New Improved Formulation.
Our original Hyaluronic Acid formulation used sodium benzoate and potassium sorbate as the preservative system. However a small proportion of the population has a sensitivity to, in particular, sodium benzoate, which is evidenced by skin reddening. We have now replaced the preservative system with a mild skin friendly preservative – Dermosoft 1388 which is tolerated well by all skin types.
Our HA serum is now available in a chrome and acrylic airless bottle or a dropper bottle. Make your preferred container selection from the drop down menu.
Hyaluronic Acid Serum
Hyaluronic Acid occurs naturally in the deeper layers of our skin (the dermis). It helps to keep skin smooth and “plump” through its ability to hold up to 1,000 times its weight in water. and it plays a critical role in the rapid repair of wounds and other skin conditions.
The stratum corneum is the uppermost layer of the skin and is composed of densely packed disc shaped cells which form a barrier to keep contaminants out and keep water in. As we age the integrity of this barrier fails, to a greater or lesser degree, and the consequence of this loss of integrity is an increase in the amount of water lost from the skin (trans- epidermal water loss or TEWL). As a result of increased TEWL the skin becomes drier and loses volume making the complexion look drawn.
Applying Hyaluronic Acid to the skin will immediately hydrate the skin and restore some of the lost volume. As the skin is hydrated the skin will plump up leading to a reduction in the appearance of lines and wrinkles. But the application of hyaluronic acid doesn’t just give a temporary hydration boost, it can help repair the damaged stratum corneum so that TEWL is progressively reduced.
The diagram above shows the action of hyaluronic acid. As well as hydrating the skin the HA , as it penetrates the skin will circulate amongst the cells in the layer imediately below the startum corneum and will create a reservoir of moisure that the skin can draw on to keep the uppermost layers hydrated.
Our serum contains two types of HA. Standard Molecular Weight Hyaluronic Acid (SMW) and Low Molecular Weight (LMW) Hyaluronic Acid. The SMW form is the standard weight used in the cosmetics industry as it has the capacity to form a gel like structure and so is the basis for HA serums. The LMW can not form a gel and remains water like in consistency and so is not used for serum bases. However the LMW possesses the ability to penetrate the skin more effectively than SMW (due to its smaller sized molecules. We combine the gelling abilities of SMK with the penetrative properties of LMW to create the perfect serum.
All of our moisturisers contain Hyaluronic Acid and pure Hyaluronic Acid forms the base for our line reducing serums.
The serum can be applied direct to the skin or added to your existing creams and lotions.
