(Anti-aging)
Our own skin produce Hyaluronic acid but as we age it decrease, this serum will therefore help to moisture and helping our cells retain as much of it as possible so that our skin feels and appears hydrated, plump and healthy. 
When the skin is hydrated, lines and wrinkles (even the deeper ones) appear diminished, so it is a great serum for those with ageing skin who are desperate to stay on to their youthful perkiness.
