Discoloration

 

A skin discoloration is an imperfection of the skin due to an abnormality in the pigmentation of our skin.

An accumulation of melanin in some parts of our skin (hypermelanosis) involves the hyperpigmentation of the skin, with the appearance of darker skin spots. Hypermelanosis may be due to factors such as post-inflammatory outcomes (wounds, burns, acne, dermatosis, lupulus), hormonal factors (e.g. melasma in pregnant women), systemic diseases (Addison's syndrome), photo-ageing (lentigo or sunspots), chrono-aging (lentigo or senile spots), intake of substances, neoplastic processes (keratoses), genetic factors (e.g. ephelides), and is due to an inhomogeneous distribution of melanocytes (cells secreting melanin) on the skin and a lower ability of our body to regulate their activity of melanogenesis. There are several types of hyperpigmented skin discoloration.

- Ephelids:they are small spots that appear above all on the face and arms of the subjects with very light skin (phototype 1); they depend on genetic factors, they are inherited and they are affected by sun exposure. They are formed by the oxidation process of the ultraviolet rays triggered on the skin and tend to disappear in winter.

- Solar lentigo:they are irregularly yellow-brown patches due to a trauma due to excessive exposure to the sun. UV rays can lead to premature skin ageing (photo-ageing) associated with changes in the mechanisms of melanogenesis and hypermelanosis. Excess melanin is not always distributed normally, but accumulates in some areas leading to the formation of hyperpigmented spots.

- Lentigo senilis:similar to solar lentigo, are a condition related to ageing of the skin. With the passage of time the regenerative capacity of our cells decreases; the melanocytes are distributed in an inhomogeneous way, leading to an increase in melanin where they are more concentrated. A strong correlation between photos of acute and chronic exposure of the past and the appearance of sunspots has been demonstrated; in fact, while solar lentigo is the result of a sun exposure trauma and can already appear from age 35, age spots appear from age 40 and up and depend on a mix of slowing regenerative processes for chrono-ageing and accumulation of damage from exposure to ultraviolet rays over the years. Both lentigo conditions appear mainly in areas exposed to the sun, such as face, neck, décolleté, hands.

- Melasma or chloasma:these are brown or brown flat spots or patches, located on cheeks, temples and foreheads. They are due to hormonal factors, which is why they mainly affect pregnant women (pregnancy chloasma). In women they tend to disappear once the hormonal stimulus is interrupted, while in men it rarely disappears. Accentuated by exposure to the sun, it seems to be due to an alteration of the melanocyte activity, responsible for an over-transfer of melanin to keratinocytes.

- Post-inflammatory hyper-pigmentation spots: they are brown and irregular patches that are formed as a result of an inflammatory process due to injury (wounds, burns) or other causes of inflammation (acne, lupulus, erythema). Following a lesion or other type of inflammation, melanin may accumulate in the affected area. Once the inflammation process is over, local hypermelanosis does not fade over time, leaving a hyperpigment mark in the skin.

- Keratosis: looking similar to lentigo, but slightly raised and rough to the touch, are caused by the damage caused by photo-ageing. Very often, precancerous forms can evolve into benign or malignant tumour forms of the skin. For this reason we recommend a checkup by the dermatologist.

Against discolouring - the illuminating treatment with

KEEP photobiostimulation medical device.

 

The combined action of the KEEP and DEPIGMENTAX medical LEDs, for the non-invasive, painless and natural treatment of skin discolorations.

Through extensive clinical studies, Tuenda has devised a treatment protocol that combines the effect of LED therapy with the application of a concentrated pre-treatment DEPIGMENTAX for the reduction of skin discoloration. Thanks to the LED light action at a precise wavelength and to the alpha-hydroxy acids contained in DEPIGMENTAX, KEEP stimulates the metabolism and physiological homeostasis of the treated tissues, standardising them and normalising their physical and functional appearance and characteristics. Following the cycle of sessions it is possible to notice a reduction in the number of hyperpigmented spots and a greater chromatic uniformity of the treated skin.
