Yes I agree with all that tinyfingers said. I had the same experience right down to a T.
Unfortunately I have very shiny skin and yes Brownpiggies, when u have shiny skin the colouring doesn't stay long. For normal skin it goes all the way from 2-5 years, depending on how fast your skin sheds its cells and whether you do a lot of facial scrubs which will fade the colour faster.
I've done the embroidery twice already and the color has almost disappeared, leaving me with faint reddish brown coloring which I have to touch up with brow pencil everyday.
Well i'm used to it already lol.
I suggest you go to Allure where they can give you a much better explanation of the 2 processes. I don't think they're very pushy, but if they are, just say you'll think about it. No worries about being pressued to buy their services ok?
If you want a good brow therapist I do recommend Allure because I think they really know their work well. And I also highly recommend bringing a friend with you who knows a lot about good eyebrow shapes.
Because the first time I did mine, I was young and naive and raw in the field of beauty. A lady who does home visits (meaning she goes to ur house to do) did it for me, and the result was bad. Unequal shape and too arched. I looked awful.
Thankfully the tattoo's faded a lot now, and I'm just getting through my days drawing using a pencil.
So, do pop a visit to Allure's and find out from the experts themselves

It's very very easy to find. Go to Tiong Bahru Station, it's on the 2nd/3rd floor of the building right opposite Tiong Bahru Plaza. The building has a coffee shop on the 1st floor. Very hard to miss. And it's smack right outside the MRT exit.
Alternatively, if you're coming out from the train, just turn right. (Left will lead you to TBP).
