Polynucleotides & Hyaluronic Acid In One Treatment
Introducing Newest by Mastelli, a pioneering treatment that introduces a unique clinical profile to the UK market. Distinguishing itself from traditional injectables, Newest offers a fresh approach to skin regeneration.

What is Newest?
By harnessing the synergistic power of polynucleotides and hyaluronic acid, Newest is a high-potency injectable gel engineered to revive dehydrated and mature skin. Unlike superficial treatments, it operates at a cellular level to repair tissue and enhance skin quality from within—offering a long-term solution for aging and loss of elasticity.
The Science: How It Works
Newest transforms the skin’s architecture by stimulating fibroblasts, which in turn accelerates cell turnover and triggers fresh collagen production. The formula is further enhanced with mannitol, a powerful antioxidant that protects the hyaluronic acid from rapid breakdown while neutralising skin-damaging free radicals.
