Polynucleotides are wonderful regenerative treatments that can benefit anyone's skin due to the cellular-level stimulation of fibroblasts (the cells that lead to collagen and the skin's supporting structures).  They are derived from fractions of salmon DNA (no salmon are harmed in the making!) which is remarkably similar to ours, and they have been used in medicine for years for in tissue and cartilage growth due to their anti-inflammatory and regenerative properties.  They can be brilliant in the under eye area, especially for crepiness and dark circles, and for adding back skin sponginess, are often combined with profhilo, skinboosters or fillers to help create a refreshed, rejuvenated look in the face in general.
