As the name suggests, permanent cosmetics won't wash off at the end of the day, week or year, however the amount of time it lasts varies from person to person dependent on various different factors such as: skin characteristics, use of certain medication, natural skin undertones, personal pH balance of skin (which can vary from visit to visit), diet, alcohol intake and smoking and post treatment care. The intensity of the colour will fade as your skin regenerates, which is why we strongly advise that you come back to Beautissima for a Colour Boost roughly every 6-18 months to restore colour intensity. As Mellissa says "it's important to remember that Permanent Make-Up is a low maintenance not a no maintenance treatment". This is a good thing because as we age, our preferences change and trends change. Over time your permanent cosmetics can change with you.
