The permanent treatment can last up to 5-6 years. However, the exact period varies according to your skin type, the treated area, and the chosen color. The darker the color, the longer it lasts. Immediately after the treatment, the color appears dark; within 4 to 10 days the color weakens from 10% to 20%. Ultra-violate exposure from sun or tanning booths, various drugs, excessively dry skin, and smoking are all factors that may affect the color. It is essential that a sun block be applied over the permanent make-up area at any time that you are exposed to the sun or a tanning bed to prolong the effective life of these procedures.
