Profhilo is a one-of-a-kind treatment to treat laxity, crepiness and sagging of the aging skin. It’s an injectable hyaluronic acid based bioremodulator. It is used in rejuvenation of the face, neck, décolletage, hands, arms, elbows, shoulders and knees. It is important to know that if you’ve never had this treatment before you have to start with a booster dose, which means you have to get two treatments one month apart before it starts to take effect.
