However, the chances of success are strongly linked to the type of stains that you want to eliminate and the triggering causes: if in some cases it is possible to intervene on the factors responsible or favoring the onset of dyschromias, in other cases the intervention is more difficult .
of the face refers to areas characterized by alterations in skin color (discoloration) - more or less large and with more or less regular margins - which can appear on the face. Depending on the triggering cause, these spots may be of a different color and appear darker than the color of the skin (in these cases, we speak of hyperpigmentation), or they may be lighter (for example, white spots on the skin), or again , be red (red spots on the skin). The latter, generally, are attributable to skin disorders and pathologies and will not be considered in this article.
What are the Causes and Triggers?
One of the main causes of spots on the skin of the face - in particular, of hyperpigmented spots - is represented by skin aging. However, the inevitable and completely physiological aging process is not the only possible cause responsible for the onset of discoloration. cutaneous. In fact, these can also be caused by:
- Some types of pathologies, such as pityriasis versicolor, vitiligo, etc. (skin spots of a pathological nature will not be considered in this article);
- Taking certain types of medications;
- Genetic and hereditary factors (this is the case of freckles or freckles);
- Hormonal factors (as in the case of the so-called pregnancy mask).
Then there are some environmental factors and unhealthy vices that can greatly contribute to the appearance of spots on the face, among which we remember:
- Excessive and unprotected exposure to UV rays, both natural (sunlight) and artificial (tanning lamps);
- Dangerous vices such as smoking;
- Smog.
Leaving aside the causes of a pathological nature and those on which it is difficult to intervene, attention will be focused on the external factors mentioned in the above list on which, however, it is possible to intervene, even in a preventive manner.
with an adequate protection index (in this regard, let's dispel the false myth according to which sun products with a high protection index cannot be tanned).
These ingredients can act mainly through two mechanisms of action:
- Interference with the production of melanin by the appointed cells (melanocytes);
- Interference with the transport of the melanin pigment from the melanocytes that produced it to the superficial skin cells.
Among these ingredients, we mention some:
- Azelaic acid: it is a substance of natural origin that can be found inside wheat, barley and rye and produced by a yeast called Pityrosporum ovalis. It works by interfering with the production of melanin in melanocytes.
- Glycyrrhizin: this substance also interferes, blocking it, with the production of melanin and is of natural origin as it is contained in significant quantities within the licorice root extract.
- Arbutin: another substance of natural origin (present inside the bearberry) which interferes with the synthesis of melanin.
- Kojic acid: it also affects the production of melanin, it is produced by fungi belonging to the genus Aspergillus.
- Ellagic acid: contained in the pomegranate extract, it acts on a particular enzyme involved in the synthesis of the melanin pigment - tyrosinase - hindering its action.
Of course, these are just some of the ingredients that can be used in cosmetic formulations designed to counteract hyperpigmented spots on the face. In the vast majority of cases, face cosmetics designed to combat skin blemishes not only contain active ingredients with a lightening action, but can be enriched with:
- Moisturizing ingredients;
- Ingredients with a nourishing function;
- Ingredients that possess antioxidant action (for example, vitamin C);
- Emollient ingredients;
- Solar filters;
- Other ingredients - including plant extracts - that can help make facial skin glow.
We remind you, however, that to obtain appreciable results, such cosmetics must be used consistently and regularly and that, in any case, however much they can alleviate the problem of hyperpigmented spots on the skin of the face, they will not be able to solve it completely.
;These are treatments not suitable for everyone and certainly not without possible side effects and contraindications. Therefore, it is of fundamental importance to contact doctors and professionals in the sector.
