The healing process


Healing is the skin’s response when it has been broken by a wound (heat or chemical burn, cut, surgery) or the direct action of free radicals (sunburn, ionising radiation etc). The first stage in the healing process is inflammation combined with redness, swelling and pain. The blood and lymphatic vessel secretions flood the damaged tissue immediately after the injury. When the blood flow slows down, weeping protects the wound against infection and ensures that it is clean. The white corpuscles penetrate the inflamed tissue, clean out the foreign bodies left by the injury, kill the bacteria and release substances that attract other leucocytes or white corpuscles.

Once the inflammation calms down, the constructive phases of the healing process get underway. They involve new cells that are identical to those that were damaged being reproduced or replacement by a scar of the tissue that the body cannot regenerate.

However, the speed of healing may vary depending on the size of the wound and also on age, diet, stress and the emotional setting. Some people also heal better than others, as healing does require the patient’s cooperation in order to be quick and gentle.

Acne cause and consequences :


illustration acne

Acne is caused when hair follicles become blocked and is a three-stage process:

 

- In the first stage, the sebaceous glands are over-stimulated, generating an excess of sebum, creating ‘oily skin’.

- Stage two occurs when micro-blackheads form, with this happening due to excess sebum and its composition being changed.

- In stage three, the sebaceous glands become inflamed, as a result of a bacterium being present on the skin: Propionibacterium acnes.

 

The following three problems need to be addressed:

- Reduce excess sebum.

- Stop micro-blackheads from forming.

- Combat inflammation by limiting the presence of Propionibacterium acnes.

Free radicals, one of the contributing factors to skin aging


Illustration radicaux libres

Free radicals are naturally and continuously produced and are vital to the body. In fact, every time we breathe, the body utilizes oxygen in such a way that free radicals are formed. Free radicals are involved in the energy production process, for example. They play a role in cellular respiration but also in the immune mechanisms, helping to prevent bacterial or viral invasion. These oxygen molecules contain a single electron. These molecules will do anything to find a partner and constantly seek out other molecules in their environment with which they can combine, grabbing the electron that they need from them. The stripped and oxidised molecule then becomes a free radical and hastens to strip its neighbour, in turn making it unstable. These chain reactions are dangerous for the body. When an excess of free radicals are produced, they start to damage cell walls, protein and DNA. They cause significant damage, specifically in terms of skin aging. This is known as oxidation or oxidative stress.

Many factors contribute to the excess of free radicals in the body, such as certain stress-related situations linked to the environment or an unhealthy lifestyle. Other external factors such as pollution, smoking, drinking and the sun increase the build-up of free radicals. Fortunately, there is a defence system that protects against excessive free radicals and neutralises them: antioxidants. They are either produced by the body or come from vitamins and trace elements and take up the task of constantly eliminating excess free radicals.

Hyperpigmentation


Melanin, a brown pigment produced by the skin’s cells (melanocytes) is the source of hyperpigmentation marks, which in particular develop with age on the face, neck, hands, shoulders and chest.

While sun and skin aging are closely linked in the skin hyperpigmentation marks development process, individual photo-sensitivity and other factors play a part in their development: taking medication, using perfume, particularly when exposed to the sun, and occasionally for women, their hormones (pregnancy mask and oral contraceptives).

When skin is exposed to the sun’s rays, a cascade of enzyme reactions triggers melanin production and in the long-term leads to these unsightly spots forming.

 

Tyrosinase limits the biosynthesis of melanin. Inhibiting this enzyme helps to limit melanin production, notably in the case of skin hyper-sensitivity to the sun.

What is cellulite ?


 

Cellulite is in fact a lipodystrophy. It is a fatty deposit characterised by its sub-umbilical location in women and by the fact that it establishes itself during puberty and that fresh outbreaks occur following pregnancy and the menopause. Cellulite is a major aesthetic problem for women and is a frequent reason for medical consultations that doctors are duty bound to address, as cellulite treatments are now effective.
