NEWEST Polynucleotides + Hyaluronic Acid in Berkhamsted
At Dermaline Aesthetics, we offer NEWEST by Mastelli — a unique injectable that combines polynucleotides with hyaluronic acid (HA) to improve hydration, elasticity and overall skin health with natural-looking results.
What is NEWEST?
NEWEST is the only UK treatment pairing regenerative polynucleotides with hydrating hyaluronic acid in a single protocol. It focuses on skin quality rather than adding bulk.

How polynucleotides support repair
Polynucleotides signal fibroblasts to support collagen and elastin, encouraging cellular-level renewal. Mastelli’s NEWEST uses highly purified, fish-derived DNA fragments that are injected into the dermis to aid regeneration.

NEWEST combines polynucleotides with hyaluronic acid to boost hydration, elasticity and overall skin quality.
What hyaluronic acid contributes
HA binds water (up to 1,000× its weight), restoring moisture for plumper, smoother skin. In NEWEST, HA hydrates while polynucleotides get to work on repair.
