How long dermal fillers will last depends on the nature of the product, the area being injected, and the patient. Cara Mia Medspa will assess the personalized components of dermal filler duration during the consultation but there are some general rules. Deeper injections tend to last longer, sometimes even longer than 12 months. If a patient opts for a shorter-term treatment they may consider switching to a longer-lasting product for subsequent injections provided they are happy with their results. In order to smooth the skin and fill in lines and wrinkles closer to the skin, your doctor may choose a thinner product. There is a possibility that these products will be metabolized more quickly and last for 6-12 months. A filler tends to go away faster in areas of the face with more movement, such as the lips because the constant movement of muscles dissolves the filler more quickly.
