Hyaluronic Acid is a high-performing active ingredient made of different, mixed molecular weights: extremely low, low, medium and high molecular weight. 

The low and extremely low molecular weight penetrate deep into the skin. They are fundamental for an intense, lasting lifting action, guaranteeing the plumping and lifting effect that wouldn’t be possible with high molecular weights only. 

The medium and high molecular weights, which are equally important, work on the surface of the skin and assure intense hydration for the part most threatened by external agents.

This product is a focused treatment against wrinkles, for an immediate and long-lasting lifting effect while reshaping the face and décolleté.

Excellent used pure as a face serum, mixed with your usual cream for an anti-ageing booster, or to make your own cosmetics. 

Our Pure Actives are not photosensitising! You can use Hyaluronic Acid morning and evening, even in the summer!

Apply it morning and evening to a cleansed face.

You can use it in two different ways:

1) Pure, instead of or before your face cream. Apply 2 drops of product directly on your face and rub in until completely absorbed.

2) As a booster. Add 1 or 2 drops of product to your favourite face cream or serum. It will improve the efficacy of the cream or serum and make the texture light and easy to spread. 

Hyaluronic Acid is perfect for anyone looking to supplement their beauty routine with a natural active ingredient able to provide an immediate tensor effect, leaving skin supple and moisturized.

Our Pure Actives are precious and therefore it is really important to protect their content, to ensure long-lasting, maximum effectiveness. For this reason, we’ve chosen bottles with an anti-UV protective screen. And there’s more! The bottles are made of re-bottle post-consumer recycled plastic, which is used plastic that is regenerated into new containers in order to reduce waste on our planet. This material is even greener than normal recycled plastic, which is usually derived from industrial waste!

Bottle: PET1 - unsorted plastic 

Top: O07 - sorted plastic

Three molecular weights

High molecular weight : its size does not allow it to pass through the skin, but this allows the molecule to act on the surface by providing moisturizing and film-forming action, preventing the naturally present water on the skin from evaporating.

Medium molecular weight: it is absorbed more easily even though it cannot reach the deeper layers, but it allows the passage of water to maintain optimal hydration.

Low and very low molecular weight : the reduced size of hyaluronic acid molecules allows them to reach the deeper layers and plump and nourish the natural matrix already present.
