Hirudoid - skin layers

Functions of the skin

To understand the process of healing, we need to have a basic understanding of the way skin functions. The skin has three major layers: the epidermis, the dermis, and the subcutis.

The top layer of the epidermis is actually dead skin. Every few days this layer is shed off and replaced by new cells.

The dermis is a supple layer of connective tissue matrix, which makes up 90% of the skin’s thickness. This matrix consists of ground substance composed of mucopolysaccharides (MPS) and other proteins. The MPS play an important role in the tissue regeneration of the skin as they have a stimulating effect on the connective tissue cells.

The subcutis is made up of mainly fat and is responsible for insulating the body, but has no role in the repair of tissue.


Hirudoid - Bruises
Hirudoid - Bruises

A bruise is caused by blood trapped under the surface of the skin. It is caused by an injury that crushes small blood vessels but does not break the skin. Blood seeps out from these blood vessels into the surrounding tissues. Bruises cause skin discolouration and are often painful and swollen.

Healing process of bruises

Bruises will heal in time as the body reabsorbs the blood. Initially the bruise is a pinkish red colour that can be tender to touch. Within hours it will turn a dark blue or purple colour due to the breakdown of haemoglobin that is found in the blood. Finally, as the healing process continues it changes to a yellow colour and fades until it completely disappears. Depending on the severity of the bruise it can take anywhere from a few days to a few months for a bruise to completely fade.

People who bruise easily

Some people have more delicate blood vessels meaning it may only take a minor bump to cause a bruise. Additionally, blood vessels become more fragile as we age and our skin becomes thinner. When an injury occurs the skin has less cushioning to protect the more fragile blood vessels. Medications that are designed to thin out the blood and those that cause skin to thin can also exacerbate bruising.

It is a fact that women bruise more easily than men.

Some vitamin deficiencies are associated with an increased tendency to bleed such as iron, vitamin C and zinc deficiencies.

Other healing properties of Hirudoid

Hirudoid contains MPS (mucopolysaccharides) which is similar to the body’s naturally occurring MPS found in the dermis layer of skin. MPS accelerates healing in the following ways:

  • Improves blood flow to the area
  • Accelerates the absorption of bruises
  • Reduces swelling and inflammation



Treatment of scars

The MPS in Hirudoid is able to attract water and therefore loosen the connective tissue, preventing a dense accumulation of the fibres, which create a thick scar. Hirudoid softens scars, increases flexibility of the scar tissue, reduces redness and results in a better cosmetic appearance.

Reduces the healing time of sprains


Anti-inflammatory effect on veins
