Acne vulgaris, more simply known as acne, is a chronic inflammatory disorder of the pilo-sebaceous unit.
About 80% of individuals between 12 and 25 suffer from acne, with consequences that extend into adulthood (acne scars, dyschromia). It is a multifactorial pathology, linked to genetic factors, immune / inflammatory, hormonal, infectious, factors deriving from lifestyle (diet, smoking, hygiene) and psychological factors (stress). Hyper-keratinisation and over-production of sebum form a cap that prevents the release of substances from the hair follicle; the sebum accumulates in the hair bulb, creating an ideal environment for the proliferation of the bacterium Propionibacterium Acnes, which triggers an increasingly intense inflammatory response on the skin. Based on a growing inflammation level, acne can be of 3 types. - Comedonic Acne: characterised by closed comedones (white spots) and/or open comedones (blackheads) and oily skin. - Papulo-comedonic and pustular acne: skin with mild inflammation; papules and pustules (papules with pus) appear on oily skins. At this stage it is possible to have consequences of scarring and temporary discolorations. - Nodular acne: skin with severe inflammation; cysts and nodules appear on the skin and increase the risk of scar formation and permanent discoloration.
"Acne reduction and its effects - treatment with KEEP photobiostimulation medical device"
The light of the KEEP medical LEDs activates cutaneous biological processes that eliminate the Acne bacteria in a non-invasive, painless and natural way.
The wavelengths, emitted by latest-generation LEDs, are absorbed by target cells and chromophores of the skin, called photo-receptors. This triggers a set of primary mechanisms, which, in turn, reactivate skin biological processes, without causing dangerous and irreversible reactions.
The light on the blue (415 nm) penetrates to the epidermis and is absorbed by the porphyrins, substances secreted by Propionibacterium Acnes. The absorption of light by the porphyrins triggers a chemical reaction, which leads to the formation of singlet oxygen. The singlet oxygen, with anti-bacterial and anti-fungal capacity, attacks Propionibacterium Acnes, the main responsible for the inflammatory process. The destruction of P. Acnes blocks the inflammatory process, reducing acne and preventing the evolution of the disease into more serious forms.
The light on red (633 nm) reduces inflammation by stimulating the intervention of anti-inflammatory cells and reducing the production of pro-inflammatory mediators.
The infrared light (830 nm) accelerates the tissue and cell repair process and the anti-inflammatory process, reducing the discoloration and speeding healing from scarring and injury.
Based on the different types of acne, Tuenda has developed treatment protocols, which, since the first session, allow to obtain effective and satisfactory results of acne reduction and its consequences. Based on accurate clinical studies, we have studied the perfect combination of wavelengths, powers and exposure times, for an effective therapy on all levels of acne manifestation.
