make-up"
certainly NOT carcinogenic.
