Feather touch requires an additional colour refresh approximately every 12-18 months to keep those brows looking fresh.
Combination brows and powder brows will need retouching anywhere from 12-24 months.
The quality and longevity of cosmetic tattooing cannot always be guaranteed as some skin tones hold colour longer than others, while others fade leaving a light residue in the skin. Factors that may affect the longevity of your brows include sun exposure, metabolism, oily skin, age and the use of active skin care products such as Retin-A.
