Il termine antiossidante si riferisce a tutte le sostanze in grado di contrastare l’ossidazione causata dai radicali liberi, responsabili dell’invecchiamento cellulare. Nello specifico, gli antiossidanti che si applicano sulla pelle aiutano a contrastare il foto invecchiamento, idratandola, meglio se con all’interno un SPF che scongiuri l’azione, nociva, dei raggi ultravioletti del sole. Utilissime anche le creme specifiche per la notte, capaci di aumentare il nutrimento mentre si dorme – momento in cui la pelle è molto reattiva – contrastando rughe e rendendo la pelle più elastica.

Prima di parlare di antiossidanti, conosciamo meglio i radicali liberi

I radicali liberi sono la causa dello stress ossidativo attraverso una reazione di ossidazione, detta a catena. I radicali liberi, ovvero i prodotti di scarto delle nostre cellule, altro non sono che molecole instabili, fisiologicamente prodotte durante le reazioni biochimiche che avvengono nelle nostre cellule. Queste molecole instabili strappano elettroni da altre molecole per raggiungere uno stato di maggiore stabilità. Tale processo è la causa dell’ossidazione che, se non controllata, può intaccare le strutture biologiche,come il collagene, e di conseguenza provocare l’invecchiamento. A questo aggiungiamo gli stress ossidativi esterni, come l’inquinamento, la luce blu e i raggi UV, e le cattive abitudini, come fumo, alcolici e una cattiva alimentazione, che aumentano la produzione di radicali liberi, nocivi per il corpo e la nostra pelle.

Quale è lo scopo degli antiossidanti?

Gli antiossidanti proteggono la cute, prevenendo l’azione dei radicali liberi, ancora prima che questi raggiungano le cellule negli strati profondi dell’epidermide. Ne esistono due classi: gli endogeni, prodotti internamente dal nostro organismo, come gli enzimi acido urico, coezema Q e glutanione. Gli esogeni sono invece quelli esterni, cioè non prodotti dall’organismo, che vanno assunti via integratori o attraverso creme specifiche, per favorire il processo di detossificazione. Quest’ultimi sono gli antiossidanti naturali più conosciuti, come le vitamine A, C ed E, i carotenoidi, i tocoferoli, i polifenoli, i flavonoidi, l’acido lipoico e il selenio.

Come agiscono gli antiossidanti nelle creme

Bisogna, innanzitutto, con l’aiuto di un esperto, capire quali parametri la nostra pelle ha davvero bisogno. Si parla in termini di pH e di concentrazione. Assumerli via crema è un’azione preventiva sull’eventuale comparsa di rughe e discromie. Per questo SOTHERGA ha creato SOTHERGA LAB, il servizio online di consulenza gratuita da parte di un medico che, dopo aver letto l’anamnesi digitale del paziente, analizzerà le risposte e creerà uno skin regimen curativo e personalizzato su misura per la pelle del volto, da potenziare, a piacere, con trattamenti in clinica.

Facciamo qualche esempio

La vitamina C è la più popolare. In grado di prevenire lo stress ossidativo, ha però bisogno di una cura specifica, in caso di pelle reattiva. La vitamina E, più delicata, è invece in grado di proteggere le membrane cellulari dalla perossidazione lipidica, anche in presenza di derma secco o disidratato, come nel caso della couperose. La niacinamide, o vitamina B3, è un ottimo antinfiammatorio; ripristina la barriera cutanea e la lenisce nel tempo, soprattutto per la pelle a tendenza acneica. Il coenzima Q10 è la sostanza antiage più nota, capace di ridurre il naturale declino delle cellule poiché, con la sua azione antiossidante, va a inibire l’ossidazione dei lipidi.

Per un boost di antiossidanti, c’è l’I.V. Therapy

Con il termine I.V. Therapy si intende la somministrazione, per via endovenosa, di una soluzione che contiene un mix di vitamine, minerali, antiossidanti e aminoacidi, appositamente combinato dal medico dopo un’attenta valutazione delle esigenze del paziente. Queste sostanze, spesso, hanno un assorbimento molto limitato, se somministrati per via topica od orale. La I.V. Therapy è quindi un ottimo modo per somministrare in alte concentrazioni antiossidanti nel nostro corpo, soprattutto in periodi di forte stress e nei cambi di stagione, poiché la somministrazione in vena velocizza i tempi.

Our treatments

Blepharoplasty

In some cases, the aesthetic doctor may recommend a solution that allows the patient's needs to be met through cosmetic surgery, always respecting a natural and personal aesthetic standard.

Biorevitalization

Biorevitalization is an injection treatment based on nutrients that stimulate the action of fibroblasts and promote the production of new collagen, which is essential to reduce wrinkles and restore skin elasticity.

Bio-filler

Bio-fillers are latest-generation treatments composed of free hyaluronic acid mixed with peptides (small chains of amino acids).

Filler

The hyaluronic acid used in the filler is a cross-linked hyaluronic acid. The higher the level of cross-linking, the denser and more textured the filler becomes, resulting in a longer absorption time.
