Hyaluronic acid (HA)- A humectant

Hyaluronic Acid is a substance which is formed by skin cells and is part of the connective tissue of the skin.
As we age, the skin’s ability to produce HA depletes and the levels gradually fall. Skin becomes drier and prone to wrinkles as the process of producing news cells and fibres slows.

Seaweed has been used for decades in Japanese and Korean skincare as it has been shown to not only contain high levels of HA, but in an extractable, useable form. This can help to speed up the cell renewal process, acting as a protein building block and increase the skin’s lost elasticity by supporting collagen, keratin and elastin.
Replacing the skin’s dwindling stock of HA will help to smooth lines and improve texture and firmness in the skin.
One of its main functions in the skin, is to retain moisture, (it has been shown to bind over a thousand times it’s weight in water) and this makes it an important part of re-hydrating ageing and sun-damaged skin.

We harvest our own seaweed and collect only the firmest, healthy strands for distillation. The plants are distilled immediately, with no time to dry out and lose vital nutrients. This produces a glistening gel-like product, that we bottle as hydrosols or use in our Rose and Seaweed Moisturiser.

Which Materials And Why
Glass: Glass is our preferred packing option, it is easy to sterilise, is chemically resistant so the product inside keeps well. It is simple to clean and re-use, however, due to its weight, it is not alway a realistic option if goods are to be posted. It can smash easily and adds considerably to the weight and cost of packing. When we don’t use glass, we use PET and HDPE plastics as an alternative, or, occasionally, aluminium.
PET Plastic: ( polyethylene terephthalate) is lightweight, resealable, shatter-resistant and recyclable. Recycled polyethylene terephthalate is known as RPET, and it is the most widely recycled plastic in the world.
HDPE Plastic: (High-Density Polyethylene), is a plastic linear polymer with a high specific density which is light with a high tensile strength. It is is relatively hard and can hold very hot liquids without being affected. It tends to have an opaque finish. This is a good barrier material as it does not contaminate the contents and is extremely resistant to chemicals including acids, alcohols, aldehydes, esters and oils. These are an easy material to recycle and are accepted at most recycling centres.
Aluminium: This keeps the product sterile, doesn’t attract moisture (which will contaminate the product), and protects from heat damage (this is relative – direct heat or an hour in the sun will melt whatever is inside!). It is one of the world’s most recycled materials and is both strong and lightweight, so an excellent choice for anything that will be travelling long distances.
HDPE has a lower specific density than PET so they are separated during recycling. The amount of plastic used in shopping bags has reduced by around 70% in the last 20 years mainly due to people recycling these, although demand in India and china are still increasing. It is important to recycle these plastics as they take years to decompose if they are not shredded and re-used.
